What are the factors affecting cattle fertility

(1) Genetic factors

This is the main factor affecting the reproductive rate of livestock. Fertility varies greatly among different breeds, strains and families.

(2) Nutritional factors

Insufficient nutrients such as daily metabolizable energy, crude protein and vitamins not only affect the normal growth and development of young cows, but also delay sexual maturity and the appropriate breeding age.

(3) Environmental factors

In hot summer, the conception rate of cows after breeding decreases.

(4) Factors of frozen semen quality and insemination technique

Poor semen quality not only affects the conception rate of cows, but also easily causes reproductive diseases in cows. The level of insemination technique is an important factor affecting the reproductive rate; improper timing of insemination for cows in estrus will also affect the conception rate.

(5) Disease factors

Diseases of the reproductive system directly affect normal reproductive function.
