This study evaluated the growth performance and meat characteristics of grower geese whose diets included garlic scape meal (GSM), a by-product of garlic production. Scape is the leaf-less flower stem of garlic. Garlic scape (GS) extracts contained 84.7 ± 3.8 μg/g dry weight (DW), 81.4 ± 8.2 μg/g DW, 0.78 ± 0.05 mg gallic acid equivalent/g DW and 31.67 ± 2.25 μg/g DW of allicin, alliin, total phenolics and flavonoid contents, respectively. In total, 120 White Roman geese aged 5 weeks were randomly distributed among 12 pens and fed on a grower diet ad libitum during the growth period. Employing a completely random design, 5 males and 5 females were placed in each pen. Each treatment was applied to three pens (in total 30 birds) and the treatments comprised the following: 1) control (maize-soybean meal), 2) 5% of maize replaced with 5% of GSM (5% GSM), 3) 10% of maize replaced with 10% of GSM (10% GSM) and 4) 15% of maize replaced with 15% of GSM (15% GSM). Each group of 30 birds was treated for 8 weeks. The results revealed that the 15% GSM group was characterised by a lower feed conversion ratio than the control group; however, these groups did not differ significantly in their body weights (BWs). In addition, the 10% GSM group did not differ in both the feed conversion ratio and consumption. The flavour intensity score of meats in the 10% GSM group was significantly lower than those of meats in the 5% GSM and control groups. The general acceptability scores of meats in the 5% GSM and control groups were higher than those of meat in the 10% GSM group. The study concluded that 5% dietary GSM in the feed did not adversely affect the growth performance, meat characteristics or sensory evaluation of grower geese. Hence, the environment can be protected by including agricultural waste in goose diets.
本研究评估了日粮中含有蒜薹粉(GSM)(大蒜生产的一种副产品)的育成期鹅的生长性能和肉品质特性。蒜薹是大蒜无叶的花茎。蒜薹(GS)提取物中大蒜素、蒜氨酸、总酚和类黄酮含量分别为84.7±3.8μg/g干重(DW)、81.4±8.2μg/g DW、0.78±0.05mg没食子酸当量/g DW和31.67±2.25μg/g DW。总共120只5周龄的白罗曼鹅随机分配到12个围栏中,在生长期间自由采食育成期日粮。采用完全随机设计,每个围栏中放置5只雄性和5只雌性鹅。每个处理应用于三个围栏(共30只鹅),处理包括以下几种:1)对照组(玉米-豆粕),2)5%的玉米被5%的GSM替代(5% GSM),3)10%的玉米被10%的GSM替代(10% GSM),4)15%的玉米被15%的GSM替代(15% GSM)。每组30只鹅处理8周。结果显示,15% GSM组的饲料转化率低于对照组;然而,这些组的体重(BW)没有显著差异。此外,10% GSM组在饲料转化率和采食量方面均无差异。10% GSM组肉的风味强度评分显著低于5% GSM组和对照组肉的风味强度评分。5% GSM组和对照组肉的总体可接受性评分高于10% GSM组肉的总体可接受性评分。该研究得出结论,日粮中5%的GSM对育成期鹅的生长性能、肉品质特性或感官评价没有不利影响。因此,通过在鹅日粮中添加农业废弃物可以保护环境。
