Fig. 8From: Effects of arginine replacement with L-citrulline on the arginine/nitric oxide metabolism in chickens: An animal model without urea cycleGene expression of tight junction proteins in the intestine of broilers fed arginine deficient diets supplemented with arginine or L-citrulline. (A) Ileal mucosa (B) Jejunum tissue. PC: Positive control; NC: Negative control; NCL: Negative control + L-citrulline. Data are presented as mean ± SEM (n = 8). Data are significantly different at *P < 0.05; ***P < 0.001Back to article page
