Evaluation of the Crude Protein Content of Three Forage Species: Super Napier (Pakchong), Alfalfa (Medicago sativa) and Boma Rhodes (Chloris gayana)

Abstract

Protein is an extremely important component in animal feeds. It is required on daily basis for body condition maintenance, lactation, growth and reproduction. It can contribute to 10-20 percent of the total energy content of an animal diet. The aim of this study was to investigate and compare the percentage composition of protein content for the three important pasture grass samples within the University of Eldoret Farm. A purposive sampling method was used to collect Lucerne, Super Napier and Boma Rhodes from the University of Eldoret farm. Grass samples were digested using concentrated sulfuric acid in the presence of copper sulfate and potassium sulfate as a catalyst. Sample analysis was done using UV-VIS spectrophotometer and the data analyzed using one-way ANOVA for test of significance. The protein content values obtained were; Lucerne 21.9585%, Super Napier 15.2%, Boma Rhodes 6.79%. The results indicated that there was a significance difference (p<0.05) in the levels of protein content between the three selected green pastures at 95% confidence limits. Therefore, farmers should consider integrating Lucerne and super Napier in their animal feeds as Lucerne acts as a supplement while Super Napier provides the necessary nutrients required.
