Evaluation of Protein and Mineral Nutrients in Cattle Hide Scraps Used for Treating Children with Kwashiorkor in Bukavu

Abstract

Kwashiorkor is an appalling state of malnutrition that strikes many children under five in developing countries including the Democratic Republic of Congo. Because of poverty, local population is using beef skins hide (cowhide or oxhide) scrapings, named “Nkulo” in Bukavu city, to combat this condition. This study aimed at analyzing quantitatively the content of Nkulo in mineral and protein-energetic nutrients to verify whether it is suitable for such a purpose. Five samples were purchased in different open markets of the city. The protein content was evaluated as total nitrogen by Kjedhal method whereas the mineral content was determined by Atomic Absorption Spectrometer and X-Ray Spectrofluorometer. On average the yield in proteins was 53.5±2.9 percent. The minerals in appreciable concentration were Fe(50mg/100g); Si(19mg/100g); Sb(18mg/100g); Ca(16mg/100g); Sn(13mg/100g); Cr(11mg/100g); Ni(10mg/100g); K(10mg/100g) ; P(5mg/100g/); Ti(3mg/100g); S(1mg/100g); Cu(1/100g); Zn(0.7mg/100g). Other elements were found in less than 0.7 mg/100g. The high concentration in proteins and iron may justify the use of Nkulo for protein linked malnutrition and anaemia. The concentration in heavy metals was inferior to maximal admissible levels. However the quality of storage and packaging should be improved to prevent possible fungal contamination. Local pharmacists and nutritionists are invited to assist in preparing innovative formula.
