specific Embodiment

[0061] A total of 5 hybrid combinations were set up in the hybridization test: Huaimei pig synthetic line (HM), Piba pig synthetic line (PB), Bahuaimei pig matching line (B×HM), Pihuaimei pig matching line (P×HM) , Sumei pig matching line (PB×HM). 10 litters were randomly prepared for each hybrid combination, and 1 piglet was selected from each litter, and 50 test pigs were selected for the test of mating.

[0062] Table 2 shows the effects of different hybrid combinations on pig reproductive performance. It can be seen from Table 2 that the number of primiparous piglets, the number of litters at the age of 21 and the litter weight at 21 days in the P×B group were significantly lower than those of other hybrid combinations, and the number of primiparous piglets, The number of piglets after farrowing and litter weight at 21 days were higher than that of control group P; the number of first-parried piglets, number of piglets after farrowing and litter weight at 21 days of age i...

Abstract

The invention discloses a breeding method of a quaternary hybrid Sumei pig (a name of a hybrid pig) complete set line. The breeding method mainly comprises the following steps of breeding basic populations of Meishan pigs and Suhuai pigs with excellent reproductive performance and meat quality; breeding basic populations of Berkshire pigs and Pietrain pigs with excellent growth performance and slaughtering performance; hybridizing Meishan sows and Suhuai boars to cultivate Huai-Mei synthetic lines, and breeding Huai-Mei pigs with excellent reproductive performance and meat quality as parentalgeneration pigs of the complete set line; hybridizing Berkshire sows and Pietrain boars to cultivate a Pietrain-Berkshire synthetic line, and breeding Pietrain-Berkshire pigs with excellent growth performance and slaughtering performance as parental pigs of the complete set line; and hybridizing the parental Huai-Mei sows with the parental Pietrain-Berkshire boars to obtain the Sumei pig completeset commercial pig. The Sumei pig complete set line cultured by the method is black in whole coat hair, has the hybridization advantages of high reproductive performance and fresh and tender meat of domestic local pigs, also has the hybridization advantages of high growth performance and high lean meat percentage of foreign pigs, is tender and fragrant in meat, high in productivity and high in market competitiveness, and improves the pig raising production efficiency.

Description

technical field [0001] The invention relates to a method for cultivating a four-element hybrid Sumei pig matching line. Background technique [0002] my country is a big pig raising country, and pork is also the largest meat consumer product in my country. In my country's large-scale pig production, "Du Dachang" Yang Sanyuan hybrid commercial pigs have an absolute advantage. my country's pig breeding system and pig breed quality have always lagged behind foreign countries with advanced pig breeding. my country's large-scale pig breeding mainly relies on the introduction of foreign pig breeds , there has been an unfavorable situation that the entire breeding pig production is controlled by others. Faced with this situation, we are forced to use domestic and foreign pig breed resources to cultivate domestic characteristic pig breed strains and breeding systems with excellent performance. [0003] With the improvement of living standards in our country, citizens have higher an...
