Two 8-week broiler experiments were conducted in floor pens to study the feeding of either lasalocid (75, 100 or 125 ppm) or monensin (99 or 121 ppm) at 3 levels of methionine (0, 0.1 or 0.2% supplemental) in the presence of roxarsone (50 ppm). 9-day-old chicks of each sex were randomly placed into each pen, with 4 replicate pens assigned to each of 18 dietary treatments. Group body-weights were taken at 28 and 56 days of age for each sex and feed conversion values calculated. At 8 weeks of age, completeness of body feathering over the thigh area of all male birds was visually determined along with percent ready-to-cook yield and abdominal fat scores on selected treatment groups.
