The objective of this study was to measure the effect of substituting different levels of shrimp meal (SM) for soybean meal (SBM) in broiler diets. In Experiment 1, 0, 10, 20, 30, and 40% of the crude protein contributed by the SBM in broiler diets was substituted by crude protein from SM. In Experiment 2, 0, 60, 80, and 100% of the crude protein contributed by SBM in broiler diets was replaced by crude protein from SM. Body weight, cumulative feed consumption, and feed conversion (feed:gain) were determined on a weekly basis for 49 d in Experiment 1 and 42 d in Experiment 2. Mortality was reported daily. Carcass weight and percentage yield were determined on a prechilled basis. In Experiment 1, no significant differences were found for body weight, feed consumption, feed conversion, mortality, carcass weight, or yield. In the second experiment, body weight was found to be significantly higher (P < 0.01) at 21, 28, 35, and 42 d of age in treatments in which SM was introduced at a 100% substitution for SBM. Growth responses to SM were also seen at lower levels of substitution at 21, 28, and 35 d. No significant differences were observed for feed consumption, feed conversion, mortality, or carcass yield for any of the treatments. Carcass weight increased significantly by 12.1% when SM was substituted 100% for SBM. Results of the present study show that the particular SM used in this study could partially or totally replace SBM in broiler diets without negatively affecting performance or carcass quality.
本研究的目的是测定在肉鸡日粮中用不同水平的虾粉（SM）替代豆粕（SBM）的效果。在实验1中，用虾粉中的粗蛋白替代肉鸡日粮中豆粕提供的0%、10%、20%、30%和40%的粗蛋白。在实验2中，用虾粉中的粗蛋白替代肉鸡日粮中豆粕提供的0%、60%、80%和100%的粗蛋白。在实验1中，连续49天每周测定体重、累计采食量和饲料转化率（饲料：增重）；在实验2中，连续42天每周测定上述指标。每天记录死亡率。在预冷基础上测定胴体重和产率百分比。在实验1中，体重、采食量、饲料转化率、死亡率、胴体重或产率均未发现显著差异。在第二个实验中，在21日龄、28日龄、35日龄和42日龄时，用虾粉100%替代豆粕的处理组体重显著更高（P<0.01）。在21日龄、28日龄和35日龄时，较低替代水平下对虾粉的生长反应也很明显。任何处理的采食量、饲料转化率、死亡率或胴体产率均未观察到显著差异。当虾粉100%替代豆粕时，胴体重显著增加了12.1%。本研究结果表明，本研究中使用的特定虾粉可以部分或完全替代肉鸡日粮中的豆粕，而不会对生产性能或胴体品质产生负面影响。
