    Locally produced urea molasses multi-nutrient block (UMMB) are prone to contamination, inadequate mixing, inefficient compaction during moulding due to the manual method of production. A machine for the production of UMMB was designed, constructed and evaluated. It comprised of a mixing and a moulding unit. The performance evaluation of the machine was carried out. The parameters investigated were density, compressive strength, bioyield force, moulding efficiency and drying time. The results were subjected to analysis of variance and Duncan Multiple Range Test. The results revealed that moisture content was significant for all the parameters investigated. Hence, further investigation was conducted to ascertain how these parameters vary at moisture content levels of 20, 30, 40, 50 and 60% (db). It was observed that Density decreased with increase in moisture content. On the average, the machine had highest moulding efficiency of 89.89%, compressive strength of 4.38N/mm2, bioyield force of 47340N, density of 1058.2 kg/m3 and shortest drying time of 6 hours. Full exploitation of the nutritional, industrial and commercial prospects of UMMB as feed supplements in ruminant nutrition is appropriate.

    The performance of a mixing/pelletizing machine is dependent on the right combination of process variables for the formation of biomass feed pellets for livestock. The performance of a mixer/pelletizer was evaluated in terms of bulk density, pelletizing efficiency, throughput capacity, shattering index, compressive strength and drying time of pellets. The process variables were moisture content, binder conditions and mixer speeds. The data obtained from the tests were statistically analyzed. The analysis of variance test showed that the moisture content, binder condition, the interaction between moisture content, mixer speed and binder condition were significant at 5 % confidence limit. Duncan’s New Multiple Range Test showed that levels of the moisture content, binder condition and mixer speed were significantly different at 5 % confidence level. The results revealed that as moisture content increased from moisture content of 20 to 30 % (db), the pelletizing efficiency and the throughput capacity increased and peaked at 26 % (db). The highest throughput capacity of 116.12 kg/h and pelletizing efficiency of 86.7 % were obtained at moisture content of 26 % (db), 0.5 kg of molasses as binder and 800 rpm mixer speed. The highest bulk density obtained was 1118 kg/m3 and the longest drying time of 2 hours 40 minutes at moisture content of 26% (db), binder condition of 0.5 kg and mixer speed of 800 rpm. Above moisture content of 26 % (db), the drying time remained constant at 2 hours 40 minutes without any change. The proximate analysis results revealed that the highest carbohydrate content was 53.16 ± 0.10 %, highest crude protein content was 20.45 ± 0.22 % while the highest crude fibre was 8.44 ± 0.05%. The quality of livestock feed pellets formed would be enhanced by the right choice of process variables.
