KUALITAS SEMEN SEGAR DAN RECOVERY RATE (RR) SAPI LIMOUSIN PADA MUSIM YANG BERBEDA
Abstract: This research aimed
to determine the quality of fresh semen and recovery rate (RR) Limousin bulls
at different seasons in Indonesia. The research materials were used semen
sample and recording of 10 Limousin bulls on November 2015 until September
2016. The analyze was used by descriptive, while seasonal factors were
determined by rainfall, they were divided into 2 stage (summer and rainy). The
result was showed that the average of individual motility (60±0.07 %) on summer
and (57.7±0.09 %) on rainy, Consentration of spermatozoa (1043±208 million/ml)
on summer and (1013±175 million/ml) on rainy, post thawing motility (44±0.02 %)
on summer and (41±0.05 %) on rainy, RR value (65±0.05 %) on summer and (55±0.09
%) on rainy, the production of frozen semen (1979±644.2 straw) on summer and
(1623±379 straw) on rainy. It was concluded that the best quality of fresh
until frozen semen was generally on summer with low rainfall. The seasonal
effect for quality of semen Limousin bulls were individual motility, concentration,
PTM, and RR value will be impacted for frozen semen produce. It was advisable
to rejected the Limousin bulls with poor semen quality.
