We examined the effects of oral administration of L-citrulline (L-Cit) on plasma metabolic hormones and biochemical profile in broilers. Food intake, water intake, and body temperature were also analyzed. After dual oral administration (20 mmol/head/administration) of L-Cit, broilers were exposed to a high ambient temperature (HT; 30 ± 1°C) chamber for 120 min. Oral administration of L-Cit reduced (p <.001) rectal temperature in broilers. Food intake was increased (p <.05) by heat stress, but it was reduced (p <.05) by L-Cit. Plasma levels of 3,5,3′-triiodothyronine, which initially increased (p <.0001) due to heat stress, were reduced (p <.01) by oral administration of L-Cit. Plasma insulin levels were increased by heat exposure (p <.01) and oral L-Cit (p <.05). Heat stress caused a decline (p <.05) in plasma thyroxine. Plasma lactic acid (p <.05) and non-esterified fatty acids (p <.01) were increased in L-Cit-treated heat-exposed broilers. In conclusion, our results suggest that oral L-Cit can modulate plasma concentrations of major metabolic hormones and reduces food intake in broilers.
