Reproductive dysfunction is a common, long-standing and difficult problem to solve in the dairy industry. Dairy cows are significantly higher than other cows and the proportion is as high as 15 to 20%. In addition to genital tract diseases such as uterine inflammation, due to human, physiological factors are: 1, implicit estrus implicit estrus common in cows of all ages, accounting for about 13%. The factors affecting recessive estrus are the results of combined effects such as lack of exercise (fatigue), high temperature, malnutrition, inheritance, and unobserved and improper identification. However, in production practice, most of the hidden estruss of high-yielding dairy cows occur. As the high-yield cows suppress the secretion of estrogen with the increase of milk production, resulting in estrus is not obvious, resulting in not easy to observe and missed, some to obtain higher milk production, in the first estrus after birth, artificial unworthy, often As a result of multiple recombinations, the first estrus breeding at 42 to 60 days after delivery is the key to improving the conception rate and determining the amount of life-long milk production. 2, ovarian static motility This type of cows are mostly young cows with poor nutritional status, poor body condition, lack of exercise, rectal examination of uterine atrophy, both sides of the ovary is small, no corpus luteum. The main measures are to strengthen the husbandry and management, provide comprehensive nutrition, and restore the body condition. In particular, it is necessary to ensure that the cows have a certain amount of quality dried barley every day. Drug treatment can be placed vaginal warts containing progesterone, 10 to 16 days after the withdrawal, that is, injection of pregnant horse serum. Regulates reproductive function of organs such as the ovary through hormone regulation. Irregular estrus intervals between 17 days or more than 24 days are considered to be irregular, except that oestrus and ovarian cysts are not observed due to heat, mainly due to excessive estrogen secretion. Can be placed to contain progesterone vaginal fistula, inhibition of estrogen secretion or intramuscular injection of gonadotropin-releasing hormone, estrus occurs 18 to 23 days, breeding. In the actual production, due to dystocia, postpartum treatment caused by birth canal infections, endometritis and uterine empyema and other diseases, resulting in long-term infertility or persistent corpus luteum, can be applied 25 mg prostaglandin F2a, melt the corpus luteum, relax the uterus, promote Uterine contents are excreted, combined with
Antibiotics and Chinese herbal medicine symptomatic treatment, to avoid uterine flushing as much as possible to prevent secondary peritonitis.
