Key Focuses in Rabbit Blood Typing Technique: A Compreh

Section 1: How to Appropriately Utilize the Rabbit Blood Matching Technique

The rabbit blood matching technique requires high standards across various aspects, which are closely related to the rabbit's natural breeding capabilities, age at breeding, nutritional status, season, and breeding techniques.

Part 1: Determining the Initial Breeding Age of Rabbits

1. The initial breeding age of rabbits should be determined based on their weight and age. Generally, under normal conditions of饲养 management, rabbits reach maturity and are ready for breeding when they reach a certain age and their weight is 70% of the standard weight for their breed. This indicates that the rabbits are sufficiently mature for breeding and reproduction.

However, in actual production scenarios, the standard for suitable breeding age varies among different body types of rabbits. Compared to females, male rabbits reach sexual maturity later, so the initial breeding age for males is typically about a month later than for females. To prevent early breeding or inbreeding, rabbits should be kept in separate pens before they reach sexual maturity.

2. Determining the breeding lifespan of breeding rabbits and updating the rabbit population in a timely manner.

The breeding lifespan of breeding rabbits is generally 3 years. However, if rabbits are robust and utilized effectively, their breeding lifespan can be extended appropriately. On the other hand, if breeding rabbits are too old, or if they have low fertility, low litter size, and low survival rate of offspring, they should be culled and the population updated promptly. It is generally recommended to replace the breeding population every two years.

Part 2: Mastering the Rabbit Breeding Process Correctly

1. Regularly inspect the health of breeding males and provide an appropriate living environment.

Before breeding, the keeper should conduct a thorough check of the breeding males. If any breeding male is found to be weak or sick, they should not be allowed to participate in mating. If possible, the semen quality of breeding males can also be checked.

2. Timely introduce the female rabbits for breeding.

During the estrus period, healthy and suitable female rabbits should be promptly placed in the breeding male's pen for mating. It is important to avoid placing the male in the female's pen, as this can disrupt the rabbits' sexual activity and lead to breeding failure.

3. Postmating procedures

After mating, the female rabbit should be immediately removed from the male's pen, gently tapped on the buttocks to prevent semen from escaping, and then returned to the female pen. Additionally, breeding records should be kept promptly.

Part 3: Timely Rebreeding

To prevent pseudopregnancy in female rabbits and ensure pregnancy, the keeper needs to check the pregnancy status of the female rabbits promptly and allow those that have not become pregnant to rebreed. There are generally two types of rebreeding for female rabbits:

1. Repeated breeding:

After the first mating, the female rabbit is rebred with the same male rabbit 6 to 8 hours later. Studies have shown that the fertility rate of repeated breeding can reach 95% to 100%.

2. Double breeding:

After the first mating, the female rabbit is bred with another male rabbit 10 minutes later. Relevant studies have shown that the fertility rate of rabbits using double breeding technology is 25% to 30% higher than that of single breeding rabbits. However, this breeding method is only suitable for commercial rabbit production, as it determines the lineage of the offspring.

These are the key points that the Rabbit Blood Matching Technique, as illustrated by Rabbit Doctor, needs to focus on. We hope this information can be helpful to you.
