When AB Neo OptiPartum-C is added to the postpartum ration, it boosts intake and helps to unlock the performance of the cows' diet. OptiPartum-C uses proprietary formulation and process technology that works through the synergistic combination of naturally occurring appetite enhancers and uniquely activated ingredients. When using OptiPartum-C, there is a potential cost saving through reduced use of protected fat with milk yield or constituents maintained or improved. Other features include improved body weight during the postpartum period, improved fertility associated with reduced body condition loss during the postpartum period, and increased milk yield or constituents when added to a fat-free ration.
