Effects of Pleurotus sapidus (Schulzer) Sacc. treatment on nutrient composition and ruminal fermentability of barley straw, barley rootless, and a mixture of the two

Barley (Hordeum vulgare L.), and its derivatives, ranks fourth in cereal production worldwide, and the Pleurotus species are among the most efficient types of lignocellulolytic white-rot fungi. The objective of this research study was to evaluate the degradation of barley straw and barley rootless w...

The objective of this research study was to evaluate the degradation of barley straw and barley rootless with an inoculum of Pleurotus to improve their nutritional availability as a food source for ruminants. Two experiments were conducted; the first was to determine the effects of inoculation of Pleurotus sapidus (Schulzer) Sacc.
