Two experiments were designed to study the effect of dehydrated molasses powder on feed digestibility, rate and efficiency of gain and carcass composition of growing pigs. The inclusion in the ration of 10 and 20% dry molasses powder increased N-retention by 4 and 13.2 % respectively while only small changes occurred in apparent digestibility of N and in the digestible and metabolizable energy content of the ration. Although control pigs grew faster, utilized their feed better and had more lean and less fat in their carcasses the differences occurring were small and not statistically significant.
