Rolling Ball Viscometer에 依한 乳牛의 準臨床型 乳房炎의 感染率에 關한 調査硏究

朴玉潤,曺熙澤 진주산업대학교 1984 論文集 Vol.22 No.-

This study was conducted to find out the infection rate of subclinical type and suspected positive of mastitis of dairy cows using Rolling Ball viscometer. The tested fore milk samples were collected from 1604 teats of 404 Holstein which their somatic cell number had more than 250,000 per mililiter, and these cows were selected from 241 farms located in Kyung­nam province for months from March 1984 to October 1984. The comatic cell number were measured by the viscometer, and the relation between the number of somatic cells of the sample and the cause factors of mastitis were examed, and the results obtained were as follows. 1. The sample which its somatic cell number has less than 250,000 denoted as negative infection was 26.9%, between 250,000 and 490,000 denoted as suspected positive infection was 28.6% and more than 500,000 denoted as positive infection was 24.5%. 2. In the case of the infection rate, 53.5% was infected among 404 cows and 26.0% was infected among 1606 teats. 3. In the test of suspected positive infection and subclinical type according to farm scale, the small scale farm(raising 1 to 10 cows per farm) has 54.7%, the medium scale farm(11 to 20 cows) has 43.5%, the large scale farm(21 to 30 cows) has 50%., and more than 31 cows per farm showed negative infection rate. The less scale farm showed the hiher the % of suspected positive infection. 4. In the case of suspected positive and subclinical type rate according to milking methods, it was 53.8% by milker and 28.6% by hand. 5. In the case of suspected positive and subclinical type rate according to disinfection by soaking the treats into the anticeptic solution after milking, the disinfected cows have 40.5% and nondisinfected cows have 64.8%. 6. In the case of suspected positive and subclinical type rate accoring to the type of administraters, It was 48.1% by ranchman and 89.7% by herd man. 7. In the case of suspected positive and subclinical type rate according to the number of years for raising the cows(personel experiences), It was 44.0% in the case of one year's experience, 45.1% in 2 to 3 years, 58.6% in 4 to 5 years and 69.1% in the case of more than 6 years of experience As the feeding experience increased the infection rate of subclinical type of mastitis was decreased.

韓國 畜産 및 獸醫術에 關한 史的考察

朴玉潤 진주산업대학교 1970 論文集 Vol.6 No.-

1) From the age of old time to early Three Country ages (around A.D. 1-4), the normadism and the stock farming were one of the most important industries. But since A.D. 372 when budhism was introduced and our ancestors were began to feel it wrong to kill domestic animals. the livestock industry has been degenarated a little. Especially during the middle and late age of Three Country(三國時代), the compulsory policies of governors not to breed the animals were resulted in degeneration of livestock. 2) The introduction of rice crop in B.C. 1-2 and nations suspiction not to kill animal made our livestock industry backward. The same is true for any nations in Asian Countries where rice was grown and budhism was provailed. 3) A most of our nations in history was under the command of Chinese royal goverment, then, Korea had to pay all things chinese asked by name of brives so on. The by-products of livestock were also payable things as brives (so called Kongmul, 貢物) 4) In the three country(三國時代), the methods of superstition and Shamanism had been used as the mean of curing animals before Haeza, a saintry priest, A.D. 590, and after that, Shamanism and Veterfnary science seemed to be combined.
