Parameters evaluated included proximate composition, in vitro gas production and fiber fractions of M. maximus - L. leucocephala leaf meal with, varying levels of Morindalucida inclusion. The findings revealed that TM2 with 70% M. maximus and 30 % L. leucocephala with no M. lucida, was at par (P>0.05) with TM3 which was 100: 25: 5% inclusion of the inclusion of Morindalucida; andthey significantly enhanced the crude protein content and overall nutritional value of the M. maximus - L. leucocephalaleaf meal. Additionally, the study demonstrates that Morindalucida improves rumen fermentation efficiency, as indicated by increased in vitro gas production. This suggests that Morindalucida could be a valuable feed additive for improving ruminant nutrition at an inclusion level not higher than 5%.enThesis
