A four-week feeding trial on the simultaneous replacement of 0 to 50% of soybean meal and 0 to 100% of soybean oil on the growth performance, carcass composition and profitability was conducted using 45 randomly chosen one-week-old growing Japanese quail. The five experimental diets were; D0= Diet containing 20% soybean meal and 4% soybean oil (control diet), D1= Diet, where 12.5% of soybean meal and 25% of soybean oil has been replaced by RSC; T2 = Diet, where 25% of soybean meal and 50% of soybean oil has been replaced by RSC; T3 = Diet, where 37.5% of soybean meal and 75% of soybean oil has been replaced by RSC; T4 = Diet, where 50% of soybean meal and 100% of soybean oil has been replaced by RSC. Results demonstrated that in raw rubber seed the proportion of kernel to hull is 64: 36. Proximate components of the boiled and sundried full fat rubber seed kernel (RS) were, moisture = 96.6%, ME = 5305 kcal / kg DM, CP = 17.6%, EE = 51.05%, CF = 8.5%, NFE = 18.25% and Ash = 4.6%. The body weights of the birds at 35 days of age in all dietary treatments were statistically similar. The feed intake of the quail among different dietary groups was varied significantly (p < 0.05) and there was a tendency of decreasing the feed intake at 25% and above inclusion level of RSC. The body weight gain and FCR were also statistically similar in all dietary groups. The feed cost and total production cost /kg BW of quail was also found to become steadily higher (p> 0.05) at higher RSC inclusion level. The muscle development was found to better at lower (%) RSC level, whereas the organs were enlarged at higher RSC inclusion. Results on the majority of the production parameters, and economics and carcass yield parameters suggested that the simultaneous replacement of maximum 50% soybean oil 25% soybean meal by processed RSC might be suggested, particularly, there will be a crisis in the availability of these two ingredients.
一项为期四周的饲养试验，旨在研究在生长性能、体组成和盈利方面，同时替代 0 至 50%的豆粕和 0 至 100%的大豆油，使用 45 只随机选择的 1 周龄生长日本鹌鹑进行。五种实验饲料分别为：D0=含 20%豆粕和 4%大豆油的基础饲料（对照饲料），D1=用 RSC 替代 12.5%豆粕和 25%大豆油的饲料，T2=用 RSC 替代 25%豆粕和 50%大豆油的饲料，T3=用 RSC 替代 37.5%豆粕和 75%大豆油的饲料，T4=用 RSC 替代 50%豆粕和 100%大豆油的饲料。结果表明，在生橡胶籽中，仁与壳的比例为 64:36。煮沸和晒干的全脂橡胶籽仁（RS）的近似成分包括：水分=96.6%、ME=5305 千卡/千克 DM、CP=17.6%、EE=51.05%、CF=8.5%、NFE=18.25%和灰分=4.6%。在所有饲料处理组中，35 日龄鸟的体重均无统计学差异。不同饲料组间鹌鹑的采食量差异显著（p<0.05），随着 RSC 含量的增加，采食量有下降的趋势。所有饲料组的体重增重和 FCR 均无统计学差异。随着 RSC 含量的增加，鹌鹑的饲料成本和总生产成本/千克 BW 也呈稳步上升（p>0.05）。肌肉发育在较低（%）RSC 水平时更好，而在较高 RSC 水平时器官增大。大多数生产参数、经济效益和体组成产率参数的结果表明，在最大程度上，50%的大豆油和 25%的豆粕可被加工后的 RSC 替代，特别是在这两种原料供应出现危机时。
