Embodiment Construction

[0033] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0034] The present invention selects 60 120-day-old Baicheng oil chickens (black feathers), half male and half female, detects the second exon polymorphism of H-FABP and the content of intramuscular fat (IMF) in the breast muscle, and analyzes (minimum Square method) the relationship between the two.

Abstract

The invention discloses a preparation method and application of a genetic marker of a high intramuscular fat content in Baicheng fatty chicken. The preparation method comprises the following steps of selecting 30 Baicheng fatty cocks with black feathers and at the age of 120 days and 30 Baicheng fatty hens with black feathers and at the age of 120 days; detecting polymorphism of a second exon of H-FABP and the content of intramuscular fat (IMF) in the pectoralis; and analyzing the relation between the polymorphism of the second exon of the H-FABP and the content of the intramuscular fat in the pectoralis. An experiment shows that the prepared genetic marker selects the Baicheng fatty chicken with the high intramuscular fat content in the pectoralis.

Description

technical field [0001] The invention belongs to the technical field of poultry genetic markers, and relates to a preparation method and application of a genetic marker for high intramuscular fat content in the breast muscle of Baicheng oil chicken, in particular to a high intramuscular fat content in the breast muscle of Baicheng oil chicken (black feather). Preparation and application of genetic markers for fat content. Background technique [0002] With the improvement of people's living standards, there are stricter requirements on the quality and taste of meat. Chicken is the main meat on the table, and the quality of chicken has increasingly become the focus of attention. Most of the standards for measuring the quality of chicken meat come from people's taste, and there is no unified standard at present. After analysis, the high intramuscular fat IMF in chicken is considered to be a main indicator affecting the meat quality traits of chicken and improving the tendernes...
