Pengaruh Level Minyak Kelapa Murni dalam Pengencer Air Kelapa Muda Terhadap Kualitas Spermatozoa Babi Landrace

This study aimed to examine the addition of various levels of virgin coconut oil (VCO) in young coconut water-egg yolk (YCW-EY) diluent on the quality of landrace boar spermatozoa. Semen was collected once a week using the massage method from landrace boars that have reached sexual maturity with healthy conditions. This study was experimental with a completely randomized design consisting of five treatments and five replicates. The treatments consisted of young coconut water (YCW 80%) and egg yolk (EY 20%) added with virgin coconut oil (VCO) with levels: 0% (P0), 2% (P1), 4% (P2), 6% (P3) and 8% (P4). The diluted semen was stored in a cool box at 15-20ºC and evaluated every 8 hours for motility, viability, abnormality and survival of spermatozoa up to a minimum motility of 40%. The results of this study showed that semen diluted using YCW-EY in treatment P4 (VCO 8%) had higher quality (P<0.05) compared to other treatments, namely motility reached (43.00±7.59%), viability (49.20±7.59%), abnormality (4.56±2.36%) and survival (25.42±2.78 hours). It was concluded that the addition of 8% VCO to YCW-EY diluent was effective in maintaining the quality of landrace boar spermatozoa.
