What if the cow does not estrus and is infertile? How to deal with cows without estrus
At present, the price of cattle on the market is OK, and if the cows are farmed, the state also has subsidies, but despite this, there are not many cattle farmers who are willing to raise cows. This has led to the steady growth of cows in recent years. The embarrassing situation before. Raising and breeding cows is not only costly and has a long cycle, but also various problems are easy to occur during the breeding process. If the problem is serious, you can't wait for the calf to live for a long time, which is why you are not willing to raise cows. Today, Xiaobian will introduce to you the three problems that are easy to occur in breeding cows and how to deal with them. I hope that the majority of cattle-raising friends can help. 1, long time no estrus If the heifer reaches the initial age or the adult cow does not estrus for a long time after birth, it will increase the breeding cycle and feeding cost, which in turn will affect the benefit output of the cattle. Under normal circumstances, heifers can develop estrus at 12 months of age. At the latest, they will not exceed 18 months of age. Once they have not developed estrus for more than 18 months, they will be asked to check the ovarian development if the ovaries are incomplete. It needs to be eliminated. If the ovarian development is normal, other problems should be considered, such as malnutrition or overnutrition. In the absence of other problems, pregnant horse serum gonadotropin can be injected to induce estrus and promote ovulation. The estrus can occur within 3 months after birth, and it will not exceed 6 months at the latest. If there is no estrus for more than 6 months, it is necessary to find the cause, such as uterine inflammation, malnutrition, overnutrition and traces. Lack of elements, etc. Cows suffering from uterine inflammation often have odorous mucus effluent. In this case, it is necessary to use drugs for uterine flushing. For example, 500 ml of normal saline is added to ceftiofur sodium 0.5 g once a day for 3 days. Cow postpartum Lactating calves need to consume a lot of nutrients. If the nutrition in the diet can not meet their lactation needs, it will affect the estrus. This can increase the nutritional supply of postpartum cows, and feed the calves in advance and weaning in advance. Cows have excess nutrients in the case of house feeding and feeding. The diet is rich in nutrients and the amount of exercise is insufficient. Cows will develop obesity and affect estrus and ovulation. Cows with no inflammation and moderate estrus can be estrus. To consider the lack of trace elements, when cows lack selenium and vitamin E, they may delay estrus, pay attention to the supplement of various trace elements and vitamins. After the cows are not estrus, after symptomatic treatment, it is necessary to inject pregnant horse serum gonadotropin to induce estrus and promote ovulation. 2, cows often match infertility Cows with infertility must first consider the bull problem, timing of breeding and breeding methods, etc., after eliminating these problems, the cows themselves have problems, such as excessive cow age, uterine inflammation, follicular cysts, delayed ovulation or no Ovulation, persistent corpus luteum, etc. If the cow is too old, it should be eliminated as soon as possible. It can be injected with progesterone or pregnant horse serum gonadotropin for trial treatment; uterine inflammation requires uterine flushing and anti-inflammatory, which is no longer cumbersome; follicular cyst, ovulation delay or no ovulation can be Through rectal examination, it can be injected with progesterone or pregnant horse serum gonadotropin for treatment; persistent corpus luteum will continue to secrete progesterone, inhibit follicular development, so that the estrous cycle stops and infertility, can be injected with prostaglandins or cloprostenene Alcohol is treated. 3, vaginal or uterine prolapse Vaginal or uterine prolapse is also a common problem in cows. There are many causes of the disease. One cow is too early, two cows are too large, three cows are over-nutrition, and four are long-term feeding mold. Feed, five cows are old and frail, six are difficult to produce or miscarriage, and seven have had vaginal or uterine prolapse. In the case of mild symptoms, that is, when a small meat ball is exposed while standing, it can be taken in. It can be treated by reducing feeding, strengthening exercise, forced standing, and adjusting the armpit posture (lower and lower height). ~7 days of treatment, no small meat balls can be exposed when lying down; if the symptoms are severe, the prolapse should be washed with warm water of 0.1% potassium permanganate solution, and then sent to the body for resetting, and It is fixed and anti-inflammatory with pocket suture. At the same time, it is necessary to reduce auxiliary feeding such as feeding, strengthening exercise, forced standing and adjusting posture. After 7~10 days, it is completely fixed and then disassembled. The above is the analysis of the three problems encountered in raising cows. Cows are actually highly productive livestock, but cow farming is indeed costly and has a long cycle. However, if you decide to raise cows, you will encounter the above problems. , you can follow the method described in the small series to solve. Feel good, just like a lot of favorites!
