One hundred and twenty growing pigs and 64 fi nishing pigs were randomlyassigned to 3 densities: 1) = one pig individually allocated with 2.5 m2 of available space; 2) = six growing or four fi nishing pigswith 0.94 and 1.41 m2 of available fl oor space per pig; and, 3) = 12 growing or eight fi nishing pigs with 0.47 and 0.71 m2 of availablefl oor space per pig. The serum concentrations of glucose, urea and cortisol were determined at the beginning of the experimentand at the end of weeks 1, 3 and 5. In growing pigs, ADFC (P < 0.05) and ADG (P < 0.10) were greater for density 1 than fordensities 2 and 3; FE was greater (P < 0.10) for density 2 than for densities 1 and 3. In fi nishing pigs, ADFC and ADG (P < 0.10) weregreater for density 1, than for densities 2 and 3. The glucose, urea and cortisol concentrations were not different among densities.Feed intake and weight gain were reduced as density per pen increased; however, the reduction in performance was not relatedto changes in the serum concentration of some stress indicators such as glucose, urea or cortisol. 2006 artículo científico 0301-5092 https://www.redalyc.org/articulo.oa?id=42337106 en http://www.redalyc.org/revista.oa?id=423 Veterinaria México application/pdf Universidad Nacional Autónoma de México Veterinaria México (México) Num.1 Vol.37 |
