High Milk Production and Reproduction Results - Miner Institute

Researchers at the Miner Institute observed a significant improvement in reproductive performance when cows were supplemented with Zinpro complexes vs. slightly higher level of trace minerals provided from inorganic sources (63; Figure 2). In the study, high producing cows averaging almost 45 litres/day were fed diets fortified with zinc, manganese, copper and cobalt at levels several times higher than the requirement (46). Cows fed Availa^®4 had fewer days to conception and at 150 days post calving, 95% of cows fed Availa-4 were pregnant versus 61.1% of cows fed the inorganic trace mineral diet (38). Availa-4 cows also produced numerically more milk solids (protein plus fat) than control cows (63).
