Most farms now use artificial insemination technology, which can greatly improve the fertilization rate of cows and improve the economic benefits of farms. However, some cows have infertility after artificial insemination. What is the reason? How to solve cow infertility?
Cow reproduction is a complex physiological process that is influenced by many factors, including: genetic factors (such as genetic defects), nutritional factors (lack of vitamins), age factors (aging), management factors (poor health), environmental factors (high temperature) , poor environment in the cattle house) and disease. If any of the factors in the middle are affected or fail to meet the requirements, it will directly affect the cow's pregnancy and eventually cause economic losses.
Main factors affecting cow infertility
1. Congenital infertility: abnormal or developmental malformations of the reproductive organs caused by congenital or hereditary factors.
2. Nutritional infertility: caused by insufficient nutrition, overnutrition, vitamin deficiency and mineral deficiency.
3. Management infertility: Infertility can be caused by the lack of exercise, long lactation period, poor sanitary conditions, improper feeding and management methods, and unsuitable external environment.
4. Aging infertility: cows' old reproductive organs shrink and reproductive function declines.
5. Disease infertility: improper postpartum care, abortion, uterus caused by stillbirth and leading inflammation, suffering from diseases such as fallopian tubes, ovaries, parasites, brucellosis, tuberculosis and other diseases can cause cow infertility.
6. Weaning on time: If the feeding time is delayed, it is not only unfavorable for the development of the digestive organs (stomach is underdeveloped, affecting Zengyi), but also increases the cost and affects the reproductive ability of the cows.
solution
1. Congenital infertility and aging infertile cows should be eliminated in time.
2. Nutritional infertility: strengthen supplement feeding, provide sufficient nutrients for young cows (young cattle: corn silage and straw 1:1, limited feeding, head feeding rough feed 4-6kg, concentrate 2.5) 3kg → corn 42%, bran 30%, soybean meal 10%, flax cake 15%, bone meal 2%, salt 1%) 2 times a day, 12 hours apart, daily drinking water 2 times - 3 times, salt 2 times - 3 Times).
3. Deworming: timely diagnosis, using deworming drugs to deworm on time.
4. Ensure the environmental safety of the pens: timely clean the house, disinfect regularly, and do a good job of ventilation.
5. Disease infertility: Flush the uterus with normal saline and antibiotics before insemination, and then 5% iodine in the uterus (observe the next estrus, if not recovered, then lose again)
6. According to the actual production rules of cows, the general feeding period is set at 90 days. The feeding program uses the amount of milk in the early stage, and the feeding is less in the later stage, and the coarse feed is fed more.
The above is the analysis of the reasons for cow artificial insemination and infertility, and I hope to help you!
