Objective: This study aims to compare the reproductive performance of Boerka goats and Gembrong goats.Methods: The research was conducted at the Sei Putih Slaughter Goat Research Workshop in Deli Serdang, North Sumatra. In this study, male Boerka (n=3) and Gembrong (n=3) goats, aged 3 years and having the same average Body Condition Score (BCS) of 3.83±0.29, were used. Reproductive performance observed included scrotal circumference, libido score, and semen quality macroscopically (volume, color, odor, and consistency) and microscopically (concentration, motility, viability, and abnormalities). The data collected was tabulated and analyzed by t test.Results: Of all the parameters of reproductive performance examined, it is known that only the parameters of semen volume (ml) and sperm concentration (x106 cells/ml) showed a significant difference (P<0.05) between Gembrong goats vs. Boerka goats with values of 0.50±0.0 vs. 1.0±0.20 and 1.557±712 vs. 4.500±317.65, respectively, while the other parameters did not show a significant difference (P>0.05).Conclusions: It was concluded that the volume and concentration of Boerka goats were higher than Gembrong goats.

The presence of glycoconjugates in caput, corpus, and cauda epididymis of the Javan muntjacs was performed using lectin histochemical method. The epididymis organs were obtained from two adult male Javan muntjacs in hard antler stage and then immediately fixed in Bouin’s solution and processed in histological manner. Six types of biotinylated lectins namely 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) were applied to detect the specific glycoconjugates in the epididymal tissue of muntjacs. The result showed the presence of glycoconjugates were detected by five types of lectins except UEA I in caput, corpus, and cauda epididymis with specific distribution and also the intensity of lectins binding. Glycoconjugates β-galactose, β-glucose, mannose, N-acetyl-galactosamine, N-acetyl-glucosamine, and sialic acid were stained with various intensity in epithelial cells, basal cells, stereocilia, spermatozoa, and stroma of caput, corpus, and cauda epididymis. The presence of sialic acid on the surface of spermatozoa detected by WGA are thought to be play a role on sperm protection during their maturation and transit along epididymal lumen. In conclusion, the difference of glycoconjugates distribution pattern and lectin binding in the epididymal caput, corpus, and cauda of the Javan muntjac indicates the regional differences in epididymal function in spermatozoa maturation.

Penelitian ini bertujuan mengetahui perbandingan efektivitas pemberian hormon prostaglandin komersial yang berbeda terhadap persentase berahi dan kebuntingan kambing peranakan ettawa. Kambing betina yang digunakan mempunyai kriteria umur 2,5-3,5 tahun, sehat, tidak bunting, minimal 2 bulan pasca partus, sudah pernah beranak, dan mempunyai bobot badan yang relatif sama. Di samping itu digunakan 2 ekor kambing jantan untuk membantu deteksi berahi. Hewan percobaan dibagi atas 3 kelompok perlakuan, masing-masing kelompok terdiri atas 5 ekor kambing. Kelompok perlakuan I diinjeksi dengan 2,5 ml Lutalyse (dinoprost tromethamine 5 mg/ml dan benzil alkohol 1,65%), kelompok perlakuan II diinjeksi dengan 0,5 ml Prostavet (etiproston 5 mg/2 ml dan ethylen dioxy 15 mg/2 ml), dan kelompok perlakuan III diinjeksi dengan 1,5 ml Capriglandin (dinoprost tromethamine 5,5 mg/ml dan benzil alkohol 12,0 mg/ml). Penyuntikan dilakukan 2 kali secara intramuskuler dengan interval 10 hari setelah penyuntikan pertama. Kambing-kambing yang memperlihatkan gejala berahi dikawinkan secara inseminasi buatan. Diagnosis kebuntingan dilakukan dengan menggunakan USG 30 hari setelah inseminasi. Data onset berahi dianalisis menggunakan analisis varian, sedangkan persentase berahi dan kebuntingan dianalisis secara deskriptif. Onset berahi ketiga kelompok perlakuan masing-masing adalah 40,8±0,57 36,0±0,57 dan 50,4±1,52 jam (P0,05). Persentase berahi pada ketiga kelompok adalah sama yakni 100%, sedangkan persentase kebuntingan pada kelompok I, II, dan III masing-masing adalah 100, 80, dan 60%. Dari hasil penelitian dapat disimpulkan bahwa onset dan persentase berahi tidak dipengaruhi oleh ketiga prostaglandin komersial yang berbeda tetapi berpengaruh terhadap persentase kebuntingan kambing PE.

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 cattle’s estrous cycle were synchronized by 5 mg/mL of PGF2α intramuscularly (Lutalyse™, Pharmacia Upjohn Company, Pfizer Inc.). Ultrasonography examination was performed to monitor ovary follicle’s 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 cattle’s follicle dynamic is not change during environment heat stress condition and is not affected by different cattle-keeping management.

The objective of this study was to characterize the morphology of ovary from slaughtered Aceh cow and measuring the concentration of estradiol in the follicular fluid to examine the potential utilizing for in-vitro fertilization (IVF) development in Aceh cattle. In total, 30 pairs of ovaries were collected from 30 Aceh cattle slaughtered at Banda Aceh abattoir. Morphological characteristics of ovaries observed were the size of ovaries, weight of ovaries, number of follicles, the diameter of follicles, corpus luteal (CL), and volume of follicular fluid. The follicular fluid was aspirated using a disposable syringe and analyzed the estradiol concentrations using enzyme-linked immunosorbent assay (ELISA). The follicles were grouped into 3 categories based on the diameter (Ø) of follicles: small follicles (Ø 1 - 5 mm), medium follicles (Ø 5 - 8 mm), and large follicles (Ø 8 mm). The morphological characteristic of ovaries varied between right and left ovaries in which right ovaries showed bigger size and weight compared to the left ovaries (P0.05), whereas the number of follicles and follicular fluid did not significantly different (P0.05). The concentrations of estradiol in follicular fluid of large and medium follicles were significantly higher compared to small follicles (P0.05), whereas the concentration of estradiol between large and medium follicles, did not significant different (P0.05). In conclusion, the follicles from abattoir can be used as potential oocytes resources to support IVF development for Aceh cattle in the future. The follicular fluid provided from these follicles can be an alternative for in vitro maturation media of oocytes due to containing high estradiol concentrations.

A male eight-year-old Sumatran elephant, was diagnosed with an acute accidental injury due to snare of a steel cable in the distal right front leg (radiocarpal joint). The general physiological condition of the elephant is still within normal limits and the state of the wound has not shown any severe pathological signs so that the prognosis is fausta. Management of snare wounds is carried out with a conservative approach according to the procedure. Elephant care and monitoring of recovery are carried out at the Elephant Conservation Center, at Saree, Aceh Besar. Follow-up examinations in the form of routine hematology and blood chemistry were also carried out because wound healing was past its optimal period. Laboratory examination results showed that the number of leukocytes and differential leukocytes tended to increase, while the number of platelets, erythrocytes, hemoglobin, hematocrit, total protein, albumin, and glucose tended to decrease from normal references. The results of the supporting examinations are then interpreted as a basis for better animal recovery including providing complete nutrition to animals. It can be concluded that steel wire snare wounds to the legs and the resulting injuries can be cured by treating wounds and improving the quality of feed given to Sumatran elephant patients.

The semen quality of Gembrong goats is lower than other goats and may be related to the low concentration of testosterone hormone. Implementation of reproductive technology using prostaglandin F2α (PGF2α) hormone is beneficial to increase the testosterone hormone in Gembrong goats. This study aimed to determine the effect of PGF2α injection on increasing testosterone levels in Gembrong goats. Male Gembrong goats (n=4), aged 2.5-4 years with similar body condition scores (BCS=3) were used in this study. Goats were divided into two treatment groups (n=2). Goats in group 1 (G1) were injected intramuscularly with 1 ml PGF2α (75 Î¼g), while those in group 2 (G2) were injected with 1 ml physiological NaCl. Semen collection was carried out 30 minutes after treatment using an artificial vagina. Testosterone levels were measured using the enzyme-linked immunosorbent assay (ELISA). The collected data was tabulated and analyzed descriptively. The results showed that the average testosterone concentration of G1 was higher than G2 with respective concentrations of 6.41 ± 0.70 and 2.81 ± 1.75 ng/ml. It was concluded that administration of PGF2α in vivo could increase testosterone concentration in Gembrong goats.

Cedera kepala merupakan masalah pada struktur kepala akibat mengalami benturan yang berpotensi menimbulkan gangguan pada fungsi otak. Cedera kepala cenderung mengalami masalah yang komplit karena akan terjadi masalah pada otak dan saraf. Masalah ini dapat berupa luka ringan, memar di kulit kepala, bengkak, perdarahan, patah tulang tengkorak, atau gegar otak. Penyebab kematian atau kecacatan yang dapat terjadi apabila cedera kepala tidak mendapatkan pertolongan yang benar pada saat kegawatdaruratan. Melihat besarnya dampak yang dapat diakibatkan dari cedera kepala perlu adanya pencegahan dan sistem pendukung yang intensif, sehingga diharapkan masalah yang ada dapat teratasi dan komplikasi yang mungkin terjadi dapat dihindari secara dini, serta tindakan pencegahan yang komprehensif. Pencegahan yang dilakukan untuk mengurangi resiko cedera kepala di dalam masyarakat adalah dengan menggunakan alat pengaman saat berolahraga, selalu menggunakan alat keselamatan seperti helm atau pelindung kepala apabila bekerja di lingkungan yang berisiko menimbulkan cedera kepala. Memasang pegangan besi di kamar mandi dan di samping tangga untuk mengurangi risiko terpeleset Memastikan lantai selalu kering dan tidak licin. Memasang penerangan yang baik di seluruh bagian rumah. Memeriksa kondisi mata secara rutin, terutama jika mengalami gejala gangguan penglihatan, seperti buram atau penglihatan berbayang. Pada kegiatan pengabdian masyarakat ini, telah dilakukan penjelasan tentang pencegahan resiko cedera kepala pada 20 orang dan peserta mampu menjelaskan tentang pencegahan resiko cedera kepala.
