El kenaf (Hibiscus cannabincus) variedad Vinkat-3, fuente de alimento para vacas lecheras en pastoreo R. García López E. Vinent B. Ortiz María R. González Agrociencias kenaf pastoreo Vacas lecheras producción de leche alimento no convencional Se seleccionaron 20 vacas Holstein comercial, según diseño completamente al azar, en su etapa media de lactación y con una producción potencial de 12 ±1 kg/vaca/d, en dos tratamientos: A) pastoreo de estrella solamente y B) pastoreo de estrella con franjas intercaladas de kenaf (variedad Vinkat-3), para compararlos durante la época de seca (noviembre-abril). La producción de leche se midió cada 15 d en el ordeño de la mañana y la tarde. Se tomó la muestra una vez por mes para determinar los indicadores bromatológicos. Los resultados sugieren mejor producción de leche (11.3 vs 9.7 kg/vaca/d) y energía en leche (30.9 vs 24.6 MJ/d) en las vacas que consumieron el pastoreo intercalado con kenaf, que en las que consumieron el pasto solo. El trabajo sugiere continuar estudios con vacas lecheras en nuestras condiciones de pastoreo y con la variedad de kenaf Vinkat-3. 2004 artículo científico 0034-7485 https://www.redalyc.org/articulo.oa?id=193017793004 es http://www.redalyc.org/revista.oa?id=1930 Revista Cubana de Ciencia Agrícola application/pdf Instituto de Ciencia Animal Revista Cubana de Ciencia Agrícola (Cuba) Num.4 Vol.38
