    Resumen: Para determinar los factores no genéticos que influyen en las características de crecimiento de corderos Dorper en condiciones intensivas se registraron 990 pesos al nacimiento (PN) y 851 pesos al destete de una unidad de producción de ovejas entre 2006 y 2010. Se analizó el efecto del año, estación de nacimiento, tamaño de camada, edad de la madre y sexo de los corderos. El año de nacimiento afectó (p < 0.05) el peso al nacer pues fue más elevado en verano y más reducido en invierno y primavera. Los machos fueron más pesados (p < 0.05) al nacimiento y al destete y las tasas de crecimiento pre-destete fueron mayores que en las hembras (p < 0.05). Las ovejas primíparas produjeron crías más livianas (p < 0.05) al nacimiento y destete que las ovejas pluríparas. Se concluyó que diversos factores ambientales tuvieron un importante efecto en las características de crecimiento de corderos Dorper.

    Abstract: The objective of this study was to determine the non-genetic factors which affect growth traits in Dorper lambs under intensive conditions. Nine hundred and ninety birth weight records and 851 weaning weight data from a commercial sheep farm were used. A model containing the effects of year of birth, season of birth, litter size, dams' age and gender was used for identification of factors affecting growth traits. Birth weight was highest (p < 0.05) in summer and lowest in winter and spring. Male lambs excelled females in birth weight, weaning weight, and average daily gain. Young dams produced offspring with a lower (p < 0.05) birth weight and weaning weight than older ewes As a conclusion, important influences of environmental factors on growth traits were identified for Dorper lambs.
