Sažetak

The aim of this study was to determine slaughter characteristics, carcass traits and colour value and pH indicators in muscular tissue of ewes, rams and wethers of Travnik Pramenka sheep. For that purpose, 69 mature sheep’s were slaughtered at three sex categories: 25 ewes, 22 rams and 22 wethlers. Animals were slaughtered in authorized abattoir, and carcasses were submitted to standard procedures of processing, after that all internal organs were weight and skin with lower legs and carcass weight were determinated. After that carcass measurements were taken, pH values (pH45 and pH24) were determined in M. longissimus dorsi (MLD) and colour indicators in M. ractus abdominis (MRA) and M. semitendinosus (MS). Significant (P<0.01) differences were determined in slaughter weight among researched categories (ewes 59.47 kg; rams 71.19 kg; wethers 68.05 kg), that were significantly (P<0.01) reflected on hot and cold carcass weight. The weight of certain internal organs were not significantly different, except liver weight that was the largest (P<0.01) in rams. pH values (pH45 and pH24) of MLD were not significantly different among researched categories. Lower L* and significantly (P<0.01) higher values of a* and b* indicators of colour MRA were determined in ewes then in rams and wethlers. Also, the value of L* indicator of MS was the lowest (P<0.01) in ewes, while a* value was the highest (P<0.05) in wethlers. b* value was significantly different between all researched categories (P<0.05 and P<0.01). Equal values were determined for carcass length, depth and width, while the hind limb length was significantly different between researched categories of Travnik Pramenka sheep.
