Mash is given to lower costs and ascites in broilers but also reduces growth and meat yield. We describe effect mash or pellet given with or without silymarin supplement on growth, carcass traits and meat quality in broilers. Groups of 20 day old Arbor Acre chicks were given basal mash, pellet with or without 500 or 2500ppm silymarin diets. At day 42 birds were slaughtered for carcass characteristics and meat quality. Compared with mash controls, We found that birds given mash with 2500 ppm silymarin by day 42 had increased (p<0.05) live body (~14%), thigh muscle (9%) and breast muscle dry matter (6%) weights. We found large declines in breast and thigh muscle fat content (28 to 58%) in birds given mash with 2500ppm silymarin. However, we found no difference with pellet diets compared with mash diets with or without silymarin. Compared with controls none of the diets affected meat pH, odor, color, texture, hardness or standard traits.
