Ten strains of H. pleuropneumoniae isolated from 10 herd outbreaks of pleuropneumonia were studied by means of the slide agglutination test, the indirect haemaggluitiniation (IHA) test and by gel diffusion. Th...
Four adult Norwegian Red cows were employed in an experiment designed to study the kinetics of lactose. The cows were given 50 g or 60 g of lactose by rapid intravenous injection of a 10 % lactose solution. Bl...
Ketosis data from the Health Card System, and interview data regarding feeding, housing, management and care were the basis for an epidemiological study in 306 Norwegian dairy herds.
Data for incidence of summer mastitis in 14 veterinary practices in Jutland (Denmark) were related to meteorological factors using statistical methods. A correlation and regression analysis showed that summer ...
A nasal, so called ethmoidal, tumor from a fallow deer is described. It appears to be the first reported case of that species. The etiology is discussed.
Primary isolates of Vibrio anguillarum-like organisms could be separated into typical V. anguillarum (VA) and atypical V. anguillarum (AVA) by biochemical tests. The prevalence of the fish pathogenic V. anguil...
The object of this investigation was to study the feasibility of using a “Zyklomat roller peristaltic pump” for pulsatile administration of gonadotropin releasing hormone (Gn-RH) in primiparous lactating sows....
The purpose of this survey was to evaluate the reproductive performance of dairy cows on problem farms in southern Iceland. In all 229 cows on 6 farms were studied. The animals were examined clinically by rect...
This paper describes 3 experiments comparing the effect of 10, 25 and 40 mg Se/kg, as sodium selenite, in mineral mixtures and salt licks fed to sheep. The supplement was given during the indoor season from Oc...
An inexpensive and easily automated flow injection method for determination of urea in cow’s milk was evaluated. Urea is hydrolysed by urease and in a gas diffusion cell the ammonia formed passes a membrane in...
Eight heifers were artificially inseminated in the uterine body with 160×106 spermatozoa frozen in French mini-straws. The heifers were slaughtered 2 (n = 4) or 12 (n = 4) h after insemination and spermatozoa wer...
Toxic extracts of the blue-green alga Oscillatoria agardhii were tested for their effect on various isolated laboratory animal preparations. The Oscillatoria-toxins did not show hemagglutinative or hemolytical...
Extracts of the blue-green alga Oscillatoria agardhii were tested for acute toxicity on laboratory mice and rats. Material originating from lake Gjersjøen proved to be toxic to the animals, samples from the ne...
The clinical effect, residues in milk and toxicological properties of a non-commercial formulation of malathion used as an ectoparasitic agent on cattle were investigated. The results show that the malathion p...
The earliest sign of osteoarthritis is acute synovitis with joint effusion and elevated intraarticular pressure, which causes compression of the intracapsular vein segments draining the epiphyseal bone compart...
The oxygen supply to the joint cartilage depends on the oxygen transport from the capsular arteries to the capillaries, the oxygen diffusion across the synovial membrane and the oxygen transport through the sy...
Based on an experimental model of osteoarthritis in 42 full-grown rabbits the histological changes were studied during the development of osteoarthritis after operative induction of instability of the knee joi...
