Research on diet effects on buffalo meat quality may be critical to assess its possible consumption benefits in human nutrition. This study investigated, in growing buffalo bulls, the effects of two diets differing in total fat content and fatty acid profile on the activity and gene expression of Stearoyl-CoA Desaturase (SCD) in the adipose tissue and on meat quality. Twenty buffalo bulls, 6 months old, were randomly assigned to the two dietary treatments until slaughtering (about 400 kg body weight). No significant difference between the groups was observed for chemical composition, fatty acid profile and CLAs content of Longissimus thoracis as well as for the SCD gene expression. Such results seem to be in contrast with similar studies performed on other ruminant species, but confirm that important differences occur between buffalo and bovine species, such as the lower content in fat of buffalo meat. Our results also confirm that specific studies should be performed on buffalo, also in terms of the metabolic pathways activated by different diets.
