| Abstract | ||
| A Study was conducted at the fish laboraty, collage of agriculture- Abu Ghraib. Sixty common carp Cyprinus carpio (average weight 49.17±1.67 gm.) were distributed after two weeks adaptation period into 5 treatment in ten glass aquaria each supplied with electric heater and aerator in order to maintain temperature and oxygen levels at suitable range of fish life. Dried Non-enzymatic-treated Sheep rumen content (DNESRC) was added with 5% to the first group (T1) while dried enzymatic-treated (multienzyme complex) sheep rumen content (DESRC) with similar percentage was added to the second group (T2) simultaneously DNESRC with 10% was added to the third group (T3) and DESRC with similar percentage was added to the fourth group (T4). Control group was fed on experimental diet without dried rumen content. Experimental fish were fed on 2% of body weight and they were weight every ten days in order to calculate the increase of fish and correct amount of food supplied. The experimental was started on 28th, Oct. 2015 and ended on 6th Jan. 2016 (70 days). Non-significant differences were noticed among groups in feed and protein intake. However the control and T2 groups exhibited greater average weight gain (22.5 and 18.75g/ fish respectively) as compared with the other groups. Highest daily growth rate was for control group 0.3215g/ fish followed by T2 group 0.268 g/ fish which were non-significantly from other treatments. As well as Relative growth rate of control group 45.515% was the best followed by T2 group 39.475% and differed significantly (P<0.05) from other treatments. Too control group and T2 group exhibited greater (P<0.05) specific growth rate (0.2325% g/ day and 0.2063% g/ day respectively). As compared with the other groups. It can be concluded the possibility of adding DESRC to the common carp diet with 10% without any deleterious influence on growth rates and weight gain | ||
