Effect of Dietary Selenomethionine Supplementation on Growth Performance, Tissue Se Concentration, and Blood Glutathione Peroxidase Activity in Kid Boer Goats

Abstract

We used 240 kid Boer goats that were divided into six groups. The control group was fed a basal diet containing 0.05 mg of selenium (Se)/kg dry matter (DM). Trial groups received the basal diet supplemented with 0.1, 0.2, 0.3, 0.4, or 0.5 mg Se/kg DM (using a commercial selenomethionine product). Trial groups showed an improvement in growth performance (P < 0.05) despite no change in average daily feed intakes (ADFIs) (P > 0.05) compared to the control group A, quadratic model showed a correlation between glutathione peroxidase activity level in whole blood and dietary Se concentration (R(2) = 0.883, P < 0.04). The best linear model showed that increasing concentrations of Se in the blood (R(2) = 0.968, P < 0.001) and muscle (R(2) = 0.942, P < 0.001) corresponded to increasing Se concentrations in feed. Accumulation of Se in different tissues and organs corresponded to increasing Se concentrations in the diet as well as to the total time goats spent feeding on supplemented diet. Kidney and muscle tissues showed the highest and lowest accumulation of Se, respectively. Thus, Se in goat meat can be increased by adding between 0.1 and 0.5 mg/kg of selenomethionine to the diet of goats.

Vitamin E and Selenium Treatment Alleviates Saline Environment-Induced Oxidative Stress through Enhanced Antioxidants and Growth Performance in Suckling Kids of Beetal Goats

“…The findings of this experiment are in line with the previous report where Vit E and Se increased blood plasma concentration of Se in goats reared in selenium-deficient soil [ 14 ]. Our results are in agreement with the previous studies in which combination of Vit E and Se increased the level of plasma Se and improved the reproductive performance in goats [ 64 , 65 ].…”

Selenium in cereals: Insight into species of the element from total amount

“…SeMet has been utilized for Se supplementation in many clinical trials, and other organic Se species, such as MeSeCys, have also been demonstrated to be suitable for Se supplementation (Čadková et al., 2018). Supplementation with SeMet improved growth performance, Se concentrations in tissue, and blood glutathione peroxidase activity in kid Boer goats (Song et al., 2015). SeMet supplementation significantly reduced aortic atherosclerotic plaque formation, improved vessel function, and decreased the inflammatory response in high fat diet fed apolipoprotein E deficient (ApoE –/– ) mice, highlighting the potential of SeMet supplementation in atherosclerosis therapy (Zhang et al., 2020).…”

A Summary of New Findings on the Biological Effects of Selenium in Selected Animal Species—A Critical Review

“…Selenium is involved in growth and development, as well as taking part in the regulation processes related with production [ 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 ], and reproduction abilities of animals [ 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 , 117 , 118 , 119 , 120 , 121 , 122 , 123 , 124 , 125 ].…”
