The diagnosis of necrotizing enteritis in infant piglets is based on clinical observations, patho-anatomical changes, and bacteriological and bacterio-toxicological examinations.
Necrotizing infectious enteritis provoked by CI. perfringens type C has been diagnosed with increasing frequency among piglets in Danish herds since 1963.
The aim of the investigation was to establish whether blood samples collected at slaughter are of diagnostic value.

Changes in mammary blood flow and the weight of udder occurring about the time of parturition in goats have been reported by Linzell (1960, 1966a, b) and Reynolds (1965). The present paper now gives the results o...
For the examination of changes in the mammary blood flow in cows during the lactation period it is desirable to relate the blood flow to milk yield as well as to udder weight. Therefore, a method is required w...
A hypochromic microcytic iron deficiency anemia associated with light underfur and increased mortality in mink kits is caused by the feeding of various species of raw marine fish, especially coalfish (Gadus vi...
When butyric acid was injected intravenously at an amount of 2.5 mM/kg, blood glucose rose markedly in normal sheep. In a ewe with pregnancy toxemia blood glucose did not change. When the same amount was injec...
Autopsy studies of the thyroid gland in lactating cattle were combined with chemical tests of thyroid function, i.e. protein-bound iodine (PBI) in serum, and uptake by the erythrocytes in vitro of I131-labelled L...
The haematological effects (Hb, RBC, PCV, Price-Jones curve, MGV, MGHG and Heinz body counts) of feeding lambs on marrow-stem kale were followed and the results evaluated statistically.
After a review of the literature the report of a trial with 30 dairy cows is presented. The cows were divided into 3 groups of 10; 1 group functioned as control (A), 1 had free access to marrow-stem kale (B), ...
The clinical and pathological details of a case of ataxia in a 3-month-old colt are described. A marked protrusion into the vertebral canal of the body of the 3rd cervical vertebra was observed. C3 and C2 were im...
Number of platelets, leucocytes and packed red cell volume (PGV) have been determined in normal piglets during the first 2 weeks of life.
After peroral administration of 10 % NaHCO3 solution + glucose the rise in blood sugar was greater than after glucose alone. This indicates that the oesophageal groove reflex can be released also in adult cattle....
Cases have been described of fatal nitrite poisoning in swine resulting from the intake of condensation water from ventilating shafts (Andersen 1962, Olsson & Rösberg 1964).
A gas chromatographic method is described by which 11 amino acids in protein hydrolysate can be determined. They are: alanine, aspartic acid, glutamic acid, glycine, isoleucine, leucine, lysine, methionine, ph...
Altogether 8 strains of aeromonads were isolated from various furred animals; 2 of the strains may have had fatal significance. The investigations showed that the identification of these bacteria can be based ...
Inoculation experiments were performed with two German strains of swine fever virus. In Experiment I, ten pigs of Danish Landrace were inoculated with a strongly virulent strain, while in Experiment II ten pig...
Using a radiopaque contrast medium and a local anaesthetic injected epidurally in 70 young pigs, measuring 40—100 cm in length and weighing 6—65 kg, it was investigated how far foreward the anaesthetic penetra...
Pulmonary lesions associated with Pseudomonas infections in mink were studied histologically. In peracute cases the injury consisted of hemorrhagic necrosis of the lung tissue. In later stages of progression t...
In order to study some effects of a new haematinic for treatment of piglet anaemia, some basic studies on untreated animals have been performed. It has been shown that during the first weeks of their life, the...
