“…Lower feed conversion ratio (FCR) was observed in fish fed the 38 mg vit.E/kg diet. Similarly, Sau et al (2004) reported that, in rohu fry fed five semi-purified diets supplemented with 0, 50, 100, 150, 200 mg vit.E/kg diet as DL-a-tocopheryl acetate, fish fed diets containing less than 100 mg supplemental vit.E/kg diet had significantly (P \ 0.05) reduced WG, FER and other nutritional indices compared to those fed diets supplemented with vit.E at 100-200 mg/kg diet. Values of PER were significantly higher in 115.70 mg/kg diet vs other groups and lowest in control group (without supplementation of vit.E), at the last, FCR was observed in fish fed the diet supplemented with 100, 150 and 200 mg/kg diets.…”

A 2 9 3 factorial experiment was designed to study the effect of sublethal toxicity of technical grade copperoxychloride, dietary vitamin E and their interactions on growth performance, some blood parameters, DNA fragmentation and histopathological lesions of Nile tilapia (Oreochromis niloticus). The 96 h LC 50 of copperoxychloride was found to be 129.21 mg/l. Four hundred and fifty fingerlings with an average initial body weight ranged from 1.92 to 2.04 ± 0.11 g were randomly distributed equally in six treatments (T1-T6) with each of triplicates. T4, T5 and T6 were exposed to sublethal concentration 0.25 LC 50 of copperoxychloride. Fish of T1, T2 and T3 fed diet supplemented with different levels of vitamin E (0, 1 and 2 g/kg diet), respectively. While fish of T4, T5 and T6 fed diet supplemented with different levels of vitamin E (0, 1 and 2 g/kg diet), respectively. At the end of the experiment (90 days) the results indicated that fish exposed to 0.25 LC 50 of copperoxychloride and fed diet with normal level of vitamin E, showed significantly lower values (P \ 0.01) of all growth and feed utilization parameters, white blood cells and immunoglobulin M, but they showed significantly increased (P \ 0.05) values of alanine aminotransferase, aspartate aminotransferase, hematocrit, hemoglobin, uric acid and creatinine. Fish fed with varied concentrations of vitamin E neutralized the toxic effect of copperoxychloride as well as vitamin E, significantly lowered the hematological and biochemical response and enhanced the growth parameters and feed utilization. The toxic effect of copperoxychloride exposure and vitamin E feeding on histopathological alterations of liver and gill of the same studied fish will be taken in concern. The results showed improvement in samples treated with vitamin E. This study suggests that vitamin E can be effectively used to decrease the toxic effect of copperoxychloride on O. niloticus and its amelioration through dietary vitamin E supplementation.

“…Vitamin D 3 (cholecalciferol) promotes and enhances the absorption and metabolism of calcium and phosphorus in our body. α-Tocopherol is the vitamin E compound with the highest biological activity, which acts as an antioxidant, protecting membrane structures, essential fatty acids, and vitamin A from oxidation (Sau et al, 2004 andPaul et al, 2005).…”

Fatty acid, amino acid and vitamin composition of indian catfish, magur (Clarias batrachus) and singhi (Heteropneustes fossilis)

The fatty acid, amino acid and fat soluble vitamin content of magur (Clarias batrachus) and singhi (Heteropneustes fossilis) were assayed from collected samples from different geographical locations. Length and weight of collected samples were (50-235g and 165-300 mm) for magur and (50-210g and 190-255mm) for singhi. The essential amino acid (EAA) and the non-essential amino acid (NEAA) content in magur and singhi did not differ significantly. The Vitamin A and D contents were significantly (P<0.05) higher in magur when compared to singhi. The Vitamin K content was significantly (P<0.05) higher in singhi compared to magur. Monounsaturated fatty acid (MUFA) content was 38.34±4.62 and 49.69±7.82 in magur and singhi respectively. Among the MUFA, oleic acid was significantly (P<0.05) higher in singhi. Palmitic acid was significantly (P<0.05) higher in magur than singhi. The PUFA content were 25.52±1.40 and 13.86±0.64 in magur and singhi respectively. The eicosapentanoic acid (EPA) and docosahexaenoic acid (DHA) content were 2.98±1.00 and 3.60±1.11; 2.25±0.86 and 1.60±1.09 respectively in magur and singhi. The ω3:ω6 ratio in magur was 0.45:1 and in singhi 0.82:1. Both the catfishes were found to be nutrient rich with amino acid, fatty acid and vitamin.

Pacu (Piaractus mesopotamicus Holmberg, 1887) is a valued Brazilian fish species for aquaculture. This is highly susceptible to disease, and feed supplementations for pacu can be a very important strategy to prevent disease incidence in fish farms. The aim of this study was to evaluate a strategic supplementation for pacu. Juvenile pacu (10.5 ± 1.2 g) were fed diets containing three levels of vitamins C and/or E (0, 250, and 500 mg vitamin kg -1 diet). Fish were fed diets without supplementation for two months prior to the experiment. After that period, experimental feeding was initiated for two months. Growth and hematological evaluations were made on the thirtieth and sixtieth days of feeding. Pacu fed diet without supplementation of vitamins C and E during 120 days did not show clear typical signs of deficiency. Fish fed diet vitamins C and E free increased feed intake, but no improvement on growth performance was detected. Vitamin E proved essential for erythrocyte protection, so that the higher the level of this vitamin in diet, the smaller the number of erythroblasts. Supplementation with 500 mg of vitamin C and 250 mg of vitamin E for 60 days increased the production of monocytes, thrombocytes and special granulocytic cells in pacu. Key words: Piaractus mesopotamicus, ascorbic acid, feed supplementation, tocopherol Desempenho e hematologia do pacu alimentado com dietas suplementadas com vitaminas C e/ou E RESUMO: O pacu (Piaractus mesomotamicus Holmberg 1887) é uma espécie altamente valiosa para a aqüicultura brasileira. Entretanto, trata-se de uma das espécies mais susceptíveis a doenças. Por isso, a suplementação alimentar para o pacu pode representar importante estratégia de prevenção da incidência das enfermidades em pisciculturas. Pacus (10,5 ± 1,2 g) foram alimentados com dietas contendo três níveis de vitamina C e/ou E (0, 250 e 500 mg vitamina kg -1 de dieta). Os peixes foram alimentados com dieta não purificada sem suplementação durante os primeiros 60 dias para reduzir as reservas teciduais das vitaminas. Após este período, os peixes foram alimentados com as dietas testadas durante 60 dias. As avaliações de crescimento e hematologia foram realizadas no 30° e 60°d ias. Pacus alimentados com dieta sem suplementação com as vitaminas C e E durante 120 dias não apresentaram sinais claros típicos de deficiência. Os peixes que receberam a dieta deficiente em vitamina C e E apresentaram maior consumo de ração, porém sem melhora no desempenho produtivo. A vitamina E mostrou-se essencial para a proteção dos eritrócitos, sendo que quanto maior o nível desta vitamina na dieta, menor o número de eritroblastos. A suplementação com 500 mg de vitamina C e 250 mg de vitamina E durante 60 dias aumentou a produção de monócitos, trombócitos e células granulocíticas especiais em pacu.
