Three CPMs products were developed from cassava variety (Tropical Manihot Species (TMS) 30572) harvested at 24 months after planting. The different cassava plant parts (sun-dried unpeeled cassava tuber meal, cassava leaf meal and tender cassava stem meal) were mixed at different ratios of 2:1, 2.5:1 and 3:1 while the ratio of the leaves to tender stems was 5:1 across the three CPMs products. The apparent nutrient digestibility of the developed CPMs products by pre-gestation gilts, and the proximate composition, minerals, amino acids, vitamins, fatty acids and apparent nutrient digestibility of CPM-based diets for gravid gilts were determined using standard laboratory procedures. Results showed that CPM products 2 and 3 had higher crude protein and crude fibre digestibility coefficients and were better digested than CPM product 1. The proximate composition of CPM-based diets differed significantly (p<0.05) across dietary groups. The amino acid contents increased with increasing inclusion of unpeeled cassava tuber meal to the CPM-based diets. Also, the Calcium, Phosphorus, Manganese and Chlorine content were influenced (p<0.05) by increasing inclusion of unpeeled cassava tuber meal. The apparent nutrient digestibility of the CPM-based diets was significantly (p <0.05) higher in 100% CPM-based diets and comparable to the value obtained for the group fed maize-based diet. In conclusion, the CPMs products 2 and 3 had comparable nutrient contents as maize meal and the digestibility coefficient of the nutrients in the experimental diets fed to gravid gilts increased with increasing inclusion of unpeeled cassava tuber meal. Cassava plant meal could give comparable reproductive performance when fed to gravid pigs.
