RESUMO

Objective: To explore the effect of glycerol at different concentrations using different extenders on DNA fragmentation and motility of frozen-thawed Kintamani Bali dog spermatozoa. Materials and Methods: Sample was collected from four mature Kintamani Bali dogs. Each ejaculate was prepared for cryopreservation with two different semen extenders; egg yolk Tris extender and coconut water-based extender. For each extender, three different glycerol concentrations were used; 4%, 6%, and 8%. Each of the six aliquots was loaded into 0.5 ml cryotube, placed on a styrofoam box 5 cm over liquid nitrogen for 10 min, and immersed in liquid nitrogen up to 8 min. Then, the frozen cryotubes were transferred into liquid nitrogen container. The cryotubes were thawed in a water bath at 38.5°C for 120 sec. After equilibration and thawing, each sample was assessed for motility parameters and for DNA fragmentation. Results: The addition of 6% glycerol to extenders revealed the most effective addition of glycerol on motility and sperm DNA fragmentation after equilibrium and post-thawing. Conclusion: It is concluded that both extenders with the addition of 6% glycerol are safe to be used as an extender in Kintamani Bali dog semen preservation, and DNA fragmentation of Kintamani Bali dog spermatozoa was not influenced by the freezing procedure.

RESUMO

Many working equids in developing countries experience poor health and welfare due to environmental and management factors. Collecting baseline data on these populations is essential to inform education projects to improve equid health and welfare. Gili Trawangan is an island in Indonesia that has no motor vehicles and a working pony population of approximately 200. This pilot study sought to determine baseline data on their health, welfare, and husbandry to inform future health and welfare strategies. A cross-sectional study was performed in May 2017 consisting of a pony cart driver questionnaire (n = 33) and a basic pony health examination (n = 38). The body condition scores of ponies were 3/5 (60.5%), 2/5 (31.6%), and 1/5 (7.9%), while 38% and 92% of ponies had lameness and foot pathology, respectively, and 31 ponies (86.1%) had at least one wound. Thirty percent of cart drivers stated they would work their ponies despite evidence of injury or illness. Limited education, poor access to veterinary services, and remoteness pose barriers to improving pony health and welfare. Our results indicate a need for, and can help inform, targeted education programmes to improve the lives of working ponies and protect livelihoods and tourism on Gili Trawangan.
