The effects of inclusion of persimmon peel (PP) in total mixed ration (TMR) silage on its nutrient composition, tannin content, and in vitro ruminal fermentation were studied. Four types of TMR silages containing 0, 50, 100, and 150 g/kg of PP on a dry matter basis were prepared. The dietary contents of non‐fiber carbohydrate (NFC) decreased, while soluble protein fraction increased after ensiling of the TMR. In the TMR silages, the content of insoluble tannin increased (p  < .05) with increasing PP level. The fraction of soluble protein decreased linearly (p  < .01), while that of neutral detergent insoluble protein increased linearly (p  < .01) with increasing the PP level in the TMR silages. The total gas and methane yields from the in vitro rumen fermentation of the TMR silages were lower (p  < .01) than those of pre‐ensiled TMR and declined linearly (p  < .01) with increasing PP level. These results indicate that adding PP to TMR silage may resist the breakdown of dietary protein during the ensiling process, although the ruminal fermentability of TMR possibly decreased after ensiling due to the loss of NFC.

含柿皮的全混合日粮的青贮：化学成分和体外瘤胃发酵曲线的评价。

研究了在全混合日粮(TMR)青贮饲料中添加柿子皮(PP)对其营养成分、单宁含量和体外瘤胃发酵的影响。制备了四种类型的 TMR 青贮饲料，其中 PP 含量为 0、50、100 和 150 g/kg（以干物质计）。TMR青贮后非纤维碳水化合物（NFC）日粮含量下降，而可溶性蛋白质含量增加。在 TMR 青贮饲料中，不溶性单宁的含量随着 PP 水平的增加而增加 ( p  < .05)。可溶性蛋白质的分数线性下降 ( p  < .01)，而中性洗涤剂不溶性蛋白质的分数线性增加 ( p < .01) 随着 TMR 青贮饲料中 PP 水平的增加。TMR 青贮饲料体外瘤胃发酵的总气体和甲烷产量低于 ( p  < .01) 青贮前的 TMR，并且随着 PP 水平的增加呈线性下降 ( p  < .01)。这些结果表明，在 TMR 青贮饲料中添加 PP 可以抵抗青贮过程中日粮蛋白质的分解，尽管青贮后 TMR 的瘤胃发酵能力可能由于 NFC 的损失而降低。
