摘要: 湿态酒糟发酵蛋白饲料是玉米经酵母发酵、提取酒精后的湿渣,又经益生茵发酵、密封包装的产物。试验通过在蛋鸡粉料中添加湿态酒糟发酵蛋白饲料,观察其对控制鸡舍氨气浓度及蛋鸡产蛋量的作用效果。结果表明。饲料中添加15%湿态酒糟发酵蛋白饲料,机械上料不受影响,未发现发霉变质现象;蛋鸡采食量增加;试验组比对照组产蛋量增加6.6kg,产蛋量提高5.2%,增加收益51.7元,经济效益提高约10%。鸡舍氨气浓度大幅下降,比对照组低22.8mg/L(降低了32.0%)。

Abstract: Wet lees fermenting protein feed is prepared through that the corn is treated through yeast fermentation, extraction alcohol, probiotics fermentation and sealing packaging. The power feed of hens was added with wet lees fermenting protein feed, and then the control effects on ammonia concentration of chicken house and egg yield of laying hens were studied. The results showed that if the power feed of hens was added with 15% of wet lees fermenting protein feed, the machinery feeding wasn't affect, and there was no mildew and denaturalization phenomenon, and the feed intake of hens increased. Compared with control, the egg yield of tested group was increased by 5.2% with an increase of 6.6 kg, and the economic benefit of tested group was increased by about 10% with an increase of 51.7 yuan. The ammonia concentration of chicken house decreased largely, and it was 22.8 mg/L less than control, which was decreased by 32.0%.
