The morphological development of uterus in 60-, 90-, 120-day-old fetuses at gestation and neonates of Korean native goats were investigated by light microscopy. 1. In the 60-day-old fetuses, uterine walls differentiated and divided into the endometrium, myometrium and perimetrium. 2. In the 90-day-old fetuses, the blood vessels appeared in the uterine walls, in the 120-day-old fetuses the nodules (primordial caruncles) appeared first in the endometrium. 3. In the 120-day-old fetuses, the gland primordia observed on the uterine epithelium. In the neonates, the developing uterine glands were more number and deeper than those of 120-old fetuses. 4. PAS reaction of the mucosa cells in the endometrium was reacted weak, moderate and strong at 90-, 120-day-old fetuses and neonates, respectively.

The mean birth weight and weaning weight estimated from 777 kids from 30 bucks of Teddy goats were $1.67{\pm}0.31$ and $8.50{\pm}2.18kg$, respectively. The estimates of heritability of birth weight and weaning weight by half sib correlation method were $0.048{\pm}0.022$ and $0.101{\pm}0.012kg$, respectively. The high heritability estimates of birth weight indicates that selection on the basis of individual's own record will be effective. The low estimates of heritability of weaning weight indicates more emphasis should be given to improve environmental conditions for better achievement.

This study was carried out to investigate the analgesic and antipyretic effects of acupuncture in goat suffered from pain and fever induced experimentally : electroacupuncture and laser acupuncture for the relief of pain and traditional needing for the of fever. Pain was induced by intraperitoneal injection of 0.7% acetic acid solution and it's extent was estimated with the number of writhing syndrom as indicator of pain. When lipopolysaccharide was given into the vein in goat, fever with biphasic type was produced. In the goats with pain the superior analgesic effects of electroacupuncture to aminopyrine and sulpyrine were found, but the effects of laser acupuncture were not satisfactory. The high body temperature of goats was gradually decreased with the lapse of time following traditional needling(venesection by needle) and showed a tendency to return to normal body temperature. Serum GOT, GPT:, BUN, creatinine values and acetylcholinesterase activity following electroacupuncture were not altered. It is considered that electroacupuncture combined with medicament can sucure exellent analgesic and antipyretic effects in animal practice.

The effect of yohimbine HCI(0.25mg / kg) on xylazine(0.15mg /kg) induced depression of rumen motility was investigated by means of electromyography of luminal wall in korean native goats. Yohimbine was administrated 5 min pre-xylazine injection, 5 min and 15 min after xylazine injection. The duration of lumen motility in cases of xylazine alone administration, yohimbine administration 5 min pre-xylazine injection, 5 min post-xylazine, and 15 min post-xylazine was 47-64, 36-40, 28-29, and 15-17 min, respectively. It is demonstrated that lumen contractions were inhibited by xylazine and the inhibition was most rapidly reversed by the administration of yohimbine 15 min after xylazine injection in which goat was completely sedated.

In order to detect the influence of overdosed combelen on the Korean native goats, 5mg of combelen per kg of body weight were injected intramusculary. Clinical findings, electrocardiograms and some blood chemical values were determined and the results obtained were as follows: 1. After administration of 5 mg/kg dose of combelen the animals were moderately depressed and often tried to take sitting position but showed moderate response to pinching stimulation of skin. 2. Body temperature and respiratory rate were not suppressed but heart rate were accelerated during sedative stage. 3. During sedation a slight change in the QRS complex and T wave appeared but it was not significant. 4. Hemoglobin concentration showed a tendency to decrease. SGOT activities were markedly increased 24 hours after administration of combelen and BUN values were slightly lowered. Blood sugar values were markedly elevated during sedative stage.

The development of esophagus in fetuses between 60, 90, 120 days of gestation and neonates of Korean native goats was investigated by light, scanning electron microscopy. The results were summarized as follows; 1. The esophageal wall appeared to be differentiated into the epithelium, lamina propria, tunica muscularis and tunica adventitia at 60 days of gestation. The esophageal epithelium was stratified cuboidal at 60 days, being transformed into stratified squamous epithelium at 90 days, and completely transformed into squamous epithelium an 120 days. 2. In scanning electron microscopy, the longitudinal furrows and ridges appeared on the epithelium of the esophagus of the fetuses at 60 days of gestation. The longitudinal furrow became deeper and microplicae appeared in 90-day-old fetuses. The transverse and longitudinal folds appeared on the epithelial surface of esophagus and the esophageal epithelium started to be keratinized in the neonates.

A total of 77 Black Bengal goats (67 females and 10 males) of 3.5 to 5.0 years old between 18 and 20 kg liveweights were used in this study. The whole liver with gall-bladder from respective carcass was collected at slaughter following fecal and postmortem examinations. Tissue sections of all lobes of each liver were prepared and stained with hematoxylin and eosin following a standard procedure. Results confirmed the presence of flukes surrounded by fibrous capsule in the liver. All the animals were suffering from chronic Fasciola gigantica infections. The blood vessels in most of the liver tissue were thickened due to proliferation of fibrous tissue around them. Focal infiltration of lymphocytes in the lobules, patches of focal accumulation of neutrophils and eosinophils were found in all the liver tissue. Proliferations of new bile ductules in the hepatic trinity around the bile ducts that were clogged by the flukes were also observed in most tissue sections.

The prevalence of warbles (Przhevalskiana silenus Brauer) and efficacy of ivomec against naturally occurring warble infestation in goats in Pothowar area of Pakistan was investigated. About 58.4% of the examined goats (total 301), were infedted by the warbles. The number of warbles per animal ranged from 1 to 23 (mean 5.1). Ivomec (ivermectin 1% w/v, Merck Sharp and Dhome, Netherlands) at the dose of 1 ml/50 kg of body weight proved excellent against this pest. The larvae of all the stages died inside the warbles after treatment and no skin perforations were observed in the treated animals. No side-effects of the drug were observed in the treated animals, except 2-3 minutes of bleating in a few animals at the time of injection.

This experiment was performed to investigate the electrocardiographic changes in experimentally induced hypocalcemia and hypercalcemia in Korean black goats by dosing with 5% disodiumethylene diamine tetraacetic acid at 0.07$m\ell$/kg body weight/min and 10% Ca-borog-luconate at 0.075 $m\ell$/kg body weight/min, respectively. the result were summarized as follows： Heart rate, S-T segment and Q-Tc interval at 3.23 ${\pm}$ 0.10mEq/L plasma calcium level(hypocalcemia) were increased to 100${\pm}$10.5 rate/min, 132 ${\pm}$10msec and 510${\pm}$40msec, respectively. Heart rate, S-T segment and Q-T interval at 6.89${\pm}$0.23mEq/L plasma calcium level(hypercalcemia) were decreased to 73.2${\pm}$5.16 rate/min, 87${\pm}$10msec and 372${\pm}$30msec, respectively. The degree of changes of the heart rate, S-T segment and Q-Tc interval at low plasma calcium level was higher than those at high plasma calcium level.

Pathological studies on 6 milk goats administrated with urea were carried out to determine the effects of acute and chronic poisonings on the animal. Clinical signs appeared about 10 minutes after ingestion of the urea and they consisted chiefly in dullness, staggering, uncontrolled urination, dyspnea, frothy salivation, bloating, muscular tremor, humping of back and tetanic spasms. Macroscopic lesions were failure of blood clot, frothy and bloody contents in the highly congested respiratory tract, pulmonary edema, rumenitis and abomatitis accompanying with petechiation of the upper small intestine. Microscopically, the liver showed vacuolar degeneration, fatty change and areas of necrosis and partial proliferation of the interlobular connective tissues in chronic crises. The renal epithelium displaced vacuolar degeneration, necrosis and hyaline casts in their lumens. In the lungs, there were hyperemia, edema, hemorrhages, and acute catarrhal bronchitis. Neuronal degeneration and necrosis in the central nervous system, catarrhal rumenitis, abomatitis, doudenitis and myocardial hemorrhage were also demonstrated.
