In this study, we investigated the effects of ethanol on different parameters in broilers. A-day- old broiler chicks (n = 90) were randomly divided into five groups from A to E (negative control) at 22 days of age. Ethanol (2, 4 and 6 ml) and tap water (6ml) were administered into the crop from 22 to 42 days of age daily.  Administration of ethanol through a crop tube at experimental dose levels showed a better feed conversion ratio, while lower live body weight in all treatment groups in almost a dose-related manner. Results of different organs also revealed significant decrease in the relative weight of most of the organs including heart, proventriculus, kidneys, intestine, brain and pancreas. Similar were the effects on ventricular volume (left and right). The relative weight of the intestine decreased significantly at 28 days of age, while increased significantly at 35 and 42 days of age. There was a significant decrease in diameter of duodenum, jejunum and ileum. The results of the present study showed less effect on gizzard weight, especially at 42 days. While the relative weight of liver and lungs were not affected. We were unable to find consistent significant gross and microscopic pathological changes in organs/tissues under study. The study revealed that ethanol at these dose levels through crop route has effects on live weight and relative weights of most body organs/tissues.
