Age growth dynamics of calves when feeding Zeo-Amino® feed additives

The effectiveness of dairy cattle breeding is largely determined by the intensity of growing healthy young animals. The growth dynamics of calves in milk production complexes is of great economic importance, since animals with increased growth intensity, all other things being equal, consume significantly less nutrients per unit of body weight gain. At the same time, the growth dynamics of young animals should ensure that the optimal level of development of heifers is achieved by the time of the first insemination. The article presents data on the effectiveness of the use of ZERO-AMINO® brand feed additives in the diets of young cattle of different ages. It was found that feeding the studied additive based on modified zeolite enriched with a complex of amino acids and additionally artichoke extract as a hapatoprotector increases the growth dynamics of calves at different ages.
