- Abstract
This study aims to conduct the performance test on residual feed consumption (RFC) traits in the 11th generation of Better Feed Efficiency Brown Tsaiya (BFEBT) and its control line for continuous improvement on feed conversion ratio in BFEBT. The feed consumption, egg mass, body weight at the start and end of the test period of individual ducks were recorded from 34 to 37 weeks of age to calculate RFC. The average of feed consumption, egg mass, and feed conversion ratio in BFEBT were 3,384 g, 1,637 g and 2.09, respectively, while those in the control line were 3,850 g, 1,755 g, and 2.23, respectively. Compared with the previous generation, the feed consumption and feed conversion ratio in BFEBT were almost the same, and the performances were better than in the control line; the egg production increased slightly than the 10th generation, but still slightly lower than the control line. The phenotypic value of RFC of the 11th generation of BFEBT and its control line was -116.5 g and 165.6 g, respectively, the difference between the two lines was slightly less than the previous generation. In the near future, a genetic selection index, taking both feed efficiency and egg production traits into account, will be established based on the above results to promote sustainable management of BFEBT.
