Palygorskite Supplementation Improves Growth Performance, Oxidative Status, and Intestinal Barrier Function in Cherry Valley Ducks.

ABSTRACT: The effects of dietary palygorskite (Pal) supplementation on growth performance, oxidative status, and intestinal barrier function in ducks were investigated. In total, 720 one-day-old Cherry Valley ducks were categorized into 4 treatments comprising 6 replicates with 30 ducks each. Ducks were fed a basal diet supplemented with 0, 5, 10, or 20 g/kg Pal for 42 days. Twenty-four ducks (1 male/replicate) were slaughtered at 14 and 42 days and samples were collected for analysis. Pal supplementation quadratically increased weight gain and linearly and quadratically increased feed intake (P<0.05) during the starter period. Pal enhanced serum glutathione peroxidase activity (GSHPx) at 14 (linear and quadratic, P<0.05) and 42 days (linear, P<0.001), and lowered serum malondialdehyde (MDA) content
