Studies on frozen sperm in are very limited, mostly in Local fowl and quails, however, no study of this sort has ever been conducted in the Green jungle fowl. The common cryoprotectant for frozen ruminant i s glycerol. Procedures using glycerol for poultry sperm resulted in good sperm quality thawing, however, with low fertilizing capacity. For these reasons it i s necessary to investigate the suitable cryoprotectant for freezing poultry semen. From previous experience with frozen Local fowl sperm 6 ethylene glycol or dimethylsulphoxide DMSO could be utilized as for freezing Green Jungle fowl sperm, however, the optimal concentration, effectivity, efficiency and economically, remains to be investigated. The damage, resulted by the freezing as indicated by sperm abnormalities has only been observed by microscopy. More study on the sperm freeze thaw damage should be explored by using the electron microscopy. experiment has been conducted to obtain a method for Green Jungle fowl frozen sperm, by the most cryoprotectant with optimal concentrat ion. The frozen-thawed semen posses high quality suitable for with high motility, morphology, viability and fertilizing capacity. Observation and more detailed study on the of frozen sperm conducted to determine the freeze-thaw damage. The factorial 2x3 completely randomized design was used with 2 factors EG and DMSO and 3 levels of concentration and 8 and 3 times replications. Data were analyzed using the analysis of variance followed by the Duncan multiple range test. Semen was collected and pooled from Green Jungle fowls induced with 40 PMSG .m. Fresh semen quality posses the following characteristics: ejaculate volume v of 0.01 4 0.001 colour, viscous, pH 7.27

and microscopically showed mass movement of 1.0 , concentration 3.036 billions per and 10.47 0.479 abnormality. Frozen-thawed semen motility of the Green Jungle fowl is lowest 8 DMSO 1 and highest in EG Lowest abnormality was found in frozen in 6 EG 8.50 and highest 8 DMSO during 2 hours at was 2.22 from spermatozoa frozen in DMSO and in 4 EG. Frozen-thawed semen decrease motility from 13.89 to 3 with ranging 7.1 8 to 65. The decrease in motility and increase in abnormality of spermatozoa was resulted in semen frozen 8 DMSO and differ significantly either between all concentrations 4, 6 and 8 or EG or DMSO method in the doses determination, the equation for EG i s 46, the equation for DMSO is + - I The axis denotes the post-thaw sperm and the X axis denotes the EG DMSO results show that either EG or DMSO could be used as for Green Jungle fowl. Ethylene glycol EG at concentrations of

4, 6

and 8 could be used safely as DMSO could only be used y at concentration of 4 and 6, while 8 DMSO shows toxic effects to sperm viability Faculty Staff fionr the Department of Physiology and of Reproduction and Faculty of Veterinary Medicine, Agricultural University and of Biology, Faculty of Science and Mathematics, University.
