<![CDATA[The study aims to determine the effect of commercial thinning is thinning Beltsville thawing Solution (BTS) and Mulberry III (MIII) with a water jacket method and non-water jacket against landrace pig semen quality after stored at 5° C. This study uses a completely randomized design (CRD) with 4 treatments and 2 control within five repetitions. Fresh semen that fulfill the criteria diluted with Beltsville thawing Solution (BTS) and Mulberry III (MIII), then stored using non-water jacket and water jacket at 5 °C of temperature. Motility and viability observations of spermatozoa performed every 2 hours after storage for up to a decline in the percentage motility of at least 40%. Research result shows the characteristics of fresh semen motility is 84.50 ± 0:50, the concentration is 250 ± 8:36 sperm cells / ml and 13.60 ± 1.72 abnormality. Semen observations which diluted with Beltsville thawing Solution (BTS) at 5 °C temperature shows the water jacket method is better than the non-water jacket method with a percentage of 57.00 ± 1.22 % motility during 32 hours storages. Semen observations which diluted with Mulberry III (MIII) at 5 °C temperature shows the water jacket method is better than the non-water jacket method with a percentage of 51.00 ± 1.00% motility during 32 hours storages. Semen observations which diluted with Beltsville thawing Solution (BTS) and Mulberry III (MIII) shows the BTS water jacket liquid semen is better than BTS non water jacket, miii water jacket and miii non water jacket with motility percentage 57.00 ± 1.22% for 32 hours storages. It was concluded that the water jacket method is better than the non-water jacket method and water jacket BTS is more effective to maintaining the spermatozoa quality during storages at 5 ° C.]]>
