Growth traits in Blanco Orejinegro creole cattle and environmental effects responsible for their variation.

The study of the traits involved in the growth and the environmental effects that are responsible for its variation in Blanco Orejinegro (BON) cattle is important to stimulate its breeding and prevent its extinction. The objectives of this work were to characterize the growth traits of BON cattle and to determine the influence of some environmental factors on these variables. Information from 3218, 2264, 496, 2287, 325 and 408 records was verified for birth weight (BW), weaning weight (WW), and yearling weight (YW), average daily gain at weaning (ADG), time to reach 120 kg (T120) and time to reach 60 % of the adult weight (T60 %), respectively. ANOVAs were performed to determine the influence of the factors calving number (CN), sex, season, age at weighing and contemporary group (CG). The mean values were 31.8 kg, 201.9 kg, 230.5 kg, 0.645 kg/day, and 136.4 and 541.1 days, for BW, WW, YW, ADG, T120 and T60 %, respectively. The effects CN (except for T60 %), CG, sex and age at weighing were significant, but not the season. On average, animals born from cows with CN 1 or 7 were significantly lighter; the CG showed to be a source of important variation due to the interaction between sex-year-herd or herd-year. These results show that some environmental factors affect growth in the BON population and that this is a breed with good productive potential.

El estudio de las características involucradas en el crecimiento y los efectos ambientales que son responsables de su variación en ganado Blanco Orejinegro (BON) son de gran importancia para estimular la cría y evitar su extinción. Los objetivos de este trabajo fueron describir las características de crecimiento en ganado BON y determinar la influencia de algunos factores ambientales sobre estas variables. Se comprobó información de 3218, 2264, 496, 2287, 325 y 408 registros para peso al nacimiento (PN); peso al destete (PD); peso al año (PA); ganancia diaria de peso al destete (GDP); tiempo para alcanzar 120 kg (T120); y tiempo para alcanzar 60 % de peso adulto (T60 %), respectivamente. Se realizaron ANAVAs para determinar la influencia de los factores número de parto (NP), sexo, época, edad al pesaje y grupo contemporáneo (GC). Las medias fueron 31.8 kg, 201.9 kg, 230.5 kg, 0.645 kg/día y 136.4 y 541.1 días, para PN, PD, PA, GDP, T120 y T60 %, respectivamente. Los efectos de NP (excepto para T60 %), GC, sexo y edad al pesaje fueron significativos, pero no la época del año en que se hizo el pesaje. En media, se encontró que animales hijos de vacas con NP 1 o 7 fueron significativamente más livianos; el GC mostró ser una fuente de variación importante debido a la interacción entre sexo-año-hato o hato-año. Estos resultados muestran que algunos factores ambientales afectan el crecimiento en la población BON y que esta es una raza con buen potencial productivo.
