Effect of different sources and levels of selenium on performance, meat quality, and tissue characteristics of broilers

Abstract

Background: Several studies indicated that dietary organic selenium (Se) usually absorbed better than an inorganic source, with high retention and bioavailability. Dietary Se as an antioxidant element affects the immune system and hematological status in animals. Therefore, the aim of this study was to evaluate the effect of dietary supplementation of bacterial selenium as an organic source on hematology, immunity response, selenium retention, and gut morphology in broiler chickens. Results: The present results revealed that supplementation of inorganic Se was associated with the lowest level of RBC, HB, and PCV with signi cant difference than ADS18-Se. In the starter stage, both T2 and T5 were associated with the signi cantly highest IgG level compared to the basal diet, while all supplemented groups showed higher IgM levels compared to the control group. In the nisher phase, all Se supplemented groups showed signi cant (P 0.05) increases in IgG, IgA, and IgM levels compared to T1. Birds fed bacterial-Se showed high intestinal villus height and better Se retention more than sodium selenite. The organic selenium of ADS18 had a superior action in improving Se retention compared to ADS1 and ADS2 bacterial Se. Conclusion: Bacterial organic Se had a bene cial effect on the villus height of small intestine led to high Se absorption and retention. Thus, it caused a better effect of Se on hematological parameters and immunity response.

Efficacy of Selenium from Hydroponically Produced Selenium-Enriched Kale Sprout (Brassica oleracea var. alboglabra L.) in Broilers

“…Additionally, the results showed increasing Se concentrations in the liver, kidney, and breast muscle with increasing Se supplementation from HPSeKS (Table 5). Oliveira et al [6] also found the deposition of Se in liver and breast muscle of broilers that increased linearly (p<0.05) with increasing dietary levels of Se from Se-enriched yeast.…”

“…The previous reports revealed that the supplements of inorganic Se from sodium selenite [25] and organic Se from Seenriched yeast [6,[26][27][28][29], selenomethionine [30], Se-enriched plants [10], and Se-enriched alga [8] did not change the productive performance of broilers. Similarly, productivity of broilers in this trial was not altered by Se supplementation, although the supplemental level of Se from HPSeKS was up to 2.0 mg/kg.…”

“…Thus, there are many organic Se sources applied in poultry diets. Se from Seenriched yeast, a well-recognized commercial source of organic Se, increased higher Se deposition in tissues of broilers when compared to inorganic Se from sodium selenite [3][4][5][6]. Se from Se-enriched alga [7,8] and Se-enriched probiotics [9] was also reported to be a good source of organic Se for chickens.…”

Exploring the effect of selenium forms on final body weight, slaughtercharacteristics and tissue selenium concentration in Aseel cockerels

“…It has also been reported that increased body weight of commercial goose received organic selenium was observed (Lukaszewicz et al, 2013) and also in broilers (Kinal et al, 2012). Many researchers reported that the Se-yeast has more efficient influence in depositing selenium to the liver and breast muscle (Marcel et al, 2014;Oliveira et al, 2014).…”

The expression of heat shock protein 70 gene with organic selenium supplementation and its effetc on productivity of broilers in tropical environment

“…Selenium (Se) is an essential trace mineral known to possess antioxidant and has a profound impact on several physiological functions and productivity. Selenium, as a part of an antioxidant enzyme (Upton et al, 2009;Surai and Fisinin, 2014), detoxifies oxygen radicals and peroxides (Oliveira et al, 2014), and can reduce heat stress caused by tropical environment climate (Ibrahim et al, 2011;Yuan et al, 2012). Organic Se commonly used in the diets of broiler chickens can be derived from yeast.…”
