서울동물원에서 쟈넨 염소가 마콜에 의해 임신이 되었고, 세 마리의 히말라얀타알이 같은 종의 수컷에게 잘못 임신이 되었다. 의도적이던 우발적이던 다른 종간에 번식을 시켜 잡종을 생산하는 것은 종보전의 근본적인 원칙에 위배된다. 2002년 10월에 수입되었으며 염색체수가 염소와 같은 60개를 가진 마콜이 우연히 쟈넨과 교미를 하게 되었다. 사육사들의 기록을 토대로 교미날짜를 추정하였다. 히말라얀타알 3수와 쟈넨은 $PFG_2{\alpha}$ 제재 (dinoprost tromethamine) 15 mg을 근육주사하여 성공적으로 유산을 시켰다.

The aim of the present study was to determine the effect of dietary cultured wild ginseng root (CWGR) supplementation on goat milk composition and ginsenoside profiles. Sixteen Saanen dairy goats were allocated to two balanced groups based on lactation period, body weight ($38.6{\pm}3.2kg$), and dairy milk yield ($2.85{\pm}1.2kg$), and were kept in separate pens. Goats were fed a total mixed ration (TMR) feed (2.3 kg/d, dry matter basis) and 1.5 g of CWGR powder was supplemented in the experimental diet. The total feeding period was 3 weeks, and milk and blood samples were collected on the last three days of the experimental period. There was no effect of CWGR on daily milk yield and milk composition (fat, protein, lactose, and solid-not-fat). However, the CWGR-treatment group had significantly higher plasma IgG and protein contents than the control group (P < 0.05). Significant amounts of ginsenosides were observed in the milk of the CWGR-treatment group, whereas ginsenosides were not detected in the milk of the control group. In conclusion, dietary CWGR was a useful regimen to produce functional goat milk enriched in ginsenosides.

Previously, we observed high level expression of goat β-casein/genomic hGH fusion gene in mammary gland of transgenic mice. To develop an expression vector to make a human granulocyte-colony stimulating factor (hG-CSF) protein efficiently produced in milk of transgenic animals, we designed a new bicistronic vector using the goat β-casein/genomic hGH fusion gene as regulation sequences for expression and internal ribosome entry site (IRES) as a mediator for second gene expression. This vector was constructed by insertion of encephalomyocarditis virus (EMCV) IRES-dependent second gene region coupled with hG-CSF cDNA into 3' untranslated region of an intact hGH gene. By microinjcetion, four transgenic mice were generated and three of them transmitted the bicistronic vector to their progeny. (omitted)

Among the main intimidation to the sheep and goat population, PPR outbreaks are causing huge losses especially in endemic areas. During recent times, six outbreaks of PPR were confirmed at semi-organized goat farms/herds in various regions of Punjab province and Islamabad capital territory (ICT), Pakistan. The disease started after introduction of new animals at these farms with no history of previous PPR vaccination. The clinical signs appeared affecting respiratory and enteric systems and spread quickly. Disease caused mortality of 10-20% and morbidity of 20-40% within a time period of four weeks. Morbidity and mortality rates were 30.38% (86/283) and 15.55% (44/283), respectively. Three treatment regimes were executed to demonstrate the role of vaccination during outbreak at these farms. First was to use only the broad spectrum antibiotics (Penicillin & Streptomycin and/or Trimethoprim and Sulfadiazine) at two farms (Texilla and Attock). Second treatment regime was to use the same broad spectrum antibiotic along with extensive fluid therapy (Farms at ICT-1 and ICT-2). The third regime was to use of broad spectrum antibiotic plus fluid therapy along with vaccinating the herd against PPR during first week of outbreak (ICT-3 and ICT-4). The third scheme of treatment gave the better results as there was no mortality in third week post-outbreak. Therefore, it is suggested to give proper importance to PPR vaccination along with conventional symptomatic treatment when dealing the PPR outbreaks in endemic disease conditions.

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.

Actomyosin and myofibril were extracted from Korean native Goat muscle with the Weber-Edsall solution. ATPase activities and physiochemical properties were measured. The results obtained were as follows; 1) Mg-activitied ATPase activity of actomyosin and myofibrill from Korean native Goat muscle exhibited a common biphasic response, a typical ATPase pattern, that is high at a low ionic strength and low at a high ionic strength. Actomyosin showed high activity than myofibrill. 2) Mg-activited ATPase activity of actomyosin from muscle increased extraction time 24 hours. 3) EDTA-enhanced ATPase activity of actomyosin was greater than myofibrill and low at the low ionic strength, high at the high ionic strength. The difference of the activity were shown great broad pattern at the after 0.3M KCI concentration. 4) Effect of EGTA on-ATPase activity of myofibrill and actomyosin from muscle was measured, the Mg-ATPase activity was markedly depressed. 5) Solubility of actomyosin from muscle began to solubilize at KCI concentration of 0.28M and solubilized completely at the KCI concentration of 0.3M.

Probiotics are live microorganisms that, when administered in adequate amounts, confer health benefits to the host. This study was conducted for the isolation of potential lactic acid bacteria (LAB) with probiotic properties from goat milk and yogurt. Several tests were conducted in vitro using the standard procedures for evaluating the inhibitory spectra of LAB against pathogenic bacteria; tolerance to NaCl, bile salt, and phenol; hemolytic, milk coagulation, and bile salt hydrolase activities; gastrointestinal transit tolerance; adhesion properties; and antibiotic susceptibility. Among 40 LAB strains screened according to culture characteristics, five isolates exhibited antagonistic properties. Three were identified as Pediococcus acidilactici, and two were identified as Enterococcus faecium, exploiting 16S rRNA gene sequencing. All the isolates succeeded in the gastrointestinal transit tolerance assay and successively colonized mucosal epithelial cells. Based on the results of these in vitro assays, both P. acidilactici and E. faecium can be considered as potential probiotic candidates.

This survey was conducted to investigate the infection of caprine arthritis encephalitis virus (CAEV). From April to October 2007, we examined a total of 173 goats in 7 dairy goat-breeding farms located in Na-ju, Hae-nam, Young-am, and Young-gwang area of Jeonnam province. The results show that 41 (23.7%) goats are positive for CAEV, confirmed by nested PCR of 173 blood samples. Regional analysis revealed that a positive proportion for CAEV was 50.0% in Young-gwang, 25.6% in Young-am, 25.0% in Hae-nam, and 10.9% in Na-ju. Clinical signs were observed in 17 (9.8%) goats, of which 6 suffered from arthritis, 7 from mastitis, and 4 from pneumonia. Among the examined 173 goats, 8(4.6%) goats are positive for CAEV accompanied with CAE symptoms. There was a tendency to be much higher(p<0.05) levels of natrium(Na), chlorine(Cl) in CAEV-positive than in CAEV-negative goats. However, other serum biochemical values were no statistically significant effect.

The rumen parasite, Gastrothylax crumenifer (Platyhelminthes: Gastrothylacidae), is a highly pathogenic trematode parasite of goat (Capra hircus). It sucks blood that causes acute disease like anemia, and severe economic losses occur due to morbidity and mortality of the ruminant infected by these worms. The study of these rumen paramphistomes, their infection, and public health importance remains unclear in India especially in the western part of state Uttar Pradesh (U.P.), Meerut, India, where the goat meat consumption is very high. This paper provides the molecular characterization of G. crumenifer recovered from the rumen of Capra hircus from Meerut, U.P., India by the partial sequence of 28S rDNA. Nucleotide sequence similarity searching on BLAST of 28S rDNA from parasites showed the highest identity with those of G. crumenifer from the same host Capra hircus. This is the first report of molecular identification of G. crumenifer from this part of India.

The ovarian follicular fluid was found to contain steroidogenesis stimulatory protein similar to albumin from human and buffalo. Therefore, the albumins from various species, commercial and purified, were studied for their steroidogenic effect on progesterone secretion by granulosa cells from buffalo ovaries, during culture. A dose of $20{\mu}g$ of bovine serum albumin was optimum to exhibit maximum progesterone secretion on day 6 of culture, in medium ($350{\mu}l$) containing $10^5$ cells. Among commercial albumins, chicken albumin showed highest effect on progesterone secretion, which was followed by albumins from goat, bovine, human, sheep and rat, respectively at day 6 of culture. The albumins were also purified from blood serum of buffalo, goat and rat using salt fractionation, ion-exchange chromatography, gel filtration and SDS-PAGE. The highest stimulatory effect on progesterone secretion was shown by albumin purified from buffalo blood serum and lowest by that from rat blood. Comparatively the buffalo and goat albumins were more biologically active than commercial albumins. The presence of some active molecules conjugated with freshly purified albumins may be responsible for better stimulatory effect.
