dietary<br> L-carnitine on electrocardiographic pathern of broilers reared at high altitude (2100 m). A number of 192 day-old chicks (Cobb 500) were selected from a group of 300 chicks and assigned to four treatments with four replicates of 12 birds. All chicks were raised on floor pen up to 42 days of age. Treatments composed of four levels of dietary<br> L-carnitine<font size="3"><font face="Times New Roman"><span style="mso-spacerun: yes">&nbsp; </span>(0, 50, 100, and 150 mg/kg). The control diet was formulated to meet the NRC (1994) nutrients recommendations. Results indicated that in Lead II,the amplitude of S-wave was significantly reduced (P<0.05) in broilers fed 50 mg/kg L-carnitine compared to the control. Such reduction in S-wave was also observed in Leads III and aVF. Amplituds of R-wave in Lead II and T-waves in all Leads did not show any significant difference among treatments. The right ventricular weight ratio tended to reduce in birds fed L-carnitine supplemented diets so that the difference between the control and 50 mg/kg L-carnitine treatment was significant (P<0.05). The results of this study showed that supplementary L-carnitine had beneficial effect on electrocardiographic response, as manifested in reduced S-wave amplitude and heart function </font></font><a name="_GoBack">in </a>broiler chickens.</span> جوجه گوشتی, امواج الکتروکاردیوگرام, فشارخون ریوی, کارنیتین Chicken, Electrocardiography, L-carnitine, Pulmonary Hypertension 1 12 http://rap.sanru.ac.ir/browse.php?a_code=A-10-1-78&slc_lang=fa&sid=1 Fariborz Khajali فریبرز خواجعلی 100319475328460010201 100319475328460010201 Yes Share Kord University دانشگاه شهرکرد Azam Yousefii اعظم یوسفی 100319475328460010202 100319475328460010202 No Share Kord University دانشگاه شهرکرد Hosseyn Hassanpour حسین حسن پور 100319475328460010203 100319475328460010203 No Share Kord University دانشگاه شهرکرد
