Nutrient Bioavailability of Weaning and Growing Pigs fed Composite Cassava Plant Meal Products and Maize

Ogundeji S. T, Adegbaju S.W, Akinfala E. O


The study evaluated the apparent nutrient bioavailability of weaning and growing pigs fed composite cassava plant meal (CPM) products and maize with a view of assessing its nutrient utilization. Three CPM products were developed by mixing sun-dried unpeeled cassava root meal, cassava leaf and tender stem meal at ratios of 2:1, 2.5:1, and 3:1 together. The mixing ratio of leaves to tender stem was 5:1 for the developed products. The tender cassava stem harvested at 5 cm from top of the plant was used. A total of sixteen weaning pigs of weight (10.00 ± 0.57 kg) were randomly distributed to developed CPM products and maize. Sixteen growing pigs of weight (18.50 ± 1.30 kg) were also allotted to the same diet. The animals were kept in the metabolic cage for 7 days and fed 100% of the products and maize. Water was supplied ad libitum while feed was given at 4% of their weight. The feacal samples were collected in a foil paper each day, weighed, oven dried and analyzed for proximate composition. The experiment lasted for forty days. The result of proximate composition showed that maize compared (P < 0.05) with CPM product I. The CPM product I had the lowest (P < 0.05) hydrocyanide (30 ppm). The CPM product 3 pigs had the highest (P < 0.05) ash (93.64%) and dry matter (93.86%) digestibility. At the growing phase, CPM product 3 pigs had the highest (P < 0.05) for most parameters measured. The study concluded that CPM product III was better utilized by both weaning and growing pigs while CPM product I compared favourably with maize for nutrient composition.
