青贮饲料

Round bander can automatically complete the pick-up, banding and bundle lay-up of pasture, rice, wheat and rubbed cornstalk. It is widely used in collecting and banding of dry and green pasture, rice, wheat and cornstalk, convenient for transportation, storage and deep process. It can form a complete set with diolame, realizing diolame silage for long-term storage and protection of the effective nutrition contents of the silage and increase of the silage palatability.

Third, because ensiling facilities are single , it is unreasonable to choose, the ensilage is managed improperly, cause ensilage quality to be bad, the proportion of taking the total ensilage of fine ensilage is small.

第三，由于青贮设施单一，选择不合理，青贮饲料管理不善，导致青贮饲料品质差，优良青贮饲料占总青贮饲料的比例小。

Ensiling raw materials of rational utilization, improved ensilage fine quality and proper cultivated area that increased the raw materials of fine ensiling ,etc., all main influence has arisen in the production to the ensilage , elm because forest production , city of ensilage is affect by region, ensilage production status demonstrates one's own characteristic.

合理利用青贮原料、提高青贮饲料优良品质以及适当增加优良青贮原料的种植面积等都对青贮饲料的生产起主要的影响，榆林市青贮饲料的生产由于受地域的影响，青贮饲料生产现状表现出自身特点。

Firstly, the dissertation chose the species of additives and decided the concentrations of addition. Then experiments had been carried out by using corn stover ensiled with those additives under ideal ensiling condition. After each storage and fermentation period, silage was removed from silo tin and analyzed for DM, pH, DM digestibility, NDF digestibility, organic acid composition and content, DM Recovery, silage composition, ammonia-N-to-total-N ratios of silage. Those results had been used to evaluate the effects of those additives on corn stover silage.

课题首先根据查阅的大量文献资料，确定要研究的添加剂种类和添加剂量，然后在玉米秸秆原料中添加所选的添加剂，在适宜的青贮条件下进行青贮饲料的调制试验，将经过一定发酵时间的青贮饲料开封后，通过测定玉米秸秆青贮饲料的干物率、pH值、有机酸含量及组成、干物质消失率、NDF瘤胃降解率、干物质回收率、青贮化学成分、氨态氮占总氮的比例等指标，这些测定分析结果用来确定不同添加剂对玉米秸秆青贮饲料质量的影响。

Pseudoacacia and Caragana were significantly (P.05) better than A. fruticosa in pH, lactate content and ammonia-N/total-N ratio, so that their fermentation quality was better. In addition, they were high in crude protein and low in neutral detergent fiber and acid detergent fiber, showing that they were abundant in nutritive components. A. fruticosa was the inferior silage in every evaluation in the experiment. The mixed silage of R. pseudoacacia and Caragana was the best, and the mixed silage with A. fruticosa was not recommendable. There were no obvious changes in the time before and after silaging in nutritive value of these three kinds of plants, it showed that the silage technology was good.

结果表明：刺槐、柠条青贮伺料在pH值、乳酸含量、氨态氮／总氮比值方面均显著地(P.05)好于紫穗槐处理，发酵品质良好，且粗蛋白含量高，中性洗涤纤维和酸性洗涤纤维含量低，营养价值高；而紫穗槐青贮品质在各项评定中均较差；在混合青贮中刺槐和柠条青贮混合品质最佳，与紫穗槐混合的两种混合饲料品质较差；刺槐、柠条、紫穗槐在青贮前后营养品质均无明显降低，青贮饲料品质等级均为良好，青贮效果较优。

The pH value of silages was all lower than 4.0 and the ratio of ammonia nitrogen to total nitrogen was all lower than 5.0, which improved the quality that all the silages in experiment were good.

经不同切碎方式的各组青贮饲料的有机酸含量均无显著差异（P〉0.05），pH值均在4.0以下，而且氨态氮与总氮的质量比也均在5.0以下，达到了优质青贮饲料的标准，虽然各青贮饲料的粗蛋白、粗灰分和可溶性碳水化合物含量有显著差异（P〈0.05），但均为优质的青贮饲料。

Results showed that there were no evident effects of different mechanical processes on the organic acid content(P＞0.05). The pH value of silages was all lower than 4.0 and the ratio of ammonia nitrogen to total nitrogen was all lower than 5.0, which improved the quality that all the silages in experiment were good. Though the effects of three different mechanical processes on the CP, CA and WSC contents of silages were evident, the silages were all excellent.

经不同切碎方式的各组青贮饲料的有机酸含量均无显著差异(P＞0.05)，pH值均在4.0以下，而且氨态氮与总氮的质量比也均在5.0以下，达到了优质青贮饲料的标准，虽然各青贮饲料的粗蛋白、粗灰分和可溶性碳水化合物含量有显著差异(P＜0.05)，但均为优质的青贮饲料。

The effect of silaged corn straw treated with inoculants by lactic acid bacteria and cellulase on animal performance was studied. The sheep were fed with silaged corn straw for 45 days. The gain of animal increased 4.2% compared to control fed the silage without treated with additives.
