Nutritional composition of rice distiller dried grain with solubles as a feed source for livestock

Abstract

A research study was carried out to assess the nutrient composition, calcium, phosphorus, salt and urea content in high protein Rice Distiller Dried Grain with Solubles (rDDGS), a byproduct of the ethanol manufacturing process. Six (6) samples were procured from various sources for the study. The proximate composition (% DM) in terms of crude protein (CP), crude fibre (CF), ether extract (EE), nitrogen-free extract (NFE), and total ash (TA) was 66.49±0.61, 3.95±0.09, 2.20±0.09, 20.04±0.39, and 7.32±0.33%, respectively. The acid insoluble ash (AIA) content was 5.20±0.24 percent. The calcium and phosphorus content in rDDGS were 0.15±0.02 and 0.61±0.01% respectively. The percentage of salt and urea content in high protein rice DDGS were 0.22±0.01 and Below Detectable Level (BDL) of 0.1. Hence, rice DDGS can be used as a potential protein source in livestock and poultry diets.
