Cabras criollas: inicio reproductivo y productividad en la zona de La Plata
The influence of age and weight of creole goats in their first and second parturition productivity was studied. Weight at birth, age, weight and month of their first service, prolificity, pre and post-partum weight, breeding weight and milk production were determined in both parturitions. Goats were grouped according their age at first parturition: L1, less than 12 months; L2, more than 12 months. L1 females were heavier at birth than L2. Birht weight and prolificity showed significant higher values in L2 female. Other variables had no diference among groups. Services distribution were significant different between first and second pregnancy. There were no spring season service for little goats. Early services in little goats had no effect on their productivity. We suggest to use little goats born in spring with higher weight, next autumn.

El objetivo del presente trabajo fue evaluar la incidencia de la edad y peso al primer servicio de cabrillas criollas de reposición sobre la productividad al primero y al segundo parto. Se registró: peso al nacimiento de las cabrillas, edad, peso y época del primer servicio, peso preparto, postparto, peso vivo parido, relación porcentual entre el peso de las crías al nacimiento y el peso postparto de la madre, prolificidad, peso de las crías y producción de leche a los 30 días, e intervalo entre partos. Las cabrillas que tomaron servicio antes del año de vida (L1) resultaron significativamente más pesadas al nacimiento. El peso al primer servicio y la prolificidad de las hembras que tomaron servicio con una edad superior al año de vida (L2) fueron significativamente superiores. Las épocas de servicio variaron de la primera a la segunda preñez, no registrándose servicios primaverales en cabrillas de primera parición. Para el nivel productivo de la cabra criolla, una utilización precoz de las hembras de reposición no afectaría la productividad al segundo parto. Resulta recomendable utilizar los animales nacidos en primavera con mayor peso para su inicio reproductivo en el otoño siguiente.
