Effect of Biologically Treated Wheat Straw with White-Rot Fungi on Performance, Digestibility and Oxidative Status of Rabbits

Enzymes production of whiterot fungi was assayed in myco-straw and the mean value was recorded. Wheat straw has been treated with the three most effective fungal
species with Biological Treated Wheat Straw (BTWS). After that, the myco-straw was grounded and included in diet to evaluate the growth
performance, digestibility and blood parameters of a growing V-line rabbit. Results: The best three species for enzyme productions were
P. sajor-caju, P. columbinus and P. floridanus. The optimum incubation period was 16 days. The fungal treatments showed significant
enzymes activity of laccase, Mn-peroxidase, cellulase and xylanase. Body weight, body weight gain and feed conversion ratio of growing
V-line rabbits had improved than those of the control. But, nutrients digestibility of the diet containing BTWS and Carcass traits of growing
V-line rabbits were non-significant compared with the control one. In comparison with control, the lipid profile had no differences but
the total protein was improved. Conclusion: White-rot fungal conversion of wheat straw is maybe one potential alternative providing
a more practical, environmental-friendly and nutritionally enhancing as rabbits feedstuff. Rabbits fed BTWS-diets had significantly
improved growth performance.
