Influenza di diverse fonti energetiche sulle caratteristiche produttive di agnelli in accrescimento in diete a base di girasole

The research was carried out in order to investigate the effect of different energetic sources on productive performances and carcass characteristics of lambs when sunflower meal was the main protein source. For a 50 days period, starting from 50d of age, 25 male Apennine lambs were fed on five different pelleted diets, based on sunflower meal, and five ratios of maize and barley (100/0, 75/100, 50/50, 25/75 and 0/100). No significant differences in productive performances and carcass characteristics were found among the five diets.
