The dietary energy for broiler chicken is provided through the inclusion of cereal grains and vegetable oil in the ration. The cost of corn is increasing exponentially, whereas sugar syrup (SS) is available with reasonable cost. Sugar syrup can be used as a substitute for starch/grains and vegetable oil. No research has been reported on the effect of SS on broiler meat quality. In this study, Hubbard commercial broiler chicks were fed a control basal diet (corn-soy basal diet on an ad libitum basis) alone or with graded levels of SS. A completely randomized design with 3 replications (n = 3, treatments = 4 with 4 subsamples per treatment) were used to investigate the effect of replacing part of the corn and oil in broiler chicken rations with graded levels of SS (5, 10, and 15%) on breast and thigh meat quality (proximate analysis, cooking loss, instrumental color, and texture and sensory properties). Rations containing up to 15% SS had a slight effect on proximate composition of raw and cooked broiler breast and thigh meats. Cooking loss of thigh meat decreased significantly with increasing SS but increased significantly for breast meats. No significant differences were detected (P > 0.05) among breast or thigh meats fed rations with a different level of SS on all sensory properties, except that cooked thigh meat had a slightly harder texture. Overall, results suggest that feeding broilers with SS rations (up to 15%) produced high-quality breast and thigh meats with minimal differences.
肉鸡的日粮能量通过在饲粮中添加谷物和植物油来提供。玉米的成本呈指数级增长,而糖浆(SS)的成本则较为合理。糖浆可以替代淀粉/谷物和植物油。目前尚未有研究报道 SS 对肉鸡肉质的影响。本研究以哈伯德商业肉鸡雏鸡为研究对象,单独或在饲粮中添加不同梯度的 SS(5%、10%和 15%),来替代部分玉米和油脂,采用完全随机设计,设 3 个重复(n = 3,处理 = 4,每个处理 4 个副样),研究在肉鸡饲粮中用 SS 替代部分玉米和油脂对胸肉和腿肉品质(常规养分分析、蒸煮损失、仪器颜色、质地和感官特性)的影响。饲粮中 SS 含量高达 15%时,对生、熟鸡肉的常规养分组成有轻微影响。随着 SS 添加量的增加,腿肉的蒸煮损失显著降低,但胸肉的蒸煮损失显著增加。不同 SS 水平饲粮对胸肉和腿肉的所有感官特性均无显著差异(P > 0.05),但煮熟的腿肉质地稍硬。总体而言,结果表明,饲粮中添加 SS(高达 15%)可生产出高品质的胸肉和腿肉,差异极小。
