Nutrient availability of wheat feed screenings in broiler diet

University of British Columbia

Content and availability of nutrients in ten wheat feed screening samples were determined using day old broiler chicks. The metabolizable energy (ME) value of wheat feed screenings (WFS)in a balanced diet was significantly (P > 0.05) higher than wheat which was used as a control diet. Growth performance of all WFS samples were higher than control diet. Diets one, two, four, seven, ten and eleven had feed efficiency ratipswhich were significantly (P > 0.05) higher than the control diet. The total average availability of sixteen amino acids in these feedstuffs ranged from 66% (control) to 84% (diet three). Among limiting essential amino acids, lysine was significantly (P > 0.05) higher (83%) in availability followed by threonine (67%) and methionine (64%). The average availability of the studied chemical elements (Ca, P, Mg, Mn, Cu, Zn) ranged from 59% (Zn) to 84% (Cu). Among the chemical nutrients tested, copper (84.28%) was the highest to be followed by manganese (76.57%) and phosphorus (74.14%) and the least was zinc (59%) in availability value. The results of these studies indicated that WFS has an acceptable potential to replace wheat with reasonable margin of profit to the producer.
