Pelleting is a processing method that is employed by the feed manufacturing industry to improve farm animal performance. The improvements of pellet on performance have been attributed to 1) decreased feed wastage 2) reduced selective feeding 3) destruction of pathogenic organisms 4) improved palatability., Manufacturers have used various types of pellet binders to increase the durability of pellets. The bentonite type of binders would supply little nutritive value. Bentonite is tri-layered aluminium silicate having sodium or calcium as its exchangeable cation. Feed inclusion is about 1-2%, and this mineral must be hydrated to be functional. The sodium form is the best and hydration of the mineral results in a five-fold increase in weight. During this change, the aluminium silicate layers become separated, and water is attracted to their ionic surfaces creating a 12 to 15 fold increase in volume. The ingredients of bentonite are Sio2, 66%; Al2o3, 16.3%; H2o (Crystal), 60%; Fe2o3, 3.3%; Na2o, 2.6%; Cao, 1.8%; Mgo, 1.5%; K2o, 0.48%; Tio2, 0.12%. This experiment was conducted to study the effect of a local Sodium Bentonite (SB) source and comparison of pelleted and mash diets upon the performance of broiler chickens under the conditions of feed manufacturing plant.
