Namakkal and Karur districts of Tamil Nadu were purposively selected for the present study, a total of 83 (64 cow and 19 buffalo) milk fever affected dairy animals were selected through purposive sampling technique from these districts. The log odds of the animal going to be affected by milk fever enhanced by 18.695 and 3.226 times, when breed and parity changed from 0 to 1 (in ceteris paribus). Similarly, when other indicator variables viz., post partum disorders (metritis and retained foetal membrane), summer season and non supplementation of mineral mixture influenced the log odds of the milch animal for being affected by the milk fever were to the tune of 17.908, 2.866 and 74.772, respectively.enArticle
