Evaluation of the quality and safety of cows' milk when using the mineral elements

Abstract

A successful feeding program should solve the following problems: achieving planned milk production, increasing dry matter intake and improving ruminal microbiota. As an integral part of the diet, feed additives have an impact on the animal's body, which is expressed, for example, in an increase in average daily weight gain, a decrease in conversion, an improvement in metabolic metabolism and so on. However, it should be noted that feed additives alone do not guarantee of high productivity or profitability of milk production. The purpose of these studies was to evaluate the effect of the multicomponent feed additive Felucen on the sanitary quality and safety of cows' milk. The studies were conducted on the basis of training and experimental farm, where two groups of dairy cows, 40 heads each, were formed according to the principle of analogues. All cows of both groups received the basic diet accepted on the farm. Additionally, the first group received Felucen feed additive at the rate of 5 g per 1 kg of body. Analysis of the milk composition and productivity was carried out on the 10th, 30th, 60th and 90th day. The use of Felucen provided an increase in the milk productivity of cows by 11% and an increase in the quality indicators of milk: the mass fraction of fat increased by 0.11%, protein - by 0.21%, lactose - by 0.20%
