The present study was undertaken to study the effect of varying levels of Moringa oleifera leaf meal (MOLM) supplementation on in vitro utilization of concentrate mixtures replacing total crude protein of soybean @ 10,20,30,40 and 50%.The net gas production was significantly increased as the moringa supplementation level increased in the concentrate ration. It was significantly higher in 30% moringa based concentrate and significantly lowest in control concentrate. | In vitro nutritional evaluation and digestion kinetics of concentrates containing varying levels of Moringa oleifera leaf meal supplementation as protein source for goats
