Problems solved by technology

[0004] The mutton sheep supplied in the market are often because the breeder pursues the weight of the mutton sheep, the breeding period is short, the fat is thick, and the taste is affected. The reason is that the breeding and feeding methods are not ideal

Embodiment Construction

[0020] Embodiments of the invention are described in detail as follows:

[0021] A method for hybrid breeding of Dorper sheep based on agricultural economy, comprising the following steps:

[0022] 1) The black-headed Dorper sheep were used as the male parent of the first generation, and the local small-tailed Han sheep was used as the female parent of the first generation. After the multi-lamb test was carried out on the female parent, artificial insemination was carried out to obtain the first generation of hybrid f1,

[0023] 2) taking the black-headed Dorper sheep as the second-generation male parent, and using the first-generation hybrid f1 obtained in step 1) as the second-generation female parent, and performing cross-breeding to obtain the second-generation hybrid f2, and carrying out the multi-lamb test;

[0024] 3) take the black-headed Dorper sheep as the male parent of the third generation, and use the second-generation hybrid f2 obtained in step 2) as the female p...

Abstract

The invention discloses a Dorper sheep hybridization breeding method based on agricultural economy. The method includes the steps that 1, with a black-head Dorper sheep as the first-generation male parent and a local small-tail Han sheep as the first-generation female parent, prolificacy testing is conducted on the female parent, and then artificial insemination is conducted to obtain a first filial generation f1; 2, with the black-head Dorper sheep as the second-generation male parent and the first filial generation f1 obtained in step 1 as the second-generation female parent, hybridization is conducted to obtain a second filial generation f2, and prolificacy testing is conducted; 3, with the black-head Dorper sheep as the third-generation male parent and the second filial generation f2 obtained in step 2 as the third-generation female parent, hybridization is conducted to obtain a third filial generation f3, and prolificacy testing is conducted; 4, high-quality sheep are selected from the third filial generation f3 obtained in step 3 for hybrid mating and parent consolidation to obtain hybrid sheep. The Dorper sheep hybridization breeding method has the advantages that with the black-head Dorper sheep as the male parent and the small-tail Han sheep as the female parent, progressive purification is conducted three times, and then hybrid mating and parent consolidation are conducted, so that the variety advantages of the black-head Dorper sheep are maintained; by adopting microbiologically-treated straw compound mixed concentrate, the feed cost is greatly reduced.

Description

technical field [0001] The invention relates to a breeding method for animal husbandry, in particular to a method for cross-breeding Dorper sheep based on agricultural economy. Background technique [0002] Dorper sheep, native to South Africa, is a crossbreeding of horned Dorset sheep and Persian black-headed sheep. It is a world-renowned breed of meat sheep. The top of the head is straight, the length is moderate, the forehead is wide, the bridge of the nose is slightly protruding, there are no horns or small horn roots, the ears are small and straight, neither short nor wide. The neck is thick and short, the shoulders are broad and thick, the back is straight, the ribs are arched, the chest is plump, and the hindquarters are muscular. The limbs are strong and of moderate length, and the limbs are correct. When the feed protein is sufficient, the Dorper sheep do not need to be sheared, because its hair can fall off freely. Dorper lambs grow rapidly and have a large weani...
