Dry Matter and Crude Protein Values of Selected Feedstuffs Used in the Nigerian Livestock Industry

Abstract

This study was carried out to establish the dry matter (DM) and crude protein (CP) for dry brewers spent grain (DBSG), cassava meal (CAM), palm kernel cake(PKC) and groundnut cake(GNC) collected from five locations in Nigeria that could serve as reference values for their utilization in the Nigeria livestock industry. The mean dry matter values ranged from 89.304 ± 0.857% (CAM) to 93.006 ± 0.456% (PKC), with avery narrow coefficient of variation (CV) range of 0.41 – 0.96, indicating that the DM value could serve as reference for the industry. The crude protein (CP) values standardized to 88% ranged from 0.97 ± 0.23 (CAM) to 42.41 ± 6.31 (GNC), with mean values of DBSG and PKC being in between 23.34 ± 1.72 and 13.55 ± 0.62% respectively. The CV across sample values was relatively narrow for DBSG (7.67) and PKC (4.55) indicating that their mean values could serve as areference in the industry. The CV values of GNC (14.87) and CAM (23.31) were however wide indicating that their mean values may not be reled upon. It was concluded that the evaluated feedstuffs were in DM content,the mean CP values recorded for DBSG and PKC could serve as reference values for the Nigerian livestock industry.
