Effects of Some Dietary Additives on Growth Performance and Feed Efficiency of Young Common Carp Cyprinus carpio

Effects of adding three dietary additives and their mixture to control diet (38% protein) on the growth performance and feed efficiency of young common carp Cyprinus carpio with an average weight of 16.16+0.09 g were assessed. These additives were probiotic (Saccharomyces cerevisiae yeast) (T1), amino acids (lysine and methionine) (T2), a mixture of exogenous enzymes (protease, cellulase, α-amylase, amyloglucosidase, pectinase, beta-glucanase, xylanase, phytase, lipase and beta mannanase) (T3), their mixture (T4) and control (T5). Inclusion of probiotic and exogenous enzymes showed significant (P<0.05) improvement in the growth performance and feed efficiency of the fishes compared with control and other additive diets. Otherwise, the inclusion of amino acids and the additive mixture did not show any significant (P>0.05) improvement compared with the control diet. Probiotic diet (T1) recorded greatest specific growth rate SGR (0.68%/day) and best feed conversion ratio FCR (2.84), followed by exogenous enzymes diet (0.57%/day and 3.44, respectively), while the SGR and FCR values for T2, T4 and control were decreased significantly (P<0.05). Probiotic and enzymes feed additives have proved significant enhancement of fish growth and feed efficiency.

Three intestinal bacteria isolates (namely C1, C2, and C3) from common carp (Cyprinus carpio) were isolated and identified as new potential probiotics. This research aimed to study the effect of three isolates potential probiotics addition on growth performance, survival rate and feed efficiency of common carp. Completely randomized design was assigned to fourth diet treatments with five replicates. As a control, we used the feed without any supplemention of potential probiotic. The result showed that the addition of potential probiotic bacteria (C1, C2, and C3) gave significant effect on daily growth rate, survival rate and feed efficiency and could be used in aquaculture industry to reduce feeding cost.

Carp Cyprinus Carpio

Laboratory experiments were conducted to compare the growth performance and feed efficiency of two groups, old (H1) and new (H2) of common carp Cyprinus carpio L. (97.37+0.33 g). Fishes of the H1 introduced to Iraq in 1982 and then their reproduction and farming began on a large scale, while fishes of the H2 was introduced to Iraq in 2009 by Inmaa Agricultural Enterprises Organization. H2 group indicated significantly (p<0.05) better performance in several studied parameters which included specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER), protein productive value (PPV), total apparent digestibility and apparent digestibility of protein and carbohydrates. This group also recorded significant (p<0.05) lower feed satiation level and fat deposited in the body compared to the old group (H1). Results of the current experiment concluded that there is a clear higher efficiency of the group H2 in most studied growth and feed efficiency parameters, which indicates the possibility of obtaining higher productivity and better economic profits when used in farming activities.
