The population of anoa, which is an endemic fauna to Indonesia, was getting decrease caused by the illegal hunting and deforestation. Anoa is included in endangered species by IUCN, and Appendix I by CITES. The experiment aimed to characterize the seminal plasma contents and to cryopreserve the anoa semen for artificial insemination application in captivity. The experiment was carried out in Taman Safari Indonesia (Bogor). Semen was collected from 2 anesthetized males (4-10 years) by electroejaculation. Seminal plasma gained by centrifugation of ejaculate (3000 rpm, 20 minutes), and then was evaluated the biochemical contents. Other ejaculates were evaluated macroscopically and microscopically, and then extended in Tris and Na-citrate media to a total concentration of 100 billion cells mL-1. Extended semen was stored at 4oC, and evaluated the motility and viability every 12 h. Frozen semen was made in Tris medium added with 5% of glycerol. The seminal plasma of anoa contained total lipid, Na, Ca and Mg higher than the buffalo, but its total protein, K and Cl were lower. Electrophoresis of seminal plasma using by SDS-PAGE method showed 10 bands of proteins (17-148 kDa). The motility and viability of chilled-extended semen in Tris and Na-citrate media were not significantly different (P > 0.05) during 72 h of evaluation. Extended semen in both of media may applicable for AI program for 24-48 h. Post thawing motility of frozen semen was still low, 26.00 ± 9.62%. Therefore, it is necessary to improve each stages of semen processing, so the motility will increased and resulted high pregnancy in AI program.

Pregnancy-associated glycoprotein (PAG) structurally related to aspartic protease, expressed in the outer epithelial cell layer (trophectoderm) of ungulate placenta. Ovine PAG (ovPAG) synthesized by mono- and binucleic trophoblast before complete implantation at Day 14-15. Of this, ovPAG could be used as a marker for early pregnancy. The objective of study was to extract and isolate PAG from placenta of Garut Sheep collected at term and to characterize their molecular weight. The procedures included extraction of protein at neutral pH (cotyledon was thawed, minced, added PBS, blended and centrifuged), acidic (H3PO41M, pH 4,5; centrifuged) and ammonium sulfate (40% and 80% (NH4)SO4, centrifuged) precipitation; gel filtration (Sephadex-G75), anion exchange chromatography (DEAE- cellulose). Cotyledon extract was subjected to Sephadex-G75 and DEAE cellulose, and their fractions were measured their absorbances. Absorbances of Sephadex-G75 and DEAE fractions at peak were assayed for protein concentration (Bichinconinic protein assay). Continuously, these fractions were subjected to monogel SDS-PAGE and stained by Commassie Brilliant Blue. It was four different molecular weights isolating from cotyledon of Garut Sheep, namely 68.8, 36.04, 32.39 and 12.18 kDa. However, after chromatography anion exchange (DEAE-cellulose), only three bands exist, those were 71,67; 33,64 and 30,86 kDa. Key words: Garut sheep, Pregnancy-Associated Glycoprotein (PAG), Cotyledone, SDS-PAGE, DEAE-cellulose

Different subtypes of bovine herpesvirus 1 (BHV-1) have been associated with different clinical conditions of cattle. For that reason subtypes differentiation has become an essential tool for understanding the pathogenesis and epidemiology of BHV infections. In search for a genomic region that would allow a clear distinction between BHV-1.1 and BHV-1.2 of glycoprotein D (gD) genes of 8 Indonesian isolates were amplified and sequenced. The amino acid sequence alignments revealed that the levels of genomic similarity ranging from 98.8 to 100% among BHV-1 Indonesian isolates and its results were also similar between BHV-1 Indonesia isolates and BHV-1.1 reference, and 98.4 to 98.8% between BHV-1 Indonesian isolates and BHV-1.2 reference. The isolates could be clearly separated into BHV-1.1 and BHV-1.2 after phylogenetic analysis. The results showed that the Indonesian isolates were characterized as BHV-1.1 as agent caused respiratory tract infections in cattle or infectious bovine rhinotracheitis (IBR) disease. The results suggest that the phylogenetic analysis performed here can be used as a potential molecular epidemiological tool for herpesviruses.
