Abstract

The composition of urea treated rice milling waste and its application as animal feed was studied. The proximate analysis of the urea treated rice milling waste showed that it contained 94.90% dry matter, 10.38% crude protein, 5.89% crude fibre, 0.16% ether extract, 7.47% ash, and 54.81% nitrogen-free extracts. The untreated rice milling waste contained 94.34% dry matter, 9.11% crude protein, 6.37% crude fibre, 0.18% ether extract, 8.11% ash, and 54.69% nitrogen-free extracts. Four experimental diets were prepared containing two different levels (30 and 35%) each of untreated and urea treated rice milling waste mixed with commercial pelletized chick mash to assess their effects on weaner rabbits. Data on the feed intake, growth rate, and feed conversion ratio (FCR) of weaner rabbits fed diets containing two different levels each of untreated and urea treated rice milling waste were compared using two-way analysis of variance (ANOVA). There were no significant effects (P > 0.05) of dietary treatment and level of inclusion for average feed intake, average body weight gain, and the FCR. The study indicated that rabbits can be successfully raised on a commercial chick mash mixed with 35% rice milling waste treated or untreated without any adverse effect on growth.

尿素处理碾米废料及其饲料应用研究

研究了尿素处理碾米废料的组成及其在动物饲料中的应用。对尿素处理后的碾米废渣进行近似分析，其干物质含量为94.90%，粗蛋白质含量为10.38%，粗纤维含量为5.89%，粗醚提取物含量为0.16%，灰分含量为7.47%，无氮提取物含量为54.81%。粗蛋白质含量为9.11%，粗纤维含量为6.37%，粗脂肪含量为0.18%，灰分含量为8.11%，无氮浸出物含量为54.69%。配制4种不同水平(30%和35%)未经处理和尿素处理的碾米废料与商业颗粒化鸡泥混合的试验饲粮，以评估其对断奶兔的影响。采用双因素方差分析(ANOVA)对饲粮中分别添加未处理和尿素处理过的碾米废料的断奶兔采食量、生长率和饲料系数(FCR)进行比较。饲粮处理和包埋水平对平均采食量、平均增重和料重比无显著影响(P > 0.05)。本研究表明，在商业鸡泥中添加35%经处理或未经处理的碾米废料，可成功饲养家兔，且对家兔生长无不良影响。
