Sari et al. 2012. Study on the Biological Characteristics of Pegagan Duck. JLSO 1(2):170-176. Pegagan duck is one of the local geneticÂ and biodiversity resources in South Sumatera which needs to be conserved and developed. So far, scientific data of Pegagan duck as a biodiversity resource were relatively limited compared to other local ducks. The aim of this experiment was to investigate and identify egg variability of Pegagan duck. This experiment started by collecting 500 Pegaganâ€™s egg from three districts, namely Tanjung Raja, Inderalaya and Pemulutan, Ogan Ilir Regency, Sumatera Selatan. Collected eggs were cleaned with lysol 2.5% prior to putting into the hatching machine. During hatching process, the eggs were rolled up and down from the 3th d until the 25th d. Egg candling was done three times: day 5, day 13 and day 25. The results showed that initial weight of parent (G0) male and female Pegagan duck was 36.87 g and 36.73 g, respectively. Meanwhile,Â F1 generation was 36.90 g for male and 37.09 g for female. The growth pattern between male and female duck was relatively the same. Growth curve which showed the relationship between body weight and age of duck formed a sigmoid curve. The growth differences between male and female duck occured at the 5th week. Body weight of male duck wasÂ higher than female duck. The highest body weight found at theÂ inflexion point for both male and female duck for parent (G0) was at the 4th week and for F1 was at the 5th week.Â At the first laying, the body weight of Pegagan duck for parent (G0) reached 1541.17Â±132.19 g, whereas for F1 reached 1605.34Â±167.19 g. Parent (G0) and F1 of Pegagan duck layed at the average age of 153 and 154 d, wherein 30% layed at the age of < 151 d and 60% at the age of 151-170 d.These results were expectedly become database and guidance for the conservation and sustainable development of pegagan duck.

polymorphism of blood protein pegagan duck by PAGE methodABSTRACT. Pegagan duck is one of local duck species which comes from Ogan Ilir (OI) Regency, South Sumatera. This species is not popular, yet. But, it has spread out along Ogan river which comprises of three districts e.g Tanjung Raja, Inderalaya and Pemulutan. The ecosystem in this three districts is dominated by swampy area. As far, there is relatively limited information of Pegagan duck compared to another local duck. So, for the first step was done a reseach to identify genetic characteristic from blood protein analyses by electrophoresis method. It is expected that this information will become the bases in determining of the policy of Pegagan duck development. Polymorphism analyses of blood protein was done with 9 duck samples which taken randomly from 400 pegagan ducks. Protein locus observed were albumin (Alb), post albumin (Pa), transferrine (Tf), post transferrine-1 (Ptf-1), and post transferrine-2 (Ptf-2). Polymorphism analyses of blood protein of pegagan duck was characterized by allele A in locus Transferrine (TfA), Post transferrine-1 (Ptf-1A) and Post transferrine-2 (Ptf-2A) . Genetic diversity based on blood protein of Pegagan duck showed that gen frequency value in a range of 0,11 – 0,94 and high heterozygosis value that was 0,62 %.

Varanus salvator bivittatus has a pair of hemipenes, which is macroscopic anatomically like the copulatory organ in other amniotes, cylindrical-shaped (truncus) with quite flexible, and it located on the base of the caudal tailof the cloaca. However, information about the microscopic anatomy of hemipenes of this animal is scientifically unpublicized. Therefore, the aim of this research is to study the microscopic anatomy of hemipenes of male Varanussalvator bivittatus. The animals were sacrificed by exsanguination under deep anesthetized and fixed in 4 % paraformaldehyde through perfusion then observed visceral site and morphometric. Histomorphological evaluationwas obtained by paraffin preparation with section thickness of 3-4 μm then stained in Hematoxylin-Eosin (HE) and Masson’s Trichrome (MT). The results showed that truncus of hemipenes was lined by stratified squamousepithelium and supported with thick of dense connective tissue and contain cavernous body and blood vessels are found, the muscles not found. The presence of connective tissue that supported in the down part sometimesmake hemipenes are rigid while prurient condition. In the caudal of truncus hemipenes there is retractor muscle of hemipenes which arranged by striated muscles. Hemipenes is flexible because contain with much of blood vesselthat found in truncus hemipenes.

The study aimed to analyze the dynamics of the development of cortical and medullary cells of adrenal gland in the long-tailed macaque (Macaca fascicularis) during pre- and postnatal period. The samples of adrenal glands were taken from 5 fetuses aged 70, 85, 100, 120, and 150 days of gestation, a newborn aged 10, and an infant aged 105 days old. The samples of the adrenal glands were stained with hematoxylin-eosin and Masson trichrome (Goldner’s modification). The results showed that the fetal adrenal cortex consisted of a definitive and fetal zones, but in the late gestation (fetus aged 150 days of gestation), the transitional zone appeared between both zones. At the postnatal period, the definitive zone changed to glomerulosa zone, while the outer cells of the transitional zone changed to fasciculata zone which radially arranged. The results indicated that the fetal zone was present until birth and it will disappear gradually after birth. The medullary cells were found at the fetal stages as an irregular structure of small islands of chromaffin cells in the fetal zone. This structure migrated slowly to the center of the adrenal glands. The characteristics of mature chromaffin cells were found in the adrenal glands at postnatal period. In conclusion, the cortex adrenal of the newborn of long-tailed macaque consisted of zona glomerulosa, zona fasciculata, zona transitional, and the remaining fetal zone that has dissapeared gradually after birth.

The morphological characteristics of the stomach and esophagus of five adults bandicoot (Echymipera kalubu) with average 1.16±0.29 kg in body weight and 38.2±4.76 cm in body length were studied macroscopically, microscopically and histochemically. The bandicoot esophagus were found relatively long about one third of body length. The esophageal glands were identified along the esophagus and the number decreased gradually from cranial to caudal region. In addition of smooth muscle, skeletal muscles were also examined in the external muscle layer of esophagus up to the esophageal junction. The stomach of the E. Kalubu had short lesser curvature and three glandular regions of cardiac, fundic and pyloric glands were observed, respectively. The cardiac glands area was small and concentrated in the cranial part of the stomach. The fundic glands area occupied about half parts of the stomach. Mucous surface epithelial cells, mucous neck cells, parietal cells and chief cells were found in the entire fundic gland. The parietal cells were the most abundant cells in the major curvature distributed from the basal to neck area of the glands, but few in the minor curvature. Chief cells were mostly distributed in the basal gland. The pyloric glands region was observed in caudal part of the stomach. Staining with alcian blue-periodic acid Schift (AB-PAS) showed various distribution and intensity of neutral and acid mucopolysaccharides in the esophageal and stomach mucosa. High concentration of neutral and acid mucopolysaccharides were detected in esophageal and stomach glands with various concentration. Morphological characteristics of the esophagus and stomach were assumed to be related to the digestive processes in the gastrointestinal tract of bandicoot.

The study aims to determine the histological structure of the testes, ductus epididymidis and ductus deferens of Varanus salvator bivittatus. The tissue samples were obtained by the histological techniques preparation with thickness section is 3-4 µm then stained using hematoxylin-eosin (HE) and Masson's Trichrome (MT). The result showed that testes are covered by tunica vaginalis and tunica albuginea (tunica fibrous and tunica vasculosa). Tubulus seminiferous as a parenchyma are found in lobules of testes which are formed by septum as extension of tunica albuginea. Tubulus seminiferous is composed by layers of germinal epithelium cells consist of spermatogenia, Sertoli cell, spermatocyte and spermatid which is developed further to be spermatozoa in the lumen of tubulus. Among the tubulus seminiferous, there are groups of epithelioid cells called Leydig cells. The end of tubulus seminiferous formed ductus epididymidis which then ended up and known as ductus deferens. Epididymis is covered by dense connective tissue. Ductus epididymidis is divided into three segments: cranial, medial and caudal. It is lined by pseudostratified columnar epithelium which is varied in its thickness, amount and diameter of lumen. Lumen of the ductus deferens was lined by pseudostratified ciliated columnar epithelium and thin muscularis mucosal layer and thick circular smooth muscle were covered externally.Key words: Varanus salvator bivittatus, testes, ductus epididymidis, ductus deferens, micromorphology
