Mixed-culture and hybridization method for goats

Abstract

The invention discloses a mixed-culture and hybridization method for goats.The mixed-culture and hybridization method includes the step that a sheep yard is built on mountain land, Boer goats, Mongolian gazelles and local black goats are mixed and bred for a long time, and includes the balance steps that 1, sheep houses are built, wherein at least one unit colony house is built, and a moving area and a sleeping area are arranged in each unit colony house; 2, ryegrass, pasture, mulberries and sorghum are planted in the moving areas of the colony houses; 3, stocking and confining are combined, in spring and autumn, the goats are let out at twelve, and are taken back at seven, in summer, the goats are sent out at three in the afternoon, and are taken back at the dark time, on the rainy day and in winter, confining is carried out, and confining feed is mainly corn, soybeans and a plurality of crops; 4, 1-2 produced lambs need to be separated, and need to be separated and fed for 1 month-2 months and fed in a grouped mode.According to the mixed-culture and hybridization method, Boer goats, Mongolian gazelles and local black goats are mixed and bred on the mountain land, the goats are acclimatized to allow the habits of the goats to be similar, then high-quality and strong goats are hybridized, high-quality descendant goats are cultured, and the survival rate of the goats is increased.

Description

technical field [0001] The invention belongs to the technical field of vertebrate breeding, and in particular relates to a goat hybridization method. Background technique [0002] In the past ten years, due to important reasons such as environmental pollution, severe epidemics, unsound standards of veterinary drugs, feed and food, backward testing methods and equipment, lax supervision, and economic interests in the process of production and distribution, the safety of livestock products has become a threat. People's health and the survival of animal husbandry are serious problems that affect export earnings. In addition to epidemic diseases, various drugs, chemical substances, heavy metals, biological hormone residues and pollution are also increasingly harmful to the hygienic quality of animal products, especially through mad cow disease and bird flu. , Clenbuterol incident, the government will focus on food safety monitoring in formulating industry norms. Since 2006, the ...

AI Technical Summary

Problems solved by technology

[0003] 1. The variety is poor, and the popularity rate of fine breeds is not high. Almost 70% of the farmers are still raising soil sheep. The scale is small and there is basically no environmental protection equipment, which leads to the discharge of sheep excrement and urine waste water. First, it affects water quality. Contains a large amount of organic matter and organisms. When decomposed, it will consume dissolved oxygen in the water, thereby destroying the ecological balance. For example, when the water source of tap water is polluted by sheep excrement and urine wastewater, the water will contain odor, which will affect people's application, such as fish ponds. When the water source is polluted by sheep feces wastewater, the water will become smelly, and the dissolved oxygen in the water will be scarce, making it impossible for fish and shrimp to survive;

[0004] 2. The breeding environment is poor, the housing conditions are poor, and the smell is strong, which leads to the breeding of a large number of mosquitoes, and mosquitoes are the number one killer of sheep disease transmission;

[0005] 3. There is a greater threat of disease;

[0006] 4. The production efficiency is low. The slaughter rate in developed countries has reached over 190%, and the feed-to-meat ratio is 2.5-2.8:1. However, the current slaughter rate in Chongqing is only about 90%, and the feed-to-meat ratio is around 3.2-3.5:1;

[0007] 5. The degree of industrialization is not high
