ANTECEDENTES
v En condiciones de estrés calórico, las vacas Criollas
Limoneras de pelo corto tuvieron menos (P<0.01)
respiraciones por minuto que las de pelo normal
(56 + 3 vs 69 + 4).
v Una diferencia de 13 respiraciones más por minuto,
representa 18720 respiraciones más por día. Ello
implica que por concepto de termorregulación hay un
elevado gasto de energía.
v Cuántos kilos de leche y carne se dejan de producir por
este concepto ????.
