Abstract: Abstract In the Ethiopia, Prosopis juliflora was introduced in the 1970’s by Ministry of Agriculture in the Awash River basin in the Afar National Regional State (ANRS) of Northeast Ethiopia. The plant rapidly invaded vast areas of a these region. Variety of material has been done on utilization of this plant for different application and benefit including as feed ration. Despite the high content of Nutrition available for the cattle feed, it is less digestible for ruminant animals. Therefore, Thermochemical Treatment methods of processing P.Juliflora to improve its digestibility have been suggested by different researchers. This paper assesses the effectiveness of treatment of Prosopis Juliflora using Sulfurous acid (SO2 + H2O) and was found to have the better potential. The effect of reaction time, concentration of Sulfurous acid, and heat treatment for improving digestibility of Prosopis was investigated. The treatment was efficient that it almost increase the total digestibility of this plant by two fold making it comparative to other commercial roughage feeds. The treatment efficiency of this thermochemical method was increased with concentration of sulfurous acid and cooking temperature. The In-vitro Dry Matter Digestibility was appreciable when reaction time is also longer. Laboratory scale reactor were conducted and showed good result on improving the digestibility of P.Juliflora. The In-Vitro DMD shows a maximum of 70% digestibility under condition of 6% SO2, 120 oC and 2.5 hours reaction time including a 30 minute heating rate.
