Feed sorting behavior and performance of Argentinian Creole, Braford and crossbred steers during the growing and fattening phases
Local Latin American cattle breeds are considered highly adapted to grazing systems in harsh environments, but their potential in more intensified beef production systems, particularly when compared to imported breeds, is still a matter of debate.

| description | Local Latin American cattle breeds are considered highly adapted to grazing systems in harsh environments, but their potential in more intensified beef production systems, particularly when compared to imported breeds, is still a matter of debate. Argentinian Creole (CRA), Braford (BRA) and Creole x Braford (CXB) steers were evaluated in the growing (Experiment 1) and fattening phases (Experiment 2). In Experiment 1, 12 animals from each genetic group were allocated after weaning to four pens and fed a total mixed ration for 57 days. In Experiment 2, six 17-month old steers of each genetic group were allocated each to a single pen and fed a high concentrate diet for 55 days. Several traits associated with animal performance, feed intake and feed sorting were recorded. Experiment 1: CRA had lower daily weight gain than the other two groups (P<0.01) and also lower feed conversion ratio than BRA (P<0.01). BRA tended to sort against long particles (> 19 mm, BRA < CXB, P = 0.03) preferring short particles (4 - 8 mm, BRA > CRA = CXB, P = 0.06). Experiment 2: CRA had lower initial body weight (P < 0.01) and the difference with BRA was maintained at the end of the experiment (P<0.01). CRA had lower initial and final back fat thickness (P < 0.01) but initial and final rib eye area did not differ among groups. Feed sorting was similar among groups (P≥0.21). Considered overall, CRA steers performed poorly compared to BRA and CXB under unrestricted feeding in both experiments. |

Las razas autóctonas latinoamericanas se consideran muy adaptadas a sistemas pastoriles en ambientes adversos. Sin embargo, su real potencial de producción en sistemas más intensificados y en particular en comparación con razas exóticas introducidas es todavía tema de debate. Se evaluó el desempeño de los novillos Criollo Argentino (CRA), Braford (BRA) y Criollo x Braford (CXB) en las etapas de crecimiento y engorde intensivo (Experimento 1 y Experimento 2, respectivamente). En el Experimento 1, 12 animales de cada grupo genético se asignaron a cuatro corrales y se alimentaron con una ración totalmente mezclada durante 57 días. En el Experimento 2, seis novillos de 17 meses de edad de cada grupo genético se alojaron en corrales individuales y se alimentaron con una dieta concentrada durante 55 días. Se evaluó el comportamiento productivo y la selección de dieta. Experimento 1: CRA tuvo una ganancia diaria de peso más baja que los otros dos grupos (P <0.01) y su conversión (kg/kg) fue menor que BRA (P<0.01). Se observaron diferencias para seleccionar partículas largas (>19 mm, BRACRA y CXB, P=0.06). Experimento 2: el peso vivo inicial de CRA fue más bajo que en BRA y CXB (P<0.01) y la diferencia con BRA también fue significativa al final del experimento (P<0.01). CRA tuvo menor espesor de grasa dorsal (P<0.01). El área inicial y final del ojo de bife fue similar entre grupos en ambos experimentos. La clasificación de las partículas en alimento fue similar entre grupos (P≥0.21). Todos los resultados sugieren que CRA tuvo un desempeño productivo inferior a BRA y CXB en ambos experimentos.
