The Effect of <i>Silybum Marianum</i> Seed, <i>Thymus Vulgaris,</i> and <i>Rosmarinus Officinalis</i> Powders in Alleviating the Risks of Aflatoxin B1 in Young Broiler Chicks

Abstract This investigation was aimed to evaluate the effects of Silybum marianum seed, Thymus vulgaris , and Rosmarinus officinalis powders their combination in alleviating risks aflatoxin B1 (AFB1) young broiler chicks. One-day-old Ross 308 male chickens were allocated 6 experimental groups from d 1 21. The dietary included: Negative control (NC) received basal diet, Positive (PC) containing 2 mg AFB1/kg diet; + 10 g/kg diet seed (SMS); (TV); 5 (RO); SMS TV RO as a blend herbs (BH). There no difference between feed intake body weight gain among (P&gt;0.05). In contrast, conversion rate (FCR) NC lower than other (P&lt;0.05). Calcium levels high-density lipoprotein cholesterol (HDL) serum samples, but activity alanine aminotransferase (ALT) aspartate (AST) higher PC Increase thigh muscle malondialdehyde (MDA) fed AFB1 significantly reduced NC, SMS, BH Chickens showed highest response respiratory burst heterophil (NBT assay) lymphocyte proliferation assays (MTT conclusion, addition studied herbs, especially contaminated could have protective effect against aflatoxicosis chickens.
