BACKGROUND AND AIM
Black cumin meal (BCM) is the principal by-product that can be obtained from black cumin seed ( L) after the oil is removed from the fruit and represents 70-75% of the fruit weight. The aim of this experiment was to assess the influence of feeding BCM on the carcass characteristics and meat quality of growing lambs.
MATERIALS AND METHODS
Twenty-four Awassi lambs were randomly divided into two dietary treatments. The lambs were penned individually in single pens and provided access to feed and water. The dietary treatments were no BCM (control [CON]; n=12) or 150 g BCM/kg (BCM 150; n=12) of dietary dry matter.
RESULTS
Lambs fed BCM had greater (p≤0.01) fasting live BW, and hot and cold carcass weights. Leg fat and eye muscle depth were lower (p≤0.05) in CON versus BCM lambs. Meat whiteness (L*), redness (a*), and yellowness did not differ between lambs fed the two diets.
CONCLUSION
The inclusion of BCM improves lamb carcass characteristics, but does not affect lamb meat quality.
背景与目的
黑种草粕（BCM）是从黑种草籽（L）果实中榨油后得到的主要副产品，占果实重量的70 - 75%。本实验的目的是评估饲喂BCM对生长羔羊胴体特性和肉质的影响。
材料与方法
将24只阿瓦西羔羊随机分为两种日粮处理组。羔羊单独饲养在单栏中，提供饲料和水。日粮处理为不添加BCM（对照组[CON]；n = 12）或每千克日粮干物质添加150 g BCM（BCM 150；n = 12）。
结果
饲喂BCM的羔羊空腹活体重、热胴体重和冷胴体重更高（p≤0.01）。与饲喂BCM的羔羊相比，CON组羔羊腿部脂肪和眼肌深度更低（p≤0.05）。两种日粮饲喂的羔羊之间肉的白度（L*）、红度（a*）和黄度没有差异。
结论
添加BCM可改善羔羊胴体特性，但不影响羔羊肉品质。
