Abstract:
Reproductive activity is influenced by several nutrients which are involved in the synthesis of hormones that are important for reproduction. Macro-minerals like calcium, phosphorus influence the ability of animal to utilize other micro-minerals. Micro-minerals like zinc, copper are involved in the regulation of enzymatic activity at subcellular level which inturn affects reproduction. In the present study eight clinically healthy normal breeding and eight repeat breeding buffaloes presented to the Veterinary Dispensaries in and around Bidar were selected for the study. Mineral parameters viz., calcium, phosphorus, zinc, copper, iron, manganese and electrolytes like sodium, potassium and chloride were estimated during different phases viz. 0 day (day of oestrus), 11th day (mid luteal phase) and 16th day (early follicular phase) of the oestrus cycle. The mean calcium, copper and zinc concentrations were significantly lower in repeat breeders. There was no significant difference in iron, manganese, sodium, potassium and chloride levels between normal and repeat breeding buffaloes during all the phases of oestrus cycle. It may be concluded that the altered mineral profile may predispose the buffaloes to repeat breeding.
