| description | Studies on cactus carried out mainly in Mendoza plain, Argentina, and in other country
areas were reported. Variations in nutrient contents with three cladode age classes were
examined for seven Opuntia forage clones. For all age classes combined, clones showed
high organic matter: 84.4%, in vitro organic matter digestibility: 78.9% and low crude
protein (CP) content: 4.0%. High doses of fertilizer almost doubled the mean CP content
of the cladodes from O. ficus-indica (L.) Mill. x O. lindheimerii Engelm. cross when it was
compared with the treatment in which no fertilizer was added (7.8 and 4.3%, respectively).
The response to fertilization at the highest application rate was near 4-fold increase over
the biomass of the zero fertilization treatment, 3.2 to 12.7 kg DM plant-1.
Of this cross, clone 42 produced a dry matter (DM) biomass of 40 t DM ha-1 in
4 years with a total of 625 mm rainfall which is the greatest DM production recorded
to date for such a low rainfall. O. spinulifera Salm-Dyck f. nacuniana Le Houér. appears
to be the most promising species for forage production in areas with extremely cold
winters. Clones 46, 80, 83, 89 and 94 had zero frost damage. Economic analysis of
Opuntia plantations and the use of cactus for replacing corn in small ruminant diet
were included. The cost-benefit relationship of using pre-emergent herbicides on
biomass production and fertilizer application on biomass production and protein
levels were analyzed. The cactus/corn cost relationship indicated the possibility of
replacing corn by cactus in small ruminant diet. |

Se informan las conclusiones de los estudios realizados principalmente en la llanura de Mendoza, Argentina, y en otras áreas del país. Las variaciones en los contenidos de nutrientes en tres clases de edad de cladodios se examinaron para siete clones forrajeros de Opuntia. Para todas las clases de edad combinadas, los clones mostraron altos valores de materia orgánica: 84,4% y digestibilidad in vitro de materia seca: 78,9% y bajo contenido de proteína bruta (PB): 4,0%. Altas dosis de fertilizante casi duplicaron el contenido medio de PB de los cladodios del cruzamiento entre O. ficus-indica (L.) Mill. y O. lindheimerii Engelm, cuando el mismo fue comparado con el tratamiento en que no se agregaron fertilizantes (7,8 y 4,3%, respectivamente), mientras que la biomasa se incrementó en aproximadamente 4 veces respecto del control no fertilizado (3,2 a 12,7 kg MS planta-1). El clon 42 de este cruzamiento produjo una biomasa de 40 t de MS ha-1 en 4 años con un total de 625 mm de precipitación, la cual es la producción de MS más alta registrada hasta el presente para tal baja lluvia. O. spinulifera Salm-Dyck f. nacuniana Le Houér. Parece ser la especie más promisoria para la producción de forraje en áreas con inviernos extremadamente fríos. Los clones 46, 80, 83, 89 y 94 no tuvieron daño por heladas. Se incluyeron los análisis económicos de las plantaciones de Opuntia y el uso de cactus para reemplazar al maíz en la dieta de pequeños rumiantes. Se analizó la relación costo-beneficio del uso de herbicidas pre-emergentes sobre la producción de biomasa y de la aplicación de fertilizantes sobre la producción de biomasa y niveles de proteínas. La relación de costos cactus/maíz indicó la posibilidad de reemplazar al maíz por cactus en la dieta de pequeños rumiantes. Fil: Grünwaldt, Josefina María.
