The effect of a forest biomass supplement on morphophysiological parameters of calves

Abstract EN

Breeding, preserving, and successfully rearing young animals resistantto various environmental influences is one of the main parameters of effectivelivestock management.

The study aimed to study the indicators of natural resistanceand the growth rate of calves under the influence of dietary supplements.

Thestudies were carried out on four groups of black-and-white calves, 10 heads each, atthe age of 2-5 months.

The dairy calves of the control group were fed according tothe ration adopted on the farm (basic ration, including cereal-legume hay, wholemilk, milk replacer, concentrates, chalk, salt).

In addition to the main diet, theanimals of the experimental groups were given a dietary supplement.

At 2-3, 3-4, and 4-5, months of age, calves were given 12-23, 19-38, and 23-47 g.

head-1 ofdietary supplement per day, respectively.

The article deals with the effect of a forestbiomass supplement on the morphophysiological parameters of calves.

Biochemicalblood analysis and the features of metabolic processes in the bodies of animals arestudied.

The results indicated that the use of a dietary supplement at a dosage of 30g/head of cattle per day contributes to the highest increase (9.9% ) in live weightgain of experimental animals and an improvement in natural resistance parameters(bactericidal activity of blood serum, phagocytic activity of neutrophils).

Based onthe data of biochemical and haematological blood tests, the authors conclude thatthe inclusion of a dietary supplement in the diet of calves has a positive effect onthe indices of natural resistance and the course of nitrogen metabolism.
