One thousand two hundred and eighty chicks were housed in 32 experimental floor-pens (40 birds each) and fed 8 experimental diets based on corn and soybean meal for 47 days.
The effects of methionine sources and levels were evaluated by performance data, carcass and cut yields, feather yield and abdominal fat content.
