Abstract

The article presents the research results of the effect of activated diatomite as part of a complex supplement on the composition and ratio of saturated and unsaturated fatty acids in cow's milk. The experiments were carried out in a dairy farm on black-and-white cows. The additive includes a carrieractivated diatomite; fillers are DAPS-organic selenium, sunflower oil and feed yeast and diatomite crumbs. The supplement was included in the diet of cows at the rate of 2% of the dry matter of the diet once a day. The control group did not receive the supplement. The positive effect of the use of the additive on the composition of fatty acids in cow's milk was established. There was an increase in the fraction of saturated fatty acids, which indicates an increase in volatile fatty acids: acetate and 3-hydroxybutyrate. The use of a complex supplement based on activated diatomite contributed to an increase in concentration of capric, lauric, myristic, palmitic and margarine fatty acids. The use of additives for dairy cows helps to increase their productivity, improve the quality of milk composition due to the intensive conversion of feed nutrients.

Highlights

In order to obtain organic products in the field of dairy farming, the scientific search and development of new and highly effective feed products based on natural components are relevant [1,2,3].Scientists' attention is drawn to the discovery of special properties of silicon-containing minerals: ion exchange, adsorption, detoxification, supply of silicon and mineral elements
Silicon helps to ensure the storage of calcium and other minerals in the bone; if silicon is removed from the diet, calcium is removed from the bones
The aim of the work was to study the effect of silicon-containing complex supplement based on activated diatomite on the fatty acid composition of cow milk

Summary

Introduction

In order to obtain organic products in the field of dairy farming, the scientific search and development of new and highly effective feed products based on natural components are relevant [1,2,3].Scientists' attention is drawn to the discovery of special properties of silicon-containing minerals: ion exchange, adsorption, detoxification, supply of silicon and mineral elements. The ability of silicon compounds to adsorb amino acids and protein provides their rapid absorption in the stomach and intestines and increases the assimilation of feed [4,5]. Silicon helps to ensure the storage of calcium and other minerals in the bone; if silicon is removed from the diet, calcium is removed from the bones. The regulatory role of silicon in body is significant. Mineral homeostasis is normalized and body absorbs the nutrients of the feed [6]. Any disbalance and a lack of silicon in body lead to disorders and contribute to the development of diseases: bone softening; diseases of eyes, teeth, claws, skin and hair, cartilage; stones in liver and kidneys; atherosclerosis [7]
