Embodiment 1

[0053] Take the following steps to carry out the cross-breeding of meat rabbits: (1) select the New Zealand white rabbit (obtained from Shandong Haorui Animal Husbandry) as the male parent, and the California rabbit (obtained from Shandong Haorui Animal Husbandry) as the female parent, and carry out artificial insemination, Obtain hybrid generation G1; (2) select the female rabbit of the hybrid generation G1 obtained in step (1) as the female parent, and the flower giant rabbit (obtained from Shandong Fujita Breeding Rabbit Breeding Base) as the male parent, carry out artificial insemination, and obtain the hybrid second generation Generation G2; (3) backcross the second-generation hybrid G2 obtained in step (2) with New Zealand white rabbits to obtain the third-generation hybrid G3; (4) select high-quality meat rabbits from the third-generation hybrid G3 obtained in step (3) for cross-crossing After crossing and fixing, high-generation hybrid meat rabbits were obtained.

Embodiment 2

[0056] Repeat Example 1, the difference from Example 1 is that enterococcus 1.5 × 10 7 cfu / g feed and Lactobacillus 1.0×10 7 cfu / g feed.

[0057] The meat rabbits obtained by the cross-breeding method of the above-mentioned embodiment have fully absorbed the advantages of the three kinds of rabbits. Feed requirements are also significantly reduced, reducing feeding costs. In addition, the study also found that the use of the additive compound represented by formula (I) can reduce the stillbirth rate by 66% (based on the average results of 50 rabbits). In addition, embodiment 2 is compared with embodiment 1, adds enterococcus and lactobacillus in feed, can make feed meat ratio increase to 4.1:1 from 4.8:1, and young rabbit survival rate improves to 94% by 89% ( Based on mean results of 205 rabbits).

Abstract

The invention provides a meat rabbit breeding method. The meat rabbit breeding method comprises the following steps: (1) selecting a New Zealand white rabbit as a male parent and a California rabbit as a female parent, and carrying out artificial insemination to obtain a first-filial generation G1; (2) selecting a female rabbit of the first filial generation G1 obtained in the step (1) as a femaleparent and a chekered giant rabbit as a male parent, and carrying out artificial insemination to obtain a second-filial generation G2; (3) backcrossing the hybridized second-filial generation G2 obtained in the step (2) with a New Zealand white rabbit to obtain a hybridized third-filial generation G3; and (4) selecting high-quality meat rabbits from the third-filial generation G3 obtained in thestep (3), and performing cross fixation to obtain high-generation hybrid meat rabbits. The new variety has the advantages of three rabbits, is high in growth speed, high in meat yield, delicious in meat, obviously enhanced in epidemic disease resistance and low in feed requirement, and the feeding cost can be reduced.

Description

technical field [0001] The invention belongs to a breeding method of animal husbandry, in particular to a meat rabbit breeding method, and more particularly to a meat rabbit breeding method for meat and skin which are selected and bred from different high economic value rabbits. Background technique [0002] Meat rabbits are special economic animals. Many countries and regions use meat rabbits as a source of protein food, and the proportion of meat rabbit breeding is very high. my country is a big rabbit-raising country in the world, and the number of meat rabbits is relatively large, and the perennial stock is in the forefront of the world. In recent years, domestic rabbit breed breeding and genetic breeding have made significant progress. Improving the production level of meat rabbits and increasing economic benefits are issues of common concern to the global rabbit industry. With the development of my country's economy and the improvement of people's diet, genetic improv...
