Rabbits are small, productive, grass-eating livestock and have the highest fertility in livestock. The fertility of female rabbits is directly related to the level of production and the economic efficiency. How can we improve fertility in breeding female rabbits? We can start from the following major aspects.
(1) Strengthen the selection of female rabbits that are healthy, disease-free, sexually active, well-bred, and well-developed reproductive organs. It is advisable to keep the breeding pups selected from 3 to 5 of the excellent females, and the nipples should be more than 4 pairs. Pups that have fewer litters, low conception rates, poor maternity, and poor lactation performance cannot be used for breeding. Rabbits are generally the most suitable reproductive age is 1 to 3 years old, 3 years old and above except for some excellent rabbits, the rest should not be used for seeding.
(B) to strengthen the rearing and management of seed selection must pay attention to before and after the breeding management, to provide full-priced diet, to meet the nutritional needs of rabbits to reduce embryonic death and miscarriage, increase breeding ability of rabbits. The long-term feeding of a single feed or the lack of certain nutrients, or overnutrition can lead to over-fertilization of the breeding female rabbit, which will reduce its fertility.
Improper management will not only significantly reduce the fertility of breeding rabbits, but also cause serious infertility. Sudden sounds in daily management can easily cause panic in rabbits, leading to miscarriage in pregnant female rabbits or decreased libido in female rabbits.
(3) Pay attention to timely mating According to the heat preservation and cooling facilities and the local climatic conditions, arrange the mating season and mating time. For example, winter and winter must provide more green feed, do a good job of cold and warm work. In order to ensure that the female rabbit is strong in physique, it is generally possible to reproduce 1 to 2 fetuses in places where conditions permit. Controlling the temperature in rabbit houses in winter and early spring is the fundamental guarantee for normal rabbit breeding. Practice has shown that the general rabbithouse temperature is controlled above 10°C, and the suitable temperature is between 15°C and 25°C. In spring and autumn, the female rabbit has the highest fertility rate and the largest litter size.
The best breeding time is in the middle and late stages of estrus. At this time, the female rabbit's pus is moist, swollen, and mostly red, and mating is easy to become pregnant. Premature and late seeding results are unsatisfactory. There is also a timely issue on the day of breeding. In the summer, it is better to be seeded in the early morning and late in the evening, and in the winter, it is appropriate to breed at noon. Because at this time, the temperature is relatively suitable, rabbit spirit is better.
(IV) Improving breeding methods Ovulation stimulating ovulatory animals in female rabbits are ovulated after male rabbits have been stimulated by mating. Therefore, they should be reconstituted at intervals of 8 to 10 hours after the first breeding. The purpose of the first mating is to stimulate the ovulation of the female rabbit. The purpose of the second mating is formal fertilization, which can increase the fertility rate and the number of litters of the female rabbit. The best time for breeding is around 8:00 and 17:00. A female rabbit is mated with two male rabbits continuously. The interval between them is no more than 20-30 minutes. This is called double mating. Repeated mating or double mating can increase female fertility by 10% to 20% and increase litter size by 1 to 3 eggs. In addition, for females that have not been estrus or refuse to use for a long time, the method of attracting emotions can be used, that is, increase The frequency of contact with male rabbits induces sex hormone secretion in the female rabbit by chasing and crawling to stimulate the chance of abortion.
(5) Raising the breeding intensity The feeding and management conditions are better. When the female rabbit is very strong, the breeding intensity can be increased by frequent breeding or semi-frequent breeding, and more commercial rabbits can be produced to increase the economic benefits. This is a hot spot for meat rabbit breeders all over the world. Frequent breeding often results from short maturation time due to farrowing. Therefore, this breed is commonly known as “blood matchingâ€. Foreign female rabbits are mated for 1.5 to 2 days after childbirth. Three days after weaning 28 days, another litter was born. However, it is generally believed that intensive breeding can be carried out for commercial rabbits, and that it is not appropriate for breeding rabbits to produce too close. Semi-frequent reproduction means that female rabbits are mated within 12 to 15 days after childbirth, which can shorten the breeding interval by 8 to 10 days and increase reproduction by 3 to 4 births per year.
(6) Preventing the occurrence of diseases The fertility of female rabbits is easily implicated in the disease. It is necessary to strengthen the epidemic prevention measures in rabbit houses to prevent the occurrence of colds, rickets, and Pasteurella spp. The rabbits are frequently cleaned and the rabbits are observed. After the disease has occurred, the rabbits are immediately isolated.
