Research results on actual management situation of 16 goat farms and internal parasite infection of 155 goats from January to November in 1997 in southern Kyoungnam area were as follows ; 1. An average number of goats was 93. Among them, 81% were farming the goat as avocation with the income rate less then 50%, Eight-four percent of farms terminated the parasites more than twice a year, and the survey showed the black goats had a high digestive and respiratory disease infection rate. 2. The internal parasite infection rate of the black goat was 96.8% , the goats were infected with 13 types of parasites. Of them, Emeria sp was 87.1%, Ostertagia sp 55.5%, Paraphistanum sp 45.8%, and Moniezia expansa 20%, respectively. 3. On the survey of multiple infection rate, both double and triple infection were 19.4%, more than septuple-infection 15,5%, single infection 13.4%, quintuple infection 12.3 n, sextuple infection 9.0% and quadruple infection 7.7%, respectively. 4. Look over on seasonal infection rate, higher in fall and lower in winter. Especially, Paramishitom sp was higher in summer and winter, both Moniezia expansan and Bonaostom sp were higher in summer. 5. Research on the infection rate of parasites termination period revealed less-than-1-month period had 10-30 infection rate, the infection rate has increased sharply since 3 months passed after the goats were treated with parasite-cid.

Goats (Capra hircus) are one of the oldest species of domesticated animals. Native Korean goats are a particularly interesting group, as they are indigenous to the area and were raised in the Korean peninsula almost 2,000 years ago. Although they have a small body size and produce low volumes of milk and meat, they are quite resistant to lumbar paralysis. Our study aimed to reveal the distinct genetic features and patterns of selection in native Korean goats by comparing the genomes of native Korean goat and crossbred goat populations. We sequenced the whole genome of 15 native Korean goats and 11 crossbred goats using next-generation sequencing (Illumina platform) to compare the genomes of the two populations. We found decreased nucleotide diversity in the native Korean goats compared to the crossbred goats. Genetic structural analysis demonstrated that the native Korean goat and cross-bred goat populations shared a common ancestry, but were clearly distinct. Finally, to reveal the native Korean goat's selective sweep region, selective sweep signals were identified in the native Korean goat genome using cross-population extended haplotype homozygosity (XP-EHH) and a cross-population composite likelihood ratio test (XP-CLR). As a result, we were able to identify candidate genes for recent selection, such as the CCR3 gene, which is related to lumbar paralysis resistance. Combined with future studies and recent goat genome information, this study will contribute to a thorough understanding of the native Korean goat genome.

A total of nine Korean indigenous goats were used in a cross-over arrangement to give nine replicates per treatment, and they were housed individually assigned to 1 of 9 dietary treatments. Nine treatments were 0, 500, and 1000 ppm of quercetin supplementation in diets by mixing roughage and concentrate with different ratios (RC ratio) of 3:7 (RC 30), 5:5 (RC 50) and 7:3 (RC 70). Nutrient utilizations of dry matter, crude fat and NDF were not affected by neither RC ratio nor dietary quercetin (p>0.05), but the rate of crude protein and ADF increased in animals in RC 70 group regardless of quercetin supplementation (p<0.05). In addition, higher RC ratio increased (p<0.05) N retention and N retention rate. Total VFA, acetic acid, propionic acid, iso-butyric acid, butyric acid, iso-valeric acid and valeric acid contents were not affected (p>0.05) by dietary quercetin. Meanwhile, lower total cholesterol level exhibited in animals in RC 70 group compared to RC 30 or 50 groups, unrelated to dietary quercetin (p<0.05), however other plasma parameters were not influenced (p>0.05) by RC ratio and dietary quercetin. Our results indicated that both RC ratio and dietary quercetin may not directly affect the production indices and immune responses in Korean indigenous goat.

Anaplasmosis is a tick-borne disease mainly of cattle, sheep, and goats. Anaplasmosis in goat had been reported at last year by authors. The disease brought the economic losses in the goat farm in Chonbuk province. In order to treat the disease, a long-acting formulation terramycin injectable solution was used experimental animals which indigenous goats were sick with moderate anemia. We were devided into two groups was treated with single dosage (20mg /kg of body weight). one group was treated with single injection, the other group was treated with twice of the same dosage intramusculary injection. The results indicate that the use of long-acting terramycin would minimize clinical signs of anaplasmosis infection in goat. After treament the differrences of hematological appearences and parasitaemia were observed in the effect of terramycin treatment. obviously, increased value of RBC. HB and HCT, and parasitaemia by means of Giemsa staining and acrydine orange staining was observed decreased due to treatment.

While studies have been carried out on endoparasite infection from feces of Korean indigenous goats in multiple areas around the nation, there is no report in northern areas of Gyeongbuk province. Thus, this study was conducted to examine the rate of parasite infection from the fecal samples of goats raised on grass. From March to July in 2008, 108 fecal samples were taken from goats. Eggs of parasites were identified using flotation or sedimentation methods followed by microscopic examination. Overall infection rate of parasites from feces of goats were 99% (107 out of 108). The infection rates of nematode, cestode, trematode and protozoa were 37%, 23%, 0% and 99%, respectively. Among parasite eggs detected, nematodes included threadworms (20%), strongyles (16%) and whipworms (1%). The only cestode and protozoa detected were Moniezia expansa and Eimeria spp, respectively. In the rates of mixed infection, single was 61%, double 32%, and triple 6%.

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.

Following the death of more than 250 goats in one herd of 800 goats, imported from Australia, an epidemiological investigation was undertaken to determine the probable aetiology of this apprently mysterious disease. The syndrome was characterized by severe anemia(Hematocrit <20% ; normal range 24 to 48). All the affected animals were imported from Australia and all the motalities occurred during the period from September to November, 1992 Giemsa stain, acridine orange and indirect immunoflourescence tests were utilized in a survey involving 239 goats reared in Chonbuk Province. The positivity rates by acridine orange for anaplasmosis or piroplasmosis were 60.8% and 66.2% for imported and indigenous breeds respectively. It is tenatively concluded that the probable cause of death was anaplasmosis.

The present study was undertaken to clarify the changes in hematological values of Korean indigenous goats according to age. Blood samples were collected from 16 goats (5 females and 11 males) from birth up to the age of 6 weeks and the levels of various hematological values were analyzed. The body weight was increased from 2.54 kg at birth to 6.41 kg at 6 weeks age. The erythrocytes (RBC) counts and hemoglobin (Hb) values of goats were decreased at 2 weeks after birth, and increased gradually from 4 weeks after birth. The hematocrit (Ht) values were decreased until 4 weeks after birth, and increased at 6 weeks after birth. The mean cell volume (MCV) and mean cell hemoglobin (MCH) were decreased until 6 weeks after birth. The mean cell hemoglobin concentration (MCHC) was increased slightly from 2 weeks after birth. The red cell distribution width (RDW) was increased significantly at 2 weeks after birth, and decreased from 4 weeks after birth. The platelet (PLT) counts were increased significantly from 2 weeks after birth. The mean platelet volume (MPV) was decreased at 2 weeks after birth, and increased gradually from 4 weeks after birth. The total white blood cell (WBC) counts and the mean absolute numbers of neutrophil, lymphocyte, monocyte and eosinophil were increased from 2 weeks after birth. In conclusion, the data obtained from this study may be valuable as a standard for interpreting results of hematological analyses in Korean indigenous goats.
