The purpose of this study was to make fundamental ultrasonographic observations of kidney and urinary bladder in Korean native goat. The position, dimensions, and structure of the kidneys and bladders In 7 male Korean native goats were determinded by use of ultrasonography. A 3.5%.MHz linear transducer was used. All examinations were performed on goats in lateral recumbency under sedation. The left kidney was 4.2 to 5.9 cm long, 2.5 to 3.6 cm wide, and 2.4 to 3.2 cm deep. Diameter of the parenchyma and renal sinus of the left kidney ranged between 0.7 and 1.3 cm and 0.7 and 1.4 cm, respectively. Circumferences of the medullary Pyramids varied between 1.3 and 1.9 cm. Similar ultrasonic measurements were obtained for the right kidney. The diameter of the urinary bladder varied between 2.1 and 5.4 cm in the goats. It was concluded that the ultrasonographic findings described in this study can be used as references for diagnosis of morphologic changes in the kidney and urinary bladder of Korean native goat.

This experiment was carried out to evaluate the effect of pasture type on behavior pattern, change of body type and daily gain of Korean native goat at the College of Natural Science of Kon-KuK University in Chungju. The results are summarized as follows : Relative coverage of native herbage at the pasture area was 62% in initial grazing period and that final grazing period decreased by 36%. while pasture plants increased from 17 to 42%. In brush area, Quercus serrata. Quercus dentutu, Prunus surgenrii and Rhus vemicrflua of high palatability decreased with increase in grazing period. but Rhododendron mucronulatum and Rhodendrorl schlippenbachii of low palatability tended to increase. Average crude protein content at the pasture area(12.3Q) during grazing period was higher than that at the brush area(10.2). However, ADF and NDF content was lower than brush area. Ca, Mg and Na of mineral content showed highly at the brush area during the grazing period. but Na showed highly at the pasture area. Eating time Korean native goat was not different between pasture area(369 min.) and brush area(361 min.), but ruminating time showed highly at the pasture area(441 min.). Average ratio of GTlRT at the pasture and brush area was not different m 0.88 and 0.87, respectively. All body type(withers height, body length, shin circum, hip height, hip width and chest girth) showed highly that pasture area compared to brush area during the grazing periods. The daily liveweight gain showed 60.6 and 48.98 at the pasture and brush area, respectively.

The present study was undertaken to investigate the morphological characteristics of trigeminal nerve in the Korean native goat by macroscopic methods. Trigeminal nerve was originated from the lateral side of pons, and extended shortly forward to form trigeminal ganglion at the opening of oval foramen. Thereafter this nerve was divided into maxillary, mandibular and ophthalmic nerve. Ophthalmic nerve gave off the zygomaticotemporal branch, frontal nerve, frontal sinus branch, and was continued as the nasociliary nerve. Maxillary nerve gave rise to the zygomaticofacial branch, accessory zygomaticofacial branch, communicating branch with oculomotor nerve, pterygopalatine nerve, caudal superior alveolar branch, malar branch and was continued as the infraorbital nerve. Mandibular nerve was divided into the masseteric nerve, buccal nerve, lateral pterygoid nerve, medial pterygoid nerve, nerve to tensor tympani m., auriculotemporal nerve, and furnished the inferior alveolar nerve and lingual nerve as terminal branches. The course and distribution of the trigeminal nerve in the Korean native goat appeared to be similar to that in other small ruminants such as sheep and goat. But the main differences from other small ruminants were as follows : 1. There was no accessory branch of the major palatine nerve. 2. The caudal superior alveolar branch was directly branched from the maxillary nerve. 3. The communicating branch with oculomotor nerve was originated from maxillary nerve or common trunk with zygomaticofacial branch. 4. The malar branch arose from the maxillary nerve at the rostral to the origin of the caudal superior alveolar branch. 5. The inferior alveolar nerve originated in a common trunk with the lingual nerve. 6. The mylohyoid nerve arose at the origin of the inferior alveolar nerve. 7. The zygomaticotemporal branch was single fascicle, and gave off lacrimal nerve and cornual branch. 8. The base of horn was provided by the cornual branches of zygomaticotemporal branch and infratrochlear nerve of nasociliary nerve.

The anthelmintic efficiency of nitroxynil(Trodax) at a dose rate of 10mg/kg was tested in naturally infected Korean native goat (Black goat) against Fasciola hepatica, Eurythrema pancreaticum, and Paramphistomum sp. The drug was administered with injection subcutaneouslly and the efficiency was measured by faecal examination microscopically. The results obtained were summarized as follows: 1. The anthelmintic efficiency of nitroxynil against Fasciola hepatica was shown 33.3% on day 7, 88.9% on day 14 and 94.4% on day 28 after the administration of the drug, respectively. The reduction rates of egg per gram of faeces (E. P. G.) against Fasciola hepatica in faecal examination were shown 86.8% on day 7, 97.7% on day 14, and 99.7% on day 28 postmedication. 2. The anthelmintic efficiency of nitroxynil against Paramphistomum sp. was shown 0% on day 7, 10.5% on day 14, and 36.8% on day 28 after the administration of drug. The reduction rates of E. P. G. against the parasite were shown 13.2% on day 14, and 39.4% on day 28 postmedication. 3. The anthelmintic efficiency of nitroxynil against Eurythrema pancreaticum was shown 0% on day 7, 16.6% on day 14, and 25% on day 28 after the administration of the drug.

The supplementation effects of sea tangle powders were determined for the meat quality in Korean native black goats. A total 90 castrated male black goats at 3-month age were divided into 3 dietary treatment groups: control (basal diet + mineral block), T1 (0.3% sea tangle feeding with the basal diet), T2 (0.9% sea tangle feeding with the basal diet). At 9-months feeding, 10 goats per treatment group were slaughtered, and the longissimus dorsi muscle samples were vacuum-packed, and subsequently analyzed for physicochemical evaluations. Analysis revealed decrease in the shear force and TBARS values of meat in the sea tangle dietary groups (p < 0.05). The T2 group exhibited increased levels of unsaturated fatty acids such as C16:1, C18:1, C18:2, and C20:4 (p < 0.05). The content of free amino acids with desirable taste such as aspartic acid, glutamic acid, glycine, histidine, and serine were higher in T2, whereas alanine content was higher in both sea tangle dietary groups, as compared to control (p < 0.05). These data indicate that feeding dietary sea tangle as an alternative mineral source results in an improvement in the physicochemical profiles of goat meat.

This study was conducted to investigate the genetic diversity and genetic taxonomic relationships between Korean native black goat (KNBG) populations and crossbred goats. The 45,658 common single nucleotide polymorphisms present in the KNBG strain and crossbred goat were used for the analysis. The expected and observed heterozygosity (which can be indicators of genetic diversity) were in the order of crossbred, Gyeongsang National University, Jangsu, then the Tongyeong strains. The variance component represents the degree of genetic diversity between groups. The highest variance (19.98 %) was between the Dangjin and Gyeongsang National University strains. The lowest variance (8.87 %) was between the Jangsu and Tongyeong strains. In addition, the genetic distance between the populations showed that Jangsu and Tongyeong formed one branch (they were very similar genetically). The Dangjin and the Gyeongsang National University strains appeared to form a second branch. Furthermore, the crossbred formed one branch with the Dangjin and the Gyeongsang National University strains. Therefore, the results of this study can be used as basic data to reduce unnecessary inbreeding and genetic resource flow between the KNBG populations. The basic data indicates the uniqueness of the genetic resources of the domestic lineage. These findings provide a basis for differentiating KNBG and Crossbred goats to use to improve the desirable characteristics of this species.

The objectives of the present study were to initiate cloning of Korean native goat by somatic cell nuclear transfer (NT) and to examine whether unovulated (follicular) oocytes can support the same developmental ability of NT embryos as ovulated (oviductal) oocytes after hCG injection in stimulated cycles of the goat. The in vivo-matured and immature oocytes were collected from the oviducts and follicles of superovulated does, respectively, and the immature oocytes were maturated in vitro. Ear skin fibroblasts derived from a 3-yr-old female Korean native goat were used as the donors of nuclei or karyoplasts. Following fusion, activation and in vitro culture to a 2- to 4-cell stage, 49 in vitro-derived and 105 in vivo-derived embryos were transferred to 6 and 17 recipient does, respectively. One doe and three does of the respective groups were identified as pregnant by ultrasonography on day 30 after embryo transfer. However, only one doe, which had received in vivo-derived embryos, delivered a normal female kid of 1.9 kg on d 149. The cloned kid gained more weight than her age-matched females as much as 87% during the first 4 mo after birth (17.7 vs. $9.4{\pm}0.8$ kg) and reached puberty at 6-mo age a few months earlier than normal female does. The telomere length of the kid, which was similar to that of the donor fibroblast at 2-mo age, decreased 8% between 2- and 7-mo ages. Moreover, at 7-mo age, she had 21% shorter telomere than her age-matched goats. To our knowledge, this is the first case in which a cloned animal born with a normal weight exhibited accelerated growth and development. The unusually rapid growth and development of the cloned goat may have resulted from SCNT-associated epigenetic reprogramming involving telomere shortening.
