Study on the growth performance of the broiler after feeding of okara meal containing with or without non-starch polysaccharides degrading enzyme

Aim: The objective was to study the growth performance of the broiler birds after feeding Okara meal containing with or without non-starch polysaccharides degrading enzyme. Materials and Methods: 220 day-old broiler chicks were individually weighed and divided randomly into five treatment groups (T , T , T , T and T ) consisting of 44 chicks each which was further subdivided into four replicates of 11 chicks. The 1 2 3 4 5 feed consumption in each replicates of five groups was recorded daily for a total period of 6 weeks experimental feeding. Results: The average total feed consumption of six weeks was 3948.10±7.60, 4088.76±8.30, 4415.33±9.44, 4381.24±9.25 and 4728.76±10.05 (g) in groups T , T , T , T and T , respectively. The differences were statistically non-significant (P>0.05) 1 2 3 4 5 among the various groups. The average total body weight gain and average daily weight gain in birds of group T were 4 significantly higher (P<0.01) than birds of other groups except T group. It showed that 25 percent replacement of ground nut 3 cake with Okara meal and addition of non-starch polysaccharides degrading enzyme (provizyme-bro) had positive effect on growth performance of birds. The increase in weight in broilers of enzyme added group T in comparison to their counterpart 4 without enzyme group (T and T ) attributed to degradation of non-starch polysaccharides in ration, thereby, enhancing the 2 3 utilization of other nutrients. Conclusion: The findings indicated that 25 percent replacement of ground nut cake with Okara meal and addition of nonstarch polysaccharides degrading enzyme had positive effect on growth performance of birds. So, Okara meal feeding had no adverse effect on growth performance of the broilers.
