105 Mediterranean adult buffalo cows raised in the provinces of Caserta and Salerno were studied.

Abstract

105 Mediterranean adult buffalo cows raised in the provinces of Caserta and Salerno were studied. For morphological appraisal a series of type traits were measured both by conventional measurement tools (Lydtin bar, tape measure) and by a computerised system of image analysis. Yellow markers were applied on the side regions of some buffaloes to make evident the extremity to be measured. No markers were applied for udder. Data from the two systems were practically overlapping for height records: at withers, pelvis and sternum, with high correlation coefficients, while to a lesser extent for width at pelvis and more for the udder, the percentage differences and correlations showed greater variability due to the objective trouble of skin pigmentation. The fact that in some cases the markers at the extremities of segments to be measured were not applied, may well have affected the above data.
