“…The values do not prove any significant differences between the groups in the weight of breast and thigh muscle, liver and abdominal fat. The results are in agreement with Downs et al (2000) and Payne and Southern (2005). also reported that vitamin E and Se source at 0.1 ppm did not have a significant influence on eviscerated weight, dressed weight, breast fillet yield or average maryland weight at processing.…”

“…The effects of selenium sources on the performance of broiler chickens, carcass characteristics and meat quality were studied by Echevarria et al (1988), Todorovič et al (1999), Downs et al (2000), Payne and Southern (2005). In the current study of the source of Se at 0.1 ppm did not affect the performance of broilers.…”

“…Average dressing percentage was 74.2-75.1%. Downs et al (2000) reported the average dressing percentage of 71% after an addition of 0.3 mg/kg Se in the form of selenite and Se-enriched yeast while the carcass and deboned parts yield was not influenced. The content of selected basic nutrients -dry matter, proteins and intramuscular fat in breast and thigh muscle is shown in Table 4.…”

ABSTRACT:The effect of dietary supplementation of selenium in an organic form on performance, carcass traits and selenium content in tissues of broiler cockerels Ross 308 was studied. The soya-wheat-maize diet contained 50 mg vitamin E/kg. The experiment was conducted on 810 straight-run broiler cockerels randomly divided into 3 groups: group I -control, without selenium supplement; experimental group: II -0.3 mg Se/kg, Se-enriched yeast was applied as a Se source; III -0.3 mg Se/kg, Se-enriched alga Chlorella as a Se source. The broiler chickens were slaughtered at 42 days of age. In performance traits higher (P ≤ 0.05) live weight of broiler chickens was recorded in the experimental groups (II -2 430.6 g and III -2 425.2 g). There were no significant differences between the groups in feed conversion and mortality. Se-enriched alga had the best feed conversion, and selenium supplementation slightly increased mortality in both experimental groups. No significant differences between the groups were found out in carcass traits and dressing percentage. The content of selenium in breast and thigh muscle, feathers and excrements increased (P ≤ 0.05) in both experimental groups compared to the control group. Higher values in breast and thigh muscle and in feathers were measured in the group supplemented with selenium from Se-enriched yeast, also in comparison with the group supplemented with selenium from Se-enriched alga Chlorella. The broiler chickens receiving Chlorella had a higher (P ≤ 0.05) selenium content in excrements compared to the group with Se-enriched yeast. The selenium concentration in liver was higher (P ≤ 0.05) in both experimental groups compared to the control. The supplement of selenium from Se-yeast and Chlorella in the diet for broiler chickens increased the microelement concentration in muscle.

“…post weaning. Selenium has been show to have great importance for physiological functions and to improve performance because it is indispensable in defending the body against free radicals causing oxidative damage of cell membranes DOWNS et al, 2000;. Stress by changing piglets diet and environment are important factors for the increase of free radicals.…”

An experiment was conducted to study the effects of two sources and dietary levels of selenium (Se) on performance, Se concentration and glutathione peroxidase activity in plasma and liver of piglets post weaning. A total of 126 weaned pigs male and female Large White × Landrace, at average body weight of 7.2±0.67kg were allotted to seven treatments in a randomized block design, with two Se sources (organic and inorganic), inclusion levels, two levels for the inorganic source (0.30 and 0.60ppm) and four for the organic source (0.15, 0.30, 0.45 and 0.60ppm) and one control diet without Se supplementation containing 0.095ppm, and six replicates of three animals per pen. The experimental period was 35 days post-weaning. The organic source contained 0.2067% (Se-yeast), and the inorganic 45.86% (sodium selenite) analyzed. Piglets that received supplemental Se had lower feed intake compared to those not supplemented. Furthermore, feed conversion was better with dietary supplementation of Se, and the organic source was better than the inorganic source at level of 0.30ppm. Plasma concentration of Se was higher (35.53%) in animals receiving dietary supplementation of this mineral, regardless of the sources studied. There was no effect of sources on plasma and hepatic Se, with the lowest values observed for the non-supplementation and organic Se at dietary level of 0.15ppm. There was a linear reduction of plasma GSH-Px activity with increased supplementation levels of organic Se, and the hepatic GSH-Px activity increased linearly with the increased supplementation, regardless of the source studied.

“…A deterioração oxidativa acarreta perdas nos valores nutricionais e na qualidade da carne. Para aumentar a estabilidade oxidativa da carne, antioxidantes como o Se são adicionados à dieta dos animais de cultivo, o que melhora a qualidade da carne e a torna menos suscetível a danos causados pela oxidação (Downs et al, 2000). O Se é um nutriente essencial, que participa de várias funções fisiológicas como parte integrante de uma série de selenoproteínas (Lin & Shiau, 2005a;Kohrle et al, 2005).…”

Resumo -O objetivo deste trabalho foi avaliar os efeitos da suplementação da dieta de tambacus com concentrações de vitamina E sobre variáveis de desempenho e hematológicas, bem como determinar a relação da atividade da glutationa peroxidase com a inclusão de vitamina E e selênio na dieta. Foram utilizados 250 juvenis de tambacu, divididos em 25 aquários. A dieta basal constituiu-se de ração peletizada com 32% de proteína bruta e 3.300 kcal kg -1 de energia digestível, e inclusão de 0,40 mg kg -1 de Se. As dietas-teste − isoprotéicas e isoenergéticas − foram compostas da dieta basal com diferentes concentrações de vitamina E (0, 100, 200, 300, 400 mg kg -1 ), em delineamento inteiramente ao acaso, com cinco tratamentos e cinco repetições. Não foi observado efeito significativo da suplementação com vitamina E sobre o comprimento total, volume corpuscular médio, concentração de hemoglobina corpuscular média e número de eritrócitos, nem sobre a atividade da glutationa peroxidase. Peso final e conversão alimentar aparente, no entanto, sofreram efeito dos tratamentos suplementados. O teor de 400 mg kg -1 de vitamina E melhorou o comprimento padrão e ganho de peso. A suplementação da dieta com vitamina E resulta em melhor desempenho produtivo de tambacus.Termos para indexação: Colossoma macropomum, Piaractus mesopotamicus, enzimologia, hematologia, tocoferol. Productive performance of tambacus fed diets supplemented with vitamin EAbstract -The objective of this work was to evaluate the effects of tambacu vitamin E dietary supplementation on performance and hematological variables, and determine the relationship of glutathione peroxidase activity with vitamin E and selenium suplementation. Two hundred and fifty juvenile tambacus were used, divided into 25 aquaria. The basal diet was pelleted with 32% of crude protein and 3,300 kcal kg -1 of digestible energy, with 0.40 mg kg -1 Se. Test diets -isoproteic and isocaloric -were composed of the basal diet with increasing vitamin E concentrations (0, 100, 200, 300, 400 mg kg -1 ), in a completely randomized design, with five treatments and five replications. No significant effect of vitamin E supplementation was observed on total length, mean corpuscular volume, mean corpuscular hemoglobin concentration and total erythrocyte, and on the enzymatic activity of glutathione peroxidase. However, final weight and apparent feed conversion were significantly affected by supplemented treatments. Standard length and weight gain improved using diets supplemented with 400 mg kg -1 of vitamin E. Dietary vitamin E supplementation results in better tambacu performance.
