Improving the Nutritive Values of Wheat Straw and Artichoke Petals and Their Combinations by Fungal Treatments

Abstract

Pleurotus ostreatus and Phanerochaete chrysosporium successfully to upgrade nutritional value of wheat straw in combined mixture with artichoke petals at different ratios (1:1, 1:3 and 3:1), using solid state fermentation technique. Treatment with Pleurotus ostreatus succeeded to increase protein content of wheat straw from 3.30% to 10.85 when it was mixed with artichoke petals at ratio of 1:1 and fermented for 30 days,While Phanerochaete chrysosporium increased crude protein content of wheat straw to 11.10%. Pronounced degradation of hemicellulose and lignin was recorded, when wheat straw was mixed with artichoke petals at different ratios (1:1, 1:3 and 3:1). In addition, treatment of wheat straw white rot fungi improved in vitro digestibility when artichoke petals were added. The present study indicated that fungal treatment of wheat straw when mixed with artichoke petals improved the nutritive value and digestibility of poor quality roughages and produced a nutritionally valuable feed replacing good quality roughage for ruminants.Further studies are recommended to test the digestibility coefficients of the treated materials through metabolism trials.Also feed trial is needed to estimate their trend on platability; feed intake, live body gain, feed conversion and economic efficiency.

Biotechnological Improvement of Nutritional Value of Rice straw using Fungi

“…Neutral detergent bre (NDF), acid detergent bre (ADF) and acid detergent lignin (ADL) contents were measured by o cial method Ba 6a-05 using lter bag technique (AOCS 2009). Fiber-Tec Ankom system [12], [66]. Hemicellulose was calculated as the difference between NDF and ADF While, cellulose was calculated as the difference between ADF and ADL.…”

Studies on Mites Associated With Some Stored Hay in Different Regions of Egypt

“…World wide lignocellulosic residue generation every day results in pollution of the environment and in loss of valuable materials that can be bioconverted to several added-value products (Howard et al, 2003). As these residues are renewable and in an abundant supply and they represent a potential solution to feeding animals in developing countries, Baker et al, (2014).The infestation of stored products by mites and other arthropods is usually associated with three types of damage (Stejskal 2001). Firstly, storage mites directly endanger human and animal health due to allergenic contamination of food (Olsson and Hage-Hamsten 2000).…”
