Abstract
El consumo de alimentos sólidos (forrajes o pienso) durante la lactación es vital para
alcanzar una correcta transición de pre-rumiante a rumiante adulto (Coverdale et al., 2004).
La naturaleza de estos alimentos juega un papel importante en el desarrollo del rumen,
provocando una mejor adaptación del animal a la posterior dieta de cebo, con altos niveles
de carbohidratos rápidamente fermentables, y ayudando a prevenir la posterior aparición de
problemas de acidosis (Khan et al., 2011). El objetivo de este experimento fue determinar el
manejo nutricional más adecuado durante la lactación para conseguir una buena adaptación
al posterior periodo de cebo en ganado vacuno de carne.
Thirty calves of two breeds (Parda de Montaña and Pirenaica) were used to assess !he most suitable feeding strategy (milk only, milk + grass hay or milk + concentrate) during lactation to achieve an adequate adaptation of beef calves to the fattening period, when a high-concentrate die! is offered. Rumen fermentation parameters were affected by supplementation, resulting in a more developed rumen when concentrate was offered. Glucosa and P-hidroxybutyrate concentrations in plasma were not influenced by die! bu! showed a shift in metabolic pathways and fue! used by !he animal, except far animals supplemented with grass hay. Supplementing with concentrates during lactation seems a recommendable practica sinca it improvas ruman farmantation with a carry-ovar effact during transition when cattle will be fed a high-concentrate diet.
