The present study was conducted to investigate the variations in blood serum and hepatic levels of vitamin A and b-carotene in Ghezel sheep throughout the year. From 1000 sheep aged 1-5 years, blood and liver samples were collected before and after slaughter. The levels of vitamin A and \beta-carotene in both samples were determined spectrophotometrically. The results showed significant differences between summer and winter values (P < 0.05), but no differences were found between the sexes (P > 0.05). There were significant correlations between the vitamin A levels in serum and the liver (P < 0.05). Due to low levels of vitamin A and \beta -carotene in Ghezel sheep during the winter, supplementary feeding of vitamin A is recommended during this season.

The purpose of this study was to obtain detailed information about the normal size and texture of the goat liver by means of ultrasonographic examination. The structure, location, and size of the liver, portal vein, and caudal vena cava were examined ultrasonographically in 6 goats. The angle of the liver and the thickness of the gallbladder wall were also determined. Examinations were performed on the right side of the abdomen, from the 6th through 12th intercostal space, using a 6-13 MHz linear transducer. In each intercostal space the dimensions of the liver, and if visible, the location and diameter of …
