Dystocia, a challenging condition in obstetrics, can arise from various causes, including fetal monsters with structural abnormalities. This case report presents a unique case of dystocia due to a fetal monster known as Perosomus Elumbis in a beetal breed goat from Pakistan. The 4-years-old pregnant doe presented with prolonged straining and failure to deliver the fetus after 8 hours of labor. Upon examination, the cervix was dilated, and only the forelimbs of the fetus were visible in the birth canal. The subsequent delivery involved the application of manual traction by using a dystocia kit, and the removal of edematous fluid from the legs. The monster fetus exhibited absence of hair growth, along with the absence of thoracic vertebrae. Two other fetuses were present, with one found dead and the other alive. Posttreatment involved fluid therapy, antibiotics, and supportive care for the doe. This case report sheds light on the occurrence of Perosomus Elumbis fetal monsters and their impact on dystocia in goat breeding. Understanding the underlying causes and implementing appropriate management strategies are crucial for successful outcomes in similar cases.

This study was conducted to evaluate in vitro antioxidant activity of goat meat hot water extracts and the changes in apoptosis-related protein expression levels in the cancer cells treated with these extracts. Goat meat hot water extracts were prepared using different cuts of goat meat, including foreleg, hindleg, loin, and rib. Among these extracts, the foreleg and hindleg extracts displayed higher (P<0.05) ABTS radical scavenging activity than the other two extracts. Protein expression levels of BAX, p53, and p21 were not different in the cells treated with the extracts from different cuts, regardless of the cell type. Only p53 expression in HT-29 cells was elevated (P<0.05) after loin extract treatment. These results suggest that antioxidant activity and apoptosis-related effects of goat meat hot water extract varied with cut of meat under in vitro conditions. Because all data was obtained from the in vitro experiment, the ability to generalize conclusions is limited. Additional in vivo studies are necessary.

This study aimed to investigate the effects of Centella asiatica powder on the quality characteristics and storage stability of goat meat Tteokgalbi. The goat meat Tteokgalbi samples were prepared with four different quantities (0, 0.5, 1, and 1.5%) of Centella asiatica powder. The moisture content of the samples containing Centella asiatica powder was significantly lower than that of the control (p<0.05). The protein content of the samples containing Centella asiatica powder was significantly higher than that of the control (p<0.05). As the proportion of Centella asiatica powder increased, the pH, L*, and a* values of the uncooked and cooked samples decreased (p<0.05). The water holding capacity and the cooking yield of the uncooked and cooked samples were higher in the samples containing Centella asiatica powder than in the control (p<0.05). Also, with the increasing amounts of the Centella asiatica powder, the thiobarbituric acid reactive substance (TBARS) levels decreased. The 1-1.5% Centella asiatica powder group showed lower levels of volatile basic nitrogen (VBN) than the other groups as per the assay (p<0.05). The results indicate that Centella asiatica powder could enhance the quality characteristics and storage stability of goat meat Tteokgabi.

Corynebacterium pseudotuberculosis is the causative agent of caseous lymphadenitis (CLA), a chronic contagious disease in small ruminants. The prevalence of CLA has been reported to be >50% in Korean black goats. CLA is difficult to control due to a lack of efficient vaccines and treatment methods. Effective disinfection of the farm environment may be an alternative strategy for reducing the spread of C. pseudotuberculosis. The objective of this study was to evaluate the efficacy of commercial disinfectants against CLA. The six commercial disinfectants, largely composed of sodium dichloroisocyanurate, sodium hypochlorite, potassium monopersulfate triple salt, quaternary ammonium, citric acid, and copper sulfate, were tested against five different genotypes of C. pseudotuberculosis isolated from goat farms in Korea. Efficacy tests were performed in accordance with the disinfectant efficacy test guidelines recommended by the Animal and Plant Quarantine Agency of Korea with slight modifications. All disinfectants except for copper sulfate exhibited >99.99% killing efficacy under hard water conditions following 30 min of incubation, which is the recommended standard treatment time according to guidelines. The minimum bactericidal treatment time was evaluated by employing treatments for durations of 1, 5, and 15 min. The most effective compounds under hard water conditions were sodium dichloroisocyanurate, potassium monopersulfate triple salt, and sodium hypochlorite, exhibiting >99.99% killing efficacy after 1 min of treatment. In the aqueous solution forms, citric acid and the quaternary ammonium compound were the most effective, but required at least 5 min to kill >99.99% of the bacteria. The current study characterizes the killing efficacy of six commercial disinfectant active compounds against C. pseudotuberculosis. Thus, this study provides essential information regarding the efficacy of the disinfectants used to control CLA in goat farms.

The nutrient balances originated from livestock manure in Korea has not being include minor livestock species (e.g., horse, deer, and goat) since their manure excretion unit (MEU), nutrient excretion unit (NEU), and nutrient loading coefficient (NLC) are not known yet. In the present research work, the primary focus had laid therefore on securing domestic MEU for the specified minor livestock species which provides the basis for the computation of NEU and NLC. Moreover, the nutrient potential and economic value of composted manure from minor livestock was assessed on the basis of contents in the inorganic fertilizers such as Urea, (46% N) and Fused superphosphate (20% phosphorus pentoxide). The obtained MEU was found to be 10.52±5.48, 4.07±1.69, and 0.843±0.1 kg/head/day for horse, deer, and goat, respectively. In addition, the measured NLCs of horse, deer, and goat were [N, 0.7; P, 0.9], [N, 0.7; P, 0.6] (Both deer and goat were the same.), respectively. Consequently, the horse, deer, and goat manure have a potential of 3,840.1 ton N/year and 9,390.2 ton P/year as an inorganic fertilizer of urea and fused superphosphate. These findings may facilitate the development of more accurate nutrient budget taking into account both major and minor livestock and improve the manure management measures for land application.

This study investigated the quality characteristics of dry-fermented sausage using goat meat and evaluated its applicability. For this, the samples were prepared by dry-fermenting a control (100% pork) and two treatments (50% goat meat replacement or 100% goat meat replacement) for 21days. The moisture content, ㏗ and water activity were decreased in all treatments whereas lactic acid bacteria (LAB), texture profile analysis (TPA) and volatile compounds were increased during dry fermentation periods. In comparison of treatments, the dry-fermented sausage showed no significant difference in proximate compositions, yield, ㏗, water activity, LAB and TPA compared to the control (P>0.05). However, sausages with goat meat also had significantly higher values of C14:1, C18:1t and C18:3 than the control (P<0.05). Analysis of volatile compounds showed increased level of hexanal, octanal and 1-hexanol as replacing pork by goat meat in dry-fermented sausages (P<0.05). Goat meat replacement increased flavor intensity of dry-fermented sausages, but no difference was observed in overall acceptability score of the control and treated samples (P>0.05). Therefore, goat meat could be useful on raw material in dry-fermented sausage as well as pork.

In this study, the effect of forage sources in the total mixed ration (TMR) on in vitro goat rumen fermentation was investigated. Rice straw (RS), Italian ryegrass (IRG), timothy (TIM), and alfalfa (ALF) were used as forage sources. Each forage source was mixed with a commercial goat concentrate diet in the ratio of 1:1. Total 4 TMR were prepared. Rumen simulated in vitro fermentation using goat rumen fluid collected from the slaughterhouse was conducted until 72 th . For fermentation parameters, gas production (GP), volatile fatty acids (VFAs), and ammonia nitrogen (NH3-N) were examined. All assays were performed at 24 th , 48 th , and 72 th h of incubation individually. Contents of crude protein and non-fibrous carbohydrate were greater in the order of RS < IRG < TIM < ALF. Significant treatment effects were found in valerate and NH3-N at 24 th h of incubation (p<0.05). ALF showed the greatest contents of them and RS was the lowest. At 48 th incubation, a significant effect was detected at GP (p<0.05) and RS was greater than others. However, GP of RS was lower than others at 72 th . Significant effects on Total VFA, butyrate, and valerate productions were found at 72 th h of incubation (p<0.05). ALF showed the greatest production. Methane production from all treatments was not significantly different for each incubation time (p>0.05). The present study provided primary information on how goat rumen fermentation responds to different nutrient contents and forage sources of TMR. And the information could be used for the design or optimizing economical diet formulation for goats.

This study was conducted to evaluate the forage productivity and feed value of Sasa borealis (S. borealis) using growing black goats(S. borealis) in order to improve the utilization of S. borealis and to help mitigate the problem of reduced plant species diversity caused by S. borealis in Hanlla Mountain. One control and three treatments were made by the level of addition of S. borealis silage to the TMR feed. T1(10%), T2(20%), and T3(30%) treatments showed more daily weight gains than control group. Feed conversion ratio of T2 is 4.4g, which is significantly lower than control(P<0.05). The nitrogen retention in the control, which had relatively high dry matter intake, was 12.5g, which was significantly higher than that of T3. Sasa. borealis silage is considered to be able to use as a forage source for black goats, and if it is fed in an appropriate amount, it is considered that it will help improve livestock productivity, such as weight gain and feed conversion ratio.

The present study was conducted in a goat farm for pregnancy diagnosis by using vaginal cytology and B-mode real time ultrasound using 5 MHz probe by transabdominal method. Seventeen pregnant does were used for this study. The objective of the study was to determine the earliest day of pregnancy and describe the chronological characteristics of pregnancy from day 22 to day 40 for vaginal cytology and day 25 to day 60 for ultrasonography of gestation. The differences among the average percentage of cell value in different age of pregnancy were significant (p < 0.05). The average percentage of intermediate cells (81.12%) was also significantly (p < 0.05) higher than superficial (9.41%), keratinized (7.10%) and neutrophil (2.61%) on 22-40th days of pregnancy. In case of real time B-mode ultrasonography, the gestational sac was observed only in three does out of seventeen (17.6 %) at 25-30 days whereas the placentomes and heart beat of the foetus were first detected at 31-35 days in six does (35.3%). The foetal leg buds were first visualized at 36-40 days in four does (23.5%) whereas the foetal vertebral column was first observed at 36-40 days of gestation in only three does (17.6%). In conclusion, vaginal cytology and trans-abdominal ultrasonography can be used for detection of early pregnancy in does.

We report a massive outbreak of human Q fever cases, which occurred at totally 11 humans. The occurrence was related to a goat farm where Coxiella burnetii infection was diagnosed from goat tissues and environmental specimens. From January of 2018, continuous abortions from 6 goats occurred. Laboratory tests from 77 goat specimens for C. burnetii showed that 54 (70.1%) and 63 (81.8%) goats were positive by polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA), respectively. The infection was also confirmed from the farmer, his wife and 9 persons from all 16 veterinary officials who had visited the farm for protective measures and preparing goat specimens for laboratory tests. The farm was found to be extensively contaminated with C. burnetii from the examination to the environmental specimens and epidemiological inspections, which might be the main source of C. burnetii infection to humans. The extensive contamination to the farm was derived from the uncareful handling of postpartum animal tissues or discharges by the farm owner. This report will contribute to the establishment of educational system on the biosecurity to novice farmers.

The present study aimed to investigate the conceptus-related changes during early pregnancy in the Black Bengal breed of goat. A total of 22 gravid genitalia of the Black Bengal goats were collected from local slaughterhouses. The crown-rump lengths (CRL) of the conceptuses were determined to estimate the gestational age (GA). The length and diameter of uterine horn and amniotic sac were measured, and volume of amniotic and allantoic fluid formed by individual conceptus were recorded. The results reveal that the CRL is positively correlated with GA of the conceptus (R2 = 0.89, p < 0.05); however, CRL was not influenced by number of conceptus. Both the left and the right uterine horn gradually increased in size with the advancement of pregnancy irrespective of conceptus number present in the horn. The size of the amniotic sac of conceptus gradually increased with the conceptus age but maintained spherical shape from 5 to 7 weeks of pregnancy. The amniotic fluid formed by individual conceptus rapidly increased from 5 weeks (3.4 ± 0.3 mL) to 7 weeks (21.0 ± 2.0 mL) and 9 weeks (111.5 ± 4.0 mL). The volume of allantoic fluid formed by individual conceptus was steadily increased until 7 weeks (60.0 ± 5.0 mL) and began to decline slowly thereafter (50.0 ± 5.0 mL at 9 weeks). Notably, there was no effect of conceptus number per pregnancy on individual amniotic and allantoic fluid volume. The cotyledons have first appeared on the allanto-chorionic surface from 4 to 5 weeks of pregnancy. The closed eye, nostril and hooves of the conceptus became visible at 7 weeks of pregnancy. The present study has shown the basic information on conceptus-related developmental changes during early pregnancy up to 9 weeks in Black Bengal goat.

본 연구에 이용되는 국내 재래 흑염소는 유전적 자원을 보존하고 품종을 유지하기 위하여 소규모 집단에서 고도의 근친교배를 수행하고 있어 유전적 자질의 다양성이 저해되고 있을 것으로 우려되었다. 따라서 본 연구는 국내 재래흑염소 경상대계통 집단의 유전체 정보를 활용하여 재래흑염소 집단의 유전적 특성과 유효집단의 크기를 추정하고자 실시하였다. 국내 재래 흑염소의 유전체 정보는 Illumina Goat SNP 50k chip (illumina, inc., San Diego, CA)의 정보를 분석하여 연구에 이용하였다. 각 염색체의 인접 표지인자 와의 연관불평형 (Linkage Disequilibrium)은 0.225로 추정이 되었다. 또한, 표지인자 사이의 거리가 증가함에 따라 연관불평형의 값은 감소되는 것으로 나타났다. 국내 재래 흑염소의 유효집단크기는 최근의 세대로 오는 경우 감소하는 추세를 보였으며, 13세대에서 유효집단의 크기는 29두로 추정되었다. 재래 흑염소 경상대계통은 낮은 연관불평형 값과 유효집단 크기를 보여 유전적 자원의 다양성이 낮을 것으로 보이며, 이를 해결하기 위한 계획적인 교배와 품종 집단의 크기를 키우기 위한 대책이 필요할 것으로 사료된다.

Mesenchymal stem cells (MSCs) are multipotent cells capable of replicating as undifferentiated cells, and have the potential of differentiating into mesodermal lineages. Goats are commonly used as animal models for bone tissue engineering to test the potential of stem cells for bone regeneration. Goat MSCs isolated from bone marrow (BM) or adipose tissue (AD) should be evaluated using in vitro assays, prior to their application in a tissue engineering project. In this study, we compared the stem cell properties of MSCs derived from goat AD, BM and ear skin tissue (ESK). As results, BM and ESK-MSCs exhibited a spindle-shaped morphology comparable to that of AD-MSCs. Especially, BM-MSCs could be cultured for significantly longer periods and exhibited the greatest expansion capacity, whereas AD-MSCs had the shortest culture time and lowest growth rate. Also, we compared differentiation potentials of AD, BM and ESK-MSCs into adipogenic, chondrogenic, and osteogenic lineages through specific staining and quantitative real-time RT-PCR. Collectively, we successfully isolated ESK-MSCs from goat for the first time. This study suggests that adult skin tissue of goat could be used as a source of goat MSCs. Further studies are needed to show the more information for establishment and fully characterization of goat ESK-MSCs.

The aim of this study was to assess the levels of genetic diversity and relationships of Korean native black goat (n = 58), compared with the exotic breed, Boer (n = 97). For the analysis of genetic characterization 11 microsatellite markers (MAF065, INRA063, CSRD247, OarFCB20, SRCRSP5, INRA006, ILSTS008, ILSTS011, INRA005, ILSTS087, SRCRSP8) were genotyped. The number of alleles was observed 3 (INRA005) to 10 (SRCRSP8) each markers. The mean expected and observed heterozygosity (Hexp and Hobs) and polymorphism information content (PIC) for the Korean native black goat breed varied from 0.551 to 0.860, 0.517 to 0.948 and 0.464 to 0.835, respectively. Principal Components Analysis (PCoA) and FCA results showed that Korean native black goat breed was confirmed to be clearly separated from bore breed. These results were scientific evidence that Korean native black goat represents a unique and valuable animal genetic resource.

A case of caseous lymphadenitis (CL) was detected in a native Korean goat without manifestation of superficial nodules but with pulmonary abscesses that were characterized microscopically by granulomatous inflammation consisting of a central necrotic region, peripheral fibrous capsule, and numerous cellular infiltrates with epithelioid macrophages, giant cells, and lymphocytes. Presence of Corynebacterium pseudotuberculosis was identified by using bacterial isolation and multiplex PCR. In addition, a 43% seropositivity to C. pseudotuberculosis was observed in goats from the same farm. This case highlights the risk of exposure of farmers to the causative agent and the urgent need for national monitoring for CL, a potential zoonotic.
