Dietary supplementation of milk thistle (Silybum marianum): growth performance, oxidative stress, and immune response in natural summer stressed broilers

The aim of the study was to investigate the influence of dietary supplementation of various levels of milk thistle (MT) on growth performance, oxidative stress, and immune response of natural summer stressed broilers. A total of 120 1-day old broiler chicks were distributed into 4 treatments: MT-0 (control), MT-5 (5 g/kg of MT), MT-10 (10 g/kg of MT), and MT-15 (15 g/kg of MT), each with 3 replicates having 10 birds per replicate.
