The distribution and elimination of two phenoxyacetic acids, 2,4-D and 2,4,5-T, were studied with a chemical method in rats, pigs, calves and chickens.
The excretion of Se75 via the feces and urine was studied in 30 sheep. Se75-sodium selenite was injected subcutaneously, using three different doses ranging from a tracer dose to a therapeutic dose. By the intrar...
By means of isoimmunizations and heteroimmunizations 10 equine blood typing reagents were isolated. The specific antibodies were complete agglutinins, which were used in the direct agglutination test in saline...
In milk samples from 1520 heifers and 542 dams the αsl-, β- and x-casein types and the β-lactoglobulin components, A and B, were determined simultaneously by means of electrophoresis in thin starchurea-gels.
By means of gas chromatography the authors have found changes in the composition of the milk fat in ketosis and after fasting, the concentration of short-chain fatty acids falling and of long-chain rising. Thi...
The authors compared the thyroid function of cows with primary ketosis and clinically healthy cows in the same stage of lactation by a method based on the in vitro erythrocyte uptake of L-3,5,3′- triiodothyronine...
Microspectrophotometric, microinterferometric and microplanimetric techniques were used to determine the DNA content, the total dry mass and the optical area of morphologically normal ejaculated spermatozoal h...
The immobilization of fractures of the long bones in large animals after transfixation with fibre-glass re-inforced plastic bandages depends to a large extent on the method of forming the pins used to transfix...
Fifteen calves were divided by body-weight into three groups of 5 animals in each. One of the calves was found after slaughter to have had purulent gonitis and was therefore excluded from the study. One group,...
Microspectrophotometric, microinterferometric and microplanimetric techniques were used to investigate whether the maturation of bull spermatozoa is associated with any detectable changes in the major chemical...
The correlation between body growth and linoleic acid in subcutaneous, perirenal and coronary fat and in skeletal muscle and liver fat of pigs was examined. The pigs were killed at about 2 weeks’ intervals whe...
In part A of the investigation the heat resistance of isolated Diphyllobothrium plerocercoids was determined. Treatments for 5 min/at 56°C, 10 min. at 50°C, 20 min. at 48°C, and 30 min. at 47°C were found to b...
