Abstract

An experiment was conducted to investigate the effects of feeding fresh cassava roots on the performance and carcass quality of pigs raised from $15{\pm}1kg$ to 85 kg live weight. Fresh unpeeled cassava roots were chopped into chips and offered separately along with a protein concentrate made up of copra cake and meat and bone meal, and a local mineral-vitamin premix. Commercial pig grower and finisher diets served as control. A total of 24 pigs were used in an incomplete randomized split-plot design experiment. Pigs fed fresh cassava-based diet grew as fast, 0.78 vs 0.77 kg/day, and were as efficient, 3.74 vs 3.77 in converting feed into body weight gain as those fed the commercial control diet. Similarly, there were no differences in carcass quality measured in terms of dressing percentage, 77 vs 77; backfat thickness, 2.76 vs 2.78 cm; loin eye muscle area, 29.2 vs $29.1cm^2$ and in the relative proportions of the different carcass cuts between the two dietary treatments. The use of fresh cassava along with the protein and the local mineral-vitamin premix however, resulted in lowered total feed cost and cost per unit of live weight gain. It is concluded that fresh cassava roots can be fed along with copra cake, meat and bone meal protein concentrate and a local mineral-vitamin premix to fattening pigs with no adverse affects on performance and carcass quality.
