This study was planned to evaluate the effect of distillery yeast sludge (DYS) as a protein source on growth performance, nutrient digestibility and slaughtering parameters in Japanese quail birds. For this purpose, six hundred day-old quails were randomly distributed into six dietary treatments. These dietary treatments were; G (Control Group) fed a basal diet (CP 24%, ME 2900 kcal/kg) without DYS, while other dietary treatments were G, G, G, G and G fed basal diet containing DYS @ 1.5, 3.0, 4.5, 6.0 and 7.5%, respectively. It was observed that feed intake and weight gain tended to increase (P < 0.05) up to 3% DYS. Better (P < 0.05) feed conversion ratio (FCR) was observed in birds fed diet containing DYS at the level of 1.5 and 3%. Dry matter and crude protein digestibility decreased with increasing levels of DYS (P < 0.05). Cost of production per 100 g of weight gain was also less in birds fed diet containing 3% DYS. Study revealed that inclusion of distillery yeast sludge in the diet of Japanese quails up to 3% improves the growth performance and economics efficacy.
本研究旨在评估酒糟(DYS)作为一种蛋白质来源对肉仔鸡生长性能、养分消化率和屠宰参数的影响。为此,将 600 只 1 日龄鹌鹑随机分为 6 个日粮处理组。这些日粮处理组为:G(对照组)饲喂基础日粮(CP24%,ME2900kcal/kg),不含 DYS,而其他日粮处理组 G、G、G、G 和 G 分别饲喂基础日粮,添加 1.5%、3.0%、4.5%、6.0%和 7.5%的 DYS。结果表明,饲粮中添加 3%以下的 DYS 可提高饲料采食量和日增重(P<0.05)。饲粮中添加 1.5%和 3%的 DYS 可改善饲料转化率(FCR)(P<0.05)。随着 DYS 添加水平的增加,干物质和粗蛋白消化率呈下降趋势(P<0.05)。每增重 100g 的生产成本也较低。研究表明,在肉仔鸡日粮中添加 3%以下的酒糟可提高生长性能和经济效益。
