Problems solved by technology

However, the traditional Sichuan white rabbit is small in size and slow in growth rate. It weighs only 1.25kg at the age of 3 months and only 2.76kg as an adult, which seriously affects the development effect. It is far from meeting the needs of the market, and it is difficult to carry out large-scale breeding and promotion.
German White Rabbit is a strain in the Zika line. It serves as the male parent of the female line in the line. It has the advantages of fast growth and good reproductive performance. However, it has poor adaptability to the southwest region and poor continuous production performance. High, which also limits its promotion and utilization

Embodiment 1

[0025] The breeding method of a kind of endemic stress-resistant meat rabbit new strain of the present embodiment comprises the following steps:

[0026] (1) 15 German synthetic white rabbits with fast early growth and strong adaptability were selected as male parents, and 60 Sichuan white rabbits with strong stress resistance, obvious estrus, easy mating, high blood nest mating rate, and good breeding performance were selected. As the female parent, hybridization is carried out, and each female rabbit produces 3 to 4 litters, and the F1 generation hybrid population is obtained;

[0027] (2) In the F1 generation, 120 female rabbits with strong disease resistance and obvious estrus were selected for backcrossing with 30 male German synthetic white rabbits, and each female rabbit produced 3~4 litters to obtain the F2 generation hybrid population;

[0028] (3) Three selections were carried out on the male and female rabbits in F2. At weaning, select individuals with more than 5 l...

Embodiment 2

[0035] Other content is as in embodiment 1, control temperature below 28 ℃, humidity below 70%.

[0036] The effect is the same as in Example 1, but the stress resistance to high temperature is slightly lower.

Embodiment 3

[0038] Other content is as the content in embodiment 1, and the cultivation method of a kind of endemic stress-resistant meat rabbit new strain of the present embodiment comprises the following steps:

[0039] (1) 15 German synthetic white rabbits with fast early growth and strong adaptability were selected as male parents, and 60 Sichuan white rabbits with strong stress resistance, obvious estrus, easy mating, high blood nest mating rate, and good breeding performance were selected. As the female parent, hybridization is carried out, and each female rabbit produces 3 to 4 litters, and the F1 generation hybrid population is obtained;

[0040] (2) In the F1 generation, 120 female rabbits with strong disease resistance and obvious estrus were selected for backcrossing with 30 male German synthetic white rabbits, and each female rabbit produced 3~4 litters to obtain the F2 generation hybrid population;

[0041] (3) In the F2 generation, 30 male rabbits with strong stress resistan...

Abstract

The invention belongs to the technical field of culture and particularly relates to a method for breeding a new local stress-resistant meat rabbit species. According to the method, Sichuan white rabbits and German synthetic white rabbits are taken as breeding materials, and the new local stress-resistant meat rabbit species is bred through a grading hybridization method. The new meat rabbit species bred through the method has the advantages of the Sichuan white rabbits and the advantages of the German synthetic white rabbits and is strong in stress resistance, and the fattening survival rate reaches over 98%; bucks are strong in sexual desire and high in semen quality; does are obvious in estrus and easy in mating, the blood-nest mating pregnancy ratio reaches up to 82%, the number of annual production births is over 7-8 under the condition of artificially-assisted mating, the continuous production performance is good, and the new meat rabbit species has very strong adaptability to the climate environment and culture characteristics of the southwest of China.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a method for cultivating new strains of endemic stress-resistant meat rabbits. Background technique [0002] my country is the largest rabbit-raising country in the world, and the southwest region is the most important production and consumption area of ​​meat rabbits in my country. The annual slaughter volume and consumption account for more than 40% and 50% of the country's total respectively. In the past 30 years, the meat rabbit industry in Southwest China has developed rapidly. A large number of fast and large meat rabbit breeds and supporting lines have been introduced from abroad, which has greatly improved the production efficiency of rabbits. The growth rate of meat rabbits has increased from an average of more than ten grams per day to More than 30 grams, greatly shortening the market age of commercial rabbits. However, due to the control of the great-gran...
