Abstract
The invention discloses a method for improving local sows to form a novel maternal line by means of American Berkshire. The method mainly comprises the steps that hybridization is conducted by taking a local optimized sow as a female parent and taking a Fujian Huai pig as a male parent, a synthetic line is bred, feeding management is conducted by multiple stages in the breeding process, and the synthetic line serves as a complete set line female parent; hybridization is conducted by taking the American Berkshire as a complete set line first male parent and taking the complete set line female parent as a female parent to obtain complete set line parent generation sows. Compared with the prior art, the method for improving the local sows to form the novel maternal line by means of the American Berkshire has the following advantages that the Fujian Huai pigs are utilized for improving disease resistance and adaptability to feed of the local pigs, local effective forage resources can be fully utilized by the Fujian Huai pigs, feeding management is conducted on the Fujian Huai pigs in the whole growth stage, and the high-quality complete set line female parent is obtained; the American Berkshire is utilized for improving the complete set line female parent, and a complete set line parent generation female parent is obtained; the farrowing survival rate is increased, stress resistance is high, the stable performance characteristic is achieved, and the economic benefit is significant.
Description
Technical field
The invention belongs to technical field of agricultural breeding, be specifically related to a kind of utilize the local sow of U.S. Berkshire improvement to form the most maternal method.
Background technology
Anhui topography and geomorphology is various, the Changjiang river, Huaihe River is run through, there is the Huaibei, Yangze river and Huai river, the Nature district, the south of the River three, there is Dabie Mountain on main mountain range, Mount Huang, Jiuhuashan, Tianzhushan, gas and warm damp and hot, make a clear distinction between the four seasons, due to natural multiformity, therefore local pig resource the most relatively horn of plenty, wherein north, Anhui pig interindividual variation is bigger, hair color is completely black, also there is part flower pig, build is medium, produce pig poor-performing, nest litter size is only about 11.5, and individual weight, growing and fattening performance and carcass trait compare other areas, Anhui certain gap, in order to optimize the growth of local pig, it maternal is improved.
The advantages such as Chinese scholartree pig has resistance to coarse grain, disease resistance is good, meat is excellent, precocious easily fertilizer.
Summary of the invention
It is an object of the invention to for existing problem, it is provided that a kind of utilize the local sow of U.S. Berkshire improvement to form the most maternal method.
The present invention is achieved by the following technical solutions: a kind of utilizes the local sow of U.S. Berkshire improvement to form the most maternal method, comprises the following steps:
