Metabolizable Energy and Nutritional Value of Cassava Pulp in 30 kg and 60 kg Pigs

Abstract

The objectives of this study were to determine the nutritional value digestibility and the utilization of cassava pulp in both starter-pig diets and grower-pig diets. The results demonstrated that the percentage of dry matter (DM), crude protein (CP), crude fiber (CF), fat, calcium ash, phosphorus and nitrogen free extract (NFE) of cassava pulp were 10.40, 2.36, 16.06, 0.26, 4.59, 1.11, 0.06 and 66.33%, respectively and that cassava pulp had a gross energy of 4,178 kcal/kg. Eight barrows of 30 kg body weight were divided into 2 groups. Each group was randomly assigned to two experimental diets for two periods at 30 and 60 kg of body weight, respectively. The experimental diets were: control groups (without cassava pulp); and experimental groups with cassava pulp at 10 and 20% for the 30 and 60 kg body weights, respectively. The availability of DM, CP and CF in the starter diet that consisted of 10% of cassava pulp was 70.96, 64.45 and 62.71%, respectively. The availability of DM, CP and CF in the grower diet which consisted of 20% of cassava pulp was 72.83, 69.63 and 65.97%, respectively. The metabolizable energy of cassava pulp in the starter and grower diets was 2,553 kcal/kg and 2,767 kcal/kg, respectively. The results of this research suggested that cassava pulp can be used as an energy source to replace other raw materials in starter-pig and grower-pig diets.
