Cross breeding method for new-American-line boars and new-Canadian-line sows

Abstract

The invention relates to a breeding method for new strain piglets, in particular to a cross breeding method for new-American-line boars and new-Canadian-line sows. By conducting cross breeding between the new-American-line boars and the new-Canadian-line sows for three generations, third-generation cross-bred piglets are obtained, and the third-generation cross-bred piglets are improved new-Canadian-line piglets. The improved new-Canadian-line piglets have advantages of being rapid in growth rate, high in fecundity and adaptability, and meanwhile, the meat of the piglets tastes delicious, delicate and mellow, and the economic value and the feeding value are ensured.

Description

technical field [0001] The invention relates to a breeding method of a new strain of piglets, in particular to a hybrid breeding method of a Xinmei boar and a Xinjia sow. Background technique [0002] The development of pig breeding industry is not only a strategic task of agricultural industrial structure adjustment, but also a major measure to improve consumption structure and improve people's health level. With the development of my country's economy and the improvement of people's living standards, the proportion of meat consumer goods in people's lives is also increasing, and pork consumption accounts for more than 60% of meat consumer goods. When people consume pork, not only the "quantity" has increased, but also higher requirements for "quality", paying more attention to nutritious and safe meat, and at the same time paying more and more attention to the flavor of meat [0003] my country is a traditional pig producing country in the world, and almost half of the pi...

Problems solved by technology

However, due to technical problems in breeding, the quality of pork in the Chinese market is still at a relatively poor level, while high-quality lean pork mainly relies on imports, and the breeding of improved varieties is in a bad cycle of "introduction-maintenance-degradation-reintroduction"
