ABSTRACT The effects of rice bran and corn on ensiling characteristics of potato vines were investigated. Ruminal fermentation of potato vine silage was measured using a rumen simulation technique (Rusitec). Potato vines were treated (fresh weight basis) for ensiling without additives (control), with 15% rice bran and with 15% rice bran plus 3% corn, 5% corn, or 7% corn, respectively. Silage with 5% corn was chosen for a ruminal fermentation trial, based on the results of ensiling quality. Comparison of rumen fermentation between two silage (silage with 5% corn and whole corn silage) diets was conducted using a Rusitec apparatus. Adding rice bran and corn improved the potato vine silage quality (P < .05). Compared with whole corn silage, potato vine silage diet had lower (P < .05) methane production, ruminal pH, acetate, and acetate to propionate ratio and higher (P < .05) total volatile fatty acids, total nitrogen (N), ammonia-N, and microbial-N. These findings indicated that rice bran and corn improved ensiling fermentation characteristics of potato vines, and that additive-treated potato vine silage had no adverse effects on rumen fermentation and could improve the energy and N utilisation and alleviate the methane pollution of the rumen compared with whole corn silage.

确定添加米糠和玉米的马铃薯藤青贮饲料的青贮特性及体外瘤胃发酵潜力评价
摘要 研究了米糠和玉米对马铃薯葡萄藤青贮特性的影响。使用瘤胃模拟技术(Rusitec)测量马铃薯藤青贮饲料的瘤胃发酵。分别用 15% 米糠和 15% 米糠加 3% 玉米、5% 玉米或 7% 玉米对马铃薯藤进行青贮处理(鲜重基础),无添加剂(对照)。根据青贮质量的结果,选择含有 5% 玉米的青贮饲料进行瘤胃发酵试验。使用 Rusitec 设备对两种青贮饲料(含 5% 玉米的青贮饲料和全玉米青贮饲料)的瘤胃发酵进行比较。添加米糠和玉米提高了马铃薯藤青贮的品质(P < .05)。与全玉米青贮相比,马铃薯藤青贮饲料的甲烷产量、瘤胃 pH 值、醋酸盐、和乙酸与丙酸的比率以及更高 (P < .05) 的总挥发性脂肪酸、总氮 (N)、氨氮和微生物氮。这些研究结果表明,米糠和玉米改善了马铃薯藤的青贮发酵特性,添加剂处理的马铃薯藤青贮对瘤胃发酵没有不利影响,与整体相比,可以提高能量和氮的利用率,减轻瘤胃的甲烷污染。玉米青贮。
