An 11-year-old, Shorthorn cow, reared near Gort Co. Galway, Ireland, needed assistance to calve. The cow became a downer on that day postpartum (pp). Injection-acupuncture with dexamethasone was used at lumbo-sacral space, GB30, ST36, GB31, BL40, ST40 and ST41. In addition, modified moxibustion was received at session 1. At session 2, the cow could not stand. At session 3, the cow tried to stand twice by herself but fell down again each time. However, she stood up with slight help on 10 days pp. The present patient was a case with downer cow syndrome which showed improvement of clinical symptoms by injection-acupuncture with dexamethasone plus modified moxibustion.

This study was conducted to investigate reasons for culling of Chungcheong dairy herds and to investigate the relationships between cow parity, interval from calving to culling, or season and culling reasons. Lactation data from 826 cows on 9 dairy farms from 2013 to 2015, including reasons for culling, dates of birth, last calving, and culling, were analyzed. The overall culling rate was 29.8% (246/826), with mammary problems (23.2%) being the most prevalent reason for culling, followed by infertility (14.2%) and downer cow syndrome (11.0%). The culling rate varied among farms (18.8-43.1%, p < 0.05), but was greater in parity $4{\leq}(40.7%)$ than parities 1, 2, or 3 (17.9-23.6%), whereas the rate was less frequent during mid lactation (21.1%) than in early (36.2%) or late (42.7%) lactation. Moreover, the culling rate was greater during summer (35.8%) than other seasons (20.3-23.2%). Mammary problems, downer cow syndrome, and metabolic disorders were the more common reasons for culling during early lactation, whereas infertility was predominant during late lactation. Our data show that the culling rate in Chungcheong dairy herds was associated with cow parity, interval from calving to culling, and season, with the main reasons for the removal of cows from dairy herds being mammary problems, infertility, and downer cow syndrome.

This study was performed to investigate the effects of recombinant BST formulation treatment on the milk yield, milk components, mastitis, and general cow health condition when the formulations of retinyl palmitate, cholecalciferol and rBST were administered after the peak period of milk production. The milk yields of treatment groups (Group I, II, III and IV) were increased from 21.5% to 29.0% than that of control group. There was significant difference in milk production between treatment group II, IV and control group (P<0.05). However, there was no significant difference in milk production between treatment group I, III and control group (P<0.05). And the addition of retinyl palmitate and cholecalciferol into rBST formulation did not increase the milk yield. The milk of treatment groups with sustained-release rBST did not show significant difference in milk components (milk fat, protein, lactose, and solid not fat). However, there were minor changes, primarily in fat content of milk, during the first few weeks of rBST administration. There was no incidence of clinical mastitis between rBST treatment groups and control group. Addition of high and medium concentration of retinyl palmitate and cholecalciferol into sustained-release rBST formulation was efficient in reduction of somatic cell count in milk. There was great energy deficit in all treatment groups compared with control group during the early study period. Thus, the body condition score of all treatment groups showed lower value than control group. No evidences of metabolic health problems, such as ketosis, milk fever, and downer cow were observed. Incidence of general lameness did not appear on all treatment groups during 140 days of this study.

Bovine parainfluenza virus type 5 (bPIV5) was isolated from cattle with downer cow syndrome in 2012, and included both respiratory and neurotropic pathogens from a variety of animals. In the current study, we conducted serosurveillance using sera obtained from seven Korean farms and optimized a reverse transcription-polymerase chain reaction (RT-PCR) assay to detect bPIV5. The overall seropositive rate for Korean cattle was 21.4% (163/760). A farm located near the city of Milyang in Gyeoungnam province had a markedly elevated seropositive rate for bPIV5 compared to that of the other six farms. The regional seropositive rates were 4.2% (8/192) for Haman, 19.5% (18/55) for Hwasung, 73.9% (65/88) for Milyang, 26.0% (50/192) for Namwon, 1.0% (1/96) for Uljin, 13.5% (13/96) for Yeongju, and 32.7% (8/41) for Yongin. The sensitivity and specificity of three RT-PCR primer sets used to amplify the conserved fusion gene of bPIV5 were also evaluated. An RT-PCR assay using the bPIVFR3 primer set was 10-fold more sensitive than the assays using the two other primer sets and did not result in non-specific amplification. These results demonstrated that the bPIFR3 primer set can be used to detect bPIV5.

The present study was performed in order to clarify the significance of serum amyloid A(SAA) estimation for the diagnosis of bovine amyloidosis and SAA as a useful parameter for the health status in herds. Twelve dutch dairy cows with final diagnosis(2 with amyloidosis, 3 with acute inflammatory disease and 7 with chronic inflammatory disease) were used to charify the significance of SAA determination for the diagnosis of bovine amyloidosis. The SAA concentration in the group of inflammatory disease was higher than that of amyloldotic group. Further the SAA value in the group of acute inflammatory disease was higher than that of chronic ones. To clarify the significance of SAA estimation as a useful parameter for the health status in herds, two Korean dairy farms(A and B) were selected and the SAA concentration was determined in total 76 cows(49 from A farm and 27 from B farm). The SAA concentration in cows from A farm was ranged with 0～169%. The cows with high level of SAA(31～169%) had the disease histories(1 with retained placenta, 3 with chronic mastitis, 2 with acute mastitis, 1 with abortion and acute mastitis, 1 with ovarian dysfunction, 1 with downer cow syndrome and 1 with laceration of the teat). The SAA value in the cows from B farm was ranged with 0～29% and disease history was not detected. In conclusion the SAA determination only is thought to be difficult for the diagnosis of bovine amyloidosis. Furthermore SAA estimation is thought to be a useful parameter for the health status in herds.

Since successive operations under the acupuncture analgesia have been reported In China 1971, veterinary acupuncture was brought to the attention over the world and then its research and clinical use have markedly developed. Veterinary acupuncture and moxibustion was originated in China and Korea, but the research activities on them were not very significantly advanced. In this study, status of veterinarians on veterinary acupuncture and moxibustion, acupunctures which has been practiced by civil acupuncturist, therapeutic effects of acupuncture for the animal diseases in the field, and effects of electric acupuncture on the lumen motility in ruminants, etc. were Investigated. One-fifty of veterinarians of private clinics in Korea was interested in acupuncture and moxibustion in veterinary medicine. A lot of veterinarians required the scientific, systemic technique and knowledge or acupuncture. Civil acupuncturists who have been practiced acupuncture and moxibustion were 20 persons, and most of them were very old. They used chiefly three edged needles which were made by themselves and utilized old traditional technique in which the acupoints were stimulated and bled. Treatment with acupuncture for the digestive, muscular locomotive and febrile diseases was very effective. Until nowadays, the research on veterinary acupuncture in Korea has not much progressed. However, the Korean Societh of Veterinary Acupuncture and Moxibustion was organized in 1990. Valuable development for acupuncture through the society are expected. Electroacupuncture regional analgesia on the combinations of Yao-Pang 1, 2 and 4 acupoints was very effective for abdominal operations in cattle. But a lot of experiences and studies on the acupuncture anesthesia were required for clinical use in the future. Therapeutic effects of about 80% were obtained from electroacupuncture on the combinations of Tian Ping-Bai Hui-Shi Zhang, and Guan Yuan Yu acupoints in cattle with luminal atony and tympany In the field. Electroacupuncture on the combination of Tian Ping-Bai Hui-Qi Men, and Tian Ping-Bai Bui-Wei Gen for the treatment of downer cow was not so effective. The effects of stimulation and bleeding from acupoint by three edged needle was excellent for febrile diseases. The luminal contractile movement was accentuated by electroacupuncture on Tian Ping-Bai Hui-Shi Zhang combination and Guan Yuan Yu acupoint. It was concluded that veterinary acupuncture and moxibustion should be utilized for veterinary practice, and the advanced scientific research and clinical experiences must be followed.
