Embodiment Construction

[0016] 1. Materials and methods

[0017] 1. Test time and place

[0018] This experiment was carried out from April to November 2016 at the Meihuaxing Pig Breeding Farm of Qiangli Animal Husbandry Co., Ltd., Huangmei County.

[0019] 2. Feeding experiment design

[0020] Single-factor design was used to select the descendants of Meihuaxing purebred pigs with clear sources, consistent appearance, normal development, good health, no genetic defects, male and female (about 15kg body weight, castrated male pigs), and Duroc purebred pigs were selected by random sampling method. × Meihuaxing hybrid offspring, Berkshire × Meihuaxing hybrid offspring, 50 pigs each, a total of 150 pigs, divided into three groups (Meimei, Dumei, Bamei), each group has 5 replicates, and each replicate has 10 pigs. pen feeding

Abstract

The invention discloses a hybrid production method capable of increasing the local pig pork production. The method comprises the steps that hybridization is conducted by taking Duroc as a male parentand taking a Meihuaxing pig as a female parent, and Duroc and Meihuaxing cross uni-generation pigs are bred; the result shows that daily gain can be increased, and feed conversion efficiency can be improved; carcass traits are good, the slaughter rate is 71.43+ / -0.99%, the lean meat percentage is 54.57+ / -0.78%, the carcass length is 94.07+ / -2.89 cm, the carcass weight is 72.03+ / -1.39 kg, the eye muscle area is 33.13+ / -2.07 cm<2>, the average backfat thickness is 26.13+ / -0.55 mm, the Duroc and Meihuaxing lean meat percentage is 54.57+ / -0.78% which is increased by 5.8% and 6.4% compared with those of Berkshirea and Meihuaxing and Meihuaxing and Meihuaxing respectively, it is indicated that by taking Duroc as the male parent for hybridization, the meat performance of the Meihuaxing pigs can be improved, the lean meat percentage is increased, the growth rate of the local pigs can be obviously increased, and the time for entering the market can be shortened.

Description

technical field [0001] The present invention relates to the technical field of the hybrid production method of pork, in particular to a hybrid production method that improves local pig pork output. Background technique [0002] Meihuaxing pig is a group of excellent local pigs (Yangxin pig) in Hubei Province. It is produced in the lakeside plains and low hilly areas on both sides of the Yangtze River in southeastern Hubei. The central production areas are in Yangxin County and Huangmei County. It has early sexual maturity. , strong stress resistance, docile temperament, and resistance to rough feeding, etc., and was included in the national species conservation plan in 2014. [0003] With people's attention to safety, health, green and ecological food, pork consumption is also showing a trend of diversification. People not only need "foreign three-yuan" pork with more lean meat, but also require high intramuscular fat content and certain The proportion of local pig blood is...
