Nutritive Value of Urea Molasses Block Containing Acacia Erubescens or Dichrostachys cineria as Natural Protein Sources

Authors : A.A. Aganga and C.B. Motshewa

Abstract: This study was aimed at developing Molasses-urea Blocks (MUB) for purposes of providing supplementary feeding that will supply crude protein and minerals to ruminant livestock during drought periods. In order to accomplish this, urea, molasses, sorghum bran, Acacia erubescens or Dichrostachys cineria as local browse trees in Botswana and dicalcium phosphate as a commercial mineral ingredient, salt and cement were used. Cement was used as a cold binder and roughages such as grass hay or Lucerne were also used in some MUB and their nutritional contents were compared to those containing browse plants. Dry matter, crude protein and mineral contents were analyzed using proximate analysis. All the 4 blocks hardened within 5-7 days and yielded dense blocks. MUB containing Acacia erubescens and Lucerne had higher nutrient contents than MUB containing Dichrostachys cineria and grass hay. All the macro mineral contents were within the normal range required for maintenance by grazing animals. Dry Matter (DM), Crude Protein (CP), Ash, Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Acid Detergent Lignin (ADL) and in vitro DM digestibility differed (p< 0.05) between MUB types evaluated. All the MUB had crude protein content varying from 11.83-26.58%. Average mineral content (%) of all MUB were 16.33, 9.35, 5.38, 1.09 and 0.27 for P, Ca, Mg, Na and K, respectively. Also some of the trace minerals Fe (%), Mn and Zn (ppm) had average values of 0.098, 0.018 and 0.002, respectively.
