Six ways to improve the reproductive ability of small rabbits

2018-04-01 00:00:14

The best breeding time of rabbits is the middle and late estrus. In addition, there is also a timely problem on the day of breeding, early and late breeding in summer is better, and noon breeding in winter is appropriate. Is there any way to improve the reproductive ability of rabbits? Let's talk about it.

Methods/Steps
1

First, strengthen seed selection

2

Choose healthy and disease-free female rabbits with strong sexual desire, good maternal sex and good reproductive organ development. It is best to select from 3 to 5 litters of good female rabbits. The most suitable breeding age for domestic rabbits is generally 1 to 3 years old, and the rest should not be used for breeding except for individual excellent breeds of rabbits above 3 years old.

Second, strengthen the feeding principle

4

Provide full price diet to meet the nutritional needs of breeding rabbits to reduce embryo death and abortion and improve breeding rabbit fertility. The sudden sound in daily theory is easy to cause panic among rabbits, which can lead to abortion of pregnant female rabbits or a decrease in female rabbit libido.

Third, pay attention to timely breeding

6

According to the heat preservation and cooling facilities and local climate conditions, the breeding season and mating time are arranged. Practice shows that the temperature of the rabbit house is generally controlled above 10℃, and the appropriate temperature is 15 ~ 25℃. Therefore, the pregnancy rate and litter number of female rabbits are the highest in spring and autumn.

The best time to breed is the middle and late estrus. In addition, there is also a timely problem on the day of breeding, early and late breeding in summer is better, and noon breeding in winter is appropriate.

Fourth, improve the breeding method

9

Female rabbits are irritant ovulatory animals, which are ovulated after mating stimulation of male rabbits, so they should be rematched once after the first mating interval of 8 to 10 hours, that is, repeated mating. A female rabbit is mated with two male rabbits continuously, and the interval between them is not more than 20 to 30 minutes, which is called double breeding. The fertilization rate of female rabbits increased by 10% ~ 20% and the litter size increased by 1 ~ 3 by repeated or double breeding. In addition, for the female rabbit who is not in estrus or refuses to match for a long time, the number of contacts with male rabbits can be increased, and the female rabbit sex hormone secretion can be induced by chasing and climbing the hip stimulation, and the chance of pregnancy can be improved.

Fifth, improve the reproductive intensity

11

When the breeding condition is good and the female rabbit is very strong, the breeding intensity can be improved by frequent breeding or semi-frequent breeding, and more commercial meat rabbits can be produced to improve economic benefits. It is generally believed that intensive breeding can be implemented for commercial rabbits, and it is not suitable for breeding rabbits. Semi-frequency dense breeding means that the female rabbit is mated within 12 to 15 days after delivery, which can shorten the breeding interval by 8 to 10 days, and increase the breeding of 3 to 4 babies per year.

6. Prevent disease

13

Strengthen health and epidemic prevention measures in rabbit houses to prevent disease. Clean the rabbit house often, observe the rabbit group frequently, after the occurrence of disease, the sick rabbit immediately isolation treatment.
