Edad y peso objetivo al criar vaquillas para productos lácteos
La cría de vaquillas es una de las áreas más costosas de la granja. Desde el día en que estos animales tocan el suelo hasta que paren, son una carga monetaria para la granja. Por lo tanto, hacer que estos animales parieran de la manera más eficiente posible tiene sentido.

¿Seguimos necesitando la regla A. M. / P. M.?
Durante más de medio siglo, se ha adoctrinado a los productores de leche en el uso de la regla A. M. / P. M. para la inseminación artificial (IA) del ganado lechero. En esencia, la regla A. M. / P. M. dicta que una vaca debe ser inseminada artificialmente 12 horas después de haber sido observada en estro (celo). Si una vaca se ve en celo en la mañana, debe ser inseminada artificialmente en la tarde y, a la inversa: las vacas en estro en la tarde deben ser inseminadas artificialmente a la mañana siguiente.
