Analysis of Holstein dairy cow breeding
Váchalová, Veronika ; Toušová, Renata (advisor) ; Ducháček, Jaromír (referee)
The bachelor thesis deals with the breeding of Holstein dairy cattle within the system of intensive agriculture. The first chapters summarise the history of the breed, its origins and utilitarian purpose. The following chapters describe the systems of stabling, feeding and milking. The main factors affecting the economy include the quality and production of milk, as well as reproduction of dairy cows.
The practical part is engaged in the evaluation of reproduction and milk production at the farm in Tlumačov, which belongs under the Mrákov collective farm in the district of Domažlice. The farm had 239 cows of the Holstein breed in 2015. Their results were evaluated on the basis of milk utility control sheets for the period from 1st January 2015 to 31st December 2015. I divided the monitored herd into 3 groups: cows in the 1st, 2nd and 3rd lactation. I focused on the comparison of the total milk yield, milk fat content, protein percentage and number of somatic cells in all three groups. The results showed that the average milk yield of the entire herd for 2015 was 10,064 kg with an average fat content of 384 kg (3,81%) and milk protein content of 328 kg (3,26 %). As for the number of somatic cells, the average value 130,000/ml achieved by the farm in Tlumačov is very good. The best results were achieved by cows in the 1st lactation, with the average value of 70,000/ml. Their milk therefore is in compliance with the highest quality requirements.
Reproduction was evaluated by basic parameters. The results showed that gravidity after the first insemination reached satisfactory values for heifers as well as cows. Although the service period was shorter than optimal, according to various literary sources it is tolerable. The insemination index for heifers was evaluated as very good. Cows also achieved a good result in this parameter in 2015.

MOTYKOVÁ, Markéta
This bachelor thesis is evaluating results of primary herd of rows remedial program. It i also about following the principles of correct zoohygiene and veterinary prevention, then about reviewing the influence of remedial program on reducing respiratory diseases occurrence. It also pursues parametres rows's reproduction yield in herd and follow-up pre-fattening and fattening.Given to these circumstances my goal was to evaluate the results of remedial program of whole pigs herd in ZD Bělčice, to assess following the principles of correct zoohygiene and veterinary prevention and also to evaluate the results of reproduction and loses for a year before repopulation of stud (2012) and after the repopulation (2014). I also focused on comparing the results of yield using parameteres like number of living newborn piglets, weaned piglets, lost piglets in pre-fatteing and fattening for those two mentioned years. I focused on following hygienic loop of operation, observing cleanliness and desinfection. I also observed preparation, washing, desinfection of sows, which are removed for farrowing. Next I dealt with hygiene and desinfection during veterinary interventions and with keeping feeding belts and mixer clean. I observed monitoring of regular controls and analysing food samples and then regular monitoring of samples examined for respiratory diseases in this stated herd. I observed visits on farm, respecting restrictions of accessing the herd. At the end of my thesis are all mentioned requirements evaluated.

Health assessment of the selected pig management
SKÁLOVÁ, Eva
Aim of the thesis is to evaluate health in selected pig stock. Adherence to vaccination programs and good veterinary prevention principles, provision of appropriate stall, good care and feeding, piglets wean timing, selection of breeding animals, choosing of reliable personnel and other factors have great impact on health in pig stock. Considering above mentioned factors, the aim of the thesis was to asses health of sows, piglets and fattening pigs in chosen farm Ponědraž ltd. and asses influence of vaccination on production in time period 2010 to 2011. Further it was neccesary to asses observance of good hygiene praxis in enterprise, including using of hygiene loop by personnel and to find out, if the enterprise is equiped with systematic protection against infectious diseases. To evaluate stall by pig categories, animal welfare and positive influence on health and increase of pig production as a whole. Further to asses compliance with EU legislation. Aim of the thesis is to evaleuate new vaccination scheme against respirational diseases, it´s influence on increase of production and improving of healt in observed stock. In the end are all above mentioned requirements evaluated.
