Embodiment 1

[0013] Slaughter 90-day-old Gushi chickens (or other ages and other breeds) according to the family, measure the intramuscular fat content of the breast or leg meat, and select the intramuscular fat weight content of the breast muscle according to the average intramuscular fat content of the family Families with no less than 0.3% or no less than 1.0% intramuscular fat weight of leg muscles, taking into account both growth rate and egg production, adopt core group breeding method for pure line selection, and use family full sibling or half sibling selection The method is used to select trait indicators, and the comprehensive index method is used to comprehensively evaluate each family, and the family whose comprehensive index value is higher than the average value is selected to keep the seeds and breed the next generation. The commercial generation chicken is produced after the strain is crossed with the common strain. It is determined that the intramuscular fat content of the ...

Embodiment 2

[0015] Sampling and slaughtering 42-day-old pure line of fast large Aviin white broiler chickens according to the family, measuring the intramuscular fat content of breast meat or leg meat, according to the individual intramuscular fat content, the selected breast muscle intramuscular fat content is not less than 0.3% or Individual compatriots with an intramuscular fat weight content of not less than 1.0% in leg muscles. Parents are selected taking into account both growth rate and egg production. The selected parents are used to breed the next generation, and the strains are bred by subbreeding for more than 3 generations. After being crossed with common strains, a commercial generation chicken is obtained, and the intramuscular fat weight content of the breast meat of the commercial generation chicken is determined to be not less than 0.3%, and the intramuscular fat weight content of the drumstick meat is not lower than 1.0%.

Embodiment 3

[0017] From the individuals of the breeding family in Example 1, the breast meat was taken from each individual living body of the 90-day-old chicken, and the intramuscular fat content was measured, and the individual whose breast muscle intramuscular fat weight content was not less than 0.3% was selected, and the growth rate and Egg production, select and retain individuals whose comprehensive index value is higher than the average value, and breed the next generation, so that more than 3 generations of subculture are carried out, and the selected lines are crossed with ordinary lines to produce commercial generation chickens. The weight content of the intramuscular fat in the commercial generation chicken breast is determined to be not less than 0.3%, and the weight content of the intramuscular fat in the chicken leg meat is not lower than 1.0%.

Abstract

The broiler breeding process features the selection of parents to be hybridized with the intramuscular fat content of breast chicken or leg chicken as main characteristic while considering also the growth speed and egg laying amount. In the same time, the individuals are supplementarily molecule mark selected early based on the genotype of inosinic acid molecular mark of fatty acid-binding protein. The method of the present invention can breed excellent broiler variety with powerful marketing competitive power and makes it possible for famous local Chinese chicken variety to enter international market.

Description

【Technical field】 [0001] The invention relates to a poultry breeding method, in particular to a breeding method for improving broiler quality. 【Background technique】 [0002] The improvement and improvement of meat quality has become one of the leading directions of broiler breeding today. In the past two decades, broiler breeding has been focusing on production performance such as growth rate and reproductive performance, as well as commercial traits such as feather color and skin color. In actual breeding, the consideration of meat quality mainly focuses on the selection of breeding materials, which is mostly judged by the blood relationship of local chicken breeds in the matching line, and high-quality indicators are not included in the selection plan. For example, the Chinese patent application announcement number is the broiler breeding supporting technology recorded in the patent application publication document CN1135282. The result of this selection is likely to cau...
