项目摘要

As the causes of regional differences in silage quality, temperature, kinds and population of lactic acid bacteria, kinds of forages, and sugar content of the forages were taken in the consideration in the present study.Clostridial fermentation was most enhanced around 30ﾟC and deteriorated the silage quality, but it was depressed by the addition of lactic acid bacteria inoculant. The inoculant was not usually active in improving silage quality even when enough sugars were present. While the addition of fermented green juice (FGJ,sometimes descrived as previously fermented juice), a novel additive developed by OHSHIMA in the present study, usually improved silage quality. The FGJ was prepared by macerating fresh forage with water using home blender, filtered through cheese cloth, dilute the filtrate to 20 l with 1% sugar solution, kept for 1 to 2 days under anaerobic condition., and add to silage material at 1-2ml/kg. Most of temperate grasses contained enough sugars for lactic acid fe … More rmentation and were improved their silage quality by the addition of FGJ.There was regional difference in sugar content in alfalfa and sugar additive was nessesary in Hokkaido to improve the silage quality by FGJ,but it was not necessary in Nagoya and Okayama.The addition of cellulolytic enzyme (Cellulase) was effective in enhancing the silage fermentation when sugars is deficient in the material forages. Tropical grasses were deficient in sugars rather than lactic acid bacteria for silage fermentation and usually improved their silage quality by the addition of cellulase. The addition of lactic acid bacteria or FGJ had a little or no effects on the silage quality of tropical grasses.TMR silages were prepared using Tofu cake as the basic component. If the moisture content of the silage was controlled to about 50% by adding bran or hay, silages of good fermentation quality could be obtained without sugar and lactic acid bacteria additives.The additive treatments do not improve the palatability and nutritive value of silages for cattle.

由于青贮料品质、温度、乳酸菌种类和数量的地区差异，本研究综合考虑了牧草种类和牧草含糖量，在30ﾟ℃左右芽孢杆菌发酵效果最好，降低了青贮料品质，但添加乳酸菌接种剂对青贮料品质有抑制作用。即使在糖含量足够高的情况下，接种剂通常也不能有效改善青贮料的品质。而添加发酵绿汁(FGJ，有时被称为以前的发酵汁)，这是大岛在本研究中开发的一种新型添加剂，通常可以改善青贮料的质量。FGJ是用家用搅拌器用水浸泡新鲜牧草，用芝士布过滤，滤液用1%的糖液稀释到20 L，厌氧条件下放置1~2天，添加到青贮料中1~2ml/kg。大多数温带牧草含有足够的糖来产生乳酸铁…。紫花苜蓿含糖量存在地区差异，在北海道添加FGJ可改善青贮品质，而在名古屋和冈山则不是必需的。添加纤维素酶(纤维素酶)可有效促进原料饲料糖缺乏时的青贮料发酵。热带牧草青贮发酵缺乏糖而不是乳酸菌，通常通过添加纤维素酶来改善青贮品质。以豆腐饼为基本原料，添加乳酸菌或FGJ对热带牧草的青贮料品质影响不大或不影响。通过添加麸皮或干草将青贮料的水分控制在50%左右，不添加糖和乳酸菌，可获得发酵品质较好的青贮料，但添加处理并不能改善青贮料的适口性和营养价值。较少
