【 摘 要 】

The study aimed to examine the growth performance and meat quality of Pekin ducks fed diets consisting of various protein source alternatives (groups: II—yellow lupin (YL) and rapeseed meal (RSM); III—YL and narrow-leaved lupin (NLL); IV—pea and YL; V—RSM, YL, NLL and pea) to (I) soybean meal (SBM) and RSM. Four hundred and twenty ducks were assigned to five groups with six replicates (14 birds per group). After 7 weeks, 10 ducks from each group were slaughtered. Breast muscles were analyzed for water-holding capacity, drip loss, color, and elasticity. Productivity parameters did not differ between groups I and II but were lower in V. The weight of carcass, neck with skin, skin with subcutaneous fat and total fat were highest in group II. The proportion of wings was higher in group V. In group II, lightness (L*) was higher, but redness (a*) was lower. In groups, I and III, L* was lower and a* was higher. Breast muscles contained more protein in groups I and II, more fat in groups I and III and more water in groups II and IV. The inclusion of vegetable protein alternatives to SBM in duck diets provided the best results in birds fed with YL and RSM (ratio of 1:0:31 in starter and 1:0.81 in grower).
