Abstract

Uterine contractions were ultrasonically recorded (t=20 min) in 50 maiden mares (3-4 years old) within 0-6 h after hCG induced ovulation. The mares were divided into 5 groups (n=10, respectively). Group 1 was inseminated conventionally into the uterine body, while Group 2 was inseminated onto the...

Abstract

FOR economic and genetical reasons the application of artificial insemination to goat breeding would be particularly advantageous. The number of bucks could be reduced and numerous separate service stations replaced by a central insemination centre, thus saving time, food, and labour. 20-25% of all ...

A REVIEW of the literature on the technique of collection and storage of sperm, and of insemination, and an account of the methods finally decided upon for use at Pinneberg [cf. Goerttler, A.B.A., 10: 206]. The pH of Milovanov's gluco-phosphate dilutor was modified to 7.2 instead of the original...

Abstract

SINCE 1937 over 600 cows and heifers and 40 mares have been artificially inseminated at the author's clinic.

Abstract

Artificial insemination was carried out on 62 cows and heifers with functional or organic abnormality of the genital organs and 25 became pregnant. In only 30, however, was there certainty that first quality sperm was used, and the follicle not ruptured immediately before insemination. Of these 30...

Abstract

TWENTY-FIVE conceptions (40.3%) resulted from 62 inseminations. Ultimate evaluation of the results, however, could be based on only 30 inseminations in which it was certain (a) that satisfactory sperm was used and (6) that the mature Graafian follicle had not been freed by pressure immediately...

Abstract

LITERATURE is reviewed. According to the author's own studies there is no correlation between the vaginal smears and the sexual stage. The microscopical pictures of vaginal smears did not give any evidence as to the time of onset of oestrus in 8 Karakul ewes as studied in over 650 preparations. 150 ...

EXPERIMENTS were made in a district of Hessen which is seriously affected by Trichomonas infection. Sperm was collected in the artificial vagina and inseminated into 98 cows. 78 were clearly on heat and 72 of them became pregnant; the 20 that did not exhibit heat failed to conceive.
