MACRO MINERAL LEVELS IN CYCLIC, POST-PARTUM ANESTROUS AND REPEAT BREEDING LOCAL COWS IN LOWER BRAHMAPUTRA VALLEY OF ASSAM

Abstract

An attempt was made to study the macromineral status in cyclic, postpartum anestrous and repeat breeding local breeds of cows in lower Brahmaputra Valley of Assam. The concentrations of macrominerals were highest in Nalbari subdivision and lowest in Dhubri subdivision. When comparison was made among different groups, the levels of macromineral were found to be significantly (p < 0.01) highest in cyclic cows compared to the repeat breeding and post-partum anestrous cows.
