主 题:Korean native duck performance carcass yield meat quality.
摘 要:This study was carried out to investigate the growth performance, carcass yield and meat quality of large-type Korean native ducks (KND). A total of 420 day-old ducklings were divided into four treatments (seven replicates/treatment, 15 birds/replicate) by strains (A and B) and gender (male and female) in a 2 × 2 factorial arrangement under complete randomized design. The body weight (BW) of female KND was higher at week 2 and for male it was higher in week 8 (P 〈 0.05). BW gain, feed intake and feed conversion ratio of male KND were higher than those of female KND (P 〈 0.05) during week 0 to week 8. The carcass yield of both strains increased from 6 weeks to 8 weeks (P 〈 0.05). The breast meat ratio was the highest at week 8 whereas the leg meat ratio was the highest at 6 weeks of age in both strains (P 〈 0.01). Lightness (L*), yellowness (b*) and juiciness of meat were the highest at 6 weeks (P 〈 0.05). Moisture, ash and fat contents of meat were the highest at 7 weeks (P 〈 0.05) and protein content was the highest at 8 weeks (P 〈 0.01). These results may provide the basic data on growth performance and meat quality of large-type KND, which can be used for genetic improvements and rearing at commercial scale.
