The study was conducted to evaluate the effect of cryoprotectant and equilibration period on quality and fertility of duck and muscovy spermatozoa. Semen collected from Alabio and muscovy drakes was diluted using three different cryoprotectants:glycerol, DMSO and DMF, thereafter the semen was equilibrated 50C for 15; 30 and 60 minutes then frozen and stored in liquid nitrogen, designed by factorial 3 x 3. After thawing, semen sample was investigated on the motility and mortality rate. The best cryoprotectant and equilibration period was used in fertilization test. Duration of fertility was calculated from the second day after insemination until the last fertile egg, and the percent of fertility was calculated from the second day until the forth day after insemination. The use of cryoprotectant significantly affected sperm motility after freezing. The use of glycerol as a cryoprotectant was the lowest (P<0.05) compared to DMSO and DMF. Similarly, duck sperm motility after being freezed with glycerol, DMF and DMSO were 9.02; 21.75, and 32.86%, and for muscovy sperm motility were 11.78; 32.45 and 34.92% respectively. The percentage of live sperm for duck were 23.84; 40.14 and 42.20, while for muscovy were 29.26; 53.06 and 51.80 respectively after being freezed with glycerol, DMF and DMSO. Equilibration period did not affect the percentage of live sperm after freezing. Results of this study showed that duration of fertility of Alabio duck after being inseminated with fresh drake semen was longest compared to that of insemination using fresh muscovy semen, frozen drake semen and frozen muscovy semen (4.96 vs 3.5; 2.4 and 1.5 days respectively). Results from this study clearly indicated that preservation of sperm reduced the quality of spermatozoa. It is suggested that freezing technique of both duck and Muscovy sperm could be conducted using DMF or DMSO as a cryoprotectant with the equilibration period between 15 to 60 minutes.

This study was conducted at Laboratory Reproduction of Physiology, Research Institute of Animal Production. The experiment was factorial design with two kinds of cryoprotectant (DMF and DMA) as the first factor and two levels of them (7 and 9%) as the second factor. This study was invented to determine the effect of cryoprotectant and its level to survivability of drake semen. Sperm was collected from fifteen drakes two times per week using artivicial vagina. Only the best quality of sperm was used in this study. Collected sperm was diluted in medium to get concentration of 400 x 106 per ml. Equilibrated at 50C in mini straw (0.25 ml) for 60 minutes, then kept them up 8 cm above the LN2 for 4 minutes before plunged in LN2. Parameters measured of this study were survability of drake semen after diluted, at 50C and after freezing-thawing at 350C for 30 seconds. Result of this study showed that percentage of motility and percentage of live sperm were significant different (P<0.05) between DMA (33.24 and 42.03) and DMF (25.82 and 34.30). Level of cryoprotectant (7 and 9%) were not significant different. Based on this study, using DMA as cryoprotectan with 7% in medium was better than that of DMF. Â Key words: Cryoprotectan, survivability, drake sperm

A study on morphological body conformation of Alabio, Bali, Khaki Campbell, Mojosari and Pegagan ducks was carried out to determine the genetic distance and discriminant variables. This research was held in Research Institute for Animal Production, Ciawi, Bogor using 65 Alabio ducks, 40 Bali ducks, 36 Khaki Campbell ducks, 60 Mojosari ducks and 30 Pegagan ducks. Seven different body parts were measured, they were the length of femur, tibia, tarsometatarsus, the circumference of tarsometatarsus, the length of third digits, wing and maxilla. General Linear Models and simple discriminant analysis were used in this observation (SAS package program). Male and female Pegagan ducks had morphological size bigger than Alabio, Bali, Khaki Campbell and Mojosari ducks. Khaki Campbell ducks were mixed with Bali ducks (47.22%) and Pegagan ducks from isolated location in South Sumatera were lightly mixed with Alabio and Bali. Mahalanobis genetic distance showed that Bali and Khaki Campbell ducks, also, Alabio and Mojosari ducks had similarity, with genetic distance of 1.420 and 1.548, respectively. Results from canonical analysis showed that the most discriminant variables were obtained from the length of femur, tibia and third digits. Â Key words: Duck, genetic distance, morphological
