The study investigated how sprouted-papaya seed meal (SPSM) a total of affected the growth and carcase traits of broilers. Based on a completely randomized design, 390 day-old Lohmann broiler chicks were allotted to CONT (chicks provided with control diet), SEED25 (diet containing 2.5% papaya seed meal), GERM1 (diet containing 1% SPSM), GERM25 (diet containing 2.5% SPSM) and GERM5 (diet containing 5% SPSM). Body weight and feed intake of chickens were weekly recorded from 14 to 36 days of age, while birds (six birds per treatment group; 30 birds in total) were slaughtered at day 36. Feeding SPSM up to 5% did not impair ( > 0.05) broilers' growth or feed intake. At 5%, SPSM compromised ( < 0.05) feed conversion ratio (FCR) and reduced breast meat proportion. SPSM at 2.5% in diets had no ( > 0.05) detrimental effects, while papaya seed meal at the same proportion lowered ( < 0.05) final body weight, weight gain, and cumulative feed intake. Overall, SPSM may be incorporated in broiler rations up to 2.5% with no harmful effects on growth, feed intake, FCR and carcase traits of broiler chickens.
本研究调查了发芽木瓜籽粕（SPSM）对肉鸡生长和胴体性状的总体影响。基于完全随机设计，将390只1日龄的罗曼肉鸡雏鸡分配到CONT组（雏鸡饲喂对照日粮）、SEED25组（日粮含2.5%木瓜籽粕）、GERM1组（日粮含1% SPSM）、GERM25组（日粮含2.5% SPSM）和GERM5组（日粮含5% SPSM）。从14日龄至36日龄每周记录鸡的体重和采食量，在36日龄时宰杀鸡（每个处理组6只鸡；共30只鸡）。饲喂高达5%的SPSM对肉鸡的生长或采食量没有损害（P>0.05）。在5%时，SPSM降低了（P<0.05）饲料转化率（FCR）并降低了胸肉比例。日粮中2.5%的SPSM没有（P>0.05）有害影响，而相同比例的木瓜籽粕降低了（P<0.05）最终体重、体重增加和累积采食量。总体而言，SPSM可添加到肉鸡日粮中，添加量高达2.5%时，对肉鸡的生长、采食量、FCR和胴体性状没有有害影响。
