The results of research and the experiences of dairy industry activists have proven that achieving height and weight standards in heifers through proper nutrition will play an important role in their future performance as dairy cows. On the other hand, to reduce feed costs and improve the growth of heifers, heifer-rearing commercial centers, try to wean them early, which requires the faster development of the digestive system and rumen of calves. The use of a suitable starter enables access to this goal.
