JOURNAL FREE ACCESSJamshidi's needle was applied to the second or third sternebra of a recumbent cow under local anesthesia without causing noticeable pain. Only pressure was enough to check hemorrhage from the site of application. The collected bone marrow fluid was used to determine the nucleated cell count, megakaryocyte count, myelocrit value, and myelogram. Biopsy with this needle made it possible to collect a tissue sample about 3×2mm in size free from contusion and injury and sufficiently available for microscopy.
This needle was applied to bovine field cases of bracken poisoning. In some of these cases exhibiting a marked decrease in the thrombocyte count, the megakaryocyte count also showed a distinct decrease, but the myelocrit value was not so obviously different from that of the normal cow. The myelogram clearly reflected the histological changes revealed by biopsy. A simultaneous use of bone-marrow fluid and tissue specimens collected by means of Jamshidi's needle for biopsy is useful for making an exact diagnosis and prognosis.View full abstractDownload PDF (8588K) -
II. Colostrum and Pooled Milk Given to Calves for Prevention of DiarrheaYUJI HASHIGUCHI, [in Japanese], [in Japanese], [in Japanese], [in Japa ...1981 Volume 34 Issue 5 Pages 212-216

JOURNAL FREE ACCESSIn the spring of 1978, contagious calf diarrhea occurred in a dairy herd in Hokkaido. It induced severe diarrhea, dehydration, depression, and anorexia. From the beginning 6 calves died one after another. Two agents were isolated from them and identified as Bovine rotavirus and enterotoxigenicEscherichia coli.
Colostrum and pooled milk supplemented with antibiotics were given orally to 8 neonatal calves. As a results, seven calves, which had been born in the early period of the outbreak, were affected with only mild diarrhea. All of them recovered later, except one which died. Four calves born later were not affected at all. Changes in antibody titer against bovine rotavirus were observed in the sera of calves. The antibody titers of pre- and post- sera increased significantly in 4 of the 7 calves. but decreased in the latter 4 calves.
It was concluded that colostrum and pooled milk conferred lactogenic immunity to neonatal calves.View full abstractDownload PDF (1065K) -

JOURNAL FREE ACCESSWhile a Holstein cow was under treatment of foot rot, a neoplasm developed between the hoofs of the right hind limb. It was proved histopathologically to be acanthosis after it had been left untreated for a considerably long time on account of the ignorance of her owner.View full abstractDownload PDF (5568K) -
