Dietary supplemental microalgal astaxanthin modulates molecular profiles of stress, inflammation, and lipid metabolism in broiler chickens and laying hens under high ambient temperatures.

ABSTRACT: This research was to determine effects of supplemental dietary microalgal astaxanthin (AST) on hepatic gene expression and protein production of redox enzymes, heat shock proteins (HSPs), cytokines, and lipid metabolism in broilers (BR) and laying hens (LH) under high ambient temperatures. A total of 240 (day old) Cornish male BR and 50 (19 wk old) White Leghorn Shavers LH were allotted in 5 dietary treatments with 6 and 10 cages/treatment (8 BR or 1 LH/cage), respectively. The birds were fed corn-soybean meal basal diets supplemented with microalgal (Haematococcus pluvialis) AST at 0, 10, 20, 40, and 80 mg/kg diet for 6 wk. Supplemental AST to the BR diet linearly decreased (P < 0.10, R² = 0.18-0.36) hepatic mRNA levels of several redox status-controlling genes, heat shock prot
