This study aimed to identify the optimum level of supplementary feeds on the carcass traits and meat quality of Jamuna basin lambs. Forty selected lambs were divided into four treatments such as T0 (no concentrate supplementation), T1 (1% concentrate feed), T2 (1.5% concentrate feed) and T3 (2% concentrate feed) having ten lambs per treatment. The data were analyzed through Completely Randomized Design (CRD) with SAS software. Hot carcass, dressing percentage, head, leg, neck, loin, heart, and spleen weight were showed significantly (p < 0.05) higher values with increasing concentrate feed. The crude protein (CP), ether extract (EE) and ash values were significantly increased (p < 0.001) except T2 treatment. The ultimate pH was significantly increased except T2 and cooked pH was significantly decreased (p < 0.001) except T3 treatment. Drip loss and cooking loss (CL) % had significantly reduced (p < 0.001) except T3 treatment. The water holding capacity (WHC) % was significantly increased (p < 0.001) except T3 treatment. The score of color, juiciness and tenderness were significantly different (p < 0.001). Flavor and overall acceptability score were significantly increased (p < 0.05) in different treatments. The color values L* and b* had significantly changed (p < 0.001) and a* value was found significantly higher (p < 0.05) in all treatments. Hence, 12 months of aged lambs with 1.5% concentrate feed showed better performances on carcass, nutritional, physicochemical, sensory and instrumental color values to increase the carcass and the meat quality of lambs.

Participation of Marginalized Households in Shrimp Value Chains in Southern Coastal Bangladesh
Md. Mojammel Haque,M. Serajul Islam,Mohammad Ismail Hossain,Md. Wakilur Rahman 연세대학교 빈곤문제국제개발연구원 2021 Asian Development Perspectives (ADP) Vol.12 No.2
The shrimp export industry contributes significantly to Bangladesh’s economy, and is having a positive impact on the livelihoods of many. However, in contrast to small-holder farmers, the role of the shrimp industry in reducing poverty among the most marginalized households, who lack land or access to other resources, has been disappointing. In order to better understand why, the present study was designed to determine the roles of marginalized households in the shrimp value chains of coastal Bangladesh. Both quantitative and qualitative data were collected through field surveys, focus groups and in-depth interviews in the Khulna, Bagerhat and Satkhira districts. We find that about 46% of marginalized households are engaged in shrimp value chains and added some value in each node for an average of seven months a year. Their roles were wild shrimp fry catching and trading, shrimp PL (postlarvae) collection and trading, PL numerating, PL growing-out, shrimp trading, deheading, cleaning, icing and preserving. As laborers, the role of marginalized household members in the governance structure of the value chain was insignificant, and they have limited bargaining power. Nevertheless, they contribution added value at each node of the value chain, and their labor contribution was indispensable to the functioning of the chains.
