Light Intensity and Cage Position affect Meat Quality by Regulating Intestinal Flora, Inflammation and Oxidation in Broilers
A total of 1,200 male yellow-feathered broilers were randomly assigned to a 2*3 factorial arrangement. Treatments included two light intensities (4 lx and 1.5 lx) and three cage positions (upper, middle, and lower). There were six treatment groups: 4 lx-upper (Ht), 4 lx-middle (Hm), 4 lx-lower (Hs), 1.5 lx-upper (Lt), 1.5 lx-middle (Lm), and 1.5 lx-lower (Ls). Each group contained 10 replicates (cages) with 20 broilers each.
