The main points of breeding rabbits for different purposes are as follows:
1. Meat rabbits
1. Weight requirements
The growth rate of meat rabbits should be fast. Generally, 70-day-old meat rabbits with a body weight of 2-2.5kg are selected for introduction.
2. High feed conversion rate
The level of feed conversion rate of meat rabbits is an important indicator to measure the quality of meat rabbits. Generally, the higher the feed conversion rate of meat rabbits, the better Up to (2.8 ~ 3.2): 1, it means that the quality is better.
3. Other properties
① Conception rate: the conception rate of excellent breeding rabbits should be above 85%;
② Litter size: excellent breeding rabbits The average litter size of rabbits is more than 6 to 8;
③ Survival rate: The survival rate of weaned rabbits with excellent breeding should be above 80%.
In addition, the requirements and standards for the introduction of breeding rabbits should also take into account various performance indicators such as slaughter rate and meat yield.
2. Hair Rabbit
1. Hair production performance
① Hair production Quantity: Taking the 73-day hair-raising period as the period, the shearing quantity of the 5-month-old rabbit is multiplied by 5, and the hair yield of the fine-bred rabbit should not be less than 1kg.
② Coat density: Generally, the fur density of fur rabbits can be checked by hand grasping and mouth blowing. If the fur of the rabbit is thick and uniform, and the skin cannot be blown from the mouth, it means that the fur is dense.
③ Coat length: The hair of a fine rabbit should grow about 1mm a day, and in 30 days, the hair of a rabbit should grow about 3cm.
④ Coat uniformity: The coat
of each part of the fine breed rabbit should be uniform throughout the body.
2. Hair type
The hair of the long-haired rabbit should be white, soft and thick. The rough hair content of the introduced rabbit is preferably 15% to 20%.
3. Body shape
Good body shape is a main criterion for measuring a good long-haired rabbit. A good long-haired rabbit generally needs to meet the requirements of large body shape, full arms, front and rear. The trunk is strong and compact, the chest is wide and deep, the back is straight and the waist is straight, and the appearance is majestic.
4. Good adaptability
The introduction of long-haired rabbits should meet the requirements of long breeding time, wide distribution area and good adaptability. It is best not to introduce varieties that are in the experimental stage.
Three, Rex Rabbit
1, Coat Color
The coat color of Rex Rabbit must match the breed The characteristics remain the same, and the coat color must be pure. If the hair is mixed, it should not be used as a seed.
2. Coat Quality
① Short: The ideal length of the Rex rabbit’s coat is 1.6-1.8cm. If the rex rabbit’s hair exceeds 2.2cm, it should not be used as an improved breed.
② Flat: The coat length of the Rex rabbit should be the same, the whole body fur should be neat and uniform, and the surface should be flat. If the number of gun hair is large, or the suede is prominent, it should not be introduced.
③ Fine: The cross-sectional diameter of the finger hair fibers of the excellent Rex rabbits is small, the number of gun hairs is small, and the number of gun hairs accounts for 4% to 7% of the total hair; The average fineness is 16 to 19 microns. If the values of the Rex Rabbit’s hair are inconsistent with these, it should not be introduced.
④ Dense: The fur of an excellent Rex rabbit must be dense, with a density of more than 16,000 to 38,000 hairs per square centimeter.
⑤ Fast: The fine hair of Rex rabbits is not easy to fall off, and the board is tough.
3. Weight
The weight of a Rex rabbit directly affects the area of its fur. Generally speaking, a good Rex rabbit should weigh more than 3.5kg in adulthood.
The above are some of the criteria for selecting and introducing breeding rabbits that I have introduced to you, and I hope to give you a reference direction for introduction. In addition, when introducing breeding rabbits, it is also necessary to check the health status of the rabbits to ensure that the rabbits meet the requirements of their breeds and are in good physical condition.
