SUCCESS FACTORS FOR A HIGH COW FERTILITY

Maintaining and improving fertility is always a subject of concern when it comes to high-producing dairy cows. Fertility depends on many factors such as insemination management, lactation number or milk production only to name a few.

Another major parameter influencing fertility in cows is the sufficient supply with trace minerals, especially as cows have to conceive during a period of extremely high milk production. Supplementation of highly available sources of trace elements are a helpful tool to ensure sufficient supply. Our MAXCHELAT products (zinc, copper, manganese and iron bound to the amino acid glycine) have proven their superior bioavailability in numerous extensive trials.

During a field study with 60 cows, the superior bioavailability of MAXCHELAT translated into a reduction of the interval between calving and first day of pregnancy by 11 days and a lower insemination index (0.42 points improvement).
