Although rabbit breeding has no obvious seasonality, it can breed all year round, but the differences in temperature, sunshine and nutritional status in different seasons have certain effects on the estrus, conception, litter size and survival rate of the female rabbit. Impact. To this end, it is very important to rationally arrange the breeding and breeding of rabbits in the four seasons. First, strengthen the selection work Choose a female rabbit that is healthy, disease-free, has strong sexual desire, good maternality, and good reproductive organs. It is best to keep the rabbits from the 3 to 5 fetuses of the fine female rabbits. The most suitable breeding age for rabbits is 1 to 3 years old. Except for some excellent rabbits, it is not suitable for other species. Second, strengthen feeding management Supply full-price diets to meet the nutritional needs of rabbits to reduce embryonic death and miscarriage and increase rabbit fertility. Sudden sounds in daily management can easily cause panic in the rabbit group, which can lead to abortion of pregnant female rabbits or decreased sexual desire of female rabbits. Third, pay attention to timely breeding According to the heat preservation and cooling facilities and local climatic conditions, the breeding season and mating time are arranged. Practice has shown that the temperature of the rabbit house is generally above 10 °C, and the suitable temperature is 15-25 °C. Therefore, the female rabbits have the highest conception rate and the highest number of litters in spring and autumn. The best breeding time is in the middle and late stages of estrus. In addition, there is a timely problem on the day of breeding. It is better to breed in the early morning and evening in summer, and it is better to mix in the winter at noon. Fourth, improve breeding methods Female rabbits are irritating ovulation animals, which are ovulated after stimulation by male rabbits. Therefore, they should be compounded once every 8 to 10 hours after the first breeding, that is, repeated breeding. A female rabbit is continually mated with two male rabbits, and the interval between them is no more than 20 to 30 minutes. This is called double breeding. The use of repeated breeding or double breeding can increase the conception rate of female rabbits by 10% to 20%, and the number of litters will increase by one to three. In addition, the female rabbits who have not estrus or refused to match for a long time can increase the number of contacts with the male rabbits, and stimulate the secretion of sex hormones in the female rabbits by chasing and crawling, thereby improving the chance of conception. Fifth, improve the reproductive intensity Breeding and management conditions are good. When the female rabbit is very strong, it can increase the reproductive intensity by frequent breeding or semi-frequency breeding, and produce more commercial meat rabbits to improve economic benefits. It is generally believed that intensive breeding can be carried out on commercial rabbits, and it is not suitable for breeding rabbits. Semi-frequency breeding means that the female rabbits are bred within 12 to 15 days after delivery, which can shorten the breeding interval by 8 to 10 days, and increase the reproduction of 3 to 4 births per year. Six, prevent disease from happening Strengthen the sanitation and epidemic prevention measures in the rabbit house to prevent the disease from happening. I often clean the rabbit house and observe the rabbit group. After the disease occurs, the sick rabbit is immediately isolated and treated.
