Metabolism, productivity and reproductive function of highly productive cows in nutriceuticals choline in protected form
Studies were conducted on high-producing cows black-motley breed (n = 70) to determine the optimal standards of feeding choline in protected form (vitamin B <sub>4</sub>) in a production environment. Research and production experience showed that choline diets enriched in protected form (1 g per 1 kg of milk produced) increases milk production by 7% and reduces the cost of feed by 6,4%. The experimental data allow us to recommend to balance rations for choline in protected form (1 g/kg of milk produced) for high producing dairy cows during milking.
