Effect of food additives, Thepax and Labazyme on growth performance and immune response of young common carp Cyprinus carpio L.

Abstract

This study was carried out for 60 day. A total number of 70 fish (Cyprinus carpio L.) with an average of 13.40±1.85 g and a length 11.07 ±1.27 cm were randomly divided into five treatments as a two tank treatment, similar to its contents of conventional ingredients (i.e., fishmeal, soybea soybean meal, corn, barley and wheat bran as well as vitamin mixture premix and carboxy methyle celloluse (CMC)). They differ in their content from food additives. They were commercially ready made in dietary T1 and T2 (Thepax 0.5, 1 gm/ kg), T3 and T4 (Labazyme 1, 2 gm/ kg) and control (0.0 gm/kg) of experimental diets. Data collected included fish weight and feed conversion ratio measured at the end of the study. The results found that the addition of food additives has significantly been affected by weight gain, specific growth rate and feed conversion ratio (P<0.05), with the best results obtained in fish food additives, pellets have been supplemented to Thepax 1 gm/ kg to enhance growth and immune responses.

The Effect of Some Food Additives on Growth Parameters of Grass Carp Ctenopharyngodon idella Fingerlings

“…C treatment, this may be explained due to the small size of fish used in the present study and the alimentary canal was not completely developed so the benefits of the microbial flora balance of intestine did not achieved by Thepax (probiotic), while vit. C may have direct plays an important role in certain aspects of protein metabolism and has a specific effect on fish growth, also few studies about using this additive in fish diets showed that supplemented diet with Thepax enhance growth and immune responses in common carp Cyprinus carpio, but the values of FCR (7.71-7.93) were much higher than the present study (Al-Mhanawi et al, 2021). Al-Jubouri & Saleh (2017) found that Thepax treatment was although significantly different from control but growth parameters of common carp values were less than other fourth treatments.…”

“…Probiotics are live microorganisms which, when added in suitable amounts, confer a health benefit of the host (FAO/WHO 2002).Yeast was used as fed for farm animals for more than a hundred years (Owens and McCracken, 2007;Bajagai et al, 2016), it contains a high amount of enzymes, amino acids, fatty acids, vitamins and unknown growth factors, but in aquaculture only a few species were used, the most common was Saccharomyces cerevisiae (Encarnação et al, 2016;Agboola et al, 2021). Yeast (Thepax) acts as a probiotic in feed poultry (Yousefi & Karkoodi, 2007;Fazli et al, 2008;Zarei et al, 2011;Boostani et al, 2013) while other researchers consider Thepax as prebiotic (Nikpiran et al, 2013;Al-Mhanawi et al, 2021), however the manufactured companies cite it as prebiotic because its consist from cell wall of yeast Saccharomyces cerevisiae, mannan and glucan (Nikpiran et al, 2013). Most works about Thepax as food additive was applied in broiler performance nutrition such as Japanese Quails (Nikpiran et al, 2013) and broiler chickens (Boostani et al 2013) which show positive effects on weight performance .…”

Effects of Some Dietary Additives on Growth and Health Status of the Young Common Carp Cyprinus carpio

“…As it worked as a catalyst for fish growth, as well as a study of Hoseinifar et al (2019) when using the bacterium Pediococcus acidilactici as a probiotic and a prebiotic and mixing them as a synbiotic mixture and adding them to the diets of carp fish led to a significant improvement in the final weight, weight gain and daily growth rate The treatment of the Synbiotic mixture was higher than the use of the probiotic and the prebiotic alone, while the effect of the use of the prebiotic thepax and the synbiotic mixture labazyme on young carp fish, and these food additives had a significant effect on weight gain and specific growth rate, The best results were when adding 1 g/kg of the prebiotic feed thepax to enhance the growth of fish (Al-Mhanawi et al, 2021), and the study of Sutriana et al (2021) showed when the prebiotic were added individually or in combination with yeast and galacto oligosaccharide, mannan oligosaccharide and βglucan on the growth performance of catfish. The treatment of 1% GOS and the treatment 1% yeast + 0.1% β-glucan.…”
