AB  - This study was carried-outto study the growth performance, feed utilization and economic efficiency
of Nile tilapia fingerlings fed on different levels of guar korma meal replacement in tilapia ration instead of
soybean meal. Fish of 10 g initial body weight were classified into 4 groups (25 fingerlings/group) with 3
replicates for each. Group 1 was control group and fed on commercial diet (0% guar korma diet), group 2 fed on
treated diet supplemented with 25% guar korma meal instead of soybean meal, group 3 fed on 50% guar korma
diet and group 4 fed on 100% guar korma diet. All groups fed twice daily on the rate of about 5% from the total
weight for 10 weeks. Performance were evaluated in terms of body weight, body weight gain, specific growth
rate, condition factor, total feed intake and feed conversion ratio, returns and costs due to different levels of
guar korma substitution instead of soybean. The results showed significant reduction (p<0.01) in all
performance parameters as the level of guar korma increase in the three treated groups compared with control
group. Significant difference in feed intake and Feed Conversion Ratio (FCR) was detected among treatment
groups where feed intake decrease and (FCR) increase as the level of guar korma increase. Also, there was
significant difference in economic efficiency parameters where 25% guar korma group is higher in net returns
than other 50 and 100% guar korma treated group whereas, 0% guar korma (control group) is the highest
compared with other groups. Further studies could use guar korma as a replacement with enzymes to improve
its performance and feed utilization.
