The ewe does not let the ram climb across, mainly means that the ewe does not estrus. We can use: Wangqing Taibao upgrade, which can solve the problem of ewes not estrus and not letting rams climb across. Next, let's talk about the reasons why the ewes do not let the rams climb across, mainly the following three points:
There are many reasons why ewes do not come into heat, mainly including the following aspects:
1. Nutritional factors
1. Nutritional deficiencies:
Vitamin deficiency: Ewes cannot synthesize certain vitamins on their own, such as vitamin A, and must be ingested through feed. Captive ewes with silage and hay as the main feed for a long time are prone to vitamin A deficiency due to single feed, which in turn affects estrus. Vitamin A deficiency can lead to estrus and lamb neurological symptoms and even blindness in ewes. We can give ewes to use: multivitamin Taibao, so that the effect of supplementing vitamins and other nutrients is very good.
2. Lack of trace elements: the lack of trace elements such as zinc and manganese is also one of the reasons why ewes do not estrus. Zinc deficiency will cause ewes to have symptoms such as estrus, abortion, fetal malformations, etc., while manganese deficiency will lead to ewes not estrus, no sexual desire, infertility and other problems.
3. Excess or insufficient nutrition:
Too thin: The ewe is malnourished and the body is too thin, which will cause the follicles to develop to a certain time and shrink, and even form a persistent corpus luteum, causing infertility.
Obesity: In order to pursue the fat of sheep, farmers give too much concentrate feed or concentrated feed, resulting in fat accumulation in ewes, which will also affect the development of follicles, resulting in no estrus.
2. Management factors
Insufficient exercise: The captive method limits the amount of exercise of the ewes, and the lack of exercise will affect the physical health and estrus of the ewes. Preparing a large playground for the sheep to ensure that the sheep have enough exercise can help promote estrus.
Management errors: such as overuse of production, noisy feeding environment, crowding or the presence of other stressors, etc., can lead to the ewes not coming into heat.
3. Disease factors
Endocrine disorders: The reproductive performance of ewes is directly regulated by endocrine function. Endocrine dysfunction, such as insufficient estrogen secretion, hypothyroidism, aging, ovarian insufficiency, etc., will directly or indirectly affect the reproductive ability of ewes, resulting in estrus or infertility.
Uterine inflammation: Ewes are not well cared for during pregnancy, and postpartum care is not in place, which will cause uterine infection and inflammation, which will affect estrus.
In the process of ewe breeding, you can use: Ewe Taibao, which can regulate the reproductive system of ewes, improve the health of ewes, and avoid problems such as ewes not estrus and unmatched.
To sum up, the reasons why ewes do not come into heat involve many aspects such as nutrition, management, disease and age. In the process of breeding, it is necessary to comprehensively consider these factors and take corresponding measures to ensure the normal estrus and reproduction of ewes. For example, regularly check the nutritional status of ewes, strengthen feeding management, provide sufficient space for exercise, and treat diseases in a timely manner.
