Embodiment 1

[0040] Example 1: Identification of 10,000 10-week-old Hailan brown high-quality young chickens

[0041] 1) Sample collection and requirements

[0042] Randomly collect 30 copies of young chicken blood to ensure the dispersion of the collected chicken blood, separate serum for antibody detection.

[0043] 200 young chickens were randomly selected for weight detection and shank length detection.

[0044] 2) Weight detection and uniformity calculation

[0045] The method of individual weighing was adopted, and the operation was carried out on an empty stomach. The weight standard at the age of 10 weeks was 923g, 122 above the standard and 78 below the standard, and the weight uniformity was 87%.

[0046] 3) Tibia length detection and uniformity calculation

[0047] The 10-week-old shin length standard is 90 mm, 135 above the standard and 65 below the standard, and the uniformity of the shin length is 94%.

Abstract

The invention belongs to the field of young chicken quality identification, and particularly relates to an identification method for high-quality medium-size young laying hen. According to the identification method, conventional indexes and blight indexes are utilized to perform the comprehensive identification of high-quality medium-size young chickens, wherein the conventional indexes for reflecting the development of young chickens are adopted as the basis, and the blight indexes greatly affecting the laying hen production are adopted as the supplementation, such that the identification method is reliable, is mainly used for evaluating the quality of the medium-size young chickens, and can further provide the technical reference for the breeding of the high-quality medium-size young chickens in the young chicken farm.

Description

technical field [0001] The invention relates to the technical field of quality identification of young hens, in particular to a method for identifying high-quality medium-sized young laying hens. Background technique [0002] Segmented breeding of laying hens refers to the professional division of labor in the entire feeding cycle of laying hens. In the brooding, rearing and laying stages, different breeding enterprises or individuals are responsible for the production and operation, and respectively establish special youth chicken farms. And laying hen farms for specialized production. The segmented breeding of laying hens has great advantages in disease prevention and control and economic benefits. This is the advanced laying hen breeding model advocated by our country, and it is also the direction of the large-scale development of the laying hen industry. The segmental feeding of laying hens in my country mainly has three modes: three-stage feeding, two-stage feeding and...
