In lactating animals, the majority of factors like nutrient intake, physiological health, housing management and atmospheric conditions affect reproductive performance of the animal. In dairy animals the main factor affecting reproduction is nutrition status that too trace minerals. So to have a good return from the livestock trace minerals with balanced feeding of the animals must be done. Optimum feeding of minerals with respect to the various stages of reproductive life cycle must be done to increase the reproductive performance.
Hence, present research trial was carried out at the Dairy farm of Banaras Hindu University, Dist. Varanasi (Uttar Pradesh).24 Crossbred (Sahiwal × HF) non-cyclic, non-pregnant cattle, ranging 3-6 years of age wererandomly selected to assess the role of trace minerals in fertility of infertile cows.
It is observed from the study, total 24 infertile crossbred cows were selected to induce oestrus taken forcorrection of anoestrosity with incorporated minerals. Total 8 out of 24 animals exhibited oestrus symptoms after the treatment. Among the animals received incorporated mineral (treatment group) 50% showed the oestrus symptoms. Among the animalsunder control 16.66% came into heat.
