Effect Of Stress on Cattle Reproduction

Stress has been reported to influence the animal reproduction adversely. The impact of stress on reproduction depends on the type of stress, genetic predisposition of the animals, timing and duration of the stress. It inhibits GnRH/gonadotropin secretion in hypothalamus-pituitary-adrenal (HPA) axis through secretion of Adrenocorticotropin (ACTH), glucocorticoids (GH) and catecholamine (CA). With a better understanding of the basic biology and altered physiological processes involved in stress adaptability, it would be possible to devise strategies for animal welfare and optimal production.
