The Effect of Gum Arabic and Technomus as a Prebiotics on the Growth Parameters of Common Carp Cyprinus carpio L.

Abstract

Abstract This study was conducted at the first agricultural research and experiment station, Agriculture college, Al-Muthanna university, for 85 days, including the localization period (for the period from 25/9/2022 to 20/12/2022), to determine the effect of adding gum Arabic and technomus as a prebiotic to the diet of common carp (Cyprinus carpio L.) on growth parameters. 162 common carp were used, with an average weight of 75±5 gm per fish, in 27 small tanks (baskets) of 0.107 cubic meters, they were randomly distributed to nine treatments with three replicates (6 fish for each replicate), were as followed: T1: (control treatment; without adding). T2: add 0% technomus with 0.5% gum Arabic to the diet. T3: add 0% technomus with 1.0% gum Arabic to the diet. T4: add 0.5% technomus with 0% gum Arabic to the diet. T5: add 0.5% technomus with 0.5% gum Arabic to the diet. T6: add 0.5% technomus with 1.0% gum Arabic to the diet. T7: add 1.0% technomus with 0% gum Arabic to the diet. T8: add 1.0% technomus with 0.5% gum Arabic to the diet. T9: add 1.0% technomus with 1.0% gum Arabic to the diet. The results showed a significant (P≤0.05) superiority of T8 compare with T1 and T2 treatments on weight gain, final weight, daily weight gain, relative growth rate, and specific growth rate. T7 was significantly superior to control treatment at the same traits.
