青贮饲料发酵

The establishment of the evaluation system of fermentation qualitg of ensiled foragt is a better way to supervise and evaluate the ensilage quality, which is a important way and a method to improve the ensilage quality and reduce waste of the resources. It has the vital significance in enhancing the fodder nutritional value and the production performance.

牧草青贮发酵品质评定体系的建立是对青贮饲料质量好坏更好的监督与评价，是提高青贮饲料质量、减少资源浪费的重要途径与方法，同时对提高家畜饲草料营养价值以及生产性能有着重要的意义。

The results showed that the crude protein digestibility of the ensilaged milk vetch by pig was 53 76%, the recovery rates of ensilaged milk vetch N by the pig feces and urine were 39 36 % and 24 71 %, respectively.

证明猪对紫云英青贮饲料中粗蛋白质的消化率为 53.76 %，猪粪和猪尿对青贮饲料中N的回收率分别为 39.36 %和 2 4 。71%，猪粪尿沼气发酵，N的回收率达 97.9%，水解N含量为发酵前的2 。6倍。

Effects of ordinary silage and mixed silage on the Robinia pseudoacacia, Caragana and Amorpha fruticosa silage were studied by observing color, odor, texture, pH, organic acid composition and content, ammonia-N / total-N ratio, crude protein, neutral detergent fiber, acid detergent fiber and comparing their nutritive value before and after silaging. Results showed that silage quality of R.

对刺槐、柠条和紫穗槐进行了单独青贮和两两混合青贮，并从青贮饲料的色泽、气味、质地等感官品质，pH值、有机酸含量及组成、氨态氮／总氮比值这些发酵品质，以及粗蛋白、中性洗涤纤维和酸性洗涤纤维这些营养价值方面进行了分析评定。

Aim at the current situation of research on silage additives in China, the effects of different additives containing hydrochloric acid, caproic acid, lactobacillus, cellulase on the nutrient preservation and silage quality of corn stover silage had been studied in two experiments.

本文针对我国青贮添加剂的研究现状，研究了发酵促进剂和发酵抑制剂二类青贮添加剂对玉米秸秆青贮饲料质量的影响。

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。

Silage Silage is the end product of fermenting a high moisture crop (40-80% water) and storing the product is called ensiling.

青储 青贮饲料是高含水量（40~80%）的作物发酵后的最终产物，这种过程称为青贮。

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 results of silage test show that in each cutting of all treatments, the silaging result of half-hay+BM+PFJ is best, the next is half-hay ferment, result of fresh grass straight fermenting is worst. In each cutting the content of CP between half-hay+BM+PFJ and the raw material grass has tiny difference (respective discrepancy from others 0.18%, 0.60% and 0.94%).

各种处理中，半干+BM+PFJ 组与原料草粗蛋白差异最小，三茬半干+BM+PFJ 处理CP 含量和原料草分别相差0.18%，0.60%，0.94%，该处理青贮料NH3-N 最低，NDF 含量与原料草差异小，pH 最低，评定得分最高，说明半干+BM+PFJ 青贮效果最好，半干草添加PFJ 和BM 后能能促进乳酸发酵，能有效地改善苜蓿青贮的发酵品质，提高青贮饲料质量。

In the current study, the two additives were applied to silages to suppress re-fermentation by inhibiting the growth of deteriorating bacteria, and to conserve the nutritional value of silages maximally.

现将这两种添加剂分别应用于青贮饲料中，使其抑制腐败菌的生长，防止二次发酵的产生，最大限度的保存青贮原料中的营养成分。

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.

将研制的青贮剂应用于玉米秸秆的青贮大池发酵，所得青贮饲料饲喂小尾寒羊40天，发现实验组比对照组增重4.2%，表明以乳酸菌和纤维素酶作为青贮剂，应用于玉米秸秆的青贮发酵，对于提高秸秆的利用率，促进动物生长有积极作用。
