Acquired infertility and symptomatic infertility. This is one of the most common, such as females suffering from chronic endometritis, ovarian incompetence and atrophy, ovarian cysts, persistent corpus luteum, vaginitis, and the occurrence of fetal decomposing abortion. In addition, some medical and surgical diseases can also cause infertility. Second, nutritional infertility. Maternal animals are overweight or overweight, poor feed quality, and lack of certain minerals and vitamins. Third, the use of infertility. Excessive employment, too much milk in the mother's stock, etc. Fourth, climate infertility. Maternal long-term feeding, lack of sunshine.
Congenital infertility includes interspecific hybridization, hermaphroditism (fetal and male genitalia on one carcass), metamorphosis of female (female on appearance but complete male genitalia), congenital reproductive tract abnormalities ( Single uterus or no uterine cavity, no ovaries, closed cervix, no cervix, double cervix, two cervix excisions, excessive vaginal valve development, etc.).
Aging infertility The infertility of livestock is old during the old age period. Generally, the mare is 17 to 25 years old, the cow is 15 to 20 years old, the ewe is 6 to 9 years old, and the pig is 6 to 8 years old. Individuals who have had early terminations of fertility may be pathological.
Infertility is caused by artificially infertile maternal stocks that are not suitable for ovulation (premature or late), ovulation examinations are not performed prior to mating, and breeding of sires by females after breeding several times a day may result in infertility.
