摘要
试验旨在研究发酵液、吸收剂和吸收剂+发酵液对马铃薯渣发酵饲料品质的影响。采用随机分组试验设计,将试验分为对照组、发酵液组、吸收剂组、吸收剂+发酵液组,吸收剂分别为莜麦秸秆、玉米秸秆、小麦秸秆、花生壳和麸皮,每个处理6个平行用于试验各指标的测定。结果表明:各试验组均能完成发酵过程,且为乳酸发酵类型。单独添加发酵液对改善马铃薯渣发酵品质效果不显著,添加吸收剂或同时添加吸收剂和发酵液可显著提高发酵饲料的乳酸含量,但对pH值、乙酸含量、氨态氮/总氮及有氧稳定性的影响效果不一。综合考虑感官评定、发酵品质、有氧稳定性及营养成分,以试验8组和试验6组效果较好。
This test researched the effect of fermented juice, absorbents, and absorbent ＋ fer- mented liquid on the fermented feed quality of potato starch residue. Using a randomized block design, the test was divided into a control group, the fermented juice group, the adsorbent group, and the adsorbent ＋ fermented liquid group. The adsorbent were naked oat straw, corn stalks, wheat straw, peanut shells and bran. Each test group produced six parallel to determine the indicators for the test. Each treatment can complete the fermentation process for lactic acid fermentation type. Adding fermented juice alone had no significant effect on improving fermenta- tion quality of potato residue. Adding absorbers or adding absorbent and fermentation juice can significantly improve the lactic acid content of the feed. However, it differently affected the pH value, acetic acid content, NH^-N/TN and aerobic stability. Considering the sensory evaluation, fermentation quality, aerobic stability and nutrients facts, the test group 8 （corn straw ＋ ferment- ed liquid） and test group 6（bran） were better than others.
