Svoboda, Václav ; Stádník, Luděk (advisor) ; Dana, Dana (referee)
This bachelor thesis is focused on breeding calves during the milk nutrition. In the first chapters of the work is through literature review processed growth, development, nutrition and technology that is stabling calves. Next there are investigated factors influencing the development of the calf, birth and the most common diseases of calves.
In the last part of bachelor thesis was observations made during the rearing period in dairy nutrition. For the practical assessment was used 2 farms Zemědělské společnosti Dobříš s.r.o., okres Příbram. The particular farm was Dražetice, which uses the rearing of calves in individual outdoor boxes and farm Mokrovraty using individual boxes under a shelter. In other aspects of breeding farms were similar.
For monitoring was selected a total of 20 calves of which 5 bullocks and 5 heifers from each of these farms of agricultural companies. In December 2015 there were monitored weight of calves within 24 hours of birth weight at weaning (60 days of age) and the state of health of the calves. From gathered data was calculated average daily weight gain and the total weight gain for the period.
Better observation of the farm came from Dražetice, where average daily weight gain amounted to 1,053 kg, calves at weaning were reaching an average weight of 98,7 kg and there were no observed disease.
Farm Mokrovraty fell slightly worse, where average daily weight gain amounted to 0,943 kg. Calves at weaning were reaching the average weight of 92.4 kg and there has been observed one case of diarrhea on one of the calves, which caused its individual average daily weight gain to 0,82 kg and weaning weight at 85 kg.
One of the most important things when you rearing calves is quality and conscientious work. At farm Mokrovraty would be better to retrain and motivate staff to improve the work done. At last both farms could invest into technology for supply buckets with sucker, for better food salivation, instead of classic buckets, to improve rearing calves.
