Abstract

50 Pleven Blackhead ewes aged 10-12 months and weighing 40-48 kg were analysed between November and December. Prior to the experiment, all animals from the herd were submitted to transabdominal echographic study with Aloka SSD 500 Micrus equipment and 5 MHz linear transducer and pregnant sheep were ...
