ABSTRACT

The studies have shown that the level of milk productivity, the character during the lactation, the yield of dairy products per 100 kg of live weight and the payment rate for feed by dairy products of Simmental cows are interconnected with body types. For dairy cattle, milk yield for lactation is 672,5 and 958,5 kg, respectively, for milk with 4% it is 507,4 and 735,4 kg higher, milk yield for every 100 kg of live weight is 164,9 and 228, 7 kg more than the peers of the dairy-beef and beef-dairy types. The highest monthly milk yield of dairy cows was noted in the third while for dairy-beef and beef-dairy type cows in the second month of lactation. This indicates that in dairy cattle, lactation proceeded more evenly than in peers of other types. The obtained data reveals the high efficiency of the use of dairy cows for the production of milk.
