YIELDS AND QUALITY OF MILK PRODUCED BY COWS FED ON RATIONS, INCLUDING VITAMIN-MINERAL FEED ADDITIVES
The aim of the research was to study the effect of including bentonite clay, premix and granulated concentrates in the rations of dairy cows on their milk yields and its physico-chemical composition. The study was conducted in winter on the A.Yusupov farm enterprise in the Gissar region, Republic of Tadzhikistan, on four groups of high-yielding Black-Spotted cows of the Tadzhik type of the 3rd lactation, with their milk yielding capacity being 5-6 thousand kg of milk for a lactation period. The inclusion of the above additives in the feed diet of cows contributed to the increase of feeds digestibility, their nutritional and biological value, as well as to higher milk yields and to milk quality improvement. This led to certain decrease in feed consumption per unit of output and increase in the level of profitability of milk production in the zone of intensive farming in the Gissar Valley of the Republic of Tadzhikistan. As to the physicochemical indices, higher quality milk was obtained from cows fed on rations supplemented with vitamins and minerals (premix RUMINAT (100 G/J) - 100 g and granulated commercial concentrates - 5 kg.
