Uso da ocitocina na produção leiteira; Rentabilidade e produção

Abstract

Oxytocin is a natural hormone found in mammals, its production occurs in the hypothalamus, being stored in the posterior pituitary gland with functions of promoting uterine muscle contractions during childbirth, the ejection of milk during breastfeeding, in addition to helping to expel the placenta. In 1959, synthetic oxytocin was discovered and synthesized, which is now widely available in injectable form for veterinary use. In cattle, the mammary cell is composed of secretory cells is composed of secretory cells and systems of ducts and cisterns, where milk is continuously produced by the secretory cells , organized in alveoli communicating with the ducts and cisterns of the gland and teats. Thus, 20% of the milk is in the teat cisterns and 80% is contained and stored in the alveoli. However, only the milk from the cisterns is available for milking, while the reaming 80% depends on external stimuli such as manual feeling, calf suckling or the use of synthetic oxytocin. Although the body already produces the hormone naturally, its inhibition can occur due to some factors, both physical and external.
