Raising the breeding power of donkeys is fundamentally to ensure that breeding male and female donkeys maintain a strong fertility and maintain a good breeding condition. From the management point of view, it is to pay attention to increase the donation rate of female donkeys as much as possible, and prevent the female donkey from Infertility and miscarriage prevent difficult labor; technically speaking, it is necessary to increase the conception rate. First, the breeding female donkey should maintain a strong fertility from the first breeding of the female donkey, with the increase in parity and age and fertility increased year by year, to the strongest fertility at the age of. Regardless of the male and female donkeys, when the nutrients are good, they can be bred to be over 20 years old, so there is the saying that “the old donkey is less cowâ€. Poor nutrition to 15 to 16 years old loses its fertility. In the breeding herd, attention should be paid to asses that often retain 65% to 70% of their fertile period. Second, the breeding donkey group should maintain a good body condition. The breeding male and female donkeys have to go through system selection to achieve good reproductive performance, physical fitness, and the nutritional status is middle and superior. For this reason, breeding male and female donkeys must be fed according to feeding standards, with good quality forage, full price concentrates, adequate salt, and sufficient drinking water. Third, to improve the female donkey's rate of mating female donkey is an important part of increasing fertility. The measures are as follows. Fourth, raising the female donkey's conception rate to increase female donkey fertility rate is an important part of improving fecundity. The measures are as follows. Steroids are a class of lipid soluble hormones. In the maintenance of life, regulating sexual function, body development, immune regulation, skin disease treatment and birth control has obvious effect. Steroid hormones are mainly used for: anti-inflammatory and anti-allergic; Treatment of male and female diseases and contraception; Improve metabolic function. Major side effects: more significant damage to the liver, and female masculinity. Long-term or a large number of use will appear acne, hairy, atrophic lines, purpura, osteoporosis, femoral head necrosis. steroids side effects,steroids bodybuilding,buy steroids,steroids benefits.steroids bodybuilding Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptidenootropics.com
First, adjust the herd structure and increase the proportion of breeding female donkeys so that the proportion of breeding female donkeys in the herd reaches 50% to 70%.
Second, a reasonable layout, the establishment of a donkey breeding website, the implementation of artificial insemination, so that as many female donkeys participate in breeding.
Third, increase rejuvenation and promote estrus. Insufficient fodder, monoculture of old forage grass is not full price, especially the lack of protein and vitamins, is the main reason for raising the female donkey without estrus. To this end, the female donkey must increase the fine material one month before mating; participate in labor to extend the female donkey's intake time, and reduce the amount of exercise for the poorly bred, and increase the green and juicy feed.
Fourth, strengthen estrus observation and establish a reporting system. The breeder should be familiar with the estrus law and individual characteristics of each female donkey, observe the performance of the female asses in estrus, and once discovered, promptly lead to the artificial insemination station for estrus identification. Estrus forecasts can also be made based on the last estrus date to prevent missed matches.
Fifth, to speed up the uterus to restore the old, prompting maternal ass mating. The uterus of the female donkey after the delivery and the time of re-estrus after childbirth is an important sign to determine the reproductive function of the female donkey. Donkeys and horses, like about 10 days after birth (first episode), can be “matchedâ€, and each estrus has normal estrus, and if it can be bred in time, it can increase the overall fertility rate of the herd.
Sixth, adopt a method of concentrated trial and breeding. In the season of high seasoning, villagers are selected as the unit to conduct routine trials on the female donkey. If the female donkey is found to be estrus, it will be immediately mobilized. This can improve the utilization of the excellent male donkey and improve the quality of the donkey.
Seventh, timely examination and treatment of estrus mother donkeys. Among the female donkeys used for service, 10% to 15% of female donkeys that are not estrus due to reproductive tract diseases should be promptly diagnosed and treated. Female donkeys that have lost reproductive ability should be excluded from the number of appropriate female donkeys.
The first is to improve feeding management and maintain the proper sex of the female donkey. The worse the nutritional condition of a donkey or a female donkey, the more weight they lose and the lower their fertility. The main effect of malnutrition on young female donkeys is to delay the time to reach a certain weight, postpone the age of the initial period, and greatly reduce the rate of conception of the virgin female donkey. Undernutrition also has a great influence on the re-pregnancy of the female donkey. It shows that the post-partum weight loss is greater, and as a result, the fertility rate of the mating is affected. Sometimes pregnancy also causes miscarriage and stillbirth, resulting in a decrease in reproduction rates. 2. The greatest effect of nutrient deficiency during female gestation is often the weight loss and reproduction of the female donkey.
