Description
Tossaporn Incharoen and colleagues feed laying hens gamma-oryzanol and vitamin E forms under crowded housing, in a 2026 experiment. Hens were kept at low or high density, with each supplement alone or combined. Production, egg quality, and immune gene activity were measured during late lay. High density cut feed intake and egg output.
Vitamin E raised egg weight and egg mass. Gamma-oryzanol improved feed conversion and egg mass. Their interaction further improved conversion under high density. Crowding weakened shells, while supplements improved shell hardness. Immune and stress gene responses shifted by supplement among crowded hens. Both additives look useful at the tested level.
