Serum enzyme activities of sorbitol dehydrogenase, glutamate dehydrogenase, gamma glutamyltransferase, alkaline phosphatase, aspartic aminotransferase, and creatine kinase, were measured in five clinically normal mixed-breed goats. Tissue activities of these enzymes were also measured in two goats. These basal serum values were then used to determine the response to treatment with carbon tetrachloride (CCl4). The basal value for serum and hepatic tissue sorbitol dehydrogenase were appreciably greater for goats than previously reported for sheep and cattle. The change in the above serum enzymes after CCl4 treatment resembled that in sheep, but the amount of sorbitol dehydrogenase increase was less than that in sheep. This study established basal tissue and serum enzyme activity values and demonstrated the efficacy of the use of changes in serum S.D.H. and G.D.H. activity as indicators of acute hepatopathy in goats.  相似文献

Blood serum of pygmy goats (both sexes, and castrated males) was analyzed to establish biochemical reference values. Influence of age on reference values was also studied. Serum biochemical analyses were made for urea nitrogen, creatinin, bilirubin, lactate dehydrogenase, aspartate aminotransferase, alkaline phosphatase, glucose, uric acid, and total lipids. These serum values for pygmy goats were similar to those reported for man, except as follows: Aspartate aminotransferase activities were slightly higher than those reported for man. Glucose concentrations in pygmy goats were slightly lower than in human beings, and uric acid levels were significantly lower than the values for man. Female and castrated male goats had lower total lipid concentrations than did human beings, whereas intact males had higher concentrations. Thus, of the 9 measured variables for pygmy goats, 5 were comparable to human values. This, together with other attributes, including the small size which conduces to economics of maintenance and enhances the desirability of using pygmy goats in research.  相似文献

The clinical pathology of Schistosoma curassoni infection in sheep and goats was studied for 22 weeks following experimental infection with 7000 and 4000 cercariae, respectively. Excretion of eggs began at week 7 after infection: in goats the numbers increased to 30 to 50 eggs per gram faeces (epg) at weeks 8 to 18, followed by a reduction. In a pregnant goat, epg values increased markedly before and after parturition. The mean faecal egg counts in sheep were lower than in goats, increasing to a maximum level of 30 epg at weeks 16 and 17 after infection. Infected sheep maintained growth rates roughly comparable with controls, whereas infected goats failed to gain as much weight as the controls. Infected goats and sheep produced eosinophil counts of about 3 x 10(3) mm-3, five and eight weeks after infection, respectively. Sheep developed a progressive anaemia from week 11 after infection, in goats blood values remained within normal limits. Differences in serum protein concentration were observed between infected and uninfected goats about nine weeks after infection, but not in sheep. Increased total protein values, hyperglobulinaemia and lowered albumin to globulin ratios were features of infected goats. Serum glutamate oxaloacetate transaminase, glutamate pyruvate transaminase, gamma-glutamyl transferase, total lactate dehydrogenase and bilirubin were not significantly changed. The mean recovery in sheep was 608 worms, in goats 428 worms, but the total tissue egg counts were higher in the latter. Of the total eggs deposited in the goats 92 per cent were found in the liver with 51.5 per cent in the ovine liver. The histopathological changes were studied.  相似文献

OBJECTIVE: To determine hepatic effects of halothane and isoflurane anesthesia in young healthy goats. DESIGN: Randomized prospective clinical trial. ANIMALS: 24 healthy 9-month-old female goats. PROCEDURE: Goats were sedated with xylazine hydrochloride and ketamine hydrochloride and anesthetized with halothane (n = 12) or isoflurane (12) while undergoing tendon surgery. End-tidal halothane and isoflurane concentrations were maintained at 0.9 and 1.2 times the minimal alveolar concentrations, respectively, and ventilation was controlled. Venous blood samples were collected approximately 15 minutes after xylazine was administered and 24 and 48 hours after anesthesia, and serum aspartate aminotransferase (AST), sorbitol dehydrogenase (SDH), alkaline phosphatase (ALP), and gamma-glutamyltransferase (GGT) activities and bilirubin concentration were measured. Goats were euthanatized 25 or 62 days after anesthesia, and postmortem liver specimens were submitted for histologic examination. RESULTS: All goats recovered from anesthesia and survived until euthanasia. Serum SDH, GGT, and ALP activities and bilirubin concentration did not increase after anesthesia, but serum AST activity was significantly increased. However, serum hepatic enzyme activities were within reference limits at all times in all except 1 goat in which serum AST activity was high 24 and 48 hours after anesthesia. This goat had been anesthetized with halothane and had the longest duration of anesthesia. No clinically important abnormalities were seen on histologic examination of liver specimens. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that use of halothane or isoflurane for anesthesia in young healthy goats is unlikely to cause hepatic injury.  相似文献

Three goats were dosed orally with a 0.2 % aqueous copper sulphate solution. The dosing was 20 mg copper sulphate/kg body weight twice a day for 56 to 113 days. One of the goats accumulated substantial amounts of copper in the liver and developed two haemolytic crises. The two other goats showed only increased liver copper concentrations before they were killed. The results indicate that the goats were susceptible in varying degrees to repeated oral copper dosing, and that two of the goats were significantly less susceptible to copper than sheep. The goat that turned into a haemolytic crisis showed changes similar to those seen in sheep as far as blood and plasma parameters are concerned. The gross and histological lesions were also mainly of the same type as described in sheep. The hepatic lesions found in the goat differed to some degree from those found in sheep as the necroses were more distinctly located to the centrilobular area, and as the iron pigments were mainly located in phagocytes in the hepatic sinusóides.  相似文献

Goats previously infected with 100 viable Fasciola gigantica metacercariae and treated with rafoxanide (Ranide, 7.5 mg/kg) at week 4 were not protected against subsequent homologous challenge with 250 metacercariae administered two weeks later. Reinfection resulted in more severe hepatic lesions and a higher percentage of flukes recovered as compared with primarily infected controls. However, the size of flukes originating from the second (challenge) infection was considerably reduced. The plasma enzyme activity of aspartate amino-transferase (AST), glutamate dehydrogenase (GD) and sorbitol dehydrogenase (SD) increased to a similar extent with primary and challenge infections. However, the plasma antibody response to F. gigantica was less pronounced in reinfected goats.  相似文献

Hepatic necrosis following halothane anesthesia in goats   总被引:2,自引:0,他引:2  
One goat anesthetized with thiamylal sodium, xylazine, and halothane for repair of an abominal hernia, and 7 of 29 goats similarly anesthetized for an experiment unrelated to considerations of anesthesia, developed signs of hepatic failure within 24 hours of anesthesia. Affected goats had high values for serum aspartate transaminase and serum total bilirubin by 12 to 24 hours after induction of anesthesia. Necropsy of the 8 affected goats revealed centrilobular to massive hepatic necrosis (8 of 8), brain lesions consistent with hepatic encephalopathy (3 of 4), and acute renal tubular necrosis (6 of 6). Two unaffected goats had no hepatic necrosis. Causes of hepatic necrosis other than those related to anesthesia (eg, infectious agents, toxins) were ruled out by lack of supporting necropsy findings or were considered unlikely because of lack of opportunity for exposure. Hepatic lesions in these goats closely resembled those described in human beings with halothane-associated hepatic injury, although in both species these lesions are nonspecific at the gross and light microscopic levels. The pathogenesis of halothane-associated hepatic injury in goats, as in human beings, remains to be determined.  相似文献

The features of naturally occurring Yersinia pseudotuberculosis serotype III infections in 16 sheep, one goat and 3 pigs, and Y. pseudotuberculosis serotype I infections in 3 goats, are described. Affected animals usually had diarrhoea and were in poor condition or emaciated. A number were moribund or dead when submitted for necropsy. Thickening of the caecal and colonic mucosa was the only gross lesion attributable to Y. pseudotuberculosis infection, with liver or other visceral abscesses not being seen. Characteristic microabscesses were demonstrated in the intestinal mucosa of 10 sheep, one goat and one pig infected with Y. pseudotuberculosis serotype III and one goat infected with Y. pseudotuberculosis serotype I. Sheep, goats and pigs dosed orally with Y. pseudotuberculosis serotype III, the serotype isolated most commonly from these species, developed intestinal infection. In sheep and pigs, infection was accompanied by diarrhoea. Haematological changes and specific antibodies were elicited in all 3 species in response to infection. Microabscesses were seen in the intestinal mucosa of all experimentally exposed animals. The occurrence of field cases and the results of experimental exposure confirm that Y. pseudotuberculosis serotype III is an enteropathogen of sheep, goats and pigs. The association of Y. pseudotuberculosis serotype I with lesions in a goat, indicates that this bacterium may also be a pathogen of this species. It is concluded that Y. pseudotuberculosis serotype III is an enteric pathogen of a wide range of ungulate species including cattle, buffalo, deer, antelopes, sheep, goats and pigs. Serotypes I and II, while having a more restricted host range, are probably also pathogens of ungulates and, in particular, deer, antelopes and goats.  相似文献

Seventy-three, 10-week-old, newly weaned Omani goats of three different breeds, namely Dhofari (D), Batinah (B) and Jebel Akhdar (JA) were randomly divided into a control (n=38) and a treated group (n=35) for an experimental period of 10 months. Goats in both groups were fed 150 g/day per head of a pelleted concentrate, based on body weight and their requirements and Rhodes grass hay ad libitum, containing 0.12 and 0.10 mg/kg DM cobalt, respectively. Goats in the treated group also received bi-monthly subcutaneous injections of 2000 microg hydroxycobalamin. In contrast to the treated goats, the control animals of all breeds experienced a severe decrease in their serum vitamin B(12) levels, developed pale mucous membranes, appeared scruffy and two breeds (D and B) had significantly lower weight gains from month 5. Untreated kids of all breeds had significant decreases in their red blood cell counts and erythrocyte indices after approximately four months. Controls developed low total serum protein levels whilst activities of alkaline phosphatase and aspartate aminotransferase significantly increased. Although it is widely assumed that goats are more resistant to cobalt deficiency than sheep this is apparently not true for Omani goats. Based on experimental data from previously reported studies and those from the present study it can be concluded that the reduction in weight gains in D and B goats is related to their lower digestibility coefficients for dry matter, crude protein and energy while the increase in alkaline phosphatase and aspartate aminotransferase are associated with developing hepatic lipidosis.  相似文献

Serum enzymes were studied in 163 apparently healthy goats from three indigenous goat breeds of Ethiopia. The effect of breed, age, sex and season on alanine aminotransferase (ALT) / glutamic pyruvic transaminase (GPT), aspartate aminotransferase (AST) / glutamic oxalacetic transaminases (GOT), alkaline phosphatase (ALP) and acid phosphatase (AcP) levels was assessed. The mean serum enzymes levels of the indigenous Arsi-Bale, Central Highland and Long-eared Somali goat breeds ranged from 14.0–20.2 iu L−1 for ALT/GPT, from 43.2–49.3 iu L−1 for AST/GOT, from 83.7–98.8 iu L−1 for ALP, and from 2.99–4.23 iu L−1 for AcP, were within the normal range for goats elsewhere. Breed had significant influence on AST/GOT values. Sex had significant effect on ALT/GPT for Arsi-Bale goats with higher values in males than females. Age was significant on all serum enzymes studied in the Arsi-Bale goats and on ALP in the Central Highland goats. Season had significant influence on all serum enzymes except for ALT/GPT in the Arsi-Bale goats. The serum enzyme levels of these indigenous goat breeds can be used as normal reference values for Ethiopian goat breeds adapted to similar agro-ecology and production system.  相似文献

Severe persistent orf in young goats.   总被引:1,自引:0,他引:1  
Orf (contagious ecthyma) is a viral disease of small and wild ruminants, humans, and less frequently other species. In sheep and goats, the disease is characterized by the formation of vesiculo-proliferative lesions in the skin of lips and nostril. Here, a form of generalized orf in 16 goat kids from 2 different locations in west Texas is described. The disease was characterized by multifocal, severe, proliferative dermatitis that persisted from about 2 months of age until the goat kids were euthanized 3 months later. All affected goats were Boer or Boer crosses under 1 year of age. The mean immunoglobulin concentration in sera of affected goats was elevated compared with healthy control goats. Severe to moderate lymphadenomegaly of the nodes draining the areas of the skin affected with orf lesions was present in all 16 goat kids. Suppurative arthritis, chronic fibrinous pneumonia, and premature thymic involution were found in 3, 5, and 7 of the goat kids, respectively. The skin lesions of 3 goat kids were infested with larvae of the opportunistic black garbage fly (Ophira sp.). The orf virus was identified in skin lesions by isolation in Marbin-Darby ovine kidney cells, electron microscopy, and amplification of viral DNA by polymerase chain reaction. The orf virus was not detected in peripheral blood or lymph node mononuclear cells of any of the goats. Cross-neutralization experiments showed that an ovine orf virus antiserum raised in sheep was more effective in neutralizing a sheep orf virus isolate than a caprine orf virus isolate. The clinical and epidemiological characteristics of these orf cases may be the result of susceptibility factors within some individuals of the Boer breed of goats.  相似文献

Ovine scrapie was first recorded in Cyprus in 1985. Subsequently four dairy goats kept in two mixed flocks with affected sheep developed characteristic clinical signs similar to those seen in sheep. Fifteen goats from the two flocks were examined histologically and neurological lesions consistent with a diagnosis of scrapie were found in the four animals and in three others which had subsequently developed early neurological signs. These lesions were similar to those of naturally-affected sheep although neuronal degeneration and vacuolation were more severe in some cases.  相似文献

Caprine aflatoxicosis: experimental disease and clinical pathologic changes   总被引:3,自引:0,他引:3  
Groups of 8 male crossbreed domestic goats were given 3 dosage levels of aflatoxin B1 [(AFB1) mg/kg of body weight/day] orally: 0.1 for 34 days; 0.2 for 18 days; or 0.4 for 10 days. Clinical condition, feed consumption, and selected blood values were determined. Clinical signs of toxicosis included decreased feed consumption, slight-to-moderate loss of body weight, mucopurulent nasal discharge, dyspnea, coughing, lethargy, icterus, diarrhea (4 goats), and subnormal body temperature 24 to 48 hours before death. Clinicopathologic changes included increases in total RBC count, PCV, hemoglobin concentration, serum bilirubin concentration, and serum activities of aspartate aminotransferase, isocitric dehydrogenase, and ornithine carbamyl transferase. Goats given the 2 smaller dosage levels of AFB1 had slight increases of serum total protein (TP) concentration compared with control goats, but goats given the larger dosage levels of AFB1 initially had a slight decrease in TP. Aflatoxin had little effect on total WBC count. Serum alanine aminotransferase (ALT) activities in goats given the 2 larger dosage levels of AFB1 were similar to those of control goats, but goats given the smallest dosage level of AFB1 had increased serum ALT activities. Aflatoxin did not produce consistent dose-related changes in serum alkaline phosphatase activities. Seemingly, goats are susceptible to aflatoxin. Onset of clinical signs was dose-related. Onset and magnitude of increases in PCV, hemoglobin concentration, serum bilirubin concentration, and activities of serum aspartate aminotransferase, ornithine carbamyl transferase, and isocitric dehydrogenase were dose-related. Changes in TP and activities of serum ALT and alkaline phosphatase were neither dose-related nor were they potentially useful indicators of toxicosis.  相似文献

为从生化特性方面研究该品种的种质特征,文章比较了湖北乌羊与酉州乌羊等其他山羊12项血液生化指标。结果表明,湖北乌羊的血清谷草转氨酶(AST)、胆固醇(TC)、球蛋白(GLOB)和低密度胆固醇(LDL-C)极显著高于其他山羊(P<0.01);过氧化氢脱氢酶(LDH)、白球比(A/G)以及高密度胆固醇(HDL-C)极显著低于其他山羊(P<0.01)。这些差异在一定程度上可能与湖北乌羊比其他山羊具有较强的抗应激能力和抗病性有关,部分差异可能还与其独特的乌质性状有关。  相似文献

Sheep and goats were shown to be susceptible to experimental infection with bovid herpesvirus 2 (BHV2), administered by either the intradermal or intravenous route. Lesions developing in sheep following intradermal inoculation of virus were similar to those in cattle inoculated intradermally, whereas the lesions in goats resolved without ulceration or scabbing. Disseminated circumscribed skin lesions developed in sheep and goats given BHV2 by the intravenous route. These lesions resolved in four to eight days without significant effect on the skin. BHV2 was isolated from skin lesions of sheep, goats and cattle that were infected intravenously, from sheep and cattle infected intradermally and from the leucocytes of the three species following intravenous inoculation of virus. Latent infection of sheep and goats was demonstrated following corticosteroid treatment 60 days after infection.  相似文献

One or two mature primary infections with Fasciola gigantica which had been removed by anthelmintic treatment resulted in a significant reduction in the number of flukes recovered from challenge infection as compared with that from controls.

Characteristic lesions of fascioliasis were seen in the livers of the 3 groups, however, goats with two primary abbreviated infections prior to challenge showed more severe lesions than those of animals with one primary abbreviated infection or those of challenge controls. The former group also showed the highest serum glutamate dehydrogenase and sorbitol dehydrogenase peaks following challenge infections and pulmonary fascioliasis was encountered in one of the goats of this group. Haemoglobin concentration and packed-cell volume decreased after infection in the three groups of goats.  相似文献

Some biochemical indices in naturally occurring fascioliasis in goats   总被引:2,自引:0,他引:2  
Some biochemical indices were assayed in goats naturally harbouring Fasciola gigantica infection and compared with uninfected control goats. Infected goats had significantly lower levels of serum glucose (47.6 +/- 1.8 mg dl-1) and albumin (3.1 +/- 0.1 g dl-1) and reduced albumin:globulin ratio (1.1 +/- 0.1). Total lipid (526.8 +/- 2.4 mg dl-1), serum glutamate dehydrogenase (15.3 +/- 0.9 iu litre-1) and serum alkaline phosphatase (31.6 +/- 1.9 Kind's and King's unit dl-1) were high in infected goats. No significant changes could be recorded in serum total protein, cholesterol and phospholipids.  相似文献

Enterotoxemia was induced in 4 lambs and 4 goat kids by continuous intraduodenal infusion of a whole culture of Clostridium perfringens type D. Clinical signs, hematologic values, biochemical alterations, and postmortem lesions in the lambs and goat kids were compared. The 4 lambs and 4 goat kids died within 25 hours of beginning the infusions. Lesions were not observed in the gastrointestinal tract of the 4 lambs; however, severe hemorrhagic enterocolitis was found in the 4 goat kids. This difference between the lambs and goat kids in the lesions caused by experimentally induced enterotoxemia may explain the discrepancies reported between sheep and goats in clinical signs, response to treatment, and efficacy of vaccination observed in naturally induced enterotoxemia in the 2 species.  相似文献

Results of blood coagulation and hematologic studies on 6 goats, each tested 3 times, were compared to the values seen in persons. Special blood platelet studies were done on an additional goat. Blood coagulation values in the goats and in persons were similar, with these exceptions: In the goat, activated partial thromboplastin time was shorter and thrombin time was longer; one-stage assays of factors V, VIII, and IX were very high, and platelets aggregated poorly epinephrine and ristocetin. Both platelets and erythrocytes were small. On scanning electron microscopy, the erythrocytes appeared as flat disks or triangles, occasionally having a dimpled center, compared to the deeply dimpled doughnut shape of the larger human erythrocytes. Osmotic fragility of these small erythrocytes was greater than that of their human counterparts. By transmission electron microscopy of ultrathin sections of goat buffy coat, platelets had fine structures similar to those of human platelets. Unlike in human platelets, most of the dense bodies in goat platelets were surrounded by clear vacuoles. Biochemical studies showed higher than human levels of phosphorus, chloride, sodium, alkaline phosphatase, and serum glutamic oxaloacetic transaminase.  相似文献
