The purpose of this research was to evaluate the viability of ram epididymal sperm collected from fresh caudal epididymis (H-0) or after storage in low temperature (5oC, in refrigerator) for one (H-1), two (H-2), and three (H-3) days. Collected sperm were diluted in modified Tris extender and they were preserved in refrigerator up to four days. The viability of diluted sperm was evaluated daily base on motility and sperm live. Results indicated that mean sperm concentration after sperm diluted with 0.05 ml Tris extender of caudal epididymis was 2745 million/ml. Sperm motility and percentage of live for H-0 (71.25% and 82.83%) and H-1 (70.00% and 79.17%) were significantly higher (P<0.05) than H-2 (61.25% and 69.83%) and H-3 (51.67% and 66.17%). Percentages of sperm motility and live of diluted sperm and preserved in refrigerator for H-0 were significantly higher (P<0.05) than H-1, H-2, and H-3. These results showed that epididymal sperm collected from caudal epididymis up to three days of preservation (without further storage of the diluted sperm) could be used for artificial insemination or in vitro fertilization programs. Diluted sperm of H-0 and H-1 could be preserved in refrigerator for two days and H-2 for one day.

The aim of this research are to know the effects of physiological NaCl dilution levels and storage duration on sperm motility and abnormality of Muscovy duck. Materials which used in this research were semen that collected of 1 - 1,5 years of four Muscovy duck. Semen were treated by physiological NaCl dilution levels nol , three, six and nine and storage duration ( t0 = 0 minute t1 =45minutes and t2=90 minute). Replication was three tapping periode . The method of this research was laboratory experimental with Randomized Complete Blok Design (RBD) in Split Plot Design (SPD) pattern ,as main plot is Physiological NaCl dilation levels and as sub plot is storage duration. Result of the experiment showed that physiological NaCl dilution levels was very significantly influences on sperm motility (p<0,01) and significantly influences and sperm abnormality (p<0,05) . The storage duration was very significantly influences and sperm motility and abnormality (p<0,01) .Orthogonal duration polynomial assayed showed that the effect of physiological NaCl dilution levels to sperm motility had a linier regression line with the a equation as Y =69.94 - 2.65 X,  r=0,49 R2=0.24 with Y presented to sperm motility and X represented to physiological NaCl dilution levels sperm and effect of storage duration to sperm motility had a linier regression line with the equation as Y =74.24-0.35 X, r =0.73 R2=0.53 with Y represented to sperm motility and X represented to storage duration . The effect of physiological NaCl dilution levels to sperm abnormality had a linier regression line with the equation as Y =5.61+0.34X, r=0.52 R2=0.27 with Y represented to sperm to abnormality and X represented to regression line with the equation as Y =6.74+0.01X, r=0.24R2=0.060 with Y represented to sperm abnormality and X represented to storage duration. It is can be concluded that a higher physiological NaCl dilation levels and storage duration caused sperm to motility decreased and sperm abnormality increased.

AI for cattle has been develop in Indonesia in contrast, AI for small ruminants (sheep and goat) are less developed. Its due to the lack of facilities, processing and packaging during storage. This research aims to compare the effectivity and efficiency of two different packaging technique (test tube and straw). Test tube and 0.25 ml mini straw were tested . Semen was obtained from adult PE buck (3 yr) after collection by using artificial vagina. The fresh semen was then evaluated and diluted 5 folds with 2.9 percent Na-citrate. Diluted semen then packed in test tube and mini straw, and stored in refrigerator (100C) for 7 days. Observations were done everyday on sperm motility, abnormality and percentage of live sperm. Observation were made at 370C. Observation on fresh ejaculate showed that semen has 6x 109/ml concentration, 90 percent motility, 8 percent abnormality and 95 percent live sperm. Five folds dilution reduced sperm concentration to 1.2 x 109/ml, but did not change sperm motility, abnormality and percent of live sperm. Sperm was then packed according to the treatments. Storage in both packaging did significantly reduce (P<0.01) sperm motility and percent live sperm, but not for sperm abnormality. All sperm stored in test tube were classified death at day 5 storage. However, sperm in the straw were remain live eventhough the percentages was low. It can be concluded that straw has a better result than test tube. Eventhough sperm motility was extremely low, it remains valuable for cervical insemination. (Animal Production 1(1) : 24-29 (1999).  Key Words : Sperm, PE Buck, Straw, Test Tube

The research entitled “The Effect of Level Testosterone Addition in Diluents and Level Dilution on Speed Movement and Abnormality of Kedu Chicken Sperm†was conducted in Laboratory of Physiology and Reproduction, Faculty of Animal Science, UNSOED, started at August 15th to September 15th , 2001. The aims of this research were to obtain influences of level testosterone and dilution on speed movement and secondary abnormality kedu chicken sperm and obtain interaction between the treatments. The tapped sperm from nine kedu chickens were used in this research. This Experiment was performed 4 x 3 Factorials with Randomized Completely Block Design (RCBD) as the basic design. The treatment combinations were level testosterone 0, 300, 600 and 900 μg (t0, t1, t2 and t3) and level of dilution 4, 6 and 8 time (in a row p1, p2 and p3). The tapping period was replicated four times as a group (replicated) with two days interval. The result of this research showed that the interaction between level of testosterone addition and level of dilution gave a non-significant effect to speed movement sperm but significant to abnormality of kedu chicken sperm. The group gave a significant influence (P<0.05) to speed movement sperm and non significant to sperm abnormality. The interaction of level testosterone addition and level dilution of kedu chicken semen (T x P) has a quadratic regression to sperm abnormality with regression comparison is Y = 24.418 – 0.014 X +1.187E – 05 X², with peak point is (543.76: 20.23) of correlation coefficient (r) 0.55 and determination coefficient (R²) as 30.34%. The addition of 600 μg testosterone level with 6 level dilutions was the best to defend sperm abnormality.
