Manejo del ternero y productividad en vacas nodrizas

Abstract

El efecto negativo de la crianza sobre la función reproductiva depende de la frecuencia, intensidad y duración del amamantamiento. La nutrición prepar- to y el tipo de manejo del ternero determinan el anestro posparto, que puede oscilar entre 45 y 90 días. Los mayores ritmos de crecimiento de terneros y menores ganancias de peso de las vacas se observan en régimen de dos periodos de amamantamiento al día (2×30 min) y en crianza libre, mientras que las menores ganancias diarias de los terneros y mayores ganancias de las vacas se registran con un periodo de amamantamiento al día por la mañana (1×30 min). Cuando los partos tienen lugar después de un periodo de subnutrición alimentaria, sería necesario restringir el acceso del ternero durante la crianza para no comprometer los resultados productivos y repro- ductivos de la vaca nodriza.
