Effect of Bread Waste Feeding on Growth Performance and Carcass Traits of Crossbred Pigs

The study was conducted at Pig farm of AICRP on Pigs, Livestock farm, Adhartal, College of Veterinary Science & A.H., Jabalpur (M.P.) for a period of three months. A total of 36 Large White Yorkshire crosses (LWY X Desi) were randomly assigned to six different groups and diets were formulated as per ICAR (1998) standard. All the diets were isoproteinous except group-6, which was formulated as per farmers practice. Composition of the diets (Table-1) are as follows; G-1(Control); concentrate mixture-1, G-2; concentrate mixture-2 (75%)+ bread waste (25%), G-3; concentrate mixture-3 (50%) + bread waste (50%), G-4; concentrate mixture-4 (25%) + bread waste (75%), G-5; wheat bran (19.5%) + bread waste (66%) + GNC (10%) + fish meal (3%) + mineral mixture (1%) + common salt (0.5%), G -6; rice bran (50%) + bread waste (50%). At the end of the experiment, the two animals from each group were slaughtered for carcass evaluation. Daily feed intake was significantly (P<0.05) varied among the groups. Highest daily feed intake (kg/pig/day) was observed in G3 group (1.647) and lowest value observed in G6 group (1.219). Average daily gain (ADG) were significantly (P<0.01) different and highest ADG (kg/pig/day) was observed in group G2 (0.377) and lowest ADG (kg/pig/day) observed in G6 group (0.171). Carcass characteristics were not significantly varied among the experimental groups. Finally, the study concluded that bread waste could be fed to the growing crossbred pigs without affecting performance.
