Effect of dietary supplementation of brown seaweed on performance of broiler chicken

A bio-assay was conducted to evaluate the effect of dietary supplementation brown seaweed (Sargassum wigetti) on performance broilers. Broilers (400) were divided into 5 treatment groups. Each had 8 replicates with 10 birds per replicate. The chicks control (Group A) fed a basal diet. Group B diet bacitracin methylene disalicylate (BMD) at 0.005%. Treatment Groups C, D, and E received 0.07, 0.1, 0.13% seaweed, respectively. All diets made isocaloric isonitrogenous. Standard management practices followed in rearing birds. Parameters, viz. growth performance, immune response, total viable count (TVC) carcass traits studied for period six weeks. exhibited higher weight gain better feed conversion ratio compared B. consumption similar E. Mortality lower (2.5%) B, (3.75%). eviscerated, ready cook, breast, thigh, drumstick yields greater whereas giblet weights recorded D cell-mediated response significantly lymphoid organs (thymus spleen). associated TVC, by C positive B) negative A). It concluded that broilers improved cell mediated immunity, traits.
