Production performance were measured on lambs fed with feed containing grape seed flour; weight gain, feed consumption and slaughtering parameters were recorded. 24 "Gentile di Puglia" lambs were divided into four homogeneous groups as regards weight; from the age of 50 days they were fed for a further 63 days on complete feeds in pellet form. The feeds contained 0, 10, 20 or 30% grape seed flour. The feeds containing this by-product gave productive responses comparable to, or even better than, those obtained without by-product . A content of 10% grape seed meal in the feed produced weight gains and final live weights greater (P<0.05) than those produced by the control feed (261 g/d vs. 222 g/d and 34.016 kg vs. 31.533 kg). The use of up to 20% grape seed meal gave feed conversion indexes similar to those obtained using the control feed. Slaughtering data, pH measurements, dissection data and meat chemical composition were not influenced by the type of feed. Interesting findings were obtained from the fatty acid composition, which showed that increasing levels of inclusion of grape seed flour in the feed decreased saturated fatty acids, increased unsaturated fatty acids and improved dietary characteristics of the meat with the best indices of atherogeniticy and thrombogenicity.

Among the peneids, Marsupenaeus japonicus, a cold-temperate species, carnivorous, is the mostly cultured prawn in Italy and in the Mediterranean Sea basin, thanks to the good adaptability to the temperature and salinity variations, to the good resistance to the manipulations (better resistance out of water), to its appreciate nourishing qualities and to the good growth rate (Lumare, 1998).Whereas the literature on cultured fish fillet is rich (Gjedrem, 1997; Lanari et al., 1999; Parisi et al., 2003), few are the information about the shrimp meat quality traits.Therefore, the present work aimed at typifying the variations of the meat quality characteristics in shrimps from semi-intensive (supplemented with an artificial diet) or extensive rearing systems
