Evaluation of the breeding objectives of pure lines in three-way crossbreeding system of quality meat-type chickens by applying the method of systems analysis

Systems analysis combined with the difference method was used to evaluate the breeding importance of 13 production traits in pure lines of an actual three-way crossing system (Ⅰ×(Ⅱ×Ⅲ)<sub>♀</sub>). The results indicated that the traits with the highest breeding importance were body weigh...

description Systems analysis combined with the difference method was used to evaluate the breeding importance of 13 production traits in pure lines of an actual three-way crossing system (Ⅰ×(Ⅱ×Ⅲ)<sub>♀</sub>). The results indicated that the traits with the highest breeding importance were body weight at 10 wk of age (BW10), feed conversion from birth to 10 wk of age (FCV10) and meat quality assessment score (MS) in the line Ⅰ, MS, FCV10 and egg number (EN) in the line Ⅱ, EN, adult body weight and egg weight in the line Ⅲ. The selection traits in pure lines were determined on the principle of reduced aggregate breeding value. Those should be improved first were BW10 and MS in the line Ⅰ, MS, BW10 and EN in the line Ⅱ, and EN in the line Ⅲ. The conclusions would be helpful to the breeding strategies of the actual crossing system in the future.
