    Punga Fish (Pangasius bocourti Sauvage) is a type of skin fish from the Pangasiidae family. Pangasius is currently highly demanded in the world market. The objective of this study was to investigate the effects of slaughter weight on carcass and meat quality of Punga fish. Two hundred and forty Punga fish from a commercial farm were divided into three groups, 80 fish for each group, based on average target body weights of 700, 900 and 1200 g, respectively. Meat quality was investigated in two muscle sections, the dorsal and the ventral fillet. Carcass quality (dressing and fillet percentage) did not change with slaughter weight. Fillet pH measured at 45 min and 24 h gradually decreased from 6.68 to 5.98 and 6.66 to 5.97 in dorsal and ventral fillet, respectively. Drip loss was larger in the dorsal fillet of the groups weighing 900 and 1200 g. The highest fat percentage was found in the ventral section of fish group weighing 1200 g. Thiobarbituric acid reactive substances (TBARS) were increased in every group and meat section with storage. It was highest in the ventral section of the group weighing 1200 g. In addition, a greater collagen concentration was found in ventral than in the dorsal fillet. Otherwise, slaughter weight and muscle section did not have significant effects on thawing loss, moisture and protein percentage.

    The objective of this study was to assess carcass and meat quality of Black Angus × White Lamphun (A×W) in comparison to Black Angus × Holstein Friesian (A×H) crossbred cattle. In this experiment, sixteen Angus crossbred cattle, eight from each crossbred type, were randomly selected at an average age 20-24 month for slaughter under standard condition. Slaughter weight, carcass quality and proportions of commercial prime retail cuts were determined. The Longissimus dorsi muscle (LD) was selected to evaluate meat quality. Carcass yield (proportion of live weight) was higher (P<0.01) with the A×H than the A×W crossbred. No significant differences were observed between A×H and A×W for hot and chilled carcass weight, carcass length, back fat thickness and loin eye area. The A×W crossbred was superior (P<0.05) compared with A×H in chuck, shot rib and sir loin percentage. The lightness (L*) of the LD of A×W was higher (P<0.01) and redness (a*) as well as protein content was lower (P<0.05) than in A×H. Drip loss, yellowness (b*), fat, and moisture content were not significantly different between the two crossbred types. Thiobarbitiric acid reactive substance (TBARS) levels were increased with storage period in every group, but this at a lower level with the A×W. In conclusion, A×W was superior to A×H incarcass and meat quality, with similar carcass weights at lower dressing percentage. So, promoting of A×W, is a promising first step in creating improved genotypes suitable to cover the demands of the livestock industry of Thailand at concomitantly lower production costs for the farmers.
