Abstract: To study factors affecting birth weight (BW), weight at 30 days and 60 d, data from 917 Columbia lambs were analyzed. Lambs were born in april (N-B) from yearly breeding, or in april-may (A-M), december-january (DJ) and august-september (A-S) from an every eight months breeding program (I-B). Ewes and lambs were grazed on irrigated grass-legume temperate pastures; lambs had access to creep feeding from 15 d of age. Fixed effects in the variance analysis were: ewe age; single or twin birth; sex and year or season of birth. Simple correlations were obtained between BW and weights at 30d and 60d and of these with ewe body condition. The BW (5.7 ± 0.06 kg) and weight at 30 d (15.0 ± 0.17 kg) in I-B were higher (P < 0.05) than in N-B (5.5 ± 0.06 kg and 13.8 ± 0.17 kg), without difference at 60 d (21.5 ± 0.25 kg vs. 21.4 ± 0.24 kg, respectively). Single births and males were always heavier (P < 0.05) from birth to 60 d. Year differences in N-B were not observed at birth or 60d (P > 0.05), but were at 30d (14.7 ± 0.22 kg vs. 13.2 ± 0.18 kg). I-B lambs born in D-J were always heavier (P < 0.05): 6.2 ± 0.08 kg, 5.3 ± 0.10 kg and 5.5 ± 0.09 kg; 16.2 ± 0.22 kg, 14.8 ± 0.27 kg and 13.8 ± 0.25 kg; 22.2 ± 0.33 kg, 21.3 ± 0.39 kg and 20.8 ± 0.36 kg for BW, 30 d and 60 d in D-J, A-M and A-S, respectively. Correlations between weights were always positive (P < 0.05), and only in N-B was there negative correlation between ewe body condition and weight (P < 0.05). Resumen: Para establecer factores que influyen en el peso al nacimiento (PN) a los 30 d y 60 días, se utilizaron los registros de 917 corderos Columbia, producto de un sistema de apareamiento anual (S-A) con partos en abril y uno cada ocho meses (S-I), con partos en abril-mayo (A-M), diciembre-enero (D-E) y agosto-septiembre (A-S), bajo condiciones de pastoreo intensivo en praderas irrigadas de clima templado. Desde los 15 días, los corderos dispusieron de suplemento. En el análisis los efectos fijos incluyeron: Edad de la madre, tipo de parto, sexo y dentro de sistema, época o año. Se realizaron correlaciones lineales entre pesos al nacer 30 y 60 días y la condición corporal de las madres. El PN (5.7 ± 0.06 kg) y a 30 d (15.0 ± 0.17 kg) del S-I fue mayor (P < 0.05) que del S-A (5.5 ± 0.06 kg y 13.8 ± 0.17 kg), desapareciendo la diferencia a 60 d (21.5 ± 0.25 kg vs. 21.4 ± 0.24 kg). Independientemente del sistema, los corderos únicos y los machos fueron más pesados del nacimiento a 60 días que los dobles o las hembras (P < 0.05). El S-A no mostró diferencias entre años en PN o 60 días (P > 0.05), pero sí a los 30 días (14.7 ± 0.22 kg vs. 13.2 ± 0.18 kg). En el S-I, los nacidos en D-E fueron más pesados (P < 0.05) al nacimiento 30 días y 60 días que A-M y A-S (6.2 ± 0.08 kg, 5.3 ± 0.10 kg y 5.5 ± 0.09 kg; 16.2 ± 0.22 kg, 14.8 ± 0.27 kg y 13.8 ± 0.25kg; 22.2 ± 0.33kg, 21.3 ± 0.39 kg y 20.8 ± 0.36 kg, respectivamente) (P < 0.05). Las correlaciones entre pesos fueron positivas y sólo en S-A fueron negativas entre peso y condición de la madre (P < 0.05).
