“…Previous report demonstrated that increased Se levels from 0.10 to 0.25 mg/kg markedly increased broiler weight and reduced feed efficiency ratio, where diet premixes were prepared without Se and vitamin E (Singh et al, 2006). In the presChen et al Se increased broiler oxidation resistance ent study, the broiler production performance were not significantly improved when supplemented with 0.3, 0.5, 1.0 or 2.0 mg/kg organic selenium, which was in agreement with other reports (Swain et al, 2000;Yoon et al, 2007).…”

Selenium (Se) is an essential trace element for animal and human. Supplementation of Se usually in livestock diet has been proved as effective element. This study was conducted to investigate the effect of adding different levels of selenium yeast on growth performance, slaughter performance, immune trait, oxidation resistance, meat quality and selenium content in tissue of broilers to comprehensively evaluate the effect of selenium. A total of 540 day-old Arbor Acres (AA) broilers were selected and feeded with the diets of treatments supplemented with 0.0, 0.3, 0.5, l.0 and 2.0 mg/kg organic selenium respectively. The trial period was 42 days and divided into two periods. Our results showed that effect of different levels of selenium on growth performance, slaughter performance, the immune status, drip loss and flesh had not significant difference (P>0.05). The activities of serum glutathione peroxidase (GSH-Px), total superoxide dismutase (T-SOD), the abilities to inhibit hydroxyl radical (OH•), total antioxidant capacity (T-AOC) and the content of GSH were significantly increased along with selenium level (P<0.05), whereas the content of malondialdehyde (MDA) was significantly decreased with organic selenium level (P<0.05). Our results demonstrated that organic selenium had no obvious effect on production performance of broilers, but significantly influenced the broiler oxidation resistance.

“…Vitamin E supplemented to diets at a level of 200 mg kg -1 diet increases the response of primary and secondary antibodies in broilers subjected to high temperatures (Singh et al, 2006;Niu et al, 2009). Habibian et al (2014) observed that besides the increase in antibody responses, there was a decrease in the heterophil/lymphocyte ratio, reduced HDL and increased LDL in broiler under heat stress, supplemented with vitamin E at 250 mg/kg feed, with or without the combined addition of organic selenium, showing the pronounced effect of this vitamin.…”

ABSTRACT. This review aimed to identify the importance of vitamin E dietary supplementation to broilers subjected to heat stress in relation to metabolism, growth performance and quality of animal products and its effects on immune system. Vitamin E is the concentration of tocopherol and tocotrienol, which can be found in natural or synthetic form. This vitamin is essential for the integrity of reproductive, muscular, circulatory, nervous and immune systems of the animals. In order to reduce the harmful effects of high temperatures in poultry production, vitamin E supplementation is a viable alternative for the sector. Some studies indicate its potential antioxidant effect able to modulate inflammatory responses and physiological adjustments to mitigate the undesirable effects of exposure of broilers to high temperatures. Moreover, it has been found increased viability of animals due to the greater activation of the immune system, and improved quality of animal products given to the deposition in tissues with consequent nutritional enrichment of meat products.Keywords: antioxidant, performance, immunity, meat quality, supplementation.Estresse térmico por calor e vitamina E em rações para frangos de corte como medida atenuante RESUMO. Objetivou-se, com esta revisão, identificar a importância da suplementação de vitamina E às rações de frangos de corte submetidos a estresse por calor, em relação ao metabolismo, ao desempenho produtivo e à qualidade dos produtos de origem animal, bem como seus efeitos no sistema imune das aves. A vitamina E corresponde à concentração de tocoferol e de tocotrienol, podendo ser encontrada na forma natural ou sintética. É sabido que, essa vitamina, é essencial para a integridade reprodutiva, muscular, circulatória, nervosa e imunológica dos animais. Para reduzir os efeitos prejudiciais das altas temperaturas na produção avícola, a suplementação de vitamina E apresenta-se como alternativa viável para o setor. Alguns estudos indicam seu potencial efeito antioxidante capaz de modular respostas inflamatórias e ajustes fisiológicos para atenuar os efeitos indesejáveis da exposição das aves a elevadas temperaturas. Além disso, tem sido verificado aumento da viabilidade dos animais, pela maior ativação do sistema imune, e melhora na qualidade dos produtos de origem animal, devido à sua capacidade de deposição nos tecidos, com consequente enriquecimento nutricional dos produtos cárneos.Palavras chave: antioxidante, desempenho, imunidade, qualidade da carne, suplementação.

“…In general, erythrocytes and lymphoid organs originate from the common pluripotent stem cells. When Se was supplemented in the diet, weights of the bursa and spleen increased in broiler chickens (Singh et al, 2006). The spleen of chicken is a mixed lymphatic tissue, having both the T-and B-cell rejoins, and these data suggest that these rejoins were enhanced by Se-enriched JRS.…”

:Immune response and yolk cholesterol are crucial factors for commercial chicken producers. The objectives of this study were to investigate the effect of selenium-enriched Japanese radish sprouts (Se-enriched JRS) and R. capsulatus synergistically on immune response and cholesterol in laying hens. A total of 50 laying hens (20-wk old) were assigned to 5 dietary treatment groups, and fed diets supplemented with 2.5 μg/kg, 5 μg/kg, 10 μg/kg Se-enriched JRS and 5 μg/kg Se-enriched JRS+R. capsulatus (0.02%). Egg production and yolk color were significantly improved by the supplementation of Se-enriched JRS+R. capsulatus in the layer diet (p<0.05). Compared to the control, serum cholesterol concentration and triglyceride levels were decreased by all the treatments (p<0.05). After 8-wk of the experiment, supplementation of 5 μg/kg, 10 μg/kg and Se-enriched JRS+R. capsulatus significantly reduced yolk cholesterol and triglycerides, while the greatest reduction was observed when R. capsulatus was incorporated with Se-enriched JRS. Spleen, bursa and thymus weight were significantly increased by both the 5 μg/kg and 10 μg/kg Se-enriched JRS. Compared to the control, supplementation of 5 μg/kg and 10 μg/kg Se-enriched JRS significantly increased serum IgG and yolk IgY concentration and foot web index activity by Newcastle Disease Virus (p<0.05). After 4-wk and 8-wk of supplementation, the highest number of leukocytes was observed with Se-enriched JRS+R. capsulatus (p<0.05). The highest concentration of serum and yolk Se was found in Se-enriched JRS plus R. capsulatus treatment. Combined dietary supplementation of Se-enriched JRS and R. capsulatus might be beneficial for better health, disease protection and overall production performance.
