不同体质量对巴美肉羊营养价值的影响

摘要

The contents of moisture, ash, crude fat and crude protein from different anatomical locations including biceps femoris (G) , triceps (L) , longissimus dorsi (B) , supraspinatus (GS) and semitendinosus (BJ) of 20~30, 30~40, 40~50, 50~60 kg body weight Bamei lamb are detected, in order to study the effect of different weight on nutritional quality of Bamei lamb. The results show that there is a negative correlation between the moisture content and body weight, body weight has no significant effect on ash (p>0.05) , and the content of crude fat increases and then decreases with increasing weight. There is a positive correlation between content of crude protein and body weight. Under the same body weight, the anatomical location has no significant effect on chemical composition (p>0.05) .%通过对体质量20~30，30~40，40~50，50~60 kg巴美肉羊的股二头肌（G）、臂三头肌（L）、背最长肌（B）、冈上肌（GS）、半腱肌（BJ）中水分、灰分、粗脂肪、粗蛋白的测定，研究不同体质量对巴美肉羊营养品质的影响。结果表明巴美肉羊水分含量与体质量成负相关，体质量对灰分含量的影响不显著（p>0.05），粗脂肪含量随着体质量的增加呈现先增加后下降的趋势，粗蛋白含量与体质量成正相关；相同体质量下，部位因素对各理化指标影响不显著（p>0.05）。
