Effects of pasture on carcass composition in Cinta Senese pig

Abstract

The trial was performed to investigate on the effects of different periods of grass pasture in fattening Cinta Senese pigs; growth performances, carcass characteristics and meat quality were studied. Control group was reared in paddock and fed concentrate, while experimental group grazed on grass pasture with an integration of 1.4 kg/pig/d of concentrate. Initial live weight was not different between the two groups and individual weights were periodically recorded. Animals were slaughtered from 36 to 160 days from the trial beginning. Carcass weight, body measures, backfat thickness, pH45 and pH24 were recorded. After 24 hours of refrigeration, each carcass was dissected into lean, fat and bone cuts. Results didn’t show differences between the two groups, revealing that Cinta Senese pigs can profitably utilize pasture on grass even in fattening period.
