How to improve the litter size of female rabbits?

Provide a reasonable and rich diet

There is not a breeder who doesn't want his mother rabbit to have a high yield and live a high life. The litter size and survival rate of female rabbits are directly related to their economic benefits. How to do this needs to be constantly summarized in the feeding process from master to slave. Generally speaking, diet, living environment and mother rabbit care will affect the litter size of mother rabbits. In addition to the first time, preventing diseases is also a very crucial step. If the mother rabbit gets sick during pregnancy, there is a great chance of miscarriage.

First, the choice of breeding rabbits must be cautious.

Breeding rabbits have normal reproductive organs, strong sexual desire, pure coat color, strong physique and bright eyes. The mother rabbit is very maternal, with more than 4 pairs of nipples. The ratio of male to female rabbits is 1: 4 ~ 5.

Second, feeding in the preparation period.

Feed rich in protein and vitamins is provided for breeding rabbits before feeding, which is diversified, palatable and easy to digest. Feed it twice a day, once in the morning and once in the evening, provide enough clean drinking water, add a little salt in summer and drink warm water in winter to keep the breeding rabbits moderately fat.

Third, scientific breeding and conception.

The first mating age of rabbits is 4 ~ 5 months, that of middle rabbits is 5 ~ 6 months and that of big rabbits is 7 ~ 8 months. Spring and autumn are the best mating time. Double-line reproduction can be carried out, and the offspring are suitable for commercial rabbits; Repeated breeding can also be carried out, and the same male rabbit can be used again 6-8 hours after the first breeding, and the offspring can choose to keep the seeds for later use.

Select excellent breeding rabbits.

Fourth, artificially induce ovulation for them.

Follicle-stimulating hormone or triple hormone can be injected into muscle at the rate of 0.5 ~ 1 ml each time, and mating can be carried out after 4 ~ 6 hours. Female rabbits can also be stimulated by inducing estrus, smelling estrus and massaging their genitals.

Fifth, check the mother rabbit in time to prevent empty-mindedness.

1. compound method: the female rabbit is put into the male rabbit cage 5 ~ 6 days after mating, and if she refuses to mate, she is pregnant.

2. Fetal touching method: On the 8th ~10 day after mating, the female rabbit touched the peanut-sized meatball from front to bottom and became pregnant. If it is found that the mother rabbit is not pregnant, it should be urged to breed in time.

Fifth, strengthen the management of female rabbits.

The average gestation period of female rabbits is 30 ~ 3 1 day. 7 ~ 8 hours before labor, pluck the hair and hold the grass to make a nest. The mother rabbit gives birth in the early morning or at noon, so it is necessary to prepare for the litter box and delivery. The primiparous female rabbit should be cared for by a special person during delivery. Those who have not given birth for more than 60 minutes should be assisted manually to facilitate delivery and ensure the safety of mother and baby.

Old and frail breeding rabbits should be eliminated in time

6. Female rabbits should pay special attention to feeding during pregnancy and lactation.

The nutritional level of pregnant rabbits is slightly higher than that of empty pregnant rabbits. In the later stage, beans, bone meal, fish meal and other feeds are supplemented, and each rabbit has 50-70g per day. Before lactation/0/5 days, fish meal and other high-quality feed were supplemented, and each rabbit was supplemented with green feed/0/~/0.5 kg and concentrate 50 ~/0/00 g every day. Female rabbits are fed soybean milk and brown sugar water when they are short of milk. Don't feed moldy materials and keep the rabbit house quiet.

Seven, to ensure that young rabbits can eat enough breast milk.

Young rabbits are not only rich in nutrition, but also have a lot of antibodies, which can ensure that young rabbits are protected from external bacteria during this period. When 15 years old, they should start feeding supplements and take 0. 15% licorice water in time (every 100 ml contains10g brown sugar water,10.05g glucose and dijunjing). Rabbits aged from 35 to 42 days can be weaned. Regularly feed chlorpheniramine and other drugs to prevent coccidiosis.

Eight, for the old and weak rabbits should be eliminated in time.

The quality of breeding rabbits is very important to young rabbits, so it is necessary to eliminate the weak and old breeding rabbits in time. If the breeding rabbits are too old, not only will the success rate of breeding be greatly reduced, but it will also do a lot of harm to the breeding rabbits themselves. Therefore, it is better to replace the breeding rabbits in time and be strong.
