The diploma thesis was processed in the cooperative farm Pooslaví Nová Ves on the basis of borrowed materials from zootechnicist Bc. Pavlíny Bendové. Were involved in monitoring for the year 2011 137 cows on 1st lactation and 165 cows on 2nd and higher lactation. In year 2012 132 cows on 1st lactation and 164 cows on 2nd and higher lactation. And in year 2013 it was 103 cows on 1st lactation and 175 cows on 2nd lactation. In diploma thesis at cows were evaluated these reproductive indicators: intercalving period, insemination interval, servis period and milk yield in kg. At heifers was evaluated age on 1st calving, insemination interval, servis period and milk yield in kg. At cows reproductive indicators was evaluated in individual years, lactation, inseminaton. At heifers it was in individual years, insemination, age on 1st insemination and their results were processed in program STATISTICA 12.0. In year 2011 at cows were detected this values: intercalving period 391,48 days, interval 72,39 days, servis period 135,90 days and milk yield 9094,75 kg milk. At cows on 1st lactation: age at 1st calving 793,07 days, insemination interval 78,18 days, servis period 128,88 days and milk yield 8466,69 kg milk. In year 2012 in whole herd of cows monitored were detected this values: intercalving period 405,03 days, insemination interval 73,29 days, servis period 135,94 days and milk yield 9522,63 kg milk. At cows on 1st lactation: age at 1st calving 780,96 days, insemination interval 72,51 days, servis period 125,78 days and milk yield 9126,15 kg milk. In year 2013 in whole herd were detected this values: intercalving period 404,88 days, insemination interval 78,94 days, servis period 138,46 days and milk yield 9941,66 kg milk. At cows in 1st lactation: age at 1st calving 792,57 days, insemination interval 80,45 days, servis period 140,24 days and milk yield 9545,19 kg milk.

Thesis has been focused on the analysis of selected factors affecting the length of gestation in cattle, Holstein breed. Pregnancy duration was considerably influenced by the month of conception. Gestation duration was also affected by alive and dead calf, parity, sex of calves and twins. In conclusion, results suggest that pregnancy of cows may be influenced by many factors.

The theoretical part of the thesis on "Evaluation of semen quality selected breeds of dogs", provides a brief summary of available information obtained from literature dealing with dogs reproduction, anatomy male genital tract of the dog and basic laboratory techniques of animal semen analyzes. Practical work was focused on evaluating quantitative and qualitative parameters of ejaculate different breeds of dogs from the kennel Bohemia Alké. Was investigated primarily affect the order of collection, ages, body frame, time of day and length of the sampling collection itself on ejaculate volume, activity concentration, total sperm count and percentage of occurrence patomorfologických defects. Subscriptions ejaculate, macroscopic and microscopic evaluation was conducted in field conditions in the home where the dogs lived. To evaluate the percentage of damaged sperm pathomorphological were made morphological coatings, which were transported to the laboratory department reproduction of farm animals and the Institute of Animal Breeding, Faculty of Agronomy, Mendel University in Brno.

The aim was to evaluate the reproductive performance of the dairy herd. Data were obtained on the farm ZZN Strakonice center Sousedovice from cows culled during 2015. The center treats an average of 250 cows that are kept free of manure and farm milked at four milking robots Lely - Astronaut. The most important reproduction traits were summarized and subsequently statistically processed. Monitored were fertility parameters, milk yield and lifetime production, which were derived from a zootechnical records and monthly reports from milk recording system on 100 dairy cows. With increasing milk yields were deteriorating reproduction parameters such as artificial insemination index, insemination interval and number of days open. For the entire group of cows was monitored milk productivity and reproduction parameters related to parity. The average milk yield in the selected cows was 8579 kg of milk per lactation. With parity increased milk yield per lactation. As well as the average daily milk production and average milk production per day of calving interval. Insemination index and days open length were significantly longer for 2nd lactation where a large increase in milk yield negatively affected these parameters. Furthermore, we evaluated the lifetime milk production. The highest average yield per lactation reached cows cullet later than on 4th lactation. In these cows was detected milk production per lactation for 1000 kg higher than in cows that finished only 2 or 3 lactations. The lowest average yield per lactation was in cows that finished only two lactation. Furthermore, cows were evaluated according to the lactation curve. It was found that with increasing lactation persistence increases milk production but deteriorate the reproduction traits as a days open, insemination interval and insemination index. It was also found that with increasing lactation persistence decreases the longevity. Furthermore, we observed the level of milk productivity according to insemination index and found, that with increasing milk production increase insemination index.

The aim of this thesis was to compare the reproductive performance of sows on two farms within a selected company, which is engaged in breeding pigs. There were observed phenotypic level of selected reproductive parameters, namely the total number of piglets born, number of piglets born alive and number of weaned piglets. These reproductive performance were also compared depending on the order of litters and the length of pregnancy. The evaluation of the results we can say that the best reproduction performance were achieved in 2014 on a farm A, namely 15,00 pcs of all born piglets per litter. Live born and weaned piglets per litter were found most in 2015 on a farm B, namely 12.56 pcs / litter of live born piglets and weaned piglets - 11.67 pcs / litter. In comparison reproductive performance in the sequence of litter in the number of live born piglets were the best third and subsequent litters on the farm A - 14.66 piglets per litter. The most live born piglets were found in the third and subsequent litters on the farm B - 12.58 piglets per litter. The highest number of weaned piglets were found again in third and subsequent litters, namely 11.64 piglets per litter on the farm B. The evaluation of influence of the length of pregnancy on the reproductive performance is obvious that the best results in all parameters was achieved at a length of pregnancy in the interval from 111 to 113 days. All born piglets per litter were found 15.2 pcs / litter on the farm A and live born piglets per litter were the most on the farm B - 12.55 pcs / litter. The most weaned piglets were found on the farm B - 11,70 pcs / litter. Losses of piglets from birth to weaning were recorded at least on the farm A in 2015 - 5.73% of piglets born alive and on the farm B in 2014 - 6.69%. Depending on the order of litter was the best result achieved at the farm and for sows in the second litter, when losses were recorded only 0.09% of piglets born alive. The best result of losses in relation to the length of pregnancy was achieved on farms A 3.24% at the length of pregnancy in the interval from 117 to 119 days
