Abstract
The aim of this study was to evaluate the productive performance, carcass traits and meat quality under two rearing system of Jamuna basin lambs. Twenty selected lambs were divided into two treatments like T1 (grazing) and T2 (stall feeding) having ten lambs per treatment. Data was analyzed with unpaired t-test along with GLM procedure of SAS statistical packages. Traits evaluated were carcass traits, proximate components viz. dry matter (DM), crude protein (CP), ether extract (EE) and ash, physicochemical (Ultimate pH, cooked pH, cooking loss, drip loss, water holding capacity-WHC), sensory analysis (color, flavor, tenderness, juiciness, overall acceptability) and instrumental color value (L*, a* and b*). Average daily gain (ADG), hot carcass, skin, viscera, head, pluck, neck, heart, lung, and spleen wt. were found significantly differed (p<0.05) in both treatments. Dressing% and EE% was significantly (p<0.001) higher in grazing than stall feeding. Instrumental color values CIE L*, a* and b* were found significantly higher (p<0.001) in grazing. It may be concluded that grazing group had positive effects on ADG, carcass traits, proximate components, physicochemical, sensory evaluation and instrumental color value in Jamuna basin lamb.
