Abstract

Studies on the effectiveness of the inclusion of sodium humate in the diet of young cattle were conducted on four groups of animals. Installed improvement in the consumption of hay by the bulls of the experimental groups by 12.5–20 % compared with the control young was found, as a result of which they consumed more feed units by 1.5, 2.3, and 3.5 %, exchange energy – by 2.4, 3.9 and 5.1 %, digestible protein – by 1.2, 2.1 and 3.7 %. As a result of the inclusion of sodium humate in the diet as part of the KR-2 compound feed, the amount of hemoglobin in the blood of animals of the II experimental group increased by 5.8 %, in III – by 6.8, in IV – by 7.8 % compared to control analogs. With the growth of calves in the blood, the bactericidal activity of blood serum increased by 1.3, 1.9, and 2.5 %, lysozyme activity increased by 0.1 %, 0.2, 0.3 %, which indicates an increase in natural resistance in animals whose diets were injected with the studied peat and sapropel preparation. The use of sodium humate in the feed of bulls in the composition of compound feed KR-2 has a positive effect on the feed consumption, physiological condition, resistance of animals, which provides an increase in the average daily increase in live weight by 3.2–9.4 % while reducing the cost of its production by 2.9–8.5 percent.

Highlights

Feeding of farm animals must be carried out according to detailed standards, taking into account the chemical composition and nutritional value of the feed used
The purpose of the research is to study the effectiveness of sodium humate in feeding young cattle
The differences in feeding consisted in the fact that the bulls of the experimental groups were fed sodium humate in doses of 0.4 (II-experimental), 0.5 ml (IIIexperimental), and 0.6 ml (IV-experimental) per 1 kg of live weight

Summary

Introduction

Feeding of farm animals must be carried out according to detailed standards, taking into account the chemical composition and nutritional value of the feed used. This makes it possible to more fully balance the diets, thereby increasing the productivity of animals at the exact feed costs (Slavetsky, 2002; Razumovsky et al, 2002; Yakovchik & Ganushchenko, 2011; Johansson et al, 2012; Amamou et al, 2019; Borshch et al, 2021; Denkovich et al, 2021; Mylostyvyi et al, 2021). Such products support physiological health and reduce the risk of diseases (De Oliveira et al, 2011; Acedo et al, 2011; Bogdanovich, 2019; Bogdanovich & Razumovsky, 2019; Radchikova et al, 2019; Bogdanovich & Razumovsky, 2020)
