The enormous expansion of A. I. in recent years in the German Democratic Republic (1, 446, 483 first inseminations in 1958) has made pregnancy diagnosis by veterinarians impossible. A method of assessing A. I. results other than the non-return method is proposed, called " herd analysis ". This...

Abstract

THE author is of the opinion that the use of biological methods of pregnancy diagnosis provides evidence for incompetence. Although direct vaginal inspection is not considered to be detrimental, the rectal method is preferable, and an experienced observer should be able to diagnose a 6-weeks'...

Abstract

I & II. Sterility in mares is generally the result of metritis. In the study of the onset of urogenital disorder, it is essential to differentiate between early symptoms of disease and of oestrum. The appearance of the genital tract during oestrum is described. When infection is suspected, it is...
