The aim of this study was to determine slaughter and carcass characteristics as well as some indicators of lamb meat quality (pH value and muscle tissue colour). Also, the aim was to determine the influence of sex on slaughter and carcass characteristics and lamb meat quality indicators. For that purpose a total of 32 Marinolandschaf lambs were slaughtered, of which 14 male and 18 female with average age at slaughter of about 100 days. The average slaughter weight of lambs measured immediately before slaughter was 37.09 kg, considering that male lambs had statistically significant (P <0.05) higher slaughter weight than female (38.95 kg : 35.64 kg). Determined average carcass weight of 19.16 kg was almost equal in male and female lambs. Statistically significantly higher dressin percentage (P<0.001) was determined in female (53.57%) than in male (49.46%) lambs. The basic features of the investigated female and male Merinolandschaf lambs are: expressed measures of length, depth and width compared to most lambs present in the Croatian market. The uniformity of male and female lamb carcases was determined based on the investigated meat quality indicators (pH value and colour), except the L* and a* value of colour parameter determined on M. semitendinosus which was statistically significantly higher in male lambs (P<0.001; P<0.01). Ujednačenost trupova muške i ženske janjadi utvrđena je i temeljem istraživanih pokazatelja.
