摘要 在含硫氨基酸和赖氨酸水平较低的玉米 -菜粕型日粮中分别添加 0 .3%硫酸钠、0 .3%碳酸氢钠、0 .3%硫酸钠 +0 .3%碳酸氢钠 ,能提高伊莎褐蛋鸡产蛋率、蛋重及饲料利用率 ,使产蛋饲料成本下降 ,盈利值明显增加 ,对存活率则无影响 .其中尤以混合添加组效果最佳 ,其次分别为碳酸氢钠组和硫酸钠组 .研究还发现 ,日粮中添加碳酸氢钠 ,能明显增加蛋鸡的蛋壳厚度 ( P<0 .0 5) ,蛋壳强度也有显著提高 ( P<0 .0 5) . Adding 0.3% sodium sulphate or 0.3% sodium bicarbonate to corn rape seed meal type diet with low levels of sulphur containing amino acid and lysine for ISA brown laying hens, egg laying rate, egg weight and feed efficiency increased, profit per hen also increased obviously, whereas hen mortality was not influenced. When laying hens were fed diet supplemented with sodium bicarbonate, eggshell thickness and strength improved significantly ( P <0.05). It was found that addition of sodium sulphate and sodium bicarbonate both in diet was more beneficial to egg laying performance than any single supplement.
