Vitamin B1 is one of the most essential elements of metabolism and multiplication of Eimeria spp, responsible for coccidiosis in poultry. Without B1, Eimeria spp cannot survive. So, it is advised to stop vitamin B-complex preparation as it contains vitamin B1 during coccidiosis in poultry. But, at the same time other B vitamins play a great role in red blood cell (RBC) production, metabolism and other physiological activities in poultry. So, it is not wise to stop B-Vitamins only for vitamin B1. B-Com Vit Liquid is such a preparation where vitamin B1 is absent. As a result B-Com Vit Liquid can be used in poultry at any time regardless the occurrence of coccidiosis.
