Vliv modernizace stáje na produkční ukazatele v chovu kachen
FULÍN, Ondřej
The subject of the thesis was the analysis of performance characteristics of the broiler Peking duck hybrid Cherry Valley SM3 in the Smilkov a.s. enterprise in the modernized barn in comparison with the data obtained before the modernization of the barn (original barn). Practical monitoring was carried out in the modernised barn, in which a controlled microclimate was applied. Each round was stocked with a quantity of 3 200 ducks. The weighting was always 1 % of the total stacked turn, i.e. 32 ducks. During the period under review, data were collected from 7 turnovers at weekly intervals starting from stacking, i.e., day 1 of age to day 42 of age of the ducks. From the 3rd week of age onwards, the live weight of ducks was lower in the upgraded barn. It was found that at 42 days of age, the live weight in the original barn was 3 596 g, whereas, in the upgraded barn, the live weight decreased to 3 335 g (difference of 261 g). Thus, the data obtained in the modernised barn also showed a lower average daily gain over the period under study (77.8 g), which started to lag behind the average daily gain from the original barn (82.6 g) during fattening, as was the case for the live weight from 3 weeks of age. The difference in average daily gain over the period considered was 4.6 g. The reduction in live weight and average daily gain was related to a reduction in compound feed consumption. During the period under review, the consumption of compound feed decreased from 165.1 t (original barn) to 152.0 t (modernised barn). With lower compound feed consumption, feed conversion improved slightly, decreasing from 2,30 kg/1 kg gain in the original barn to 2,28 kg/ 1 kg gain in the modernised barn. Mortality increased in the modernised barn from 2.87 % to 3.27 % (a difference of 0.40 %). On the basis of the analysis of the mortality data, it can be concluded that the higher mortality was probably due to insufficient cleaning of the sheds or failure to comply with all the disinfection principles when preparing the shed for the following turn.

Analýza užitkových parametrů prasat ve vybraném chovu
Klváček, Pavel
The thesis focuses on analyzing the production and reproduction parameters in pig breeding in Ochoz u Konice. The theoretical part of the thesis includes research on pig reproductive indicators such as fertility and lactation, followed by production indicators, which include growth, feed efficiency, and slaughter value. Furthermore, the issues related to rearing of gilts and their inclusion in breeding are described. The thesis also briefly describes the reproductive cycle of sows, from insemination to piglet rearing. Subsequently, the methodology for monitoring pig performance in the Czech Republic is described. The last part of the literary review characterizes the individual genotypes of Topigs Norsvin pigs. The practical part of the thesis presents the material and methodology of testing. Reproductive and production utility were tested among Topigs Norsvin pig genotypes. The A-line, AxZ, and TN60 genotypes were studied. The influence of parity on reproductive utility and the influence of sex on production utility were also observed. The monitored reproductive parameters included the number of all piglets, live and kept piglets in the litter, as well as the number of stillborn and dead piglets and the percentage of stillborn and dead piglets in the litter. The average daily gain during weaning, pre-fattening, and fattening of pigs was also determined. The results of reproduction indicated that the highest number of all, live, and kept piglets was achieved by the TN60 sow, while the A-line sow had the lowest number. Regarding parity, it was found that the number of all, live, and kept piglets increased with increasing parity of sows, with the lowest number at the first parity and the highest at the fifth parity. The results of production showed that the highest average daily gain was in TN60 pigs, and the lowest was in A-line pigs. In terms of sex, boars achieved higher average daily gain than gilts in all tested genotypes. The TN60 pigs achieved better results in both reproductive and production utility than A-line pigs, confirming the positive operation of hybridization.

Ekonomické zhodnocení intenzivního výkrmu býků masných plemen skotu
Kosová, Michaela
The diploma thesis deals with the fattening of slaughter bulls of the Aberdeen Angus, Charolais and Limousin breeds from the weight category to slaughter weight. The main goal of this work was to economically evaluate the effectiveness of intensive fattening of beef bulls. A total of 366 animals were monitored in two feedlots. In the practical part, the animals were weighed in different stages of fattening, at the age of 8 and 14 months, and on the basis of these data, an analysis of the influence of the breed was carried out and subsequently the economy of fattening was evaluated. Growth was assessed by average gains for individual breeds and farms. The results show that the breed has a significant effect on the intensity of growth. The results were statistically significantly highest in the Aberdeen Angus breed in the pre-weaning period (1.12 kg/day), but after moving to a barn with intensive fattening, the highest growth intensity was achieved in the Charolais breed (1.61 kg/day). Weight increased linearly with age in all bulls, the highest differences were observed in the Aberdeen Angus and Limousin breeds. After the 1st and 2nd weigh-ins, representatives of the Aberdeen Angus breed (330.02 kg, respectively 579.57 kg) achieved the highest weights, while representatives of the limousine reached the lowest (302.24 kg, respectively 555.27 kg). The absolute highest average daily gains were achieved by bulls of the Charolais breed, in 160 days of intensive fattening, the absolute gain was 255.3 kg. Despite the lowest age, the bulls had the highest weight at the end of fattening, thanks to the high intensity of growth. The highest calculated profit was achieved on Farm A with the Charolais breed (CZK 8,838.37) and on Farm B with the limousine breed (CZK 2,645.6). The costs per feeding day ranged from 89 to 91 CZK.

FULÍN, Ondřej
The aim of the bachelor thesis was to perform practical monitoring of production indicators of broiler hybrid Cherry Valley SM3 in the Smilkov farm Ltd. The study was carried out in two breeds (Smilkov and Kouty) with different fattening technology for the period of 1 year. The weighing always included 1 % of the total number of ducks of the monitored batch, i.e., 32 ducks. The results were obtained from 14 batches (7 batches from each barn). The highest live weight was achieved in the Smilkov breed, with an average of 3.52 kg/pcs, while the Kouty breed achieved an average weight of 3.45 kg/pcs. The Smilkov breed also achieved a better average daily gain, which was 83.3 g/head/day, the Kouty breed had a lower average daily gain of 81.5 g/head/day. The Kouty stable, which has a controlled microclimate, showed better results in mortality rate and feed consumption. The average mortality rate was 1.64 % and 153.3 t of complete feed mixture were fed during the period under review. The average mortality rate in the Smilkov farm was 2.87 % and 165.1 t complete feed mixture was consumed, a difference of 11.8 t of feed between the farms. The feed conversion ratio (amount of feed needed per 1 kg of gain) in the Kouty farm was 2.2 kg/1 kg of gain, while in the Smilkov farm the conversion was found to be 2.3 kg/1 kg of gain.

BEDNÁŘOVÁ, Kristýna
The aim of the diploma thesis was to analyse reproductive and productive performance of sows at two sow farms evaluated 432 litters at farm A and 321 litters at farm B. Better reproduction results were achieved at farm A. In 2019 the difference between farm A and Farm B was 2.3 pcs in number of all born piglets (16.3, resp. 14.0 pcs; p < 0.05), 2.5 pcs in live-born piglets (14.7, resp. 12.2 pcs; p < 0.05) and 1.7 pcs in weaned piglets (12.9, resp. 11.2 pcs; p < 0.05). In 2020, the difference between farm A and farm B was in the number of all born piglets 2.6 pieces (17.2, resp. 14.6 pcs; p < 0.05), live-born piglets also 2.6 pcs (14.2 resp. 12.0 pcs; p < 0.05). The farrowing interval was 149,3 days in 2019 and 151,2 days in 2020 at farm A. The farrowing interval was 161,8 days in 2019 and 159,4 days in 2020 at farm B. The number of teats was monitored at 6 584 sows at farm A and 4 210 of sows at farm B. The total number of 16 teats was at 12.8% sows at farm A and 18.2% of sows at farm B. Productive performance in the field test was evaluated at 304 gilts (farm A) and in 394 gilts (farm B). In 2019, the average daily gain in field test at farm A was 36.5 g higher than at farm B (998.1, resp. 961.6 g; p < 0.05). In 2020, the average daily gain in field test at farm A was 46.5 g higher than at farm B (985.7, resp. 939.2 g; p < 0.05).In 2019, the average backfat thickness at farm A was 0.1 mm higher than at farm B (6.6, resp. 6.5 mm). In 2020, the average backfat thickness at farm A was 0.1 mm lower than at farm B (6.8, resp. 6.9 mm).

BÍNOVÁ, Hana
The aim of this thesis was the evaluation of the meat performance of Salers beef-cattle bred in two private farms under different climatic conditions (altitude) one farm was situated 450 m above sea level, the other 750850 m above sea level. The evaluation included 36 purebred breeding-cows and 87 calves in the first farm and 38 purebred breeding-cows and 64 calves in the second farm. The observation was carried out in the period 20142016. The average age of the cows bred in the lower altitude farm was 8.5 years, 6.3 years in the second farm. The average calving interval of cows in the first farm was 392.10 days, calving interval of cows from the mountain area farm was 492.60 days. The first calving of cows was reached in three years on both farms (2.8 and 2.9 years respectively). The calves born on the farm in the higher altitude had higher birth weight and daily gains to the age of 210 days. The difference of the average birth weight between the groups was 5.7 kg, 10.94 kg at the age of 120 days, and 25.63 kg at the age of 210 days. When comparing live weight, the calves from natural breeding had better results than the calves from artificial insemination. The study proved an excellent milking capacity of Salers cows and therefore a good growth ability of the calves even under mountain condition of Šumava.

ŠEBELKA, Štěpán
The aim of this thesis was to analyze the results of the Aberdeen Angus meet herd breeding in an ecological farming with the welfare relationship to the animals and at the same time to compare the efficiency after the system change of the farming at the farm Angus, Rančice, owned by Milan Šebelka. The research was done in the period of years 2005 ? 2012. The survey range includes 80 heads of thorough-bred cows as well as 266 heads of Aberdeen Angus calves born in the tracked period. The number of births and calving interval was dated by the cows. By the calves we noted the live weight and average daily gain in the growth process. The population of the calves was then sorted our by year of the birth, sex and by the way of farming. The data entries were elaborated in the MICROSOFT EXCEL and evaluated in STATISTICA. The cows had the calving interval of the period often from 351 to 380 days. In the herd with the most cows occurred at 3rd calf length interval. By the monitored number of calves no matter of the sex was noted the lowest live weight by the birth in transitional period (37.97 kg). The group of calves born in organic farming reached the highest average weight by the birth, in 120 days as well as in 210 days (38.88 kg, 190.91 kg, 307.81 kg). The lowest average weight in 120 days was noticed in transition period (176.93 kg), in 210 day in transition period again (271,56 kg). The best growth ability from the birth to 120 days was by the group of calves born in organic farming (heifers ? 1.177 kg, bulls ? 1.353 kg) compared to the lowest result in transitional period (heifers ? 1.091 kg, bulls ? 1.215 kg). The average daily gain from 120 till 210 days reached its minimum transitional period (heifers ? 1.082 kg, bulls ? 1.233 kg), the maximum numbers were noted in organic farming (heifers ? 1.253 kg, bulls ? 1.343 kg). The growth intensity from the birth till 210 days its minimum transitional period (heifers ? 1.074 kg, bulls ? 1.154 kg), the maximum numbers were noted in organic farming (heifers ? 1.209 kg, bulls ? 1.347 kg). In the ecological agriculture system was noted statistical better efficiency results (live weight, growth intensity) compared to conventional agriculture system.

Analysis of beef cattle herd
BRŮHA, Karel
The purpose of this thesis was to evaluate the level of performance of Aberdeen Angus beef cattle breed bred in Less-favoured areas in southern Bohemia. This evaluation was carried out on Mr. Lepša?s farm in the years 2010 and 2011. 74 basic herd cows and 108 purebred calves born during this period were selected for this purpose. The date of birth, number of births, age at first calving and the average time interval between calving were checked on cows and the date of birth, the weight at birth and the weight in the age of 120 and 210 days were checked on calves. Average daily increments in the interval from birth to 120 days of age, from 120 to 210 days of age and from the day of birth to 210 days were calculated. The group of calves was sorted out by following parameters. Year of birth; sex and year of birth; month of birth; order of calving of the mother. Microsoft Excel was used for processing the statistic data. Basic statistical characteristics for the monitored parameters were calculated and differences between groups were verified by single-factor analysis of variance (F-test) and paired t-tests for the corresponding levels of significance. Breeding cows were evaluated by age and number of births. Cows with 1 (23%) or 2 (17.6%) births are represented in the largest number in the herd including even the cows with 15 births. Cows at first calving reached an average age of 813 days and average length of the interval between calving was 393 days. Calves regardless of sex reached the average birth weight of 33.72 kg in the year 2010, 33.31 kg in 2011, in 120 days of age the average live weight reached 207.95 kg in 2010, 202.94 kg in 2011 and calves in 210 days of age reached an average weight of 309.61 kg in 2010 and in 2011 306.09 kg. Average daily gain of calves from birth to 120 days reached 1451 g in 2010, 1.413 g in 2011, between 120 and 210 days of age the average daily gain was 1413 g in 2010, 1169 in 2011 and in the period from birth to 210 days of age it was 1314 g in 2010 and 1299 g in 2011. Analysis of breeding from economic perspective by comparing revenues (including subventions) and expenditures in each year resulted in findings that the breeding is moderately profitable and it follows that without subventions which constitute an important part of the revenue would be difficult to realize this breeding.

TOMKOVÁ, Kateřina
The aim of this diploma work was to analyse the results of the Aberdeen Angus meet oxherd breeding in an ecological farming with the welfare relationship to the animals and at the same time to compare the efficiency after the system change of the farming at the farm Angus, Rančice, owned by Šebelka. The research was done in the period of years 2006 ? 2011. The survey range includes 65 heads of thorough-bred cows as well as 204 heads of Aberdeen Angus calves born in the tracked period. The number of births, the birth process, and the age before lay out and related reasons were recorded by the cows. By the calves we noted the live mass and average daily gain in the growth process. The range of the calves was then sorted our by year of the birth, gender, rank of the birth, by genitors and by the way of farming. The data entries were elaborated in the MICROSOFT EXCEL and evaluated in STATISTICA 7 CZ. The number of spontaneous birth without cowman assist equals 94,12%, only 4,41% of births required the necessary support. By the monitored number of calves no matter of the gender was noted the lowest and the highest live mass by the birth in the year 2007 (36,81 kg resp. 38,77 kg). The group of calves born in 2010 reached the highest average weight in 120 days as well as in 210 days (192,27 kg resp. 309,04 kg). The lowest average weight in 120 days was noticed in year 2009 (168,96 kg), in 210 day in 2008 (262,31 kg). The best growth ability from the birth to 120 days was by the group of calves born in 2010 (1,409 kg) compared to the lowest result in 2009 (1,099 kg). The average daily gain from 120 till 210 days reached its minimum in 2009 (1,171 kg), the maximum numbers were noted in 2010 (1,412 kg). The growth intensity from the birth till 210 days circulated in the range of 1,071 kg (2008) and 1,377 kg (2010). In the ecological agriculture system were noted statistical better efficiency results (live mass, growth intensity) compared to conventional agriculture system.
