Effect of Supranutritional Dosage Selenium in Neonatal Goat Kids on Productive Performance, Physicochemical Profiles in Meat, Selenium Levels in Tissues, and Histopathological Findings

Selenium (Se) is an essential element and antioxidant that catalyzes the destruction of hydrogen peroxide formed during cellular oxidative metabolism. Doses of Se as selenomethionine (SeMe) by oral route are 0.1–0.3 mgSe/kg DM, while the dose by parenteral route with sodium selenite (Na 2 SeO 3 ) is...

Description
Summary:Selenium (Se) is an essential element and antioxidant that catalyzes the destruction of hydrogen peroxide formed during cellular oxidative metabolism. Doses of Se as selenomethionine (SeMe) by oral route are 0.1–0.3 mgSe/kg DM, while the dose by parenteral route with sodium selenite (Na 2 SeO 3 ) is 0.1 mgSe/BW. The effects of supranutritional Se supplementation on normal kids have rarely been studied. The objective of the study was to evaluate both Se sources on growth performance, Se in tissues, histopathological findings, and meat characteristics. Forty-five kids of the Pastoreña breed with 25-day age were distributed (4.7 ± 1.13 kg) in three treatments: a) control group, C: consumption with goat milk (GM: containing 0.135 mgSe/g); b) NaSe: GM plus Na 2 SeO 3 injectable, 0.25 mgSe/kg BW; c) SeMe: GM plus oral dosage, 0.3 mgSe as SeMe daily. Fifteen animals per treatment were slaughtered at 7, 14, and 21 days. Feed conversion improved ( P
