- Abstract
Stress is a strong barrier to dairy animal reproduction and, hence, poses an alarming threat to combat it. The economic sustainability of a dairy herd mainly depends on getting utmost reproductive efficiency. In contrast to extensive research on infectious diseases, nutrition, infertility etc. less is known about animal welfare and its interaction on reproductive efficiency. Animal welfare means paying attention to animal's social relation, environment, climate and availability of adlib food and water. Welfare is a condition in which animals do not feel a mental or physical discomfort and do not feel stress or pain. A loss of welfare brings the animals into stress, which affects their production and reproduction. The natural, physical and environmental factors affecting animals are air temperature, relative humidity, solar radiation, atmospheric pressure and wind speed. Summer stress reduces productive and reproductive efficiency of dairy animal. The neuroendocrine mechanism of heat stress has been extensively reviewed. Heat stress compromises hypothalamic GnRH secretion, and circulating concentration of LH and FSH reduces. In addition, there is also evidence that HS affects follicular dynamics and ovulation.
