Aim of the present study was the evaluation of the effects of adding omega-3 fatty acids to a rabbit diet; as a omega-3 fatty acids source we used DHA-Gold™, obtained from a Schizochytrium microalgae, which contains 17.4% of DHA. Three-hundred Provisal rabbits were divided into 3 groups receiving in the 32 days before slaughter a commercial diet not added (T1) or added with DHA-Gold™ at 0.4% (T2 and at 0.8% (T3). Average daily gain was significantly increased (P< 0,01) by T2 compared to T1 (33.9 vs 32 g/d). Immediately after slaughtering, thigh and loin samples were collected from 8 animals of each group (4 males and 4 females); DHA content of samples was strongly influenced by treatment (19.1, 56 and 87.9 mg/100 g of thigh and 11, 34.4 and 52.8 mg/100 g of loin for T1, T2 and T3, respectively.

Abstract
Aim of the present study was the evaluation of the effects of adding omega-3 fatty acids to a rabbit diet; as a omega-3 fatty acids source we used DHA-Gold™, obtained from a Schizochytrium microalgae, which contains 17.4% of DHA. Three-hundred Provisal rabbits were divided into 3 groups receiving in the 32 days before slaughter a commercial diet not added (T1) or added with DHA-Gold™ at 0.4% (T2 and at 0.8% (T3). Average daily gain was significantly increased (P< 0,01) by T2 compared to T1 (33.9 vs 32 g/d). Immediately after slaughtering, thigh and loin samples were collected from 8 animals of each group (4 males and 4 females); DHA content of samples was strongly influenced by treatment (19.1, 56 and 87.9 mg/100 g of thigh and 11, 34.4 and 52.8 mg/100 g of loin for T1, T2 and T3, respectively.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
