Influence of Different Levels of Milk Feeding on the Growth and Development of Calves

Abstract

AbstractStudies of the development of the rumen, abomasum and reticulum in the rearing of bull calves have been carried out. Different types of bull calves rearing in the first five months of life led to significant differences in the growth and development of the whole organism and all its individual organs and tissues, mainly in favour of bull calves raised with replacing part of the milk with vegetable feed. Differences in rearing schemes influenced the histological state of the tissues of the rumen, reticulum and abomasum. It has been established that the rearing system with a decrease in the drinking of whole milk and abstinence of the supply of roughage for the first two months of life, promotes the growth of animals, leads to an increase in the yield of veal and beef meat, a decrease in feed consumption per unit of weight gain, and increasing the profitability of production, therefore it is recommended for production.KeywordsHistological studiesBull calvesRumenAbomasumEnvironmental sustainability
