Sažetak
The Croatian Spotted goat is an indigenous breed which represents the major part of the goat population in Croatia. It is bred primarily
for kid meat production in extensive pastoral systems. The aim of this study was to determine the slaughter and carcass traits
of Croatian Spotted goat kids, as well as the effect of sex and slaughter weight on those traits. For that purpose 90 Croatian Spotted
goat kids (34 males and 56 females) were slaughtered. According to slaughter weight, the kids were divided into two test groups:
group I (average slaughter weight 21.5 kg) and group II (average slaughter weight 26.2 kg). The kids were slaughtered and processed
in authorized abattoirs. Following slaughter, hot carcasses and non-carcass components were weighed. Also, the following body
dimensions were measured: carcass length, chest width, chest depth, hind limb length and buttock width. Data were analysed using
the general linear model (GLM) procedure of SAS statistical software. Male kids were slightly heavier at slaughter (P>0.05), but had a
statistically significantly (P<0.01) lower dressing percentage than female kids (47.32: 48.79%). The carcasses derived from male kids
were more developed than those from female kids, i.e. they had significantly deeper chest (P<0.01) and longer hind limbs (P<0.05).
Kids of greater slaughter weight had heavier carcasses (P<0.01) and non-carcass components than lighter kids as well as a lower dressing
percentage of hot carcass (P>0.05). Except for buttock width, all carcass measurements of kids of greater slaughter weight were
statistically significantly greater (P<0.01).
