摘要: 1. There are few studies on the effect of dietary protein content pulmonary hypertension syndrome (PHS) in broiler chickens. Conflicting results from these prevent a clear conclusion effects reduced-protein diets development syndrome. 2. To obtain an understanding mechanisms involved, current study, conducted at high altitude (2100 m above sea level), evaluated three treatments that varied only according to (CP) levels. One treatment with CP advocated by National Research Council (1994) acted as control. Two were also prepared reduced 20 and 40 g/kg relative control, which designated LCPD2 LCPD4, respectively. A total 180 d-old male broilers (Ross 308) randomised across 15 floor pens measuring 1.5 m2 (12 birds per pen). Five such (replicates) allotted each treatment. The applied 1 42 d age gro...
