Dietary Date Palm Leaves Ensiled with Fibrolytic Enzymes Decreased Methane Production, and Improved Feed Degradability and Fermentation Kinetics in A Ruminal In Vitro System

Abstract Purpose The present experiment aimed to evaluate date palm leaves (DPL) treated without or with fibrolytic enzymes as a feed for ruminants. Methods employed an in vitro wireless gas production system the dietary inclusion of DPL sun-dried, ensiled 45 days. different forms replaced berseem hay (300 g/kg diet) at 0, 25, 50, 75 and 100% diet. Results Dried linearly decreased asymptotic total (GP), rate methane (CH 4 ) carbon dioxide (CO 2 production, acid detergent fiber degradability, increased lag GP (P < 0.05). also 0.05) GP, CH , CO productions, but dry matter degradability volatile fatty (VFA) concentrations were unaffected. Date production. Ensiling ruminal ammonia-N VFA. Conclusion It is concluded that can replace up diet reduce CH4 from recommended sustainable strategy environmental pollution utilization DPL. Graphical
