Abstract

This research aimed to evaluate the effect of diet lipid source and sex on meat quality and lipid fatty acidcomposition in fattening lambs. Twenty-eight Gentile di Puglia breed lambs were weaned at about 35 days of ageand included in a 2×2 factorial scheme of two sexes (males vs. females) and two diets (soybean meal vs.extruded linseed).Lambs fed linseed diet had a higher carcass fat score than lambs fed soybean diet. The linseed diet gave ahigher (P < 0.05) PUFA content and a lower n-6/n-3 ratio than the soybean diet. The females had lower(P < 0.01) daily growth rates, higher (P < 0.01) feed conversion ratio, greater (P < 0.01) dressing percentagesand fatter carcasses (P < 0.01); while, the meat of the males showed higher values of final pH, brightnessand yellow index. The males showed a lower PUFA n-6:n-3 ratio in comparison with females.In conclusion, the diet influenced fewer variables compared to sex. The fatty acid composition of meat resultedmore satisfying in males than females.
