Study on the multiple-factors associative effects of forage

Abstract

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.
