本试验旨在研究真菌乳酸菌发酵液（FJLB）对含农副产品的全混合日粮（TMR）青贮饲料品质、消化率、瘤胃发酵和绵羊氮平衡的影响。TMR由稻草、玉米秸秆青贮、啤酒糟、豆腐废料、蒸汽压片玉米和矿物质混合物制备。处理由添加到TMR的青贮添加剂组成：CON（无青贮添加剂）、FJLB、COM（商业添加剂）和MIX（FJLB + COM）。将4只插管母羊分配至4 × 4拉丁方设计。MIX处理产生的pH值低于CON和FJLB处理（P< 0.01），乳酸浓度高于其他处理（P< 0.01）。纤维含量COM处理显著低于其他处理（P< 0.05）。FJLB处理在所有观察到的参数中具有与CON和COM处理相似的发酵质量和化学组成。尽管MIX和COM处理的青贮饲料品质指数（Fleig点）高于CON处理，但所有青贮饲料都具有良好的品质。没有青贮添加剂影响采食量，消化率，瘤胃发酵，或氮平衡。综上所述，添加或不添加FJLB的农副产品与湿型食品副产品混合制备的TMR青贮料均能良好地保存发酵，该产品可用作反刍动物饲料。
The goal of this study was to determine the effects of the fermented juice of epiphytic lactic acid bacteria (FJLB) on the quality of total mixed ration (TMR) silage containing agricultural by-products, its digestibility, rumen fermentation, and nitrogen balance in ewes. TMR was prepared from rice straw, corn stover silage, brewer grain, tofu waste, steam-flaked corn, and a mineral mixture. The treatments consisted of silage additives added to TMR: CON (no silage additive), FJLB, COM (commercial additive), and MIX (FJLB + COM). Four cannulated ewes were assigned to the 4 × 4 Latin square design. The MIX treatment produced a lower (P< 0.01) pH than did the CON and FJLB treatments and a higher (P< 0.01) lactic acid concentration than did the other treatments. The fiber content in the COM treatment was lower (P< 0.05) than that in the other treatments. The FJLB treatment had similar fermentation quality and chemical composition to those of the CON and COM treatments in all parameters observed. Although the silage quality index (Fleig point) was higher in the MIX and COM treatments than in the CON treatment, all silages had good quality. No silage additives affected intake, digestibility, rumen fermentation, or nitrogen balance. In conclusion, the TMR silage prepared from agricultural by-products mixed with wet-type food by-products with or without FJLB added resulted in well-preserved fermentation, and this product might be used as a ruminant feed.
