The economic evaluation of beef cattle breeding
Říhová, Monika ; Toušová, Renata (advisor) ; Jan, Jan (referee)
The objective of this dissertation is the evaluation of economic indicators of beef cattle farming on a specific family farm in the time period from 2013 to 2015 in Bukovina u Čisté village, Semily District. The family focuses on a crop and livestock production. The farming takes place on 110 hectares of land, the fertile ground makes 54 ha. The livestock production concentrates on breeding cows without any milk production and the bulls fattening. The amount of cows was 23 pieces to 27 pieces in the period from 2013 to 2015. Because of the crossbreeding the cows following breeds are represented: Czech Pied cattle (20 %), Limousin (72 %) and Charolais (8 %). In the bulls fattening area were more breeds represented caused by the purchased bulls. Breeds represented: Limousin (32 %), Czech Pied cattle (42 %), Blonde d Aquitaine (1 %), Aberdeen Angus (23 %) and Holstein cattle (3 %).
The processing and evaluation of economic results was prevented by factors affecting the economics of farming. In the reproduction part are the factors - the calving interval, the age structure of the cows and the scatter of births during the year. The bulls fattening part contains the research of the bulls breeds representation, age structure and carcass weight. The economic indicators consist of the evaluation of the costs, revenues, profit and the level of profitability. The breeding was evaluated in the conclusion of this dissertation and the suggestions for improvement was recommended.
The calving interval of the cows in 2013 lasted on average of 408 days, in 2014 decreased by 9 % to 373 days, and in 2015 decreased by further 9 % up to 337 days. Heifers reached 3 years of age at birthing. The oldest cows were 11 years old. The biggest group of cows was at the age of 7 years with a 27 % share. The Breeders preference is the calving during the winter to spring time period. In 2013 the birthing period lasted from February to July, in 2014 from March, except June and August, until October and in 2015 from February to August. For the entire period was 76 % of births in the barn and 24 % of births on pasture. In the entire period 76 % of births happened in the barn and 24 % of births on pasture.
The bulls fattening contained 42 % of own breeding and the next part consist of purchased bulls. The largest group of bulls are Czech Pied cattle constituting of 42 %. Limousin Bulls breeds and Aberdeen Angus breeds created 21 % and 79 % out of that are owned by the breeder. The best average of hot carcass weight (HCW) was 399kg at Aberdeen Angus breed. The value of the carcass at Limousin bulls was 8 % lower and the bulls of the Czech Pied cattle was more than 20 % lower. The slaughter bulls were sold at an average age of 23 months and HCW 344 kg in 2013, in 2014 at the average age of 24 months and HCW 379 kg, in 2015 at the average age of 22 months and HCW 330 kg. The highest variability was recorded in the year 2015 with a value of 34,63 % and the lowest in 2013 with 8,80 %.
During the time period the highest cost entry has not changed. Just the share was different. The feed entry share was at 61,7 % in 2013, at 68,89 % in 2014 and at 52,30 % in 2015. 95,7 % of the total cost was assigned to the own feeding. The expenses in 2013 were 912 919 CZK, in 2014 dropped to 845 368 CZK and in 2015 increased to 1 213 190 CZK. The cost of one feeding day per cattle in 2013 was 28,10 CZK, in 2014 decreased to 26,02 CZK and in 2015 increased to 37,35 CZK.
The revenues were affected by the sale of cattle for slaughter. In 2013 was sold 21 pieces of cattle for a total amount of 545 040 CZK, in 2014 was sold 32 pieces of bulls in the total value of 977 643 CZK and in 2015 36 pieces of bulls in the total amount of 867 885,60 CZK. The sales of slaughter units in the total amount of revenue in 2013 did the share of 68,61 %, in 2014 increased to 72,25 % and in 2015 decreased to 59,20 %. In 2015 was the receipt share from slaughter bulls of 30 % based on the sale of alive bulls to Austria. Total revenues in 2013 were 823 517 CZK, in 2014 increased by 39 % to 1 353 080 CZK and in 2015 increased by 7 % to 1 466 062 CZK.
The Profit was calculated in 2013 as a loss in the value of 89 402 CZK. In the subsequent years there was a profit. In 2014 profit in the amount of 507 712 CZK and in 2015 the profit decreased to 252 872 CZK. The profit ratio in 2013 amounted to a negative value - 10 %, in 2014 increased to 60 % and in 2015 dropped to 21 %.

Effect of internal factors on milk production and quality
Šťásek, Jan ; Toušová, Renata (advisor) ; Jan, Jan (referee)
The aim of this thesis was to monitor and evaluate the impact of internal factors on the production and quality of milk in a herd of montbeliarde cattle. The hypothesis was that worse results of reproduction adversely affect milk production. Data collection took place on a farm Osičky agricultural company Agrodružstvo Lhota pod Libčany for the period from 1.1.2010 to 31.12.2015. The file was obtained 1 849 standard lactations completed in this period. The source of data for evaluation of milk production, milk quality and reproductive performance of cows were cards, program Farmsoft from Farmtec used to herd management and output data from the inspections carried out by the utility Chovservis Inc. residing in Hradec Kralove.
A statistically highly significant difference (P<0,01) between the first and all other amounts lactation in milk, fat and protein kg per lactation and fat in % and between 1st and 5th and more lactations in % protein. Was a positive effect of length of service period and the length of the intervening period the quantity of milk, fat and protein in kg per lactation at significance level P<0,001 and the negative influence of the length meantime to protein content in % (P<0,001). He was also found at least P<0,001 positive effect on lactation length produced kilograms of milk, fat and protein. Fat and protein also positively influenced the amount of milked milk (P<0,001). It was statistically insignificant effect on the incidence of mastitis production and milk quality (P>0,05), based on correlations may have an adverse effect on the percentage of fat and protein at a higher incidence of mastitis expected. The influence of the proportion of blood Montbeliarde breed was statistically proven only on the amount of milk and protein in kg per lactation, but still pure-bred animals came out the best in all of the indicators except for milk production fat percentage.
From comparison of the calving showed that his herd performance increases every year, the quality of milk as the fat content in % but conversely decreases. For the month of calving has been shown to influence the percentage of fat and protein at a significance level of P<0,001, the quantity of milked milk (P<0,01) and the amount of produced protein in kg per lactation (P<0,05).
The hypothesis that impaired reproduction results negatively affecting milk production has not been confirmed. It was found to influence reproduction indicators on production and quality of milk, but this influence in a positive direction. The negative effect was demonstrated only for the length of the interim influence on protein content in %.
Overall, the level of flock assessed as very good, but there are many indicators of production and reproduction that is necessary with respect to the potential of improving the breed.

Influence of robotic milking on milk production and quality
Houšková, Veronika ; Toušová, Renata (advisor) ; Jan, Jan (referee)
The object of this thesis was to assess the influence of robotic milking machines on the production and quality of milk in a herdof Czech Mottled Simmental cattle at a family farm Suchý during the period from January 2014 to December 2015.
The hypothesis: Robotic milking worsensre productive performance of cows and aggravates diseases of the limbs.
When evaluating the milk yield and reproductive performance of dairy cows in individual years, the data necesery was obtained from the control documentation of processed during regular yield assessments, carried out by Natural spol. s.r.o and the data selected from Analysis of a Herd Registered in a Herd-book of Czech Mottled Simmental Cattle, drawn up by the Czech-Moravian Breeders Association a.s. The statistical evaluation was processed and analysed by using Microsoft Office Excel and a statistical programme SAS 9.3 (SAS/STAT 9.3, 2011).
In respekt of the influence of order of lactation, it was found that some indicator shave a strong influence. As fortheherd A as well as herd B, a positive correlation between the sequence of lactation and milk production in kg (r= 0,123 herd A, r= 0,289 herd B; at a significance level of p<0.001). In herd A the milk production was higher than in the second and subsequent lactations by 1,165 kg compared with the first lactation (6,835kg). In a herd milked by a robot the production of milk was significantly higher than in the second lactation, and that by 2,221kg (7,285kg). Another positive correlation was found between thes equence of lactation and the number of somatic cells (r= 0.556 herd A, and r= 0,669 herd B and on the level of signifikance of p<0,001). In the originál herd quantities of somatic cells were measure dagainst the second and higher lactation, and that 388 x 1000/ ml. The same result has beenals of fortheherd B with a milking robot. The higher number of somatic cells was retraced in the second and higher lactation (282 x 1000/ ml); that means a lower value by 138 x 1000/ ml in comparison to the first lactation. When viewing the influence of the order of lactation on qualitative indicators, negative correlation wasestablished only in respekt of fat and lactose content.
After the evaluation of influence of the number of lactation days, a positive influence was found on the production of milk in kg (r= 0,923 herd A, and r= 0,885 herd B at a signifikance level of p<0.001). In both herdst hehighest performance wase stablishe dat the peak of lactation (24,6 kg forherd A and 27,19, kg forherd B). It was alsonoted that thereis a positive effect of lactation days on the protein content in milk (r= 0,253 forherd A and r= 0,100 forherd B on a level of signifikance of p<0.001). The highest percentage of protein was present in the originál herd A (3,385%) as well as in the robotisedherd B (3,365%) in the first lactationphase 1- 40 days. Contrariwise, number of lactation days has a negative effect on the kontent of fat, lactose and somatic cells in the milk.
In this thesis reproductive indicators were also evaluated. In robotised herd the repre found better values in the interim period, service period and during gestation period of cows after 1st insemination. In contrast with stalls with tandem milking, better results of conceiving of heifers after 1st insemination were achieved as well as conceiving of heifer after all inseminations, the insemination index and the percentage of conceptions of cows after all inseminations.
The above results indicate that the hypothesis cannot be fully confirmed or refuted. That part of the hypothesis, which assumes that robotic milking worsens the health condition of the limbscan be confirmed. But the second part of the hypothesis, deterioration of reproductive performance cannot be confirmed. For most of the reproductive performance indicators of there was signifiant improvement in milking using the robot.

Monitoring internal factors on milk production and quality
Králová, Alena ; Toušová, Renata (advisor) ; Jan, Jan (referee)
The aim of this thesis was to evaluate the influence of internal influences on the production and milk quality on selected farm. Data for preparation of this thesis were obtained on a farm in Skalica in Frydek-Mistek belonging to the joint-stock company Beskyd Agro. Data used in this thesis were evaluated for two years (1.10.2013-30.9.2014, 1.10.2014-30.9.2015). Data were analyzed and statistically processed using Microsoft Excel software. Evaluation of milk production and reproductive performance were based on the results obtained from regular inspections. For milk yield parameters were evaluated milk yield (kg) Fat (%, kg) Protein (%, kg) of milk somatic cell count (SB) depending upon reproduction and lactation. Evaluated herd were divided into 2 groups: I. lactation, II. lactation and the next lactation. Hypothesis: Worsening indicators of reproduction have negative impact on the level of milk production and its components.
The final evaluation of the data were used, comprising 280 cows of Holstein cattle, which were included in monitoring performance period. The results show that the average length of the interim period was around 416 days in average.Milk yield was 10,062 kg of milk with fat contents of 4.21%, 3.37% proportion of protein and somatic cell count 477.75 thousand / ml. The difference in milk yield of heifers at first (9 326.38 kg) and second lactation (9 901.47 kg) reached 575.09 kg. Maximum milk production was achieved on 4th lactation, when milk yield reached 10 432.16 kg per lactation.
Positive effect was demonstrated between the % fat content and protein content in%. With the increase in the% fat content, and increased protein content in%. The highest value of the average amount of fat has been statistically proven at 5th lactation and values of 4.18%. For proteins the highest number was reached during the lactation no. 6 with values of 3.40%.
The best values were obtained in lactation number 4., where the rate reached the following parameters:
milk yield per lactation 10,432, 16 kg
daily milk yield: 34.20 kg
fat: 4.08%
protein: 3.35%.
It was determined that the amount of milk yield per lactation in kg was positively affected by the value of the daily milk yield in kg, with the value (r = 1st) verified at a significance level (P <0.001). Increased milk yield per lactation kg should result in an increase daily milk yield. The negative impact was demonstrated in representating % fat content of milk (r = -0.653) and protein (r = -0.442) at the level of significance (P <0.001). Increased milk yield per lactation in kg was negatively effected and reduced the component of fat and protein. Milk yield per lactation had a positive effect on service period. Positive effect on milk yield heifers was demonstrated in service period and with a positive value (r = 0.327) with evidential significance level (P <0.05). Effect of milk yield per lactation, age at first calving was not demonstrated.
Effect of daily milk yield in kg of milk, had a negative effect on the proportion of components in % fat (r = -0.653) and protein (r = -0.442). Conclusive came to the level of significance (P <0.001). Increase in daily milk yield will reduce the content of components of protein and fat milk. The positive impact of the daily milk yield was demonstrated in connection with the service period (r = 0.247) at a level of significance (P <0.05). Increasing daily milk yield, this will extend the service period.
From the resulting data, negative effect on lactation representation% protein content (r = -0.288) and fat (r = -0.052) with evidential significance level (P <0.001) was determined . Effect of lactation on milk yield per lactation, daily milk yield, calving interval and service period has been shown.
Daily milk yield in kg of milk is affected by the amount of milk yield per lactation in kg (r = 1). Conclusive came to the level of significance (P <0.001). Increased milk yield per lactation is proportional to increase of daily milk yield. Milk yield per lactation negatively affected% of fat content (r = -0.187) and% representation of protein (r = -0, 208). Conclusive came to the level of significance (P <0.05). Increasing milk yield per lactation kg reduces% fat and protein. The relationship between milk yield per lactation in kg, service period, and interim periods has not been demonstrated.
Effect of daily milk yield in kg, had a negative effect on the% fat content (r = -0, 187) and protein (r = -0.208) with evidential significance level (P <0.05). Reduced% protein content and milk fat is a result of increased daily milk yield in kg. Effect of daily milk yield on service period and the interim has not been demonstrated.
Fat content in% and the protein in% (r = 0.603) were demonstrated at a level of significance (P <0.001). Increased if the% fat content, increased the% protein content.
The positive effect was demonstrated between service period and interim periods (r = 0.266) with evidential significance level (P <0.001). The longer the period of service increases the length meantime.
It was confirmed that with increasing lactation milk yield as per lactation, daily milk yield and milk components content.

The effect of reproduction traits on milk production and quality
Novotná, Markéta ; Toušová, Renata (advisor) ; Jan, Jan (referee)
The aim of this diploma thesis is to evaluate fertility indicators and milk production on a selected farm. I have anticipated lower milk utility and less frequent pregnancy rate during summer time in comparison to other seasons.
The selected stable in Bílý Újezd is a part of ZEAS Podorlicko a.s. corporation. In this stable the dairy cattle of Holstein breed was studied. The breed was mixed with ayshir and red holstein, not exceeding 15% of blood mixture. Milk utility of 511 milkers was evaluated from October 1, 2013 to October 31, 2015. The data was gained from Milk Profi Data program and then statistically evaluated in SAS version 9.3. The analysis focused on the influence of lactation sequence, year influence, season influence and the influence of lactation period on daily milk production, percentage ingredient volume and the amount of somatic cells in milk.
The average count of lactations in a herd was 2.34 in the examined period and the average day of lactation was 169.32. A positive influence of lactation sequence on daily milk production was discovered (r = 0.056; P < 0.001). The highest daily milk production was detected within fourth lactation milkers (30.72 kg). Daily milk production was increasing year-on-year, the highest was in 2015 (32.09 kg). The influence of seasons on daily milk production was noticeable. Milkers had statistically the highest volumes of milk production in autumn (30.32 kg; P < 0.001). The lactation period had a negative influence on daily milk production (r = -0.548; P < 0.001). Till 60th day of lactation the daily volume of milk production was increasing, and then since 61st day till the end of lactation it was decreasing. The days of lactation had positive influence on fat content (r = 0.078; P < 0.001).
The influence of lactation sequence on a fat percentage could not be statistically proven. In 2013 the fat content was higher (3.84%) then in 2014 (3.64%). Compared to 2014, the fat content increased on 3.80% in 2015. The lowest fat content in milk was during summer (3.58%). In autumn the fat content reached 3.79% and it was the highest in winter (3.92%). The fat content decreased in spring, falling to 3.75%. A positive influence of lactation period on fat content was proven (r = 0.078; P < 0.001).
Any influence of lactation sequence on protein content was not statistically proven. The highest protein content was noted in 2013 (3.58%), then it decreased in 2014 on 3.52% and 3.48% in 2015. The highest protein content was reached in winter (3.62%). The protein content decresed in spring on 3.51% and the lowest level was in summer (3.38%). The protein content increased again in autumn reaching 3.60%. The influence of season was proven to be positive on lactation period and protein content (r = 0.451; P < 0.001).
A negative influence of lactation sequence on a lactose content was proven (r = -0.375 ; P < 0,001). A positive infuence in lactose content (r = 0.283; P < 0.001) was discovered throught seasons. The lowest lactose content was measured in winter (4.74%), it rose in spring reaching to 4.79% and in summer to 4.80%. The highest lactose content was in autumn (4.84%). Also a negative influcence of lactation period on lactose content was proven (r = -0.221; P < 0.001).
A positive influence of lactation sequence on the amount of somatic cells in ths/mL (r = 0.197; P < 0.001) was discovered. On the contrary the seasons had negative influence on the amount of somatic cells in ths/mL (r = -0.060; P < 0.001). A statistically noticeable difference was revealed between the amount of somatic cells measured in autumn (807.92 ths/mL) and in winter (968.58 ths/mL). The influence of lactation period on the amount of somatic cells was not proven.
Altogether 544 milkers were assesed for reproduction capability in the period from October 1, 2012 to October 31, 2015. The data was obtained from WebSkot program and statistically evaluated by SAS program version 9.3. The analysis focused on the influence of lactation sequence, insemination sequence and the month of insemination pregnancy rates, servis period and the interval of insemination.
The influence of lactation and the insemination sequence on pregnancy rate could not be proven. The analysis showed that the pregnancy rate was lower in August (23.69%) than in December (46.50%).
The influence of insemination on servis period could not be proven. A positive influence of insemination sequence on servis period was discovered (r = 0.802; P < 0.001). The influence of the month of the insemination on servis period was not proven as well.
The influence of lactation sequence nor insemination sequence on insemination interval was not proven. It was discovered that the insemination interval was shorter in December (70.01 days) then in July (90.15 days; P < 0.005).
Hypothesis, which presupposed lower milk utility in summer in comarison to winter was disproved. Hypothesis about lower pregnacy rates in summer months was proved.

Performance recording in Charollais herd in organic farming
Rechnerová, Martina ; Toušová, Renata (advisor) ; Jan, Jan (referee)
The goal of the thesis was an evaluation of the growth rate of calfs since their birth up until to the 365th day of their life, and reproductive performance in a selected group of the Charolais cattle. Data was gathered from the results of a utility-control carried out by a selected farm (UFARM spol. s.r.o.) from 2009 to 2014. This farm has been operating in an ecological system since 2007. A total of 806 calves has been evaluated. Several factors were selected (sex, lifespan, breed frequency, order of fertilizations, development of delivery, breeding technique, year and month of birth of the calves) that were supposed to prove the influence on the calves' growth rate. From the reproductive factors the meantime, during which was the year's development observed and breeding technique were selected.
Statistical programme SAS 9.3, procedures MEANS, UNIVARIATE, REG, CORR, STEPWISE and MIXED were used to obtain results.
From the results of statistical evaluation, it was possible to prove, that delivery development is affected by weight on the level of significance P < 0,001. The insignificant influence on the growth until the age of 120 days (P < 0,05), weight in 210 days (P < 0,05) and growth until the age of 210 days (P < 0,05) was interesting as well. After observing the influence of the fertilization order on the calf's growth developement, it is fair to state that the order of fertilization has a strong influence only on the calf's weight during delivery (P < 0,001). Birth weight varied strongly in all of the listed fertilization orders (1, 2, 3, 4, 5, 6, 7, 8 and higher) on the level of significance. Calfs born to a heifers weighed the least on average (43, 03 kg). On the contrary, the highest average weight of a newborn calves was observed by mothers that gave fourth (45, 68 kg), eighth and higher fertilization (45,69 kg).
The influence of sexual dimorphism on the development of all growth factors of calves is apparent from the results (weight and growth since birth to the 365th day of life) and benefits the males (bulls) with the level of sigficance P < 0,001. One year's influece has been proven on almost all of the calves' growth factors (weight and growth since birth to the age of 365 days) on the significance level P < 0,001. Further observation showed that year 2009 had no influence on weight in 120 days and growth up until 120 days. Years 2012 and 2013 had no influence on calves' weight at 365 days, as well as on growth at 365 days.
In 2014, on average highest, statistically proven values in all the monitored parameters. Furthermore, influence of the month, in which the calf was born, has been proven to have influence on weight at 210 days, growth at 210 days, growth (up to day 365) and weight at 365 days (P < 0,05). During further observation, statistically relevant differences depending on the month of birth have been recorded only in growth up to 210 days and in weight on day 365 (P < 0,05). The heaviest calves at the age of 365 were those born in March and, on the other hand, those born in April weighed the least. The chosen breeding technique influeced particularly the growth since birth (P < 0,01), weight at 210 days (P < 0,01) and growth until 210 days (P < 0,05). Less influenced is the weight at 120 days and growth up to 120 days of age. Except for the birth weight, the values of growth coefficients were higher in natural breeding. Analysis of results proved multiparity to be influetial on the calves' growth rate. Litter size influenced foremost the birth weight, weight at 120 and 210 days, and growth up to 120 days of age and 210 days of age on the significance level P < 0,01. A statistically less significant influence of the (litter size / breeding frequency) on the growth since birth and weight at 365 days was observed. All of the growth coefficients were higher in one offspring
(only child/calf).
The selected factors (calf's year of birth and fertilization method) had a statistically significant influence on the postpartum anestrus (P < 0,001). The duration of postpartum interval varied in all monitored years (2009/2014) on the significance level P < 0,01.
On average, the highest number of days had the postpartum interval in 2012 (379,60) and the least number of days had the 2009 postpartum interval (282,50). postpartum inverval duration is proven to be influenced by the breeding technique on the significance level P < 0,01.
Only in 2009 and in inseminated cows did the average length of the postpartum interval not meet the requirements set by breeding objective of the charoalais cattle.

Analysis breeding of Holstein cattle
Matěnová, Lenka ; Toušová, Renata (advisor) ; Jan, Jan (referee)
The aim of bachelor´s thesis was to carry out the analysis of Holstein cattle farming in a selected farm. I carried out the analysis in Agricultural corporation Svobodné Company that farms in Hradec Králové region in the district town of Trutnov.
The company farms about 925 hectares of agricultural soil. Arable land is on 529 hectares and 400 hectares is for permanent grass cover. The main content of crop production is forage produce for livestock farming. Livestock farming is aimed at the red Holstein cattle farming. The herd was made by crossbreeding in 1996 from the Czech Straka. There are 270 milch cows in this company.
The first part is focuded on the theoretical interpretation of milch cow farming problems. I focused on the characteristics of breed, efficiency, reproduction, technology of milking and lairage, nutrition and feeding and the most common milch cow´s health problems. The monitored period was from October 2014 to September 2015. Data were derivated from the efficiency monitoring.
During the monitored period was closed up 253 lactations set by the norm. The efficiency was 8 677 kilograms of milk with 4,44 % of fat and 3,51 % of proteins. Heifer milked 7 630 kilograms with 4,81 % of fat and 3,56 % of proteins. The milking house is designed as 2 x 8 by the Farmatec Company, with twice a day milking. The average efficiency for connected milch cow was 24,4 kilograms, for contolled milch cow 26,5 kilograms of milk. The problem is the high value of the body cells and cloven hooves problems are connected to it. There is more than 10 % of milch cows where the limit has overcome one million of the body cells. High body cells are occured by the calved heifers as well that should be decreasing the other way around. These are not able to compensate mammary gland destruction. That is the reason of their efficiency decrease. In February cooperation with Eurofarm Company started to improve milch cows preparations and the hygiene before milking. There is a bacteriological screening for resistence to antibiotic once a year.
Another problem is reproduction results. Success rate in the process of calf pregnant was 29,7 %. The insemination interval was 73, intervening time 402 and service period 122 days. The intervening time length is suitable. It is necessary to realise that these cows are high utility milch cows these are suffer from the risk of NEB (negative energy bilance) in a few first weeks. That´s why they work into from the 60th day. In the end of the lactation period they milk over 25 kilograms. It is the reason for longer intervening time.
Heifers are worked into for the first time in 14 months.
Health state of the herd is at a high level quality. Calves mortalities is beeing kept below 2 % in the long term. There is a long time bad health state of cloven hooves by the milch cows. The most frequent diseases are ulcers and dermatitis. These diseases hurt cows and the pains influence the utility and the rutting symptoms in a negative way.

The influence of different diet on the hematological and biochemical parameters in rats
Hudíková, Tereza ; Fučíková, Alena (advisor) ; Jan, Jan (referee)
This thesis aims to investigate the relationship between increased protein dosage intake and selected haematological and biochemical markers. An experiment was designed using the Wistar laboratory rats of the male gander and similar age (born within +/- 5 days). These specimens were then divides into 3 groups with 10 specimens each. The age of the specimens at the beginning of the experiment was around 62 days. The first group was fed the standard corny mixture ad libitum, while the second group received 6 grams of the standard corny mixture and 10 grams of beef meat per day (thus reflecting the same amount of nitrous compounds as for the first group) and the last (third) group was fed ad libitum with homogenised beef meat. Before the diet was imposed on the three groups, blood samples were collected from all specimen from the lateral tail vein; after the diet was completed, blood samples were collected by in vivo heart puncture. All blood samples were subjected to haematological (using EDTA blood) and biochemical (using blood plasma) analysis. Overall, the following markers were measured: amount of erythrocytes, haematocrit level, haemoglobin level and Mean Corpuscular Volume (MCV) for the haematological analysis and triacylglycerol level, cholesterol level, amount of urea, amount of magnesium and the amount of iron for the biochemical analysis. Dietary induced significant changes were observed for the following markers: number of erythrocytes, levels of haemoglobin and MCV from the haematological analysis and cholesterol levels, amount of magnesium and amount of iron from the biochemical analysis; therefore showing that altered diet can have affect haematological and biochemical blood markers.

Solving of the logistic problem using Lean management, System Approach and Operation Research methods
Frajtová, Veronika ; Brožová, Helena (advisor) ; Jan, Jan (referee)
The master thesis is focused on problems within the Logistics System of an unnamed company. The theoretical part introduces Systemic Approach problem solving, as well as the methodology of Six Sigma and Lean Management and its analytical tools, and finally with Logistics as the section of Operations Research. The practical part contains a brief introduction to the company profile, the use of Systemic Approach and methods of Six Sigma and Lean. Procedures of these methods are compared afterwards. Within the System Approach is also done the analysis using Operational Research Method - the Queuing System. Based on the analysis is determined a model that expresses the best use of the system.
