To make female rabbits prosperous and productive, the following measures can be taken:
1. Choose male and female breeding male and female rabbits to be large in size, strong in physique, and strong in males. In particular, male rabbits with normal testes and well-proportioned size should not be used for breeding. The female rabbit needs to have a large body size, good motherhood, strong body, smooth Coat, and more than four pairs of teats. If it is a female rabbit that has been paralyzed, it is necessary to choose a high fertility rate, a high calving rate, a strong lactation force, and a high survival rate of the pups.
2. Stimulate estrus Bring the female rabbit to the male rabbit to cross the mating to stimulate the female rabbit to ovulate. The distinctive feature of rabbits and pigs and cattle is that they cannot ovulate at the same time during estrus, but instead begin ovulation 10 to 12 hours after mating. Without mating stimuli, mature eggs will degenerate and shrink within the ovaries and will not be excreted. When the female rabbits of appropriate age are mated with the animals for a long period of time, degraded and atrophied eggs will accumulate in the ovaries, causing early deterioration of the ovarian function. Late breeding or two breeding times are too long and can cause similar degradation.
3. Popularize advanced breeding techniques 1 Repeated mating methods. According to the characteristics that the female rabbit can ovulate after being stimulated, the same species of male rabbit is used for the second time 7-8 hours after the first mating. This method can improve female fertility and calving rate. 2 double mating method. In the estrus period of the female rabbit, two male rabbits of the same breed are bred, and the first male rabbit is mated for 5 to 10 minutes after mating, and then the second male rabbit is mated. This method can increase the number of ovulation and the choice of fertilized eggs in the female rabbit, increase the calving rate, and enhance the physique and life ability of the pups. 3 blood matching (heat distribution, frequency breeding method). Using the characteristics of estrus and abortion after 1 to 2 days after the calving of the female rabbit, the female rabbit can be mated and can obtain more parity times and multiply rabbits in one feeding period. Using this method, it is required that the rabbit must be weaned 26-28 days in advance. It is best that the rabbits give birth to a “nanny†to feed. The nutrition of the female rabbit must be strengthened. If the temperature of the female rabbit drops significantly, the mating should be stopped next time. To avoid the decline of the female rabbit's physical fitness.
4. Prevention of inbreeding Male and female rabbits with a difference of more than four generations and different bloodlines are used for mating and reproduction. The hybrids of such rabbit breeds are large in size, develop rapidly, have high utilization rate of feed, and have good viability, disease resistance and production performance. Do not mate with males and females that have common ancestors within three generations. This is because the descendants that reproduce in this way often have small body size, weak physique, poor disease resistance, degeneration of production performance, stillbirth, or miscarriage.
5. To strengthen the feeding of pregnant female rabbits According to the female rabbit's physical condition, two methods can be used: 1 For the first time, the female rabbits of the first fetus, from the beginning of pregnancy, gradually feed the concentrate, and the feed is more than that of the female rabbits. 10%-20%. This can ensure the normal development of the fetus and meet the nutritional needs of the female rabbit's own growth and development. 2 The adult female rabbits with better lyrical condition should use green material as the main ingredient in the pre-pregnancy period and 10 to 15 days after pregnancy. The nutrition level during pregnancy should be higher than that of other rabbits to prevent miscarriage or stillbirth due to poor health. .
Using the above two methods, the amount of concentrate feeding should be reduced 3 to 5 days before delivery, and more fresh and juicy green materials should be fed to prevent constipation and mastitis.
