--- In the highlands of Perú, commercial chickens show difficulties in how to acclimatize in the hard conditions of the highlands, where there is low oxygen partial pressure, causing less oxygen capture and developing several physiopathological processes which finish in Ascitic Syndrome in Chicken (ASC) and in the most of the cases with the death of the chickens. In the current project is proposed a therapy with Nitrite (NIT), which gives Nitric Oxide (NO) to the organism. NO is a free radical that participate in different physiological process and physiopathological, playing an important role as a vasodilator. In the lungs this vasodilatation helps in the capture of more oxygen, avoiding a heart effort and indirectly the presentation of ASC. It is demonstrated that the enzyme Xantine Oxidase (XO) can produce NO from Nitrite under hypoxic conditions. In the highlands, the administration of NIT had an effect in the presentation of ASC in a proportion control/treated of 2 to 1. In this project 2 experiments were done with chickens of Cob-Vantress line, one experiment was in the coast (Lima), and the other one was in a 3,200 meters high above the sea ( IVITA- MANTARO), in both places were divided in two groups, one with the therapy (NIT 0.1% in water for consume) and other group as a control. The results in the coast show a high concentration of plasmatic NIT in the group with the therapy against the control group, beside any ascitic case was found. The results in the highlands were deciding because in the control group 48 ascitic cases were found from 100 chickens, against 25 ascitic cases from 100 chickens in the group with the therapy, demonstrating that the therapy with NIT played a preventive role in the development of ASC acting as depressor of weight. The reduction of weight in the groups with the therapy was maybe caused for the experimental dose of NIT in the water for consume. The conclusion is that the therapy with NIT in a concentration of 0.1% in water for consume produced, in the highlands, a depressor effect of weight in the treated group and showed a proportion of 2 to 1 in the presentation of ascitic cases in the group control against the group with the therapy respectively. Key Words: NIT= nitrite, NO= Nitric Oxide, XO= Xantine Oxidase, ASC= Ascitic Syndrome in Chickens.
