New farm experience on how X-Zelit influence production traits from Latvia
The main interest was on the metabolic diseases in the period just after calving. Basically, all production parameters were improved, e.g. reduced subclinical and clinical milk fever, reduced retained placenta, reduced metritis. The improvement in these production traits is what pays off using the X-Zelit product.
The individual farm improvements can be seen in the 4 tables below:
