Sodium selenite was mixed in a commercial pig food so as to increase the original selenium content (0.126 ppm) by 1.2 ppm. The supplemented food was given to 7 pigs during 78 days. A control group of as many p...
Compared to normal pregnancy an evident reduction of the electrical potentials and electrochemical gradients was found in cases of hydrallantois without primary foetal deformity. The permeability of chorio-all...
The concentrations of sodium, potassium, chloride and creatinine in allantoic fluid have been investigated in normal cows and in cases of hydrallantois. After three months of pregnancy the ion concentrations i...
