The effect of dietary inclusion of distillers dried grains with solubles (DDGS) on carcass and meat quality of longissimus muscle was studied in 100 growing rabbits from 28 to 59days old. Diets with no DDGS (C), barley (Db20), wheat (Dw20) and corn (Dc20) DDGS at 20% and corn (Dc40) DDGS at 40% were formulated. No effects on most of the carcass traits, texture and water holding capacity were found. Barley and corn DDGS led to a higher dissectible fat percentage. Meat redness was higher with Dw20 and pH was higher with Dw20 and Db20 than with Dc20. Protein and saturated fatty acids concentration declined as corn DDGS level increased. Dc40 led to the lowest saturated/unsaturated fatty acid ratio, atherogenic index and thrombogenic index. In conclusion, dietary inclusion of these DDGS at 20% did not affect most of the carcass and meat quality traits in rabbits.
本研究旨在探讨饲粮中添加不同水平的干酒糟及其可溶物(DDGS)对 28~59 日龄生长兔胴体和肌肉品质的影响。试验选用 100 只生长兔,配制无 DDGS(C)、20%大麦 DDGS(Db20)、20%小麦 DDGS(Dw20)、20%玉米 DDGS(Dc20)和 40%玉米 DDGS(Dc40)饲粮。结果表明,饲粮中添加 DDGS 对大多数胴体性状、肉质纹理和持水力没有影响。大麦和玉米 DDGS 可提高可分割脂肪的比例。与 Dc20 相比,Dw20 和 Db20 饲粮可提高兔肉的红度,降低 pH 值。随着玉米 DDGS 水平的增加,肌肉中蛋白质和饱和脂肪酸浓度降低。Dc40 饲粮可降低饱和/不饱和脂肪酸比值、动脉粥样硬化指数和血栓形成指数。综上所述,饲粮中添加 20%的这些 DDGS 对兔的大多数胴体和肉质特性没有影响。
