摘　　要：为了研究采用2种不同前处理方法对测定饲料中钙、磷含量的影响,试验采用干灰化法和双氧水法对大豆粕、玉米秸秆粉、紫花苜蓿、仔猪颗粒料、羊精料补充料5种样品进行前处理,测定其钙、磷含量。结果表明:2种方法测定的结果差异不显著(P>0.05),而采用双氧水法可以节约大量的时间与成本,因此双氧水法可以代替干灰分法。To study the effects of two different pretreatment methods on the determination of calcium and phosphorus contents in feed. Five kinds of samples including soybean meal, corn stalk powder, alfalfa, piglet pellets and sheep concentrate supplement were pretreated with the dry - ashing and hydrogen peroxide methods, and then the calcium and phosphorus contents from the samples were determined. The results showed that the difference between the results obtained with the two methods was not significant （ P 〉 0.05 ）, while the use of hydrogen peroxide method could save a lot of time and cost. Thus,it can replace the dryashing method.
