Nutritional value of meat products of young stock of black-and-white breed and its crosses with Holstein

Abstract

The article presents the results of monitoring the chemical composition of the average sample of minced meat, energy value, yield of nutrients and their ratio in meat products. The positive effect of crossing black-and-white cattle with Holstein on the nutritional and energy value of meat products has been established. This contributed to an increase in the gross protein yield of carcass pulp by 3.62–5.27 kg (9.50–13.83%), extractable fat — by 1.59–4.60 kg (5.39–14.80%) , energy concentration in 1 kg of pulp — by 506.5– 568.8 kJ (5.34–5.46%).
