LEYVA, Coralia; ORTIZ, A; MARTI, O  e  VALDIVIE, M. Inclusion of meal from Artocarpus altilis fruit in diets for pre-fattening pigs. Pastos y Forrajes [online]. 2013, vol.36, n.4, pp. 468-473. ISSN 0864-0394.

In the Baracoa and Maisí municipalities, Guantánamo province, the bromatological composition of the meal from Artocarpus altilis (breadfruit) fruit and its inclusion in diets for pre-fattening pigs was evaluated. Forty eight Yorkland x Duroc hybrid animals, 33 days old and with 6 kg of live weight as average, were used. The design was completely randomized, of simple classification and with four replications, each of them constituted by three animals. The treatments consisted in: a control in which only concentrate feed, composed by corn and soybean meal, was consumed (T1); inclusion of 10 % meal from A. altilis fruit (MFBT) in the concentrate as substitute of corn (T2); 20 % of MFBT (T3) and 30 % of MFBT (T4). It was found that the meal from A. altilis fruit is a source rich in starch, sucrose, glucose and fructose; in addition, it is very poor in lipids (0,71 %) and has a moderate protein (5,80 %) and fiber content (7,74 %). The tannin and saponin concentrations were high. Equal values of viability (100 %) and intake (34,5 kg) were obtained in all the treatments. Only the diet that included 10 % of the MFBT did not differ significantly with regards to the control in the other evaluated indicators. The economic impact obtained with this diet allowed to save US $23,19 per ton of live weight produced as compared with the control. To include 10 % of the MFBT as maximum limit in the diets for pre-fattening pigs is recommended.
