Feeding replacement calves of 369-460,8 kg of live weight with diets of non-degradable protein level that is 10% higher than approved norm increases metabolically energy transformation into weight gain energy from 19,10 to 20,81 MJ or at 9% that promotes increase of average daily weight gains at 5% and decrease of energy spends at 5% counted per 1 unit of energy for weight gain. Ejaculate volume is increased at 14% and sperm concentration – at 12%
