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

Abstract

An experiment was conducted to determine the efficacy of Se from hydroponically produced Se-enriched kale sprout (HPSeKS) on performance, carcass characteristics, tissue Se concentration, and physiological responses of broilers in comparison to that of Se from Se-enriched yeast and sodium selenite. Three hundred and sixty male broilers, 10 days of age, were assigned to 6 groups, 4 replicates of 15 broilers each, according to the completely randomized design. The dietary treatments were the following: T1: control diet; T2: control diet plus 0.3 mg Se/kg from sodium selenite; T3: control diet plus 0.3 mg Se/kg from Se-enriched yeast; and T4, T5, and T6: control diet plus 0.3, 1.0, and 2.0 mg Se/kg from HPSeKS, respectively. The results found that dietary Se supplementation did not (p > 0.05) alter performance and carcass characteristics of broilers. Se supplementation increased (p < 0.05) Se concentrations in the liver and kidney of broilers. Heart tissue Se concentration of broilers fed Se from sodium selenite was lower (p < 0.05) than that of broilers fed Se from HPSeKS and Se-enriched yeast. Selenium from HPSeKS increased higher (p < 0.05) GSH-Px activity when compared to Se from sodium selenite and Se-enriched yeast. The results indicated that the efficacy of Se from HPSeKS was comparable in increasing tissue Se concentration, but higher in improving GSH-Px activity in Rbc when compared to those of Se from Se-enriched yeast.

Physicochemical Contents, Antioxidant Activities, and Acute Toxicity Assessment of Selenium-Enriched Chinese Kale (Brassica oleracea var. alboglabra L.) Seedlings

“…erefore, the amount of Se in Se-KS did not exceed the toxicity doses reported; for this reason, no signs of toxicity in animals were seen in the present experiment. Indeed, together with our previous research [18][19][20], good biological activity was proven for the Se-KS with low acute toxicity when compared with selenite. We suggest 0.05-0.15 g of the air-dried Se-KS corresponded with 0.025-0.065 mg Se per day [6] or a maximum dose of <0.7 g of the air-dried Se-KS corresponded with a tolerable dose 0.3 mg Se per adult and day [7].…”

“…Moreover, Se-Met and MSeCys were the major organic forms of Se-enriched Chinese kale seedlings [18]. e bioavailability of Se from Se-enriched Chinese kale seedlings (Se-KS) is similar to that of Se-enriched yeast but higher than that of Se from sodium selenite in broilers [19] and laying hens [20]. Furthermore, the toxicity of Se from Se-KS was studied in laying hens, and it showed less toxicity than Se from sodium selenite at 5 and 10 mg•Se/kg.…”

Effect of dietary selenium from selenium-enriched kale sprout, selenomethionine, and sodium selenite on performance and selenium concentrations in the tissues of growing quails

“…Chantiratikul et al [10] similarly found no impact of dietary Se supplementation form SeKS (0.2 to 1.0 mg/kg) on feed intake, performance, and carcass characteristics of quails. Trials in broilers also reported that Se sources from SS, SeY, SeKS, 2-hydroxy-4-methylselnobutanoic acid, and SeMet at 0.1 to 2.0 mg/kg diet did not alter feed intake and growth performance parameters [2,5], and carcass traits [13]. The Se concentration in the control diet was 0.25 mg/kg (Table 2), which met the Se requirement for quail (0.15 mg Se/kg) recommended by NRC [18].…”

“…Species of Se in SeKS were mostly present as organic forms [11]. The scientific reports found that the efficacy of Se from SeKS and SeY was comparable, but greater than that of Se from SS in laying quails [12], broilers [13], and laying hens [14]. Furthermore, Se from SeKS has been confirmed to be less toxic in laying hens [15] and in rats [16].…”

Capacidad de bioconversión de selenio inorgánico por bacterias ácido lácticas desarrolladas en un medio enriquecido

“…El Se es un elemento traza esencial que se encuentra principalmente como Se inorgánico (muchas veces como selenito o selenato) y Se orgánico en forma de selenometionina, el cual, en esta forma, es mayormente asimilable (Chantiratikul, et al, 2015). El Se tiene una ingesta diaria recomendada (IDR) de 60 µg por día para hombres y de 53 µg por día para las mujeres (Rayman, 2012).…”
