摘      要：The objectives of this study were to evaluate the effect of using multiple dietary inclusion rates of alkaline aqueous lignin by-product(AALB),in replacing a commercial binder,on the preference and feeding behavior of dairy heifers,and in vitro *** the experiment I,five pelleted diets including negative control(no-binder),commercial lignosulfonate binder,and 1.6%,3.2%,and 4.8%of AALB were *** the experiment II,five pelleted diets including negative control,positive control(2%molasses),and 1%,2.4%,and 3.8%of AALB(all combined with 2%of molasses)were *** behavior and preference were determined for 60 min per animal per *** vitro digestibility was determined for each pelleted diet for 48 h over five incubation *** from Experiment I showed animals receiving 1.6%of AALB diet showed the greatest preference(dry matter(DM),intake)and a greater number of approaches with eating than other *** preference was lower when animals received control or 4.8%AALB diets relative to other *** from Experiment II revealed animals receiving 3.8%AALB combined with molasses showed the greatest DM intake preference over 60 min,and DM intake per *** that included 2.4%and 3.8%of AALB combined with molasses presented the greatest in vitro DM ***,heifers showed a greater intake when receiving pelleted diets with 1.6%***,preference,intake over 60 min,and in vitro DM digestibility,were greater in the pelleted diets that contained higher rates of AALB when combined with molasses.
