The quality of the commercial feeds available is highly variable with protein content ranging from 20 to 30% (mean 25.8%) (table2), whilst that of farm-made feeds ranged from 17 to 26% (mean 21.6%) (authors' observations). Detailed studies conducted on the quality of commercial and farm-made feeds have shown that, contrary to the popular belief, the moisture content of the two types of feeds is not significantly different (p>0.05), varying from 8 to 10% .
