A cafeteria test in calves, sheep and goats was developed to determine through consumption of dry matter and coeficient of preference the palatability of these fruits as a feed source. Crude protein and neutral and acid detergent fiber contents were higher in the A. cochliacantha fruit (p < 0.001) with 11.1, 55.0 and 38.3 %, respectively. Total phenols were higher (p < 0.001) in A. farnesiana fruit with 39.7 %. The IVDMD and IVOMD were greater (p < 0.001) in P. dulce fruit with 57.7 and 35.6 %, respectively. The P. dulce fruit was more palatable (p < 0.0001) for calves and those of A. cochliacanta for sheep and goats (p < 0.05). It is concluded that palatability was higher for A. cochliacanta and P. dulce fruits due to their chemical composition.

Eighteen sheep F1 (Pelibuey × Dorper) with live weight of 20.4 ± 1.8 kg were randomized into three groups of 6 animals each. Treatments were basal diet with nutritional blocks without fruit (T0 = control), with 30% of fruits of A. farnesiana (T2) or with 30% fruits of A. cochliacantha (T3) on a dry matter basis. Dry matter intakes of nutritional blocks (NB), corn stover (CS), concentrate and total consumption were measured. Moreover, the daily weight gain (DWG), feed conversion (FC), apparent digestibility of nutrients as the organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (FDA) were also measured. Intake of NB were higher (p > 0.001) in sheep of treatments T1 and T2; however, CS intake and total dry matter intake was...

Se utilizaron 20 cabras multirraciales en producción de leche con una producción promedio de 1.5 L de leche, y fueron divididas en 2 grupos (n=10 c/u) homogéneas en cuanto a peso vivo y condición corporal. Un primer grupo (Tratado) fue suplementado con 150 g de PCaf más 150 g de concentrado comercial (17% PC, 1.5 EM) y 2% de melaza del total de la ración, mientras que un segundo grupo (Control) recibió 100 g de concentrado comercial. El periodo de estudio fue de 21 días. La suplementación de los animales fue individual por la mañana (8:00 am) durante todo el periodo experimental. Se evaluaron las siguientes variables: peso vivo (PV), condición corporal (CC), pro...
