全价日粮的主要指标是日粮中营养物质、能量、维生素和微量元素的平衡性。蛋白质、维生素和其它物质的缺乏对牲畜的正常生长发育产生不良影响,并能导致饲料的非生产性消耗,结果提高畜产品成本。冬季蛋白质、微量元素、维生素和其它生物活性物质的主要来源是由收割优质鲜草而获得的人工脱水饲料。人工脱水饲料加入冬季日粮时同产生与青饲料差不多的效果,并能保证节省谷物饲料和油料作物的饼粕、籽实等专用蛋白质饲料。
The main indicator of a full-price ration is the balance of nutrients, energy, vitamins and trace elements in the diet. Lack of protein, vitamins and other substances have an adverse effect on the normal growth and development of livestock and can lead to unproductive consumption of feed, with the result of raising the cost of livestock products. The main source of winter protein, trace elements, vitamins and other biologically active substances is artificially dehydrated feed obtained by harvesting good quality fresh grass. Artificial dehydrated feed added to winter diets produces almost the same results as green fodder, and guarantees the saving of specialized protein feeds such as meal and seed from cereal and oil crops.
