Hempseed meal (HSM) is the byproduct of hemp seeds and is rich in crude protein and fiber, making it an ideal candidate as a feedstuff for ruminants. The objective of the present study is to evaluate the effects of feeding different levels of HSM on the carcass traits of crossbred Boer goats. Forty castrated goat kids (approximately six months, 25.63 ± 0.33 kg) were assigned to one of four treatments (n = 10) in a completely randomized design. Goats were fed pelleted diets (50% forage and 50% concentrate) with additional supplementation of HSM: control with 0%, 10%, 20%, and 30% of the total diets. Goats were harvested and processed after a 60-day feeding trial. There were no significant differences (p > 0.05) in the mean values of dressing percentages, carcass weights, body wall thickness, and ribeye area among treatments. Marbling scores and percentages of moisture, fats, proteins, and collagen in the muscles showed no significant differences (p > 0.05) among the treatments. Results suggest that including up to 30% of HSM in the diet of growing meat goats does not affect their carcass traits.
麻籽粕（HSM）是麻籽的副产品，富含粗蛋白和纤维，使其成为反刍动物理想的饲料原料。本研究的目的是评估饲喂不同水平的麻籽粕对杂交波尔山羊胴体性状的影响。40只去势山羊羔（约6个月龄，体重25.63±0.33千克）被完全随机分配到四种处理之一（n = 10）。给山羊饲喂颗粒饲料（50%粗饲料和50%精饲料），并额外添加麻籽粕：对照组添加量为总日粮的0%、10%、20%和30%。经过60天的饲养试验后，对山羊进行屠宰和加工。各处理组的屠宰率、胴体重、体壁厚度和眼肌面积的平均值之间无显著差异（p>0.05）。肌肉中的大理石花纹评分以及水分、脂肪、蛋白质和胶原蛋白的百分比在各处理组之间也无显著差异（p>0.05）。结果表明，在生长肉用山羊的日粮中添加高达30%的麻籽粕不会影响其胴体性状。
