摘 要:选用 1日龄健康商品代罗曼蛋公雏 6 0 0只 ,随机分为 3组 ,每组 4个重复 ,进行 70d饲养试验 ,饲喂复合维生素设 3种不同添加水平 ,添加复合维生素 10 0g·t-1(Ⅰ ) ,2 0 0g·t-1(Ⅱ ) ,30 0g·t-1(Ⅲ ) .结果表明 ,提高育肥蛋公雏饲粮中复合维生素的含量能显著提高育肥蛋白雏的健康水平、日增重、饲料转化率及经济效益 .在复合维生素添加量从 2 0 0g进一步增加至30 0g时 ,并不能进一步提高育肥蛋白雏的日增重、饲料转化率和经济效益 ,反而呈下降趋势 .综合日增重、饲料转化率和经济效益 ,育肥蛋白雏饲粮中此复合维生素添加量以 2 0healthy commercial Roman breed egg type cockerels of 1 day old were randomly divided into 3 groups,in each of which there were 4 replications and the feeding test lasted 70 days with different doses of compound vitamins addition in each groupp diet,namely,compound vitamins 100 g·t -1 diet for group Ⅰ,200 g·t -1 diet for group Ⅱ and 300 g·t -1 diet for group Ⅲ.The results showed that the increase of the content of the compound vitamins in the diet significantly improved the healthy level,daily gain,feed conversion rate and the economic benefit of the fattening egg type cockerels.The increase of the dose of the compound vitamins from 200 g·t -1 diet to 300 g·t -1 diet did not further improve daily gain,feed conversion rate and economic benefit of the fattening egg type cockerels but showed a tendency of decline.In conclusion,from the comprehensive results of the daily gain,feed conversion rate and economic benefit,the test suggested that the optimal dose of the compound vitamins used in the diet for fattening egg type cockerels should be 200 g per t diet.
