RESUMEN
Se utilizaron seis ovejas Suffolk y ocho Rambouillet de parto gemelar para determinar
diferencias por raza en el consumo voluntario, en una lactancia en pastoreo continuo en una
pradera de
Lolium multiflorum. La producción fecal se estimó usando 1 g de sesquióxido de
cromo por oveja como marcador externo, administrado en dos cápsulas de gelatina por animal,
una antes y la otra al finalizar el periodo de pastoreo (7:00 y 17:30 h), a partir del cuarto
día posparto hasta los 64 días posteriores a éste. Las muestras de heces se recolectaron de
cada animal vía rectal por tres días consecutivos, los días 18 a 20, 33 a 35, 48 a 50 y 63 a
65 posparto. La digestibilidad
in vitro de la MS del forraje se estimó durante los mismos días
tomando tres muestras manuales diarias de forraje. Con toda esa información se estimó el
consumo voluntario por animal por días y por peso metabólico. Los datos fueron analizados
mediante un diseño completamente al azar y mediciones repetidas. El consumo voluntario,
expresado en kg de MS por animal (Suffolk = 3.28
vs Rambouillet = 2.44) y por peso
metabólico (Suffolk = 0.1045
vs Rambouillet = 0.1422 kg PV
0.75) mostraron diferencias por
raza, siendo menor para las ovejas Suffolk que para las Rambouillet, lo que probablemente se
deba a un mejor desempeño de la raza Rambouillet bajo condiciones de pastoreo.
