What to Do About Dairy Cow Infertility? Identifying the Key Contributing Factors Is Essential

What to do about infertility in dairy farming? What factors influence it?

Dairy cow infertility refers collectively to a cow failing to conceive after 3 services postpartum and to a long period postpartum during which she cannot be bred. Infertility is not a disease caused by a single factor; it is a clinical composite response of the cow's body brought about by the influence of various different causes. The factors that give rise to infertility mainly include congenital abnormalities of the reproductive organs, feeding and management factors, endocrine disorders, diseases of the reproductive organs, and certain infectious diseases, among others. Therefore, the prevention and treatment of dairy cow infertility should adopt different technical measures according to the specific condition of the affected cow. In dairy production practice, feeding and management, reproductive management, and the occurrence of infectious diseases such as brucellosis are the most common causes of dairy cow infertility.

For infertility caused by feeding and management, a balanced ration should be supplied and stress reduced. The supply of the ration must be ensured, the cow's appetite and feed intake improved, and an adequate supply of protein, minerals and trace elements guaranteed.

For infertility caused by diseases of the reproductive organs, the feeding and management of cows during the perinatal period should be strengthened to prevent the occurrence of postpartum diseases. The calving pen must be kept clean and hygienic and obstetric assistance must be hygienic and scientific; when diseases of the birth canal occur they should be treated promptly to prevent serious illness from affecting the cow's normal estrus and breeding. For cows that do not come into estrus, the cause must be identified and dealt with promptly. At the same time, semen quality and good insemination technique must be ensured to prevent missed breedings, so that breeding is carried out promptly and accurately.

When examination reveals that a dairy cow has anestrus and infertility caused by factors such as reduced ovarian function, ovarian cysts, or persistent corpus luteum, combined treatment with hormones and antibiotics may be adopted. Reduced ovarian function and ovarian cysts in dairy cows can be treated with drugs such as luteinizing hormone and progesterone. Persistent corpus luteum in dairy cows can be treated with drugs such as prostaglandin and estradiol. Dairy farms should maintain strict epidemic prevention and quarantine systems to strictly guard against the occurrence of infectious diseases such as brucellosis.
