Abstract

Penelitian ini bertujuan mengetahui peningkatan level steroid dan persentase kebuntingan sapi aceh terhadap induksi ovulasi dengan metode presynch-ovsynch. Dalam penelitian ini digunakan sepuluh ekor sapi aceh betina dengan status tidak bunting, minimal dua bulan pascapartus, sudah pernah beranak, dan sehat secara klinis. Sapi dibagi atas dua kelompok, yang masing-masing terdiri atas lima ekor sapi. Kelompok pertama (K1) disinkronisasi berahi dengan metode presynch-ovsynch. Pada kelompok kedua (K2), disinkronisasi berahi menggunakan 5 ml PGF2 secara intramuskulus dengan pola penyuntikan ganda dengan interval 12 hari. Setelah 48 jam akhir perlakuan, sapi pada K1 dan K2 diinseminasi menggunakan semen beku fertil. Observasi berahi dilakukan setelah penyuntikan terakhir. Koleksi darah untuk pemeriksaan level estradiol dilakukan segera setelah inseminasi dilakukan sedangkan koleksi darah untuk pemeriksaan progesteron dilakukan pada hari ke-7 pasca-inseminasi. Level steroid diukur menggunakan teknik enzyme-linked immunosorbent assay (ELISA). Pemeriksaan kebuntingan dilakukan 90 hari pasca-inseminasi menggunakan teknik palpasi rektal. Seluruh sapi menunjukkan gejala berahi setelah perlakuan. Level estradiol dan progesteron pada K1 vs K2 masing-masing adalah 294,98110,48 vs 392,7611,6 pg/ml (P0,05) dan 23,8515,14vs 12,695,64ng/ml (P0,05). Persentase kebuntingan pada K1 vs K2 masing-masing adalah 60,0 vs 0,0%. Dari hasil penelitian disimpulkan bahwa metode presynch-ovsynch tidak dapat meningkatkan level steroid tetapi dapat meningkatkan persentase kebuntingan pada sapi aceh.

Abstract

This study has long-term objectives to obtain immunogenic prototype that can be used to induce multiple ovulation in goats. Working steps of this study were begun with the collection of ovarium from goats, collection of granulose cells, culture of granulose and characterization of molecular weight and isoelectric point (pI) of inhibin protein of granulose cells obtained from culture and non-culture of granulose cells, and followed by preparation of monoclonal antibody toward inhibin. The results showed that inhibin isolated either from culture or non-culture of granulose cells produced a 32 kDa band. Molecular weight of inhibin was measured by Western Blot. The 32 kDa band of SDS PAGE product appeared on Western Blot result was inhibin molecules produced by granulose cells collected fom culture and non-culture of granulose cells that can be identified by Mab-inhibin. Product of IEF gel electrophoresis suggested that inhibin molecule collected from culture of granulose cells has no charge at isoelectric points ranging from 5-6, depends on its total amino acid composition.

Abstract

The objective of this research is to know Aceh cattle follicle dynamic under environmental heat stress condition. This research was conducted on December 2012 until August 2013. Animals used in this research were 20 Aceh cattle aged 5-8 years old, weighing of 150-250 kg, and had at least 2 regular cycles. All cattle used were clinically in good body condition score. The cattle were divided into two groups of 10, used in two different period of times (December-January and July-August) to examine the effect of environmental heat to their follicle dynamic. Each group is separated into two different keeping management; one group was kept in pens while the others in the pasture, 5 cattle in each management group. Research timing was based on information acquired from Indrapuri Agency for Meteorology, Climatology, and Geophysics (BMKG) which predicted that extreme weather would last from July to August while December to January would be relatively normal in Aceh region. All cattles estrous cycle were synchronized by 5 mg/mL of PGF2 intramuscularly (Lutalyse, Pharmacia Upjohn Company, Pfizer Inc.). Ultrasonography examination was performed to monitor ovary follicles growth and dynamic during one cycle. Days during ovulation marked by standing heat was regarded as Day 0 of estrous cycle. Follicular dynamic examination during estrous cycle on December-January and also on July-August, both penned or pastured cattle showed the follicle waves that was 3 follicle growth waves. The size of follicle growth on first wave (1st DF) on cattle kept in pen on July-August and December-January were relatively similar. The size of follicle growth on first wave for cattle kept in pasture on July-August and December-January were relatively similar. To conclude, Aceh cattles follicle dynamic is not change during environment heat stress condition and is not affected by different cattle-keeping management.

Abstract

The objective of this study was to identify the type of specific glycoconjugates and its distribution in testicular spermatogenic cells in muntjak (Muntiacus muntjak muntjak) based on lectins histochemistry. An adult male muntjak aged 4-5 years old in hard antler period was used in this study. Testicular tissue was fixed in Bouin solution and processed histologically. Histochemistry method was performed using six types biotinylated lectins such as peanut agglutinin (PNA), soybean agglutinin (SBA), wheat germ agglutinin (WGA), ricinus communis agglutinin (RCA), concanavalin A (Con A), and ulex europaeus agglutinin I (UEA I) with 20 g/ml of concentration for PNA lectins and 15g/ml for other type of lectins. The results showed that glycoconjugates were detected by all type of lectins except UEA I in testicular spermatogenic cells with variation in distribution pattern and also the intensity of lectins binding. Glycoconjugates -galactose, -glucose, mannose, Nacetylgalactosamine, N-acetylglucosamine and sialic acid were stained intensely by lectins in golgy-cap phase and acrosomal phase of spermatids. Glycoconjugate N-acetylgalactosamine was the sugar residues which distributed abundantly that marked by positive reaction with PNA, SBA, and RCA lectins. In conclusion, glycoconjugates are detected in testicular spermatids cells of muntjak indicated that glycoconjugates have an important role in spermatogenesis particularly in spermiogenesis.Key words: glycoconjugates, lectins, spermatid, spermatozoa, muntjak

Abstract

This research aimed to determine the optimum time for early pregnancy diagnosis in dwarf goat by trancutaneous ultrasonography and to determine ultrasonography imaging of dwarf goat pregnancy since insemination until embryo formation. Animal used in this research were 3 productive female goats with normal estrus cycle and 1male goat. The female goats were kept in separation pen from the male goat. The grasses were fed three times a day and additional feed were fed in the morning and afternoon with the water was given ad libitum. The goats were synchronized with intramuscular double injection of 1 ml estron/each female goat with 11 days interval. The observation of estrus was examined using male goat following the second injection of estron. The sign of estrus in female goats were characterized with standing immobile and allow the male goat to mount them. If the signs had been evident, the female goats were naturally mated. Pregnancy was determined by the presence of the embryonic vesicle by isoechogenic until hyperechogenic visualization surrounded by hypoechogenic of the embryonic fluid. The result of the transcutaneous ultrasonography in dwarf goat pregnancy showed the presence of embryonic vesicle on day 14 and embryo with isoechogenic visualization was detected on day 24 of pregnancy.Key words: dwarf goat, early pregnancy, transcutaneous ultrasonography

Abstract

This research was aimed to find out the relationship between the diameter of follicle and thedifferent of follicle number on oocyte quality of local goat. The oocyte originated from the ovary was takenfrom the Slaughterhouse in Banda Aceh. The ovary was aspirated in the Histology Laboratory ofVeterinary Medicine Faculty of Syiah Kuala University, Banda Aceh. This experiment consisted of twostages, the follicles were selected and divided into 3 groups according to their diameter size. The smalldiameter size 2 mm, medium size 2-5 mm, and big size 5 mm. The second, the ovaries were dividedinto three groups based on number of follicle, i.e; 1(5; 2(6-10); and 3 (11). The diameters of oocytetaken from the three groups of follicle size were measured by using eyepiece micrometer, while the oocytemorphology was categorized into 4 groups. The result of regression data indicated that the biggest folliclediameter yielded the oocyte that had bigger diameter, too. The model of regression is y = 0.955 + 0.157x, y is the diameter of oocyte and x is the diameter of follicle. The close relationship (r) between the diameter offollicle and the diameter of oocyte was 0.967. There are significant differences (P0.05) between the size offollicle and the morphology of oocyte. The oocytes originated from larger follicle tend to have bettermorphological appearance than the oocyte originated from smaller follicle.Keywords: oocyte, follicle
