Abstract
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.
Keywords: bread waste, crossbred pigs,
economics, feed intake, growth performance.
