Composition and in vitro digestibility of fibrous substrates placed in deep-stacked broiler litter

Effects of Mixing Broiler Litter with Wheat Straw Before Deep-Stacking and Alkaline Hydrogen Peroxide Treatment on Feed Intake, Digestibility and Performance in Mature Wethers

“…Similarly, Park et al (199513) did not enhance digestibility of low-quality roughages embedded in a broiler litter deep-stack unless urea was added t o the stack to increase ammonia exposure. However, in both of these studies (Mandebvu et al, 1995a;Park et al, 1995b), substrates contained in dacron or dacron-covered plastic bags were embedded in a deep-stack of broiler litter without addition of other substrates o r chemicals and it is possible that mixing low-quality roughage and (or) chemicals for treatment with all litter in a deep-stack could affect nutritive value differently.…”
