Analýza užitkovosti prasat ve vybraném chovuČadová, Marie January 2018 (has links)
The aim of the thesis was to evaluate the reproduction and production indicators from the data obtained and processed on the selected farm. Farm indicators were evaluated between 2013 and 2017 and 200 sows were selected from multiplier herds for which selected reproductive indicators were evaluated. The reproduction indicators were evaluate the number of all born piglets, the number of alive piglets, the number of weaned piglets and the stillborn piglets from birth to wean by parity and gestation length. The highest number of all born piglets and weaned piglets per year was reported by the farm in 2017. 15, 6 ± 3.3 pcs of all live piglets were born and 11.9 ± 1.6 pcs of piglets per litter were weaned. The average was weaned 1.8 ± 2.9 piglets. In terms of production indicators, the average daily gain and feed conversion per 1 kg increments for the pre-fattening and fattening category were evaluated by year and season. The highest average daily gain in both categories was found in 2015, in pre-fattening it was 414.7 ± 18.9 g/day and in fattening it was 813.8 ± 34.1 g/day. For the feed conversion indicator, the lowest values were found in 2015. In the pre-fattening category feed consumption per kg of gain it was 1.79 ± 0.19 kg and in fattening it was 3.01 ± 0.19 kg/kg.

Vztah hladiny imunoglobulinů v krvi telat k jejich pozdější mléčné užitkovosti a zdravotnímu stavuDrozdová, Michaela January 2018 (has links)
In order to analyze the relation of the level of immunoglobulins in calf blood to their later milk performace and health status, the necessary data from 495 pieces of holstein breeds were collected in 2014-2017. On the basis of the analyzes performed, it can be stated that the level of immunoglobulins in the calf blood had no conclusive effect on their later production of milk, fat and protein. In terms of health, higher blood levels of immunoglobulins were associated with a significantly lower incidence of metritis and lower incidence of mastitis (at the limit of evidence), but no significant effect on ruminant disorders. Immunoglobulin levels in calf blood were proven to be affected by the difficulty of delivery, the quality of the colostrum during the first feeding, and volume of second feeding. At the limit of proof was the influence of season and the quality of the colostrum on the second feeding. Inconclusive effects were reported by daily birth time, daily time of feeding and volume of first feeding.

Analýza užitkovosti v ekologickém chovu kozBerková, Veronika January 2018 (has links)
The goal of this thesis is the analysis of the milk yield on a particular organic farm breeding goats. The milk yield was monitored and evaluated in the control range 2015-2017. The data was obtained from the yield checks carried out by SCHOK (Association of Goat and Sheep Breeders) and from the farm's own records. The testing was run on 526 White Shorthaired goats yielding 760,08 kg of milk for standard lactation with a fat content of 3.4% in 2017. There has been a trend of rising milk yields on the farm since 2015 when the yield reached 627.77 kg of milk with a fat content of 3.02%. This trend was statistically highly potent (P<0.01), as well as the protein content (%) in milk which has dropped from 2.97% to 2.73% during the the same period of time. In addition, 184 goats on the 1st lactation and 177 goats on the 2nd lactation belonging to 16 father lines were evaluated. These lines were compared to each other by individual milk yield indicators. In the lactose content (%) the Krasus line dominated (4.83%) which showed statistically significant difference (P<0.05) compared to the Molch and Emil lines whose lactose content was the lowest (4.51% and 4.53% respectively). The 2nd lactation testing evaluated the number of somatic cells in the milk, with an average value of the group monitored being 1543.12 thousand of somatic cells per one mililiter. The highest number of the SC was measured in the Bera line (4437.17 thousand SC/ml) with statistical conclusiveness (P<0.05) compared to Bernd (758.5 thousand SC/ml), Curt (858.42 thousand SC/ml), Zub (444.24 thousand SC/ml), and Zuzek (696.77 thousand SC/ml) lines which reached the lowest values. In other observed milk yield parameters, the lines on both lactations showed marked differences in the values achieved but they were not statistically proven.

Vliv různých typů podestýlky na parametry mléčné užitkovosti dojnic holštýnského skotu ve vybraných chovechMaňáková, Michaela January 2018 (has links)
The aim of this diploma thesis was based on analyze and following synthesis evaluated the effect of different types of bedding on milk performance parameters dairy cows of Holstein cattle. The experiment was carried out during one calendar year (February 2017 to January 2018). The monitoring was carried out once a month, one day after performance check in three selected farms – Company A (Farma Zdeňka), Company B (ZOD Lešná), Company C (ŠZP NJ). In the companies was used high bed with manure separation and ground limestone, a high bed covered with straw, deep bed with a sandwich of the first type with a layer of separating manure and ground limestone and deep bedding. Between milk performance parameters were included data of the order of lactation (n), days in milk (n), milk production (kg), content of fat (%), content of protein (%), number of somatic cells in thousands in 1 ml (PSB in thousands/ml). At the same time was determined the air temperature (° C). The results shows that the best type of housing cows was housing with deep bed with with a sandwich of the first type with a layer of separating manure and ground limestone according to number of somatic cells in the milk (145,6 thousand/ml) and the occurrence of mastitis (2,9%), as well as the milk production (36,9 kg) and the milk components content (3,9% fat and 3,4% proteins). The highest number of somatic cells (company B 419,3 thousand/ml and company C 378,9 thousand/ml) and the highest percentage of clinical mastitis (7,7% in company B and 5,7% in company C) were achieved dairy cows housing on high beds with a separation manure at companies B and C.

Srovnání vývoje a produkce včelstev zimovaných na zásobách z invertního a řepného cukruMusila, Jan January 2017 (has links)
This thesis is focused on nutrition specifics of honeybee (Apis mellifera) and its ontogenetic stages, particularly on carbohydrates. The effects of sugar beet saccharose and invert syrup made from sugar beet as feeds for winter stores supply on overwintering, bee colony condition in early spring and the consequent honey yield were evaluated. In total, 70 bee colonies were included in the field experiment. The experiment was made on 6 apiaries in 4 locations within the Czech Republic. The thesis deals with particular tasks associated with chemical components which have negative impact on honeybee and which might occur in artificial feeds. It suggests potential solution of their appearance reduction in bee feeds. Problematics of honey adulteration regarding the type of used bee feed are discussed.

Vliv doby dojení na intenzitu zalehávání boxově ustájených dojnicDosedlová, Jitka January 2017 (has links)
The aim of this thesis was to analyze the influence of milking period on the inten-sity of lying behaviour of dairy cows kept in boxes. An ethological observation was carried out at the agricultural company GenAgro Říčany corp. on the breeding of Czech fleckvieh cattle. I mainly observed the intensity of the average time of lying in a boxing bed after dairy cows arrival from a milking house, depending on milking time. I have elaborated a literature review and also worked out a methodology on this issue. I have found out that the intensity and the time of lying were above all influenced by seasons and the age, or rather by the order of lactation of the monitored dairy cows, when the longest time to lie took dairy cows during the first lactation. The biggest number of dairy cows lying was during warm months ( July, 122 pcs ), but in a longer interval ( May, 43.6 minutes ) than cows during cold months ( November, 87 pcs ) when more dairy cows were lying, but faster ( November, 32.9 minutes). The fastest cows were lying into the row 1, closest to the feed table, at the average time of 37.8 minutes and most slowly to the row 3, closest to peripheral walls, 42.2 minutes on average. The influence of a particular lactation stage was very slight, the dairy cows above 301 days of lactation lay a little faster ( 38.0 minutes ) in comparison to the ones up to 100 days ( 39.1 minutes ).

Analýza genetického zdroje: přečtické černostrakaté prase / The Analysis of Genetic Source of the Prestice Black-Pie PigHYŠPLEROVÁ, Klára January 2018 (has links)
My thesis "The Analysis of the Genetic Source of the Prestice Black-Pie Pig" deals with the evaluation of the population of the Prestice Black-Pie pigs from the point of view of their numbers, the structure of their population and their reproductive qualities, using the data of the Association of Pig Breeders in Bohemia and Moravia. First the carcass value and meat quality of this original Czech meat bacon breed were evaluated and then a slaughter dissection and laboratory analyses of the meat from the analyzed group of pigs were done. The numbers of PBP pigs have increased significantly especially since 2012 and so has the number of the farms; however in many of them there are fewer than 10 PBP pigs. This is why the PBP pig breeding is rather fragmented and it is difficult to sustain sufficient genetic diversity of the closed population. This is also connected with unequal numbers of the 10 genealogical lines. The Akoga and Amperor lines were the most numerous. Since 2015 the numbers of pigs from different lines have been more balanced. In 2016 two sows from the renewed Apolon line, which had been born from a cryopreserved seed, were put in the farms. The influence of the line was evidential in the statistics: in reproduction as well in productive qualities. Therefore, to sustain sufficient genetic diversity in a small population we need to keep in the stock the maximum number of equally represented genealogical lines. A detailed analysis of reproductive indicators of the years 2013 - 2016 found 9.4 piglets born alive and 8.7 weaned piglets, the farrowing interval of 181 days, the average values of relevant indicators did not meet the requirements of the breeding objective; only one farm met them. Statistically speaking, there were significant differences between the individual farms. In bigger farms there were higher reproductive qualities. Between 1998 and 2016 the average daily gain in weight was 530 g for gilts, 578 g for boars, the muscle fibre ratio for gilts was 58.5 % and for boars 59.3 %, the back fat thickness was the same for both, 1.1 cm. The requirements of the breeding objective were met, except for the lower weight gain for gilts. The average daily weight gain between the years 2009 and 2013 for 577 gilts was 524 g, the average muscle fibre ratio was 59.1 % and the average back fat thickness was 1.03 cm; in all indicators there were statistically evidential differences between individual farms. In bigger farms the muscle fibre share was higher by 0.9 %. In a group of PBP pigs I studied the influence of slaughter weight and gender on carcass value. The statistics clearly showed that the bigger the slaughter weight was, the higher the back fat thickness was, and also the higher the weight of meat parts was, but the share of meat parts was reduced, and the area of MLLT increased, too. The slaughter weight had no influence on the muscle fibre share. The statistics also showed that with the increase in slaughter weight there was an increase in drip loss and the meat was tenderer. There was also a statistically inconclusive increase in intramuscular fat. The statistics also showed that the barrows in the analyzed group had a lot higher average daily gain, a statistically inconclusive higher back fat thickness, lower share of muscle fibre and a statistically conclusive lower share of ham and higher share of intramuscular fat. In the meat of the analyzed group of pigs I studied the content of fatty acids. There was a higher share of undersaturated fatty acids and a high share of n-6 PUFA:n-3 PUFA, which is not considered satisfactory from the nutritional viewpoint.
