Aim: The aim was to investigate the effect of bread waste feeding on feed intake, utilization and growth performance of crossbred pigs and to evaluate the economics of bread waste feeding.
Materials and Methods: The study was conducted for a period of 3 months (December, 2012-March, 2013). Large White Yorkshire crosses (LWY X Desi) were included in the study. A total of 24 weaned crossbred growing pigs were randomly assigned to four different groups, with six animals in each group. The experimental animals were fed as per their body weight following Indian Council of Agricultural Research requirements. They were fed twice a day according to schedule at 9:00 am and 3:00 pm. The water was kept available to animals round the clock. The cost of the experimental diets was calculated based on the existing price of the ingredients during the experimental period. Samples of feed were collected for analysis of proximate principles as per Association of Official Analytical Chemist. Body weight of all animals was recorded fortnightly basis in the morning before feeding with the use of platform type electronic weighing balance. Feed conversion ratio (FCR) and protein conversion ration was calculated by using a standard formula. Data were analyzed, using one-way analysis of variance (ANOVA). Means showing significant differences in the ANOVA table were compared using the Duncan multiple range test.
Results: Crude protein content (%) of the diets was 16.01±0.02, 16.13±0.02, 16.14±0.02, 16.04±0.02, 16.08±0.02 and 12.72±0.03, respectively for the G1, G2, G3 and G4, groups. Proximate compositions (%) of diets used in the experiment were not significantly different. Digestibility coefficients of all the nutrients were significantly varied among the experimental groups. Daily feed intake was significantly (p<0.05) varied among the groups. Average daily gain (kg/pig/day) were significantly (p<0.01) higher in group G2 (0.377). FCR was significantly (p<0.01) higher in the G2 group (4.35).
Conclusion: Bread waste can economically supplement up to 50% to the diet of crossbred growing pigs.
