Protein sources in the diets of growing pigs: 2. A comparison between fish meal and carcass meal

Thirty-six weaner Landrace x Large White crossbred pigs were used in an experiment conducted to determine to what extent fish meal can be replaced by carcass meal as a protein supplement in pig growth diets. The experimental treatments consisted of three diets in which fish meal was partially replaced on a protein basis by 0,0%, 5,6% or 11,0% carcass meal. The inclusion of 11,0% carcass meal resulted in a slight reduction in growth rate but in a significant reduction in feed conversion. The physical as well as the chemical composition of the carcasses was unaffected by the treatments imposed.
