Economics and effect of replacing wheat offal with cassava peel meal on growth performance, nutrient digestibility of growing pigs

This study was carried out to determine the feeding value of Cassava Peel Meal (CPM) as replacement for wheat offal in growing pigs' diets. Five treatment diets were formulated by replacing wheat offal with CPM at 0, 25, 50, 75 and 100% for treatments T1, T2, T3, T4 and T5, respectively. A tota...

description This study was carried out to determine the feeding value of Cassava Peel Meal (CPM) as replacement for wheat offal in growing pigs' diets. Five treatment diets were formulated by replacing wheat offal with CPM at 0, 25, 50, 75 and 100% for treatments T1, T2, T3, T4 and T5, respectively. A total of 75 growing pigs of large white breed were allotted on weight equalization basis into the five dietary treatments with 15 pigs per treatment and 3 pigs per replicate in a completely randomized design. The pigs were allowed to acclimatize for two weeks before the commencement of the study which lasted for 14 weeks. Results indicated that wheat offal contained 16.25% crude protein (CP), 18.86% crude fibre (CF) and 1.18% ether extract. The values were higher than cassava peel meal's 5.18% CP and 15.18% CF and was lower than 1.99% ether extract. The 25, 50, 75% CPM significantly (p0.05) difference in feed intake.
