AbstractFull Text

Morphometric data of the reproductive organs and the gonadal and extragonadal sperm reserves were determined in ten sexually mature Balami rams. The mean body weight was 52.5±7.4 kg. The paired testes weight and scrotal circumference were 389.4±4.29 g and 30.3±0.8 cm respectively. The mean weights...
