The qualitative composition of milk of cows when feeding of the drug "Aminobiol"

The aim of the work is to study the effect of the preparation of free amino acids -"AMINOBIOL" on the qualitative composition of cow milk. Organized exhibition experiments on cows of black-and-white breed aged 3.5 to 8 years, live weight from 500 to 600 kg, which formed into two groups: 1st-control, 2nd-experience. Experience spent 30 days in the conditions of private dairy farms of the Ulyanovsk region of the Russian Federation. Cows were fed the same commercial diet (MD). The drug, depending on the live weight of cows 1 cm3/100 kg was given with bread 100 g before morning feeding. Group 1 did not receive the drug. The qualitative composition of milk was determined on the analyzer "lactan 1-4", "AKBA-01-BIOM", the account of milk productivity was conducted daily. In milk is determined by: QMAFAnM (direct method), coli-titer (fermentation test), the qualitative composition of the microflora. Analysis of milk productivity of cows using the drug "AMINOBIOL" showed that there was an increase of milk yield by 8.13...to 26.08 %, the content of fat, protein, SNF, lactose, quantity of milk fat and microbiological safety of milk.
