Bacteroiospermia is a frequently finding in fresh raw and extended porcine semen and can results in detrimental effects on semen quality and longevity. This study aims to evaluate the type of bacterial contaminants in raw and extended porcine semen and the reducing effect of antibiotic test. To investigate bacterial contaminants, out of 387 sample (raw semen 201, extended semen 186) were collected from 6 artifical insemination centers in Gyeongsangnam-do, were inoculated onto blood agar and MacKonkey agar, respectively. Bacterial colonies were selected after culturing for 48 hours, at
, followed by Gram staining, KOH test, oxidase test, catalase test and eventually identified using VITEK System. Total 15 genus and 24 species of bacteria were isolated from these semen samlpes. In raw semen, the most prevalent contaminants were Pseudomonas aeruginosa, Escherichia coli, Proteus mirabilis, Staphylococcus auricularis, Delftia acidovorans, Acinetobacter lowffii, S. aureus and others. And in extended porcine semen, A. lowffii, S. aureus, S. auricularis and other bacteria were identified. Most of them was G(-), which is nonpathogenic bacteria. It seems that bacterial contaminants in fresh raw and extended porcine semen originated from multiple sources at the farms/stud, and were from animal origin and non-animal origins. Whereas, the 7 virus which is known to be detected in porcine semen in 75 cases was not detected. This results showed that removal of bacterial contamination in raw and extended porcine semen is essential and farms were kept for biosecurity and individual hygienes.

The prevalence of major zoonotic diseases such as tuberculosis, brucellosis and the highly pathogenic avian influenza (HPAI) in Jeonbuk province was monitored from 2004 to 2008. For tuberculosis, a total of 306 heads from 92 farms were positive during the surveillance period, which 228 heads were from 78 dairy farms and 78 heads from 14 Hanwoo farms. Based on the number of recurrent tuberculosis in 92 positive farms, 28 farms or 43.8% of the positive farms had 1-4 additional outbreaks during the surveillance. Based on brucellosis surveillance of 5,252 dairy cattle and 2,600,829 Hanwoo conducted during the same time period, 4,818 heads from 1,203 farms were positive for brucellosis, which 445 heads were from 111 dairy farms and 4,373 heads from 1,092 Hanwoo farms. Among the 1,203 positive farms, 473 farms or 39.3% of the positive farms had experienced 1-4 recurrent brucellosis during the surveillance. According to nationwide surveillance of HPAI, a total of 45 cases had been reported between 2004 and 2008. Among those outbreaks, 20 cases were reported in Jeonbuk province and 3 cases in 2006 and 17 case in 2008. For the regional distribution of 20 cases in Jeonbuk, 4 cases (48,490 chickens), 4 cases (23,066 chickens 66(1) and ducks 23,000(3)), 11 cases (183,077 chickens 63,077 (10) and quails 120,000 (1)), and 1 case (9,000 ducks) were reported in Iksan, Jeongeup, Gimje and Sunchang, respectively.

On the basis of the 2009 business plan, 20,394 Korean native cattle and beef cattle were carried examination of bovine tuberculosis by using ELISA technique from March to December. As a result, 66 cattle tested positive for tuberculosis and showed 0.32% positive ratio. Intradermal tuberculin test about 66 cases of ELISA positive cattle was carried out, and all of 66 cattle were confirmed as negative. However, when 7 PPD-positive cattle derived from slaughterhouse were tested by 20k ELISA kit and MS ELISA kit, 3 (2 suspect) cattle and 5 cattle showed positive results, respectively. As compared to the results of PPD test, the concordance rates were 43% (71% included suspect) with 20k ELISA kit and 71% with MS ELISA kit.

Korean Journal of Veterinary Service, volume 33, issue 4, 2010, Pages 341~344
Poultry and poultry products have been implicated as a major source of Salmonella infection in human, and infection due to Salmonella serotypes continue to be a major health problem. The presence of two virulence genes, invA and spvC, in 34 Salmonella isolates obtained from duck farms was investigated. All isolates contained the invA gene, and spvC gene was found in 20 (58.8%) of 34 Salmonella isolates : S. Typhimurium (n=8), S. Fyris (n=5), S. Enteritidis (n=3), S. Typhimurium var. copenhagen (n=1), S. Haardt (n=1) and S. Mbandaka (n=1). This study showed the presence of the spvC gene was widely distributed in between different Salmonella enterica isolates.

Toxoplasma gondii is a species of parasitic protozoa in the genus Toxoplasma. The definitive host of T. gondii is the cat, but the parasite can be carried by the vast majority of warm-blooded animals, including humans. It is often found in the tissues of food animals including pigs and sheep. To determine the regional prevalence of infection with T. gondii, bloods (n=300) from domestic pigs and tissues (n=200) from slaughter pigs in Gyeongnam province were tested using an enzyme-linked immunosorbent assay (ELISA) and a polymerase chain reaction (PCR) for detection of antibody and antigen. A total of 115 sero-positive pigs were identified for a prevalence rate of 38.3%. Of the 50 herds from domestic pigs tested, 34 had at least one sero-positive pig for a herd prevalence rate of 68.0%. Sero-positive rates of pigs in fattening farm were higher than that of pigs in breeding company. Sero-positive rates of sows were higher than that of growing pigs. Seasonally, sero-positive rates of pigs were highest in winter (80.0%) and lowest in spring (23.8%). According to farm size, sero-positive rates of pigs were higher in small size farms (
2,000) than that of big size farms (>2,000). However, none of the bloods (n=300) from domestic pigs and tissues (n=200) from slaughter pigs were positive for T. gondii specific DNA by PCR.

Nucleotide sequences of mitochondrial DNA (mtDNA) of 19 leopard cats (Prionailurus bangalensis euptilura) obtained from Seoul grand park zoo in South Korea were determined for analysing genetic diversity. In the leopard cats, 3 haplotypes of the partial cytochrome b sequences (603 base-pairs, bp) were identified. Haplotypes obtained from those genes showed existences of at least 3 maternal lineages of leopard cats in Korea. Tamura-Nei nucleotide distance among 3 haplotypes were 0.00. Molecular phylogenetic tree showed the similar clustering of haplotypes for genes. Meanwhile, no individual variations within the leopard cats in S. Korea. Genetic surveillance system of leopard cats in S. Korea is warranted for maintaining biological conservation.

This study was carried out to investigate the characters of short-tailed dogs (DongGyeong dogs) with anatomical insights, molecular genetics in Gyeongju. The present study was conducted to further characterize of short-tailed dog population in Gyeongju. The short-tailed dog was analyzed in the distribution of 55 individual. The anatomical insights were by x-ray. For discovery of specific genes expressions were measured by Hot-start PCR analysis. Anatomy survey, the number of vertebral typical consists of more than 20. 88.9% of short-tailed dog populations consists of 3-8 vertebrates. The 54 individuals of the 47 observe the vestigial tailed of the sacrum. No detected sacrococcygeal vertebrae degradation individuals were malformation defects. The 3 genes were DEGs (differentially expressed genes) in Dong-Gyeong dogs. We succeeded in finding 3 novel DongGyeong dogs specific genes by using Hot-start PCR analysis, this study suggests that these novel genes may play role (s) in DongGyeong dogs.

Investigations for hematologic and biochemical values for Gyeongju DongGyeong dogs were performed. This study were conducted to determine normal blood and serum chemical values on DongGyeong dogs. Normal blood and serum chemical values were studied in 47 healthy dogs (male 28, female 19). The hematologic and serum chemistry results were confirmed by age, sex, shape of tail. The hematological values showed no difference from Korea native dogs. The hematocrit values (
(%)) of DongGyeong dogs (2-3 years group) were significantly higher than other dogs. The mean levels of MCV (
) in DongGyeong dogs were lower than general dogs. The levels of cholesterol(
(mg/dl)) and inorganic phosphorus (
(mg/dl)) of DongGyeong dogs (2~3 years group) were significantly higher than Korea native dogs. Totally concentration of triglyceride (
(mg/dl)) of DongGyeong dogs were significantly lower than Korea native dogs. The mean values of BUN were increased with age but no significantly. In conclusion, data obtained from this study may be valuable as a standard for interpretation of the results in hematologic and biochemical analysis of Gyeongju DongGyeong dog populations.

An investigation was conducted to evaluate the effects of supplementing Alisma canaliculatum, Viscum album and Cornus officinalis probiotics on the growth performance and immune response in growing pigs. This experiment was conducted using 120 pigs (crossing of Landrace
Yorkshire and castrated) which were assigned to 5 treatments in 3 replications with 8 pigs per replications. The dietary treatments were NC group (without antibiotics), PC group (basal+Oxytetracycline 50ppm), AC group (basal+A. canaliculatum 0.5%), VA group (basal+V. album 0.5%) and COP group (basal+C. officinalis probiotics 0.5%). The initial body weights of pigs were 35kg on average and the experiment lasted for 9 weeks. The experimental animals were kept in the pens following a completely randomized design. They were provided the diets adequate for grower stage as recommended by NRC (ME:3,265 kcal/kg and CP:16%). COP fed pigs showed lower weight gain up to 6 weeks of age compared to NC group and other groups without significant differences (P>0.05). The carcass weights of pigs fed VA and COP were significantly higher compared to NC group (P<0.05), Back fat thicknesses groups fed three different additives were higher than NC group and lower then PC group (P<0.05). Crude fat contents in loin meat were significantly lower in groups fed three different additives while moisture contents of those three groups were higher than other groups (P<0.05). The thiobarbituric acid reaction substance (TBARS) value measured at fresh and
weeks was lower in additives fed groups but no statistical differences were observed among the treatments (P>0.05). Significantly highest PUFA (16.42g/100g) and
-3 fatty acids (ALA, EPA and DHA) content of meat were observed in COP fed pigs compared to NC group (P>0.05), which might mean that three additives function to enhance serum IgG in pigs. In consequence, it can be suggested that AC, VA and COP may have a potential to replace antibiotics as growth promoter and immune enhancer in the diets for growing pigs.

This experiment was conducted to investigate the effect of fermented spent mushroom substrate (FSMS) on growth performance, blood profile, intestinal microflora and ammonia gas production of feces in broiler chickens. A total of three hundred sixty, 1-day-old male broiler chicks (Ross) were randomly divided into 3 groups with 6 replicates of 20 birds each. The treatments were control (free FSMS), 15% FSMS (basal diet with 15% FSMS) and 30% FSMS (basal diet with 30% FSMS). The final body weight and body weight gains were slightly improved in 30% FSMS than control (P<0.05). Feed intake and feed conversion were significantly improved as compared to those of the control groups. The Leukocytes of blood serum in FSMS groups were significantly decreased as compared to those of control groups. There are no significant differences among the groups in the contents of albumin (ALB), total cholesterol (TCHO), glucose (GLU), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in blood serum. The content of total glucose (TG) in 30% FSMS containing dietary groups was significantly decreased as compared to that of the control groups. The content of HDLC in 30% FSMS containing dietary groups was significantly increased as compared to that of the control group. The number of lactobacillus in the intestinal microflora were significantly increased in chicks fed FSMS groups. The ammonia gas production in FSMS groups was siginificantly decreased as compard to that the control groups. These results indicated that dietary FSMS exerted growth performance for feeding broiler.

We analyzed the HACCP prerequisite of National Veterinary Research and Quarantine Service (NVRQS) and the Food Establishment Inspection Report of US Food and Drug Administration (FDA) to recommend contents and ranges to be complemented and used for preparation of guidelines for more effective application of HACCP prerequisites. We used the HACCP inspection reports implemented by Korea Livestock Products HACCP Accreditation Service from 2007 to 2009, FDA Food Code 2009 Guide 3-B Instructions for Marking the Food Establishment Inspection Report, and Retail Food Establishment Sanitation Requirements of 410 Indiana Administrative Code. Major non-compliance items were open doors and windows, insanitary cleaning of in-use utensil, inadequate record of warehousing, and improper storage, transportation, and labelling. Hot water supply, personal hygiene, and regular product testing were additional week points which should be more strongly controlled by detailed operating guidelines. Also, current prerequisite items were required revision into more precise contents to enhanced the effective evaluation and practical application in meat markets.

From 2006 through 2007, the highest need for the most urgent attention in Gangwon-do Wild Animal Rescue Center was wildlifevehicle collisions (WVC). The Korean Ministry of Environment reported 6543 WVC's in 2005 and 5565 cases of WVC's in 2006. In this study, data from the Gangwon-do Wild Animal Rescue Center was utilized to analyze WVC incidents and the movement of wildlife near roadways in Korea. From 2006 through the first half of 2008, the portable GPS device recorded accident location of the injured wildlife. Attempts were made to track and monitor the movements of four raccoon dogs and five Korean water deers near the roads. One raccoon dog and one Korean water deer were successfully tracked and monitored. Their locations were transmitted to cell phones. The amount of WVC's was highest amongst the roads near the forests of Gangwon-do. The devices installed on the nearby roads did not protect the wildlife from WVC's. Results using the CDMA-type GPS collar showed that wildlife often crossed the road even with devices installed to prevent this from crossing roads. This research analyzed the behaviors of different wildlife animals and WVC's. New preventative measures need to be established to avoid roadkill. It is suggested that new streets be built or for an appropriate speed limit be implemented.

The present study was devised to determine the effects of body weight, organ weight, hematological values and biochemical parameters by vitamin E and selenium (Selevit) in the ovariectomized (OVX) rats. The animals were divided into 4 groups. Intact group (n=10) received no treatment and operation. Sham group (n=10) received only sham operation and no treatment. OVX group received operation and no treatment. OVX+Selevit received operation and Selevit. The body weights of the all group increased, and that of OVX+Selevit group was the lowest rates. There were significant differences (P<0.01, P<0.001) of body weights between OVX+Selevit group and all other groups. Also, organ weights such as heart, liver, spleen and kidney were measured. The heart and liver weight were significantly lower (P<0.01, P<0.001) in the OVX+Selevit group than in the Intact and Sham group. Also, the kidney weight was significantly lower (P<0.05, P<0.01) in the OVX+Selevit group than in the all other group. On the other hand, there was no significantly difference in the organ weight of spleen between the OVX+Selevit group and the other groups. The number of WBC was significantly higher (P<0.05) in the OVX+Selevit group than in the all other groups. The hematological values of RBC, MCV, MCH and MCHC were no significant differences in any groups. The biochemical parameters of serum total protein and alkaline phosphatase increased significantly in the OVX+Selevit group as compared to that in the OVX group. But, there were no significant differences in AST and ALT in any groups. We conclude that vitamin E and selenium were significantly decreased the body weights in the ovariectomized rats. Our findings suggest that vitamin E and selenium may influence the process of lipid packaging and absorption in the ovariectomized rats.

The aim of this study was to determine the changes of body weight, organ weight, hematological values and biochemical parameters by testosterone (Testos) on the orchidectomized (Orch) rats. The animals were divided into 4 groups. Intact group (n=10) received no treatment and operation. Sham group (n=10) received only sham operation and no treatment. Orch group received operation and no treatment. Orch+Testos received operation and testosterone. The body weights of each group increased, but that of Orch+Testos group was significantly lower in Orch+Testos group than in all the other groups. There were significant differences (P<0.05, P<0.001) of body weights between Orch+Testos group and all the other groups. Also, organ weights such as heart, liver, spleen and kidney were measured. The heart weights were significantly lower (P<0.001) in the Orch+Testos group than in all the other groups. The liver weights in the Orch+Testos group were significantly differences in comparison with those in the Sham (P<0.001) and Orch group (P<0.05). On the other hand, there were no significantly differences in the organ weights of spleen and kidney between the Orch+Testos group and the any other groups. The hematological values of white blood cell (WBC), red blood cell (RBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) were no significant differences in any other groups. The concentrations of serum total protein and albumin increased significantly (P<0.05) in the Orch+Testos group as compared to that in the Orch group. However, there were no significant differences in Ca, IP and Mg in any other groups. We conclude that testosterone was significantly decreased the body weight in the orchidectomized rats. Our findings suggest that testosterone may influence the process of lipid packaging and absorption in the orchidectomized rats.
