In the present study, the incidence of bovine tubeculosis (bTB) and brucellosis in Hanwoo (Korean native cattle) and dairy cow in Gyeongsangnam-do was investigated for three years from 2020 to 2022. The incidence bTB tested by tuberculin skin test with purified protein derivative (PPD) and gamma interferon (γ-INF) test with a commercial enzyme-linked immunosorbent assay. From 2020 to 2022, the incidence of bTB showed a decreasing trend in Hanwoo, while an increasing trend in dairy cow. In the case of Brucellosis, the positive rates for Hanwooe gradually increased. However, no brucellosis was found in dairy cow from 2020 to 2022. The increase in the incidence of these diseases is presumed to be related the small scale and poor sanitation facilities of livestock farms in Gyeongsangnam-do, and easy access of wild animals. Therefore, in order to suppress the incidence of the diseases, it is necessary to the farm scale from small to large and to strengthen sanitary facilities on farms.

Pathogen infections or mastitis inflammations usually develop differently on each udder of lactating cow. Although healthy udders will be attacked by the mastitis pathogens or the pathogens from blood in a long term, they would not be always inflamed. Somatic cell counts (SCC) in milk, which is utilized as an index of mastitis diagnosis, and the relation among SCC and milk constituents will have to be examined on each udder individually. Twelve cows of a Holstein cow herd in Nasu Research Station, which were suffering clinical or non-clinical mastitis, were selected, and SCC and milk constituents on each udder milk were measured. The effects of mastitis infection on udder milk components were relatively small except lactose content on udder milks of non-clinical mastitis (SCC< $10.0{\times}10^5$ per ml milk). On udder milks of clinical mastitis, however, high negative correlations were recognized between SCC and milk components. On different sampling days, high contents of fat and protein corresponded to that of total solids.

As a fundamental study to increase the fertility and to modify the sex ratio in cattle, highly motile sperm were separated by bovine serum albumin gradients. The pregnancy rates of Korean native cow and Holstein cow, and the sex ratio between AI and natural mating were also investigated. The results obtained were as follows. 1. First service pregnancy rate of Korean native cow in artificial insemination was higher than that of Holstein. 2. At secondary sex ratio in artificial insemination and natural mating, male ratio in artifical insemination was slightly higher than that in natural mating. 3. The sperm separated from marketed frozen semen using 6%, 10% and 20% bovine serum albumin showed significantly high value in motility, percent of normal sperm and progressive motility as compared with control sperm.

The objective of this study was to compare occurrence of the shipping fever associated with vaccination and mass medication in Korean Native Cow. Lack of vaccination (Pasteurella haemolytica, infectious bovine rhinotracheitis, bovine viral diarrhea, parainfluenza 3, and bovine respiratory syncytial virus) and mass medication before and after transportation, 67% of gram-negative cocci were detected. However, with vaccination and mass medication, only 33% of Gram-negative cocci were detected. When antimicrobial susceptibility for the detected bacterium was tested, apramycin, ampicillin, amilacin, clindamycin, gentamycin, kanamycin, penicillin, and streptomycin were resistant, whereas tylocin, amoxicillin, linocospetin, nalidixic acid, norfloxacin, oxalinic acid, and cefotaxime were susceptible. Morbidity and average therapeutic effect were 33% and 1.0time with vaccination and mass medication and were 78% and 5.3 times without vaccination and mass medication, respectively. Therefore, the results suggest that shipping fever would be considerably decreased with vaccination including mass medication before and after transportation.

In September 2001, BSE was found for the first time in Japan. From then, consumers have been more and more interested in the safety of food products. Therefore, breeders and participants have to make a tracing system of productive information of cows and guarantee the quality of products through that system in an emergency Then the government has decided to put ear tags with peculiar numbers on all the cows and control the information of individual production and transference. But the ear tag can be damaged and missing. There is also a research of identification by implanting a microchip into the cow's body. But there are problems that the research can give a distress on cows and the detectable distance is too short. (omitted)

This research was carried out to find the mordant effects by Tara and Myrobalan as natural tannins on the cow leather dyed with Lac powder. The cow leathers were treated with Tara, Myrobalan, Al, Cu, and Fe mordants by changing treatment orders. It was examined for K/S value, surface color changes, and color difference. The K/S value generally has higher Myrobalan than Tara, and pre-mordant than post-mordanted condition. Cu is the strongest among the three mordants. As a results of the treatment order, the K/S value is higer in pre-tannin-mordant agent than in pre-mordant agent-tannin. In the post mordant, K/S value is higher in mordant agent-tannin than in tannin-mordant agent. The color difference and color factors such as H, V and C were various according to the mordant agents, treatment orders and mordant methods; and surface colors of dyed cow leathers were R and RP. It was difficult to find some significant means of mordant orders.

The present study investigated the use of cow faeces as a source of micro-organisms instead of sheep rumen liquor in in vitro digestibility assays of forages. Initially 40 forage samples comprising ryegrass, wheat, maize and barley were screened to select a wide range of digestibility (327-794 g/kg) of forages. Finally 8 forage samples were assessed using rumen liquor as well as faecal liquor. The absolute organic matter digestibility (OMD) values using faecal liquor were lower than those with rumen liquor. However, the relationship between OMD using rumen liquor and faecal liquor was highly significant (p < 0.001). The $R^2$ value exceed 0.90. The results suggest that micro-organisms from faecal liquor are capable of digesting forage samples.
