The present work has set out to evaluate the effect of nutrition on growth and somatic characteristics of the meat quantity and quality of different Veneto breeds. The trial began in July 2010 at the facilities of the Agrarian Experimental "L. Toniolo" of the University of Padua, and followed a pattern "3 x 3 x 2": 3 races, 3 diets, two sexes. Were in fact used male and female lambs of three breeds Veneto: the Foza (Vicenza), the Alpagota (Belluno) and Brogna (Verona), raised on pasture or in tie stalls with feed consisting of hay and dry feed or again, with the same power supply with integrated dry-conjugated linoleic aci(CLA). At the end of the fattening cycle, which lasted a total of about four months (120 days), the animls where slaughtered at ' average age of about 225 days and an average weight of about 30 Kg. With these animal data were obtained infra-vitam (biometric measurements) and post-mortem at the slaughterhouse and in the laboratory (TARE slaughter weights of the cuts, yield, cooking loss and drip), which were collected, compared and analyzed using SAS software (GLM procedure). The lambs bred Foza, clearly higher than the somatic level than the average of those of race and Alpagota Brogna also ticked slightly higher yields. Differences were evident even among Alpagota and Brogna: it has indeed pointed somatic measurements, BCS (both initial and final) and a yield higherthanall'Alpagota. The differences between males and females are the result of a normal sexual dimorphism. Males were on average higher in all measures of somatic and final slaughter weight, although females had much higher yields. There were no significant differences between diets particularly dry. The CLA is thus not have any input either quantitatively or qualitatively. The emergence highly significant differences between the lambs raised on pasture and those kept dry. The subjects raised on pasture have pointed somatic measures, weights and final BCS higher than those of other entities. They also provided carcasses with higher yields of over 4 percentage points, and cooking loss of 2.5 percentage points lower than in animals reared dry.
