A ten-year-old holstein cow was presented because of prolapse of the third eyelid and apparent hyperplasia of the right lower eyelid. Historical findings included increased appetite as well as polyuria and polydipsia for about two weeks. The most remarkable fadings on physical examination were a large periocular proliferative tissue and bleeding. Surgical incision was used both as a biopsy and therapeutic tool in holstein cow with mass. Histopathological examination of the mass revealed squamous cell carcinoma. Blood and milk tests of patient with squamous cell carcinomatosis were peformed, but normal values.

Automatic milking systems (AMS) rely upon voluntary cow traffic (the voluntary movement of cattle around a farm) for milk harvesting and feed consumption. Previous research on conventional milking systems has shown differences between dairy cow breeds for intake and milk production, however, the ability to manipulate voluntary cow traffic and milking frequency on AMS farms through breed selection is unknown. This study investigated the effect of breed (Holstein Friesian versus Illawarra) on voluntary cow traffic as determined by gate passes at the Camden AMS research farm dairy facility. Daily data on days in milk, milk yield, gate passes and milking frequency for 158 Holstein Friesian cows and 24 Illawarra cows were collated by month for the 2007 and 2008 years. Illawarra cows had 9% more gate passes/day than Holstein cows over the duration of the study; however, the milking frequency and milk yield of both breeds were similar. Gate passes were greatest for both breeds in early lactation and in the winter (June to August) and summer (December to February) seasons. These findings highlight an opportunity to translate increased voluntary cow movement associated with breed selection into increased milking frequencies, milk production and overall pasture-based AMS performance.

This is the report of sacroiliac luxation in a Holstein-Friesian cow, describing the progression of the sacroiliac luxation from the onset of its development with changes in estradiol (E2) and serum chemistry. The high estrogen concentration was assumed to be a predisposing factor of the disease that relaxed the pelvic muscles and a secondary slippery finally caused the sacroiliac luxation. The E2 was present at levels four times higher in the cow with sacroiliac luxation (167 pg/mL) than in normal cows. Above normal levels of creatinine kinase, aspartate aminotransferase, and lactate dehydrogenase were also observed in cow with sacroiliac luxation.

A 4-year-old Holstein cow with progressive atrophy and ataxia was submitted for diagnosis. The postmortem examination revealed multifocal yellowish nodules in the pulmonary parenchyma and vegetative masses in the mitral and tricuspid valve of the heart. Both kidneys were severely enlarged, with multiple yellow nodules on the parenchyma. Histopathologically, pulmonary abscesses, vegetative endocarditis, suppurative glomerulonephritis, and fibrino-purulent arthritis were observed. The tiny β-hemolytic bacterial colonies were isolated from the lesions and identified as Arcanobacterium haemolyticum by the VITEK 2 system (bioMérieux, USA). This is the first documented report of an A. haemolyticum infection in a Holstein cow in Korea.

In Korea, it is the one of controversial problems to distinguish heifer from cow in slaughtered Holstein cattle. This study was conducted to evaluate the several criterions which could be used to discriminate heifer from cow. Some criterions have shown significant differences between heifer and cow in ante and post-mortem inspections(p<0.01). Firstly, the numbers of milk teeth of heifer and cow were $6.12{\pm}1.92$ ($Mean{\pm}Standard$ deviation) and $0.03{\pm}0.39$ respectively. The teat diameter(D) and length(L) of cow were $26.43{\pm}4.31mm$ and $47.76{\pm}6.89mm$ respectively. However, those of heifer were significantly smaller (D: $18.04{\pm}5.04mm$, L: $28.61{\pm}8.91mm$) than those of cow. The size of udder was $203.68{\pm}16.84mm$ in Holstein cow and $112.70{\pm}20.59mm$ in heifer. Secondly, the uterus size of cow was significantly bigger than that of heifer and caruncle in mucosa of uterus could be easy to be confirmed by necropsy inspection. It was also obvious that the folding and length of uterus body were significantly remarkable in cow. Lastly, the pelvic cavity was $196.33{\pm}10.01mm$ in heifer and $220.90{\pm}11.41mm$ in cow. The ossifying maturation of heifer was $2.64{\pm}0.82$ and $6.71{\pm}1.81$ in cow. As the results, this study can be helpful for meat inspectors to discriminate the non-delivery heifer from delivery cow in Holstein cattle.

The increase in the meat quality and milk production of cows, which breed Korean Native Cow (KNC) and Holstein cow, is not improving reproductive efficiency. In this study, we examined the effect of interferon (IFN) supplementation on motility of frozen-thawed semen and pregnancy rate after artificial insemination of KNC and Holstein cow. In experiment 1, we investigated the effect of IFN-tau concentration (10,000 IU and 20,000 IU) on the percentage of total motility (TM) and progressive motility (PM) of frozen-thawed spermatozoa. In experiment 2, KNC were infused 20,000 IU IFN-tau at insemination or after insemination. In experiment 3, KNC or Holstein cow were inseminated with frozen-thawed semen and infused 20,000 IU IFN-gamma or -tau after insemination. In experiment 1, the average of TM (23.9% to 30.9%) and PM (18.5% to 21.9%) were similar between control and treatments. In experiment 2, the pregnancy rates of IFN infusing times were not different from 45.8% to 53.6%. In experiment 3, the pregnancy rates of Holstein cow infused different kinds of IFN were similar (control, IFN-gamma, IFN-tau; 42.9%, 40.5%, 48.0%). In the case of KNC, however, the pregnancy rate of control was 55.6%, which was significantly lower than that of IFN-gamma (68.9%; p<0.05). Thus, IFN is effective on the improvement of reproductive efficiency, but further study is needed.
