the experiment there was a highly significant p lt 0 0001 effect of rumen incubation time on dry matter disappearance as expected after 4 and 24 hours of incubation approximately 50 and 75 of dry matter had disappeared from ankom bags table 1 dry matter disappearance was measured on two consecutive days in each period but there was no significant p 0 97 effect of day on this variable treatment means are summarized in tables 3 and 4 ohhl improved p 0 105 table 2 mean dry matter disappearance by 1 77 percentage units the magnitude of the response varied considerably with incubation times but this is largely a reflection of the variation inherent in such measurements the experiment shows that administration of ohhl improved p 0 105 dry matter disapearance of corn silage in the rumen of sheep 0115 table 2 ohhl and bmd effects on feed efficiency of broiler chickens 1 no 2 yes 1 no 2 yes feed conversion mortality ohhl bmd day 0 21 day 21 35 day 0 35 day 0 21 day 21 35 day 0 35 1 1 397 1 784 1 634 2 0 0 7 2 7 2 1 353 1 794 1 620 1 3 0 8 2 2 significance 0 012 ns 0 055 ns ns ns 1 1 364 1 816 1 637 1 2 0 7 1 8 2 1 386 1 762 1 617 2 2 0 8 3 0 significance 0 071 0 000 0 014 ns ns ns significance ohhl bmd 0 025 0 094 ns ns ns ns 1 1 1.
