Donkeys have lower fertility than other livestock, which is related to their own physiological characteristics and obvious seasonality. Therefore, there are many factors that affect the breeding of donkeys, such as heredity, environment, nutrition, breeding management, breeding time and breeding techniques. To improve the breeding capacity of donkeys, we must grasp the following aspects:
Breeding Female Donkeys to Maintain Vigorous Fertility
From the initial breeding of female donkeys, its fecundity increased year by year with the increase of parity and age, and the fertility was strongest at the time of its infancy. No matter if male or female donkeys, when they have good nutrition, they can grow to be over 20 years old; while those with poor nutrition can only use 15 to 16 years old and lose their fertility. In breeding herds, 65% to 70% of female donkeys must enter the period of vigorous growth.
Breeding donkeys should maintain a good body condition. Reproduction of male and female donkeys requires strict selection, good reproductive performance, physical fitness, and superior nutritional status. It is supplied with high quality grass, ingredients and plenty of water.
Increase female donkey acceptance rate
1. Adjust the donkey structure and increase the proportion of breeding females and donkeys so that the ratio of breeding females to herds reaches 65% to 70%.
2. To rationalize the layout, establish a donkey breeding and breeding website, carry out artificial insemination, and more female donkeys.
3. Increase rejuvenation and promote estrus. Grass, material is not a single, full price diet. Especially before and during the breeding period, nutrition must be strengthened.
4. Strengthen estrus observation and establish a timely reporting system. Look for estrus to ensure that it does not miss out.
5. Breast-feeding mother donkey, accelerate the uterine involution, promote early allocation, and strive to provide blood stasis 7 days to 10 days after delivery.
6. Take a concentrated approach to trials and breeding methods. After estrus, do a good job in timing and breeding, and make full use of the male donkey resources.
7. Timely examination and treatment of female asses without estrus, female asses without treatment value are eliminated in time.
Improve female donkey's conception rate
1. Strengthen feeding and management, maintain moderate lyrical (70% to 80%), feed nutrition should be comprehensive and balanced.
2. The quality of the semen's semen must be high and must meet the standards. 3 timely timely insemination, mating, to accurately grasp the estrus identification, master insemination time, skilled in insemination technology.
4. Follow the operating procedures and pay attention to hygiene. Artificial insemination should be performed strictly and aseptically to prevent the female donkey from infecting the reproductive system.
5. The implementation of early pregnancy examination, pay close attention to compounding.
Prevent female infertility and abortion
The female donkey often suffers from infertility due to reproductive obstacles. It often accounts for more than 40% of the female donkey and causes great losses to the female donkey. Abortion is another factor that affects the proliferation of female donkeys, accounting for about 5% or more. Therefore, prevention of reproductive diseases should be strengthened and improper feeding and management, as well as abortion and infertility.
Improve the survival rate of donkeys
1. Do a good job of consignment work and manage the new life of donkeys.
2. Pay attention to keep warm, prevent thunder, especially when sudden changes in climate.
3. It is very important for the donkey's constitution and survival to improve the donkey's consumptiveness.
4. The lactation of the female donkey is very important for the survival and development of the young, especially the first 3 months of the lactation month.
5. Feed the donkey's beak as early as possible, and begin to attract food one week after birth, giving soft, easily digestible grass and materials, gradually increasing grass and material quantity as weight increases. It is better to feed a single donkey.
