Methods adopted from domestic bull protocols Banteng sperm maintains motility in both egg-yolk and whole milk based extenders for 24 h at 5°C Sperm frozen in an egg-yolk Tris diluent (Biladyl) with 5-7% glycerol provided the highest post-thaw motility of 43% compared to TEST and whole milk diluents at 26% and 29%, respectively

The cervix in banteng is more caudal than in domestic cattle. A plastic pliable catheter is used for semen deposition, to mitigate the risk of trauma in a restrained, non- anesthetized animal. Defining Success

Objectives
Objective 1. Effects of oxytocin on semen volume and sperm concentration. Objective 2. Comparison of varying extenders and temperature on short- term sperm storage. Objective 3. Effects of cryoprotectant concentrations and cholesterol- loaded cyclodextrins on sperm motility and on sperm cryopreservation. Objective 4. Fertilization rates of cholesterol-loaded cyclodextrin treated frozen-thawed sperm using heterologous in-vitro fertilization. Objective 5. Characterization of lowland anoa estrous cycle through non- invasive fecal hormone and behavioral monitoring. Objective 6. Effects of exogenous prostaglandins on lowland anoa corpus luteum and efficacy in manipulation of the estrous cycle for artificial insemination.
