Dusan burkutu (burkutu filtration residue) and Dusan sirfe (cereal bran): two promising cereals by-products for the feeding of sheep and goats

Abstract

Fifty kilogram (50kg) bags of Dusan burkutu (Db), the filtration residue or by-product of the popular Nigerian traditional alcoholic beverage called Burkutu or \'BKT\' and Dusan sirfe (DS), a by-product of cereal grains were both collected every month and air dried from three (3) preparation and sale centers in Minna, Nigeria for one year. Chemical analysis in the laboratory by the official procedures (AOAC, 1980) for their proximate nutrient composition was carried out. Individual results on the parameters determined in both samples revealed that Db and Ds contained comparable levels of dry matter (89.50% of Db and 88.50% for Ds) and ether extracts (4.03% for Db and 5.81% for Ds) respectively. The total ash and organic matter contents for both materials were significantly (P < 0.05) different. The ash content of Db (21.86%) was comparatively higher than that of Ds (15.14%). The result also revealed that the organic matter content of Ds (84.86%) was comparitvely higher than that of Db (78.64%). The crude protein level of Db (18.28%) was significantly different (P < 0.5) and almost twice higher than the level of Ds (9.69%). The crude fiber level of Ds (26.88%), neutral fiber, (35.48%), lignin (27.69%) and hemicellulose (63.17%) were significantly (P < 0.5) higher than in Db. Both materials contained contained comparable levels of Mn, Cu and Zn respectively. While mineral elements like potassium (0.98%), iron (0.74%), phosphorus (0.70%) and magnesium (0.35%) were significantly higher in Ds, Dusan burkutu was richer in calcium (0.32%). The result from this preliminary study revealed that the nutrient composition in both materials was adequate to meet the nutritional requirement of ruminant animals.
