Abstract

The studies indicated in the article were carried out on Aberdeen Angus bulls born in 2021, in the conditions of Nur-Zhailau NS LLP, located in the south of Kostanay region. In conditions of the same content, bulls (Σn=20) of the same age were experimented with the addition of a food additive to the feeding diet. The experimental ruppe was added 0,13 mg per 100 kg of live weight of bulls, a domestic feed additive (premix) AL KARAL. In the course of the study, biometric statistical processing of all data of bulls of the control and experimental groups was carried out, taking into account the live weight of bulls, the absolute and average daily increase from the moment of weaning from the mother and up to 12 months of age.   

As a result of the conducted studies, the bulls of the experimental group were higher in all signs of indicators compared with the bulls of the control group: in terms of live weight at 9 months of age, the bulls of the experimental group by 4,4 kg or 1,9 %, and at 12 months of age, respectively, by 6,9 kg or 2,4 % higher; by an absolute increase of 6-9 at one month of age, respectively, 3,7 kg or 7,4 % higher, at 9-12 months of age by 2,5 kg or 2,9 %, and from birth to 12 months of age by 6,4 kg or 2,2 % higher.
