Abstract

The success of freezing chicken semen is the hope for preserving Indonesian native chickens. Semen from twenty Arab roosters were collected using massage technique once in a week. Cryoprotectant DMA (dimethyl acetamide) or DMF (dimethyl formalmide) of 7 or 9% and thawing A at temperature of 30oC for 30 seconds or in B at 5oC for 5 minutes. The volume of fresh semen was 0.3 ± 0.072 ml/ejaculate, white colour, rather thick to thick, with 2200 ± 372 millions sperms/ml and pH 6.95 ± 0.32, 4+/3+ mass movement, 80% motility, 84 ± 4.48% and abnormality of 14.75 ± 1.28%. There were not statistically significant (P>0.05) effect of interaction of treatments (kinds and concentrations of cryoprotectant, and thawing methods) on motility and live-sperms. Sperm motility preserved with DMA (34.69%) significantly higher than with DMF (29.84%). Sperm motility was also significantly higher (34.53%) when preserved with 7% cryoprotectant than with 9% (30%). Thawing-A significantly gave higher motility (35.31%) than thawing-B did (29.22%). Live-sperms of semen preserved with DMA (46.75%) was significantly higher than with DMF (41.72%). Cryoprotectant concentration of 7% gave higher live-sperms (46.98%) than of 9% did (41.48%). Thawing-A left live-sperms of 47.14%, which was significantly higher than thawing-B did (41.30%).
