Effect of xylanase addition in feed containing either pre-characterised wheat or wheat by-products on the performance of growing pigs

摘要

Wheat and wheat by-products vary in their available energy and protein content (Batterham et RAID., 1980) leading to unpredictable growth rate and feed use efficiency. Carbohydrase enzymes, targeting the non-starch polysaccharides in these raw materials, may improve their nutrient availability. However, questions remain over the relationship between the quality of the dietary raw materials and the level of exogenous enzyme activity required in the feed to elicit a response from pigs. Hence, the response of pigs to the use of a fungal xylanase, produced by Trichoderma longibrachiatum, was studied in diets containing wheat and wheat by-products.
