摘要:

为优化发酵酶解颗粒饲料的生产工艺,本研究采用“先制粒-后发酵”的厌氧发酵模式,通过设置发酵温度(31、33、35、37 ℃)、水分含量(27%、29%、31%、33%)及发酵时间(72、120、168 h)的梯度试验,共构建16个处理组,系统探究不同参数对饲料品质的影响。结果表明,当发酵温度为35 ℃、水分含量为29%、发酵时间为120 h时,饲料中酸溶蛋白占粗蛋白的比例为27.80%,活菌数达5.75×109 CFU·g-1,且无结块和霉变现象,综合发酵效果最佳。该研究结果能为发酵酶解颗粒饲料的工业化生产提供关键工艺参数,对开发具有高营养价值和益生功能的新型畜禽饲料具有指导意义。

Abstract:

To optimize the production process of fermented enzymatic pellet feed,this study adopted an anaerobic granulation-first and post-fermentation approach,a gradient experiment was conducted with fermentation temperature(31,33,35,37 ℃),moisture content(27%,29%,31%,33%),and fermentation time(72,120,168 h),resulting in 16 treatment groups to systematically investigate the effects of these parameters on feed quality. The results demonstrated that under the optimal conditions of 35 ℃ fermentation temperature,29% moisture content,and 120 h fermentation time,the acid-soluble protein-to-crude-protein ratio reached 27.80%,and the viable bacterial count was 5.75×109 CFU·g-1,with no caking or mold formation observed. These parameters collectively achieved the best fermentation outcomes. The findings provide critical industrial process parameters for fermented enzymatic pellet feed production and offer guidance for developing novel livestock feeds with enhanced nutritional value and pro-biotic functionality.

Key words: fermented enzymatic pellet feed, granulation-first and post-fermentation, fermentation parameter, viable bacterial count
