DETERMINATION OF THE METABOLIC ENERGY VALUE OF KM94 CASSAVA LEAF POWDER ON LUONG PHUONG BROILER CHICKEN

Abstract

The objective of this study is to determine the metabolic energy of KM94 cassava leaf powder with the correction based on the nitrogen retention in chicken body. The study has been carried out on 60 Luong Phuong broiler chickens from 43 to 49 days of age, which have been divided into 2 groups with 30 chickens per group. The chickens of group 1 have been fed a basal diet (BD); those of group 2 have been fed a experimental diet containing 80% of BD + 20% cassava leaf meal; and both diets have been supplemented with 1.5% insoluble mineral. Crude energy and dry matter (DM), insoluble mineral, nitrogen in DM of the diets and fecal of 2 groups have been determined; thence, the metabolic energy of two diets and cassava leaf meal has been calculated. The results have shown that metabolic energy values of 1kg DM and 1 kg cassava leaf meal with 90.39% DM content have been 2150.5 kcal and 1943.8 kcal respectively.
