Abstract: A biological experiment was conducted to explore the economics of Large White Yorkshire piglets fed with conventional concentrate diet incorporated with wet brewer’s spent grains (T₁), Moringa oleifera leaves (T₂) and rice gluten meal (T₃) at 10, 10 and 5% level, respectively and conventional concentrate diet kept as control (T₄). The study was carried out using 24 weaned Large White Yorkshire piglets available at Instructional Livestock Farm Complex, Veterinary College and Research Institute, Namakkal for 120 days period. The data on feed cost, total body weight gain and feed consumed per kilogram gain during the grower period are worked out and among the treatment groups, the pigs fed with 10% wet brewer’s spent grains (T1) had registered the lowest feed cost (1683.00) followed by the conventional concentrate control diet (1812.03) and 5% rice gluten meal (1890.09). The lowest (Rupees) feed cost (72.41) per kg gain in body weight recorded in 10% wet brewer’s spent grains (T1) followed by conventional concentrate control diet (72.87) and 5% rice gluten meal (73.28). The pigs fed with 10% Moringa oleifera leaves (T2) had registered the highest feed cost (85.08) per kilogram gain in body weight. The pigs fed 10% wet brewer’s spent grains (T1) had a net gain of Rs. 36.25 per pig over the control group during the grower period. Hence, it is concluded that among the treatment groups, 10% wet brewer’s spent grains was considered more suitable, economical alternative protein source to the small holding farmers which can be included at grower stage.
