  "abstract": "<p>The aim of the study was to investigate the effects of feeding programs in combination with supplemental lipotropic<br>agents on performance, ascites-related indices, blood metabolites and breast meat quality in broiler chickens reared at<br>high altitude (2,200 m above sea). A total of 450 day-old Ross broiler chickens were randomly assigned to 6 treatments<br>with 5 pens of 15 birds per each. The experiment was carried out in a completely randomized design with 2 &times; 3 factorial<br>arrangement, including two feeding program (ad libitum or early feed restriction) and three status of lipotropic<br>supplementations (a control diet, 150 mg/kg carnitine as L-carnitine, and 1,000 mg/kg choline as choline chloride). The<br>results showed that dietary supplementation with carnitine improved body weight gain and feed conversion ratio (FCR)<br>in broilers (P&le; 0.05). The relative weight of the heart was lower in broilers fed choline supplemented diet compared with<br>control group (P&le; 0.05). Feeding broiler chickens with carnitine increased the serum concentration of glucose (P&le; 0.05).<br>However, supplementation of the diet with carnitine reduced serum concentration of triglycerides (P&le;0.05).<br>Supplemental carnitine reduced the susceptibility of the meat (thiobarbituric acid number) to lipid peroxidation (P&le;<br>0.05). The ascites-related indices, including the weight of right ventricle (RV) and the ratio of right-to-total ventricular<br>weight were lower in broilers which received carnitine and choline supplementation which reared under early feed<br>restriction (P&le; 0.05). In conclusion, supplemental carnitine improved growth performance, ascites-related indices and<br>meat quality of broilers. Besides, early feed restriction improved ascites-related indices in broiler chickens reared at high<br>altitude.</p>",
