Pengaruh pengencer komersial terhadap motilitas dan viabilitas spermatozoa semen babi landrace yang disimpan pada temperatur berbeda

The objective of this study was to determine the the effect diluent of commercial is diluent BTS® and MIII® in maintaining sperm motility and viability of landrace boars during storage at different temperatures at refrigerator (5 °C), AC (28 °C) and room temperature (32 °C). This experiment used a completely randomized design (CRD) with 6 treatment and 4 replications. Semen was collected twice a week from landrace boars. Semen Characteristic and their quality were evaluated macroscopically and microscopically. Good quality semen have motility >70%, sperm concentration 200 x 106 sperm/ml and morphological abnormality less than 20%, these semen were added with diluent commercial is diluent BTS® and MIII®. Sperm motility and viability were evaluated every 2 hours until 40% motility were evaluated. The result showed that fresh semen characteristic were good, with the presentage of sperm motility 85% with sperm concentration 242.50±16.5% and morphological abnormality 12.50±1.70%. The results showed that the liquid semen of landrace boar were stored at a temperature of 28 °C is better results temperature with the percentage motility of sperm 54.50% during 38 hours and temperature of 5 °C showed the second best result with the percentage of 46.32% motility during 36 hours of storage in the diluent BTS® . In conclusion : BTS® diluent is an appropriate diluent used to maintaining semen quality of landrace boars quality during preservasion
