The objective of this study is to evaluate the effect of condensed tannins (CTs) distribution using carob pulp in diet on meat and carcass quality and growth performance of kids. Three diets with 0 per cent, 25 per cent, and 45 per cent of carob pulp (C0, C5 and C10, respectively) were distributed to 3 groups of kids from weaning to slaughter at 6 months of age. C5 kids showed highest ADG90-180 and final weight at 180 days (73.33 g per day; 18.50 kg respectively). Meat moisture, fat, pH and water retention showed no variation. However, C5 contains more protein (P less than 0.05).The linoleic acid composition in meat increase with C10 (P less than 0.05). The low intakes of CTs seem to be insufficient to fully protect certain unsaturated fatty acids against biohydrogenation of fatty acids (DFA 67.03 per cent vs 64.91 per cent and 66.54 per cent respectively for C0, C5 and C10, P greater than 0.05). The same result was observed for perirenal fat. Omega 6 and C18:1n9 experienced an increase in meat from goats fed with the C10 diet (P greater than 0.05). Carob use in kids diet is accompanied by an improvement of protein and desirable fatty acids, especially linoleic acid, in meat.
