A study on the influence of gastrointestinal trichostrongyles on ram fertility was performed. Two groups of semen donor rams (Sarda breed) were utilized; one was experimentally infected with Haemonchus contortus, Trichostrongylus colubriformis and Teladorsagia circumcincta and the other was used as a control group. In all animals, coprological, haematological and reproductive parameters were st...

The successful application of assisted reproductive techniques (ARTs) in ovine as other mammal species relies on many factors among which the quality semen used. After collection, samples are generally processed for storage (liquid or cryoconservation) before being used insemination vitro embryo production. During liquid process, sperm cells exposed to artificial conditions lead oxidative stres...

Aim of this study was to select superior rams by assessing their scrotal size and quality semen. In ten indigenous Bangladeshi rams, the body weight, circumference, volume increased with age (P<0.05). Body weight at 381-410 days (13.6 ± 1.5 kg) higher than 169-200 (10.2 0.1 201-230 (10.4 1.2 (p<0.05). Scrotal circumference 381 - 410 (19.1 0.3 cm) (p<0.05) 169 200 (17.2 cm), 201 230 0.6...
