Spring is the golden season of rabbit breeding, and spring females have a strong appetite, high fertility rates, and more litter size, and the survival rate of puppies is high and growth is rapid. In order to allow the female rabbit to produce a few more fetuses in the spring and increase the number of litters and parity times throughout the year, the following points should be made for the spring breeder.

1. Strictly selected

During the seed selection process, high-yield rabbit offspring that have high production performance, good motherhood, and good reproductive performance are selected as the breeding rabbit. The rabbits selected for breeding must meet the characteristics of this breed. The coat should be pure and the genitals should develop well. Specific performance: male rabbit uniform body weight more than 3.5 kilograms, large and round head, four limbs thick, coat length is appropriate in 1.6 cm, no coarse hair, large testicles and drooping, sexual desire, strong sperm vitality, density. The female rabbit has a large belly and a large number of nipples. There are 4 or more pairs of nipples. There are no genital diseases, and the coat length is 1.5 cm. The maternal is good, the lactating ability is strong, and the litter size is much. The male and female rabbits that are not suitable for seeding must be eliminated in time.

2. Scientific feeding

The body condition of the rabbit should not be fat or thin, the female rabbit should maintain a medium sensation, and the male rabbit should maintain a medium-high sensation. At the same time, the feed should be diversified. At the same time when feeding full-grain pellet feed, add green feed, especially carrots. In the 10 days before breeding, 50-100 grams of carrots are fed every day, and the female estrus rate can be increased by 40%-50%. Long-term feeding can increase the lactation of female rabbits and the survival rate of pups.

3. Increase movement and lighting

Exercise can promote the metabolism of female rabbits, increase appetite, and increase resistance to disease. More exposure to the sun, promote the body's vitamin synthesis and absorption of calcium and phosphorus, reduce the rabbit's empty arms and stillbirth, increase the rate of birth of the female rabbit. If the lack of light, female oestrum estrus rate of only 20% -30%; if the increase of light every night 4-6 hours, 7 days after the estrus rate can reach 70% -80%. Therefore, the duration of light should be increased to promote female oestrus.

4. Scientific breeding

First of all, it is necessary to prevent inbreeding. When mating, it is necessary to understand the female estrus cycle. Generally, the female estrus cycle is 7-15 days, and the estrus duration is 1-3 days. If the female rabbit is found running in a cage, loss of appetite, frequent urination, genital flushing, swelling, moist, increased mucus secretion, indicating that the female rabbit has estrus. However, it is necessary to master the changes of the genitalia: "Pink early, Black later, and Dahong time". This means that when the genital area is red, the rate of mating is the highest, and the number of litters is the highest. Therefore, breeding at this time should be selected. Secondly, the scientific breeding method, that is, the repeated breeding method, can increase the fertility rate and the number of litters. The method is a female rabbit estrus mating, successively mating with two male rabbits, or mating female rabbits and a male rabbit first mating, 6-8 hours after the second mating with another male rabbit.

5. Check your pregnancy

There are two ways to check: First, the compound method. The female rabbits were mated 7-8 days later for compounding. The specific operation is to put female rabbits after mating into rabbit cages. If the female rabbits refuse to mate, they run around and issue a squeak to indicate that the female rabbit is pregnant. If the female rabbits receive mating, they will The rabbit is not pregnant and can be bred according to changes in heat. The second is to touch the tire law. About 12 days after the mating of the female rabbit, the fetus is hand-tested to determine if she is pregnant. The specific operation is to grasp the rabbit's ear and neck with one hand, and put the other hand in a figure eight shape under the abdomen of the female rabbit, and gently grope from front to back. If there is no conception, the abdomen is soft as cotton; if it is affected, a string of meatballs like soybeans can be touched on the left and right upper side of the lower abdomen, and it is soft and elastic, and after 15 days it can be touched by several linked peanuts. Meat ball. When touching the tire, the action should be light to prevent miscarriage and stillbirth.

6. Prevent abortion

After the female rabbit is pregnant, do not feed it with mouldy feed. The rabbit house should be kept clean and quiet, do not feed sewage, and do not catch and move the female rabbits at will, reducing the influence of various stress factors. When the pregnant female rabbit is ill, treatment should be taken orally. Try not to inject a needle to prevent miscarriage.

7. Postpartum care

The female rabbit has thirst after delivery and should provide enough brown sugar water and light salt water to prevent the female rabbit from swallowing the pups due to thirst. For unprimed female rabbits, it is necessary to help pull the hair and pull off the hair around the nipple, which is good for breast milk secretion and breast feeding. To prevent the occurrence of mastitis in the female rabbits, oral administration of sulfamethoxazole tablets once a day on the second day of postpartum was carried out for two days, or intramuscular injection of 400,000 international units of penicillin for two consecutive days.

8. Nursing puppies

The pups should eat colostrum in 4-6 hours postpartum. Colostrum is rich in nutrients and also contains immunoglobulin, which can promote the growth and development of young rabbits. When the female rabbit is far more calving and lacks milk, it is necessary to adjust the young rabbit in time, and the part of the litter with multiple litters and the female with insufficient breast milk is fostered to female rabbits with good breast milk and few litters. If there are no foster females, small and some male puppies will be eliminated. If necessary, artificial breastfeeding can also be performed.

9. Pay attention to insulation

The weather in spring is changeable, and it is necessary to pay attention to the heat preservation of the rabbit house. It is advisable to keep the temperature of the rabbit house above 10° C. to prevent the rabbits from frostbite or freezing. Requirements in the 3-5 days before delivery, litter box should be added to the litter box, the female rabbit does not pull the hair after delivery to artificially pull the hair, and cover the hair on the puppies, can play a role in cold insulation.

10. Prevent diseases

In the spring, a large number of pathogenic microorganisms grow and multiply, spread rapidly, and spread widely, which can easily cause various diseases. Therefore, we must do a good job in rabbit house hygiene and regular disinfection. Feeding the female rabbits with garlic, onions, and leeks often can play a bactericidal action to prevent the occurrence of gastroenteritis.
