    Substitution of 0 and 10% of a commercial feed with breadfruit (Artocarpus altilis) meal in the diet for grower pigs was evaluated. Forty six pigs (23 females and 23 intact males) with an average initial weight of 26.5±1.1 kg, were allotted by sex and weight, in 12 pens (3-4 pigs/pen), until reached a final slaughter weight of 73.4±5.9 kg. Growth characteristics, carcass traits and pork quality were analyzed in a one way arrangement, with a 2x2 factorial, for the fixed effects of 0 vs 10% of breadfruit meal and gender. The substitution with 10% of breadfruit meal in the diet, did not significantly affect (P>0.05) average total weight gain (48.3 vs 48.7±1.2 kg), average daily weight gain (826 vs 764±30 g), average daily intake per pig (2.4 vs 2.3±0.1 kg) or feed efficiency (0.34 vs 0.33±0.02) for the pigs consuming a diet with 0 vs 10%, respectively. Duration of experimental period was significantly higher in the animals consuming 10% of breadfruit meal (63.91 vs 58.59±1.55 days, for 10 vs 0% of breadfruit meal, P≤0.05). No differences were found for carcass traits or pork quality, associated to breadfruit meal intake. No significant differences were found between females and intact males for growth characteristics, carcass traits or pork quality. Only the shear force in raw pork was greater for intact males compare with females (4.26±0.51 vs 3.22±0.45 for males and females, respectively P<0.05). According to the results obtained in the present investigation the substitution with 10% of breadfruit meal in the diet of growing pigs can be an effective alternative ingredient for swine diets in Puerto Rico.
