Study On The Associative Effects Of Mix Grass Pellet Of Forage Grass And Feed

The paper took mixed grass pellet of alfalfa and corn stalk or alfalfa and caragana as objects of study,studied the nutrition value of mixed grass pellet of alfalfa and corn stalk or caragana by the experiments of palatability and digestion in vitro.The results showed:①Mixed grass pellet of alfalfa and corn stalk or alfalfa and caragana could not improve the nutrient content of corn stalk and caragana significantly;②Mixed grass pellet of alfalfa and corn stalk or alfalfa and caragana could improve the palatability of corn stalk and caragana significantly;③Different mixed grass pellet had much effect to pH value (P＜0.05),and had same trend,the pH value in different time spot in 24 hours all kept 6.36-6.57,which was suitable to microbial fermentation;④Through comparing the acetic acid,propyle acid,butyric acid,acetic acid/propyle acid and TVFA,which indicated that concentration changed significantly,and becames flat,was beneficial to ruminant nutrient uptake;⑤Through the experiment of 24 hours in vitro gas production,the results showed that the mixed grass pellet of alfalfa and corn stalk or alfalfa and caragana could improve gas production and degradation rate of DM and NDF in the rumen,and had associated effects greatly.Fast degeneration part a had improve significantly(P＜0.05),slow degeneration part b had cut down significantly(P＜0.05),and degeneration part all improved significantly(P＜0.05).
