In Vitro Application of Exogenous Fibrolytic Enzymes from Trichoderma Spp. to Improve Feed Utilization by Ruminants

Treating ruminant feeds with exogenous fibrolytic enzymes may potentially increase forage cell wall degradability and thus feed efficiency. In nature, fungi biosynthesize lignocellulolytic that can break down lignocellulosic material into its sugar components, thereby providing ready fermentable substrates. This work showed the in vitro activity of three Trichoderma strains (T. atroviride strain P1, T. afroharzianum T22, reesei T67). Total protein concentration enzymatic (e.g., glucanase, cellulase, xylanase) activities were determined fungal culture filtrates after 7 14 days growth on different fiber-based media. The mixtures produced by spp. highest added to industrial test their ability hydrolyze insoluble fibers. supplementation containing medium-fiber or low-fiber concentrates T22 presence lyophilized mushrooms durum wheat fiber reduced hemicellulose up 33% 24%, respectively. These results offer novel opportunities develop livestock improved digestibility.
