In May 1956 a 31/2 year old male poodle took ill showing symptoms of meningitis which seemingly involved the base of the brain. Five days later the animal had completely recovered from the acute illness and he...
The feeding of cane sugar in excess to sheep maintained on a hay diet led to indigestion with marked changes in the microbial population, pH and physical properties of the rumen fluid.
1) In an active rumen fluid 37.6—73.1 per cent digitalis is inactivated in 48 hours in vitro.
Endogenous creatinine and urea clearances have been studied in 12 mares simultaneously with inulin clearance at a constant plasma level of inulin. The following values were found, calculated per 100 kg. body w...
The Purkinje cells in the cerebellum of some domestic animals were investigated by using various staining methods, especially the aldehyde-fuchsin method. The cells were rich in acid and alkaline phosphatase. ...
The changes in the sternal bone marrow in connection with normal parturition were studied in 18 cows 13 of which were punctured before as well as after parturition. The bone marrow of cows with parturient pare...
By means of chromatographic and spectrophotometric methods the presence of oestrone in the urine from sows in late pregnancy has been demonstrated.
The nerve supply of the knee joint in cattle was studied by dissections on sucking-calves and by nerve staining of section series of foetal joints.
The literature on early embryonic mortality in cattle is outlined as well as communications on the fertility-decreasing and oestrusinterval-prolonging effect of the Vibrio fetus infection.
The present paper is the continuation of a previously published work, (Havre & al., 1960), on the study on conditioned and simple copper deficiency in cattle and sheep in Setesdalen, a valley in the South of Norw...
Streptococci, lactobacilli and yeasts have been isolated from the dominating Gram-positive flora developing in the rumen of sheep during feeding experiments with sucrose, lactose and starch.
Determination of phosphorus, magnesium and pH was done on blood serum from normal cows in the non-calving period, from normal cows a few days after calving, and from cows with parturient paresis. The following...
Determination of total calcium and free calcium ions, determination of total protein and paper-electrophoretic fractionation of the protein were done on blood serum from cows, in the non-calving period, a few ...
Every other animal in a herd was treated with staphylococcal toxoid for 3 years. In the herd there occurred a relatively great number of cases of staphylococcal mastitis. The treatment of already infected cows...
With a slightly modified immunoelectrophoretic technique (lactate-buffer, 1 % agar gel) 37 sera from pigs of the Danish Landrace are investigated as regards specific variations. The investigations show that it...
