Abstract
The objective of the present study was to compare in vita performance and carcass characteristics of Bergamasca and Suffolk lambs of 90 days of age. Bergamasca (15) and Suffolk (15) male lambs, originated from single and twin births equally represented, were weighed twice a month. Lambs were slaughtered to evaluate post-mortem characteristics and EUROP conformation score. Suffolk and Bergamasca lambs of 90 days of age produced carcasses with good quality; Suffolk had more compact carcasses than Bergamasca lambs whereas they showed higher percentage of intermuscular fat deposit. The results suggested that the two breeds raised with the forage-based feeding system could produce carcasses of good quality.
