  • The aim of this study was to estimate genetic parameters and annual trends on the racing performance of Thoroughbred horses by a statistical analysis of the resulting records. We used the racing results of 245,979 observations for 13,458 horses recorded in 19 years of race held at Seoul and Busan racing tracks, provided by Korea Racing Authority. After a careful adjustment of some variables such as racing times, jockey and trainer numbers and the average prize a horse won, we selected significant factors that explain the result of racing records of a horse by stepwise AIC and BIC methods. The estimated heritability and repeatability were 0.322 and 0.332, respectively. The average of annual phenotypic and genetic improvement was -0.166 seconds and -0.161 seconds, respectively. Based on the statistical approach, we established reasonable animal model of well-set variables, which is important in the study on estimating performance of racing horses.

  • This paper dealt with the distribution of normal mast cells in the spleen, liver and lung on cattle, horses, pigs and dogs, and also degranulation of mast cells in the dogs infected with Rompun (2% Xylazine HCl). The results observed are summarized as follows. Normal mast cells were distributed in spleen, liver and lung on cattle, horse, pig and dog. Mast cells were observed in both red pulp and surroundings of white pulp of the spleen in horse, in the white pulp of the spleen in cattle, in the trabeculae of the spleen in pigs, and in white pulp and red pulp of the spleen in dogs, respectively. Mast cells were observed in the portal triad of the liver in cattle and horses, in both portal triad and interlobular connective tissues of the liver in pigs, and not only the portal triad but also walls of the sinusoids and the central veins in dogs. A large number of mast cells were observed in the interlobular septa and peribronchioles of lung on all the species in this experiment. The mast cells are more numerous in the lungs than other organs. Author considers that numbers of normal mast cells distributed in the tissue is related to the dosage of Rompun in animal. The degranulation of mast cells were observed in the subcutaneous tissues of dog intramuscularly injected with Rompun(0.5ml/times) for 4 or 5 times and subcutaneously injected with Rompun(0.3ml/times) for 4 times. In dog intradermally injected with 0.1ml of Rompun, mast cells were decreased in number at 30 minutes and markedly decreased in number at 2 hours, but more or less increased in number at 3 hours after injection. In addition, the granules of the mast cells were decreased in number at 30 minutes and marked degranulation of the mast cells were recognized at 2 hours after injections, but normal mast cells begun to appear in subcutaneous tissue with the lapse of time from 3 hours after injection. There was also observed local infiltration of neutrophils in subcutaneous tissues of dogs intradermally injected with 0.1ml of Rompun at 30 minutes. At 2 hours after injection, numerous neutrophils and a small number of eosinophils were observed in the site of injection. Conclusionally, Rompun was regarded as a factor which causes the degranulateon of mast cell and the authors considered that histamine released from the mast cells by Rompun might cause relaxation of skeletal muscle.

  • The present study was carried out to investigate the blood markers of Cheju horses. The blood protein types (biochemical polymorphism) were tested from 73 Cheju native horses (CNH) and 118 Cheju racehorses(CRH) by horizontal polyacrylamide gel electrophoresis (HPAGE), isoelectric focusing (IEF) and starch gel electrophoresis (SGE). At the same time, their phenotypes and gene frequencies were studied. The biochemical polymorphism phenotypes observed with high frequency were A1B-KK(97.3%), ALB-AB(49.3%), AP-SS(100%), ES-II(30.1%), GC-FF(87.7%), HB-BIBI(49.3%), TF-F2R(41.1%), TF-EF2(8.2%), PGD-FF(97.3%), PGM-SS(50.7%), GPI-II(74.0%) in CNH, While A1B-KK(99.2%), ALB-BB(50.8%), AP-SS(99.2%), ES-II(42.4%), ES-IS(14.4%), GC-FF(95.8%), HBB-IB II(39.8%), TF-F2R(21.2%), PGD-FF(77.1%), PGD-SS(4.3%), PGM-SS(72.9%), GPI-II(90.7%) in CRH. Alleles observed with high frequency were $AlB^{K}$(0.986), $ALB^{B}$(0.616), $AP^{S}$(1.000), $ES^{I}$(0.479), $ES^{F}$(0.274), $GC^{F}$(0.938), $GPI^{I}$(0.856), $HB^{BI}$(0.685), $PGD^{F}$(0.993), $PGM^{S}$(0.753), $TF^{F2}$(0.404), $TF^{R}$(0.397) in CNH and $AlB^{K}$(0.996), $ALB^{B}$(0.720), $AP^{S}$(0.996), $ES^{I}$(0.661), $ES^{F}$(0.203), $GC^{F}$(0.979), $GPI^{I}$(0.936), $HB^{BI}$(0.534), $PGD^{F}$(0.864), $PGM^{S}$(0.852), $TF^{F2}$(0.428), $TF^{R}$(0.272) in CRH. $TF^{E}$(0.041) allele and silent gene($ES^{I{^*}}$ : 0.014) were observed in CNH. The mean heterozygosity in CNH and CRH was observed 0.2974 and 0.2864, respectively.

  • These studies were carried out to develop some easy-checking thermometers instead of taking temperature of ectum for the farmers to detect easily a diseased animal with fever. Thermometers such as pincher-type, hood-type, raser-type, stick-type, and wrap-type were devised for the experiments. The experimental animals were cattle, horse, swine, aprine, and canine. Temperature-taking parts of the body were ear, shoulder, axilla, gluteal part, and coccygeal part according o the devised thermometer. Rectal temperature was taken at the same time for the comparison of temperature between rectum nd the certain part. The difference of temperature between rectum and shoulder part using eraser-type thermometer for the domestic animals were $3.37^{\circ}C$ for cattle, $1.94^{\circ}C$ for horses, $2.04^{\circ}C$ for swine, $1.27^{\circ}C$ for caprine, $0.9^{\circ}C$ for canine. The difference of temperature between rectum and gluteal part using eraser-type thermometer for domestic animals were $3.46^{\circ}C$ for cattle, $1.98^{\circ}C$ for horses, $2.22^{\circ}C$ for swine, and $1.1^{\circ}C$ for canine. The difference of intra-individual temperature taken by eraser-type thermometer of shoulder and gluteal part were 0.3 and $0.8^{\circ}C$ for cattle, 0.7 and $1.1^{\circ}C$ for horses, 0.6 and $0.7^{\circ}C$ for swine, 0.9 and $1.1^{\circ}C$ for canine. The difference of temperature between rectum and shoulder part taken by hood-type thermometer for cattle was $3.93^{\circ}C$ and the difference of intra-individual temperature was $0.8^{\circ}C$. The difference of temperature between rectum and gluteal part taken by stick-type thermometer for cattle was $3.7^{\circ}C$ and the difference of intra-individual temperature was $0.8^{\circ}C$. The other types of thermometers than the above three were not proved to be reliable to detect temperature of domestic animals. It was concluded that hood-type, stick-type and eraser-type thermometers are recommendable devices of thermometer to detect easily the status of body temperature and that the eraser-type was proved to be a practical one of the thermometers used in this study.

  • The Purpose of this study is to introduce traditional Mongolian costume easily and shortly in various ways. The Mongolian costumes are very simple and convenient to wear because they are made in consideration of Mongolian culture in which people live with livestock and ride horses every day. Furthermore, they are associated with traditional national ceremonies. It is interesting the Mongolian costume is similar to Korean Hanbok. More studies of Korean costume and Mongolian costume will be significant for cultural and historical interchanges between two countries.

  • Intestinal adenocacinomas are uncommon in dogs, and they occur most frequently in the colon and rectum of animals averaging 8-9 years old. Also, they have been reported rarely in cattle, goats, horses and swine. This tumors occur slightly higher in males than in females. Boxers, collies, poodles, and German shepherds are prediposed.
