[Winter diarrhea].

Winter dysentery is a highly contagious, herd-enzootic disease of cattle, most frequently observed during the winter season. The disease is characterized by a sudden onset of severe diarrhoea, which normally disappears spontaneously within two or three days. The aetiology continues to be obscure, though a virus is a probable causative agent.

Changes of serum enzyme activities in cows with milk fat depression.

Serum activities of sorbitol dehydrogenase (SDH), lactate dehydrogenase (LDH), gamma-glutamyltranspeptidase (gamma-GT), and alkaline phosphatase (ALP) were measured before, during, and after milk fat depression in 9 cows fed a high-concentrate ration during 2 experiments. In 7 of the 9 cows, increases in serum SDH and LDH activities were observed during milk fat depression. The gamma-GT activity showed only moderate changes, whereas the ALP activity remained unchanged. During recovery from milk fat depression, decreases of SDH, LDH, and gamma-GT activities were found in nearly all cows. Association of this phenomenon with changes found in beef cattle, such as ruminal lesions and liver abscesses, are discussed.

[Results of treatment by rotation in left-sided abomasal displacement (author's transl)].

The results are given of the treatment of thirty cows with left-sided abomasal displacement by rotation, followed by intravenous injection of hypertonic sodium chloride solution and a calcium borogluconate solution. In addition, ammonium chloride was administered orally for a few days. The rations of the animals were gradually restored to normal levels. The purpose was to examine whether recurrences following rotation could be prevented by supplementary measures. Of these thirty animals, five did not respond to treatment because of complications that would otherwise not have reacted favourably to any form of treatment either. Correction of the abomasal displacement was successful in more than 90 per cent (23 animals) of the remaining five cows. However, abomasal displacement recurred in sixteen of these twenty-three animals (70%). Of these fourteen cows, two animals developed an abomasal torsion. It is concluded that the supplementary measures adopted will not prevent recurrences.

[Arsenic poisoning through the roof. A case of arsenic poisoning in cattle].

A case of arsenic poisoning in cattle is reported, in which six out of fifteen animals died. The source of poisoning was traced to a substance in the loft of the hay-barn, which probably consisted of the remains of a pesticide which had been there for several years. This had become liquefied as the result of a leak in the roof and had found its way into the hay. The arsenic content of the substance ranged from 17 to 37 per cent, that of the hay being up to 0.3 per cent. The concentration of arsenic in the organs, blood, faeces and urine of the animals were indicative of poisoning. The main clinical findings consisted in profuse diarrhoea, loss of appetite, muscular weakness and an ataxic gait. Dehydration set in later and the animals became deeply soporous. Symptomatic treatment was mainly directed against dehydration, hypoglycaemia and hypocalcaemia. The greater part of the animals gradually recovered. Marked hyperaemia of the abomasal mucosa and, to a less extent, hyperaemia of the small and large intestines was observed on post-mortem examination.

[A cow showing abnormal distension of the abdomen: omental bursitis (author's transl)].

A highly uncommon clinical picture in a cow showing abnormal distension of the abdomen as the most important clinical symptom, is described. The anatomy of the bovine adbomen is briefly reviewed, particular attention being paid to the omental bursa. This is followed by a discussion of the history and clinical symptoms. The owner complained of the fact that the cow showed loss of appetite and abnormal distension of the abdomen. The most important finding on clinical examination was made on rectal exploration, in which a large sac filled with fluid was felt in the abdomen. Exploratory laparatomy showed that this was an inflamed omental bursa containing a large quantity of serofibrinous exudate. This diagnosis was verified by pathological studies. The discussion is concerned with the differential diagnosis and a comparison is made with a number of similar cases reported in the literature.

[Traumatic pericarditis, an old acquaintance in due form (author's transl)].

The clinical, radiographic and post-mortem studies in an 18-month-old heifer are reviewed. The complaint was that the animal had not been eating and drinking for as long as ten days. Clinical studies revealed obvious changes of the respiratory and circulatory systems: marked engorgement of the jugular veins, clapotement synchronous with the heart beat and bronchial respiration over the apical lobes. Clinical examination was followed by a differential diagnosis in which traumatic pericarditis, pleurisy and an intrathoracic abscess were mainly considered, and is was decided to carry out radiography. The X-rays showed a major lesion, within which a horizontal level was observed. In addition, a large foreign body was discernible. The animal died within a few days and the diagnosis of traumatic pericarditis was verified, though pleurisy was also found to be present. The ichorous splenitis revealed by the post-mortem studies was not observed on clinical examination. The difficulties involved in arriving at a correct differentiation between pericarditis, pleuristy and an abcess are discussed in retrospect.
