目前,植物原料的化学保藏,作为在青饲料青贮和保存时减少损失的有效方法之一而被广泛推广。在化学保藏剂中已应用着丙酸、乙酸、甲酸、焦亚硫酸钠等。在青贮多年生豆科和豆科——禾本科混播草牧青饲料时,许多研究者的文章都确定了苯甲酸的良好保藏效果。利用苯甲酸可降低干物质损失,而对畜体无害。我们进行了制作和饲喂青贮料的试验,青贮料由一年生饲料作物制备,用苯甲酸保藏,以研究青贮料对育肥幼牛的有效作用。试验在斯摩梭斯克省《Михейновский》国营农场进行。为此,七月底制作无生物碱的黄羽扇豆-燕麦青贮料,九月制作晚期播种的豌豆-燕麦青贮料,其中不加保藏剂的 At present, the chemical preservation of plant raw materials is widely promoted as one of the effective ways to reduce the loss of green forage during silage and preservation. Propionic acid, acetic acid, formic acid, sodium metabisulfite and the like have been used in chemical preservatives. When silage perennial legumes and legumes-grass mix grass and pasture fodder, many investigators have identified the good preservative effect of benzoic acid. Use of benzoic acid can reduce the loss of dry matter, but harmless to the carcass. We conducted trials to make and feed silage, which was prepared from annual forage crops and preserved with benzoic acid to study the effectiveness of silage on fattening young cattle. The test was carried out at the state farm “Михейновский” in the province of Smolensk. For this purpose, an alkaloid-free yellow lupine-oat silage was produced by the end of July and a late-sown pea-oat silage was produced in September with no preservative
