Effect of organic and inorganic selenium supplementation on growth performance, meat quality and antioxidant property of broilers

Abstract

Ninety-six thousand one-day-old AA broilers were randomly assigned to two groups, 5 replicates in each group, and 9,600 chickens for each replicate. In the control group, 0.3 part per million (ppm) inorganic selenium (Na 2 SeO 3) was added to the diets; while in the experimental group, 0.3 ppm organic selenium (Se-enriched yeast) was added to the same basal diets. The feeding experimental period was 42 days. The results show that: (1) Organic selenium could increase daily weight gain and feed intake by 8.92 (P<0.05) and 3.99% (P<0.05), and decrease survival rate and feed conversion by 0.93 (P<0.05) and 4.84% (P<0.05), indicating that the effects of organic selenium on broiler growth performance were better than that of inorganic selenium, except for survival rate. (2) Compared with the control, meat red color degree of chest and thigh muscles were increased by 13.98 (P<0.05) and 20.83% (P<0.05); the drip losses of chest and thigh muscles were decreased by 13.57 (P<0.05) and 24.92% (P<0.05), respectively. (3) Serum glutathione peroxidase (GPX) activity in experimental group were 155.83% higher than that in the control (P<0.05). These results indicate that the effects of organic selenium on enhancing body oxidation resistance were superior to that of inorganic selenium.

<i>In-ovo</i> and dietary supplementation of selenium nano-particles influence physiological responses, immunological status and performance of broiler chicks

“…The insignificant effect on kidney function expressed by serum levels of uric acid and creatinine may indicate that no stressful condition so called 'toxicity state' was introduced in treated chicks. The above results are in agreement with Yang et al (2012) who stated no significant different in urea levels in serum of chicks receiving additional selenium in the diet. On the other hand, Elsaid (2015) found a significant decrease in plasma uric acid and creatinine levels in chicks fed diet with SeNPs.…”

“…The results of serum total protein, albumin and globulin concentrations and A:G ratio showed no statistical effect of both examined routes of SeNPs administration as well as no significant interaction between these routes in the Hubbard broiler chicks ( Table 6). The obtained results are in accordance with Yang et al (2012) who observed no effect of selenium in the diet on the serum total protein and globulin levels in chicks. The same results were observed by Selim et al (2015) who indicated no significant effect on plasma total protein, globulin and albumin contents in broiler chicks fed diet supplemented with SeNPs.…”

“…Although some significant elevations in serum ALP, ALT and AST activities were found, the obtained values were in the normal rang according to the previous studies. The obtained finding is in line with the results of Yang et al (2012), who reported no significant difference in serum AST and ALP activities in chicks fed diet supplemented with selenium. Also, Selim et al (2015) indicated no significant effect on plasma ALT, AST and ALP activities in broiler chicks fed diet with SeNPs addition.…”

“…Radwan et al (2015) also observed a significant decrease in plasma total lipids, TC and an increase in HDL-C as a result of SeNPs administration. In proportionate with these results, Yang et al (2012) reported no significant difference in serum TC, TG and HDL-C levels in chicks fed diet supplemented with selenium.…”

“…Additionally, different chemical forms and amounts of Zn can affect its absorption and utilization as a nutrient and an antioxidant or produce toxic effects (Lemire et al, 2008;Lin et al, 2013). The organic form of Zn has a higher bioavailability and is less toxic and more environmentally friendly compared with inorganic salts improving larval growth performance (Gharekhani et al, 2015;Wang & Lovell, 1997;Yang et al, 2012). Algae can absorb this inorganic form of Zn and incorporate it into proteins.…”
