The effect of betaine and dl-methionine on growth performance and carcass characteristics in meat ducks
Animal Feed Science and Technology 116(2004)151-159，-0001，（）：
An experiment was conducted with meat ducks to determine if betaine could replace methionine in a methionine-deficient diet. In order to avoid the effects of betaine as a methyl-group donor or as an osmoprotectant or coccidiostat enhancer, sufficient amounts of methyl-donating compounds were added and clean conditions were used to reduce the coccidiosis challenge. A total of 576-day-old female meat ducks were fed one of four diets in a 2 (0 and 0.5g betaine/kg)
