Eighteen crossbred (HS x Ghungroo) grower pigs (about 2 months age, weighing from 5.95±0.33 to 6.03±0.53 kg) were divided into three groups of six each in a randomized block design. The pigs were fed on three different experimental diets by replacing maize with bakery waste at 0, 25 and 50% in T1, T2 and T3 groups, respectively. The pigs were fed on the experimental grower rations twice daily. The average dry matter intake (g/d) was ranged from 635.0 in T1 to 690.5 in T3, respectively and same was increased (P<0.01) with increase level of bakery waste in the diets. The digestibility of DM, OM and NFE were similar (P>0.05) across the treatments, while digestibility of CP and EE were higher with both the bakery waste containing diets T2 and T3 when compared to T1. The digestibility of crude fiber decreased significantly (P<0.05) with incorporation of bakery waste in the diet. The average DM intake was 635.0±3.08, 661.6±4.07 and 690.5±3.07 g/d, respectively in T1T2 and T3 groups which was improved (P<0.01) significantly with increasing level of bakery waste in the diets. The ADG was 227.6±15.5, 230.6±5.33 and 218.4±11.69 g/d, respectively in T1, T2 and T3 groups showing similar values among the groups. Similarly, FCR was also found similar across all the treatments. The cost of production per kg LW (Rs.) ranged from 46.97±2.92 in T3 to 53.22±3.11 in T1 group which was similar across all the treatments. It was reduced (P>0.05) by Rs. 3.71 and Rs.6.25 in T2 and T3 groups, respectively in comparison to T1 group. It is concluded that maize can be replaced up to 50% with bakery waste for formulation of economic ration without affecting the growth, FCR and feed cost per kg gain in crossbred pigs.
