摘要/Abstract

摘要： 依据组合效应综合指数(MFAEI)理论,以饲草的营养评价为基础,结合肉羊育肥营养需求特点,采用体外法,测定苜蓿、番茄皮渣、玉米秸与小麦秸不同组合的pH值、24 h累积产气量(GP)、有机物质降解率(IVDOM)、微生物蛋白产生量(MCP)、挥发性脂肪酸产量(VFA),并结合MFAEI筛选出4组最优饲草配方,即苜蓿/番茄渣/玉米秸=30/10/60,此配方多项组合效应值0.80;苜蓿/玉米秸=50/50,此配方多项组合效应值0.85;苜蓿/番茄渣/小麦秸=30/20/50,此配方多项组合效应值0.82;苜蓿/小麦秸=60/40,多项组合效应值0.78,以最大限度地发挥饲草间的正组合效应,控制和消除饲料间的负组合效应,从而最大限度地发挥草食家畜的生产性能,降低饲养成本。

Abstract: This thesis is basis on the theory of multiple-factors associative effects index (MFAEI), and adopts in vitro method to determine the pH, gas production (GP), in vitro digestibility organic matter (IVDOM), microbial protein (MCP), and volatile fatty acid (VFA). To select the priority of forage formula, the alfalfa, tomato pomace, corn stalks and wheat straw are employed. According to results, the priority of forage formula are as follow: Alfalfa/tomato pomace/corn stalks=30/10/60, the values of multiple-factors associative effects is 0.80; Alfalfa/corn stalks=50/50, the values of multiple-factors associative effect is 0.85; Alfalfa/tomato pomace/wheat straw=30/20/50, the values of multiple-factors associative effect is 0.82; Alfalfa/wheat straw=60/40, the values of multiple-factors associative effect is 0.78. These forage formulas could express the maximum of positive combined effect between forage, control and eliminate the negative combined effect to perform the maximum productivity of herbivorous livestock and reduce the feeding cost.
