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.

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.

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). In 2019, the lean meat content at farm A was 0.3% lower than at farm B (59.1, resp. 59.4%; p < 0,5). In 2020, the lean meat contentat farm A and at farm B was the same 58,5%.

The aim of this study was analysis of growth parameters in piglets. 40 first litters of sows gave data for study. Number of piglets, birth weight, weight at 14 days and weight at weaning were analysed with mathematics and statistics method and evaluated dependence of growth parameters of piglets. Especially influence of birth weight and sex on weight at 14 days and weaning and on average daily gain. Dependence of productive index of piglets and reproductive index of sows was studied. Results poited to influence of birth weight to weight at 14 days, weaning weight and average daily gain. With higher birth weight was higher weight weight at 14 days and weaning and higher average daily gain. Reproductive index and productive index shows to correlation between number of piglets and litter weight.

Perničková, Andrea
The objective of this study was to monitor the growing intensity of the bulls of Czech Fleckvieh with subsequent evaluation of the quality of the carcass in a selected company in the Vysočina. There have been monitoring in the years 2011-2014 these indicators and inter-annual results: bulls housed an average of 293 pieces, increases amounted to an average of 35580,76 kilograms in total, concentrated feed consumption averaged 2,66 kg per ks.den-1, concentrated feed consumption was of average 94667 kg total, average growth per day feeding 0,99 kg, feed consumption per kg of growth reached an average of 2,89 kg, an average of 94 bulls were sent to slaughter, with a total weight of 58,987 kg and the average slaughter weight amounted to 633,2 kg. Finally, evaluate the effect weight was 266 bulls for carcass quality, the average slaughter weight amounted to 715,4 kg. As an indicator was chosen carcase weight, which amounted an average of 401,9 kg. Furthermore, the average daily gain these monitored bulls amounted 0,985 kg, and the average age at slaughter was 23 months. Another indicator of the level of conformation, which assigned a point value system amounted 3,42. The degree of fat cover, which in the allotted scoring average value amounted 2,12. Average entry into the class SEUROP these bulls was U2. To evaluate the influence of slaughter weight of bulls on selected indicators of meat production was observed positive effect of increasing slaughter weight of bulls for carcass weight and conformation level carcasses. Fat cover of carcases different slaughter weights were not negatively affected. An interesting finding was a higher average daily gain of bulls slaughtered at higher weights. This indicates good genetic potential of animals on its suitability for fattening to slaughter weight higher, while achieving higher quality carcass (SEUROP favorable classification system and the higher financial profit for slaughter animal). In the company will still need to optimize ration, mainly to enhance the quality roughage feed.

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.
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.
