  • Pancreatic endocrine cells of the native Korean goat were investigated immunocytochemically at electron microscopic level. All glucagon-, insulin-, somatostatin- and pancreatic polypeptide(PP)-immunoreactive cells were showed chromogranin(CG) immunoreactivity in the secretory granules of each cells. In addition, bovine pancreatic polypeptide immunoreactivity was found to be colocalized in the secretory granules of the glucagon and insulin cells. These observations support that chromogranin is available as the marker of pancreatic endocrine cells on the native Korean goat and BPP colocalized in the secretory granules of glucagon and insulin cells.

  • The distribution of glucagon-immunoreactive cells in the pancreas during various developmental stages (fetus, neonate, 1-month-old, 6-month-old and adult) of the Korean native goat was investigated by immunohistochemical methods. The varying distribution and frequency of glucagon-immunoreactive cells in the pancreas of the Korean native goat were observed. The glucagon-immunoreactive cells were detected in both exocrine and endocrine portions (pancreatic islets) at all developmental stages and also in ducts of the 6-month-old and adult. The relative frequencies of glucagon-immunoreactive cells increased in the pancreatic islets and ducts with age, but decreased in the exocrine portions. Generally, they were distributed in the interacinar spaces or marginal zone of the pancreatic islets during all stages of development. However, the cell distributions of the pancreatic islets in the neonate divided into two types: 1) ones which were distributed in the inner zone, and 2) others in the peripheral zone.

  • A survey was performed on the outbreak of listeriosis in a Korean native goat in Animal Breeding Station of Gyeongsang National University, Chinju, Korea. Clinical signs in the affected goat were fever, dullness, inappetence, nasal discharge, slobbering, dysphagia, circling, incoordination, recumbency, unilateral facial paralysis, torticollis, dyspnea, spasmodic paddling movement of the limbs and death at 6 days after onset. No significant gross lesions were seen. The histopathological lesions were consisted of perivascular edema and cuffs by round cells and microabscess with infiltration of neutrophils, lymphocytes and macrophages in the cerebrum. Gram-positive organism was observed in the microabscess lesions. Listeria monocytogenes was isolated exclusively from the brain tissue by cultural examination and the lesions induced by experimental infection with the isolate were characterized by severe conjunctivitis in rabbit and hepatic necrotic foci in mouse. This seems to be the first report of listeriosis in Korean native goat.

  • This study was carried out to investigate the origin, insertion, direction of muscle fibers and structure of the ear muscles of the Korean native goat. The description was based on the dissection of fifteen the Korean native goats with embalming fluid. The results were as follows: 1. The ear muscles of the Korean native goat were composed of the M. zygomaticoauricularis, M. scutuloauricularis superficialis, M. scutuloauricularis profundus, M. frontoscutularis, M. interscutularis, M. parietoauricularis, M. cervicoscutularis, M. cervicoauricularis superficialis, M. cervicoauricularis medius, M. cervicoauricularis profundus, M. auricularis profundus posterior and M. parotidoauricularis. 2. The M. frontoscutularis clearly seperated into temporal and frontal parts in 6 cases. 3. The M. scutuloauricularis profundus clearly separated into major and minor parts. 4. The M. zygomaticoauricularis blended with the M. parotidoauricularis near its insertion, but not with the M. scutuloauricularis.

  • For purposes of substantiation of organizing measures on industrial processing of goat's and sheep's milk in Mongolia and the production of dairy products we have conducted the studied physico-chemical characteristics of the Mongolian goat's and sheep's milks especially to recognize amino acids, minerals and vitamins in the milk and compare with the Mongolian cow's milk. And also was studied fractional structure of goat's milk whey proteins.

  • Malignant catarrhal fever (MCF) is a systemic disease of ruminants caused by a gamma herpesvirus, ovine herpesvirus 2 (OvHV-2). Four 1-year old goats (Capra hircus), which were infected with MCF virus, OvHV-2, by being housed together with MCF virus-infected seep, were referred with a I-month history of chronic dermatitis. On the other hand, MCF virus-negative goats, which were isolated for negative control, had not those kinds of skin problems. Examination of the affected goats revealed generalized alopecia, patchy erythema, and superficial erosions with histologic evidence of mural folliculitis. Fungal culture tests and external parasite tests with the scraping skin samples were negative. However, polymerase chain reaction revealed the existence of MCF virus DNAs in the lesion. These results suggested that MCF virus may induce mural folliculitis and alopecia in goat.

  • The extent to which farmers use the recommended husbandry practices by farmers raising goats in southern Thailand was investigated. Base-line data was collected by interviewing 297 farmers and the constraints to the use of recommended husbandry practices were examined for these farmers in the Chana district, Songkhla province of southern Thailand. The number of farmers using the various recommended husbandry practices was low. An extension program is needed to encourage the use of recommended goat husbandry practices in target areas of southern Thailand to provide a better understanding of the most effective goat husbandry practices.

  • Capacitated goat spermatozoa generated diacyl glycerol (DAG) when suspended in Krebs-Ringer bicarbonate medium and induced by progesterone or $Ca^{2+}$ ionophore A23187. We have added Sn-1-oleoyl-2-acetyl glycerol externally, to study the effect of DAG in goat sperm acrosomal exocytosis. Addition of neomycin abolished the DAG generating capacity of progesterone in a dose dependent manner, suggesting the involvement of a phosphoinositidase C activated phospholipase C system in the process. The level of increase in phosphatidic acid was considerably low and was produced well after the DAG generation thereby suggesting the involvement of a DAG kinase which phosphorylates DAG to produce PA. The inhibition of progesterone mediated effect by inhibitors of $GABA_A/Cl^{-}$ channel and $Ca^{2+}$ channels further supports the evidence that the events of binding of agonist to the receptor(s), opening of $Ca^{2+}$ channels and the activation of phospholipase C are reconciled to perform the function of acrosome reaction in capacitated goat spermatozoa.

  • A case of chronic cholangiohepatitis associated with Eimeria spp. is reported in a 6-month-old, male, native Korean goat. The goat died after having a 1-week history of diarrhea, anorexia and weight loss. At necropsy, numerous multifocal to coalescing, pale and mottled red foci were present throughout the liver. Histologically, numerous coccidian parasites in both sexual and asexual stages were found in the intrahepatic biliary epithelia and bile duct lumens. Based on the light microscopic and ultrastrastructural features, the parasites present in the liver were compatible with the genus Eimeria ; however, the species was not speciated.
