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

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%

Sanitary assessment and technological indicators of goat milk

Milk and dairy products are indispensable for the full development and functioning of the body. In recent years, the demand for goat’s milk has increased. It has long been considered a source of health, especially in relation to people suffering from allergic diseases (including cow milk protein), with metabolic disorders, digestive disorders, etc. That is why the problem of obtaining high-quality goat milk is relevant and practically significant. Over the past few decades, interest has grown in a variety of biologically active substances of natural origin for their use as components of the diet of farm animals. Unlike antibiotics, growth stimulants and other synthetic drugs, phytogenics can be used in healthy animals for most of the productive period, providing a positive result in terms of quantity and quality of products. Based on this, we studied for the first time the effect of the plant product of stevia processing on the veterinary and sanitary indicators of goat milk. An experimental group of goats received stevia pulp together with the main diet. During the experiment, we found positive dynamics associated with the productivity of the goats of the experimental group. The use of an experimental feed composition provided positive dynamics in terms of the main indicators characterizing the technological value of milk. Thus, based on the data obtained, it should be concluded that the use of stevia pulp in combination with the basic diet provides positive dynamics for technologically significant indicators of goat milk, as well as increases the productivity of animals and ensures the production of products with high veterinary and sanitary characteristics
