Possible effect of patogens on fttness of selected duck species
Langrová, Anna ; Votýpka, Jan (referee) ; Musil, Petr (advisor)
In total, 76 birds, mainly breeding females, were captured in years 2007-2009. Birds were inspected for the presence of avian influenza (AI) viruses and the AI antibodies. They were inspected as well for the presence of bacteria Borrelia burgdorferi s. l. and Anaplasma phagocytophilum and protozoan Leucocytozoon simondi in blood. The feces were examined for the oocysts and eggs of intestinal parasites. AI viruses were found in 4 cases, while over 80% of inspected birds had AI antibodies. Bacteria B. burgdorferi s. l. and A. phagocytophilum were found in 2 and 1 case respectively. Protozoan L. simondi was not found in any blood smear. The oocysts from protozoan genera Eimeria and Tyzzeria and eggs from roundworm genera Capillaria, Amidostomum and Echinuria were observed in feces. Statistical analyses were due to the small size of our data set inconclusive.

Relationship between body condition and production traits in cattle
Smolíková, Barbora ; Hofmanová, Barbora (advisor) ; Majzlík, Ivan (referee)
This thesis summarizes findings from research on influence of the body condition on production traits in cattle. The body condition is indirect indicator of negative energy balance and it has informational character about overall conformation of a cow. Managing body condition allows to influencing production traits. Lower body condition score is associated with higher milk yield, though the content of milk components (fat, protein, lactose) is in positive correlation with higher body condition. This is reflected especially in high yielding cows that have low body condition and high milk production, but problems with reproduction. Mature size, muscularity and fertility positive correlate with body condition. Increasing body condition improves reproductive performance. Particularly open days seem to be a great indicator of total herd fertility. Too thin or fat cows have lower efficiency. However it is necessary look out body condition more in thin cows, where worse efficiency is more shown and health problems threaten.
Results of studies indicate that it is possible to use body condition score as selection criteria for indirect improvement of some traits. Optimal body condition can improve economic viability of cattle breeding.

Vliv vybraných faktorů na průběh porodů a výskyt poporodních poruch u dojného skotu
ČERNÁ, Radka
The bachelor´s thesis aims at calving issues. Data for this study were collected through the monitoring of a dairy herd conducted from June 2014 to April 2015. The delivery course of breeding dairy cows was monitored including occurrence of postnatal complications, the care of a breeding-cow and evaluation of occurrence of health malfunction during the peripartum period in relation to the Body condition scoring of dairy cows and to the length of a non lactating period. Data suggests that breeding-cows have very good conditions during the non lactating period. Cows have Getting Enough feed, the option motion and grazing. Breeding-cows are most frequently in their optimal form (3-3,5). Course of labor was most often classified at level 1, as an easy birth. Disfunction of postnatal period was rare on the farm during the period of monitoring. A retained placenta was the most frequent disfunction.

Kondice holštýnských dojnic a vlivy které na ni působí
Úradníčková, Hana
Bachelor thesis focuses on the analysis of the influences acting on the body condition Holstein cows and their own assessment of body condition. The main part deals with the evaluation of body condition Holstein cattle and influences that act on it. Then the thesis reviews the body condition for further farm animals and hobby animals. I made two observations of cows at first lactation in the ŠZP Žabčice. Of these cows were selected 48 pieces, it is at each observation 24 pieces of which 12 cows were in the stage of lactation in 100 days and for 12 cows over 100 days. The first sighting took place in November 2014, and the second in February 2015. In my observations, I focused on the analysis of two influences, and how it affects month follow-up (November, February) and stage of lactation (within 100 days and over 100 days).The results observed were as follows. When monitor the influence of the month sighting on the body condition, the mean BCS (Body condition score) in November it was 3.11 points and 2.97 points in February. The average of the lowest values observed in November was 2.47 points and 2.56 in February. The average of the maximum values reached in November 4 points and 3.56 points in February. Regarding the influence of stage of lactation, the values of average body condition at the stage of lactation of 100 days 2.98 points and over 100 days 3.1 points. The average of the lowest values in the phase of 100 days was 2.47 points and over 100 days 2.56 points. The average of the maximum values reached within 100 days of lactation 3.84 points and over 100 days of lactation 3.91 points.

Evaluation of the reproduction and milk performance of Holstein cattle
PEŠTA, Vladimír
The main aim of the diploma work is to evaluation the reproduction level and the milk performance level of the concrete herd of cattle Holstein breed. The evaluation took place in family farm of Vladimír Pešta. The farm manages 73 hectares of soil and keeps 40 cows with closed herd turnover. Collection of input data took place in the years 2004 - 2007. There were monitored basic indicators of milk performance, indicators of reproduction and the development of body condition score (BCS) during the lactation period. The increasing milk production of the groups with performance to 7000 kg, 7000 {--} 8000 kg and over 8000 kg of milk affected negatively indicators of reproduction and there were the statistically demonstrable differences between groups. The duration of service period (SP) of groups by performance was 154, 165 and 175 days. Order of lactation period had no effect on reproduction. The milk production was by 1st lactation period 6 909 kg, by 2nd lactation period 8 435 kg and by 3rd lactation period 7 894 kg. There was the higher milk production by the dairy cows, which were calved in spring and in autumn, and it was 7 822kg and 7 898 kg. The dairy cows, which were calved in winter and in summer, had the performance lower by 400 kg. There were reached the better reproduction results by the dairy cows calved in winter and in spring, SP 164 and 153 days. The dairy cows calved in summer and in autumn had SP 174 and 182 days. The differences between the groups by season of year were not statistically demonstrable, neither at reproduction nor at milk production. The size of body framework of cattle had no effect on the milk production. The average value of body condition score on the beginning of lactation period was 3.59 points. The value of BCS was decreasing until 6th month of lactation period on 2.43 points. In the next months the BCS was slowly improving. The values of BCS oscillated during different phases of lactation period in range of 2 points. In the days of gestation the value of BCS was 2.65 points. The rate of the milk component fat/protein was on the beginning of lactation period 1.75, until 4th month of lactation period decreased on 1.35 and in the next months the rate was oscillated between 1.3 and 1.4. The average age by first calving was 834 days (27.4 months). By increasing age by first calving the subsequent performance sloped down. But this relationship was not statistically demonstrable. The average tallness in the small of the back amounted by cows, which are calving for the first time, to 149.8 cm. The attained milk performance was satisfactory. The reproduction results were less favourableness. From recognized relationships we can draw conclusions, that on the production and reproduction of the monitored herd the breeding conditions, the nutrition, the health state and the herd management have an mainly influence. By improvement of these factors we can achieve the better reproduction results. The influences like the season of year or the body framework of cattle are not too important.
