The purpose of this study was to evaluate the dietary use of novel silage that was created by combining three agro-industrial wastes produced in bulk, i.e., olive mill wastewater, grape pomace, and deproteinized feta cheese whey, in the diets of broiler chickens. A total of 216 one-day-old male Ross-308 chicks were randomly allocated to three treatment groups with six replications (12 chicks per pen). Three isocaloric and isonitrogenous diets were formulated to include the examined silage at 0%, 5%, or 10%. Commercial breeding and management procedures were employed throughout the trial. At the end of the trial (day 35), tissue samples were collected for analysis. Feeding 10% silage resulted in increased (p ≤ 0.001) final body weight (p ≤ 0.001) and feed intake. Jejunum and cecum microflora, as well as breast and thigh meat microflora, were modified (p ≤ 0.05) by the dietary inclusion. Thigh meat oxidative stability was improved (p < 0.01) by the silage supplementation. In addition, breast and thigh meat fatty acid profiles were different, respectively, (p < 0.05) in the supplemented treatments compared to the control. The examined silage was successfully tested in broiler diets with potential benefits for their performance and meat quality.
本研究的目的是评估新型青贮饲料在肉鸡日粮中的使用情况，该青贮饲料由三种大量产生的农业工业废弃物混合制成，即橄榄榨油废水、葡萄皮渣和脱蛋白羊乳酪乳清。总共216只1日龄的雄性罗斯308雏鸡被随机分配到三个处理组，每组六个重复（每栏12只鸡）。配制了三种等热量和等氮量的日粮，分别含有0%、5%或10%的受试青贮饲料。在整个试验过程中采用了商业养殖和管理程序。在试验结束时（第35天），采集组织样本进行分析。饲喂10%青贮饲料可使最终体重（p≤0.001）和采食量增加（p≤0.001）。日粮添加青贮饲料可改变空肠和盲肠微生物群以及胸肉和大腿肉微生物群（p≤0.05）。添加青贮饲料可提高大腿肉的氧化稳定性（p<0.01）。此外，与对照组相比，添加青贮饲料处理的胸肉和大腿肉脂肪酸谱分别存在差异（p<0.05）。受试青贮饲料在肉鸡日粮中进行了成功测试，对肉鸡的生产性能和肉质具有潜在益处。
