Abstract

Supporting the rescue of the valuable indigenous domestic animal species is an important part of the new Hungarian agricultural strategy. In the case of poultry species semen cryopreservation is the most practical method for the long term storage of the genetic material. So far, only a single study ...

Abstract

The embryotransfer (ET) is a complex reproductive procedure and it includes several assisted reproductive techniques/technologies (ART) such as superovulation, artificial insemination, embryorecovery, in vitro fertilization, gamete and embryo freezing, in vitro culture, embryotransfer, estrus...

Abstract

The authors examined the ovarian function of Prolific Merino sheep breed by hormone-analytical methods in spring and early summer. Blood plasma progesterone level was measured for following up the ovarian function; examining the reaction of ewes for cycle induction methods, rate of conception and...

Abstract

Both in human and farm animals, assisted reproductive techniques (ART) are used to support the reproductive processes and the formation of fertilization. ART are: artificial insemination (AI), synchronization of oestrous/ovulation+timed AI, synchronization of calving, superovulation and embryo...

Abstract

The authors evaluated the results of the regular pregnancy examinations in a Holstein-Friesian dairy herd during a two-year interval. Pregnancy examinations were carried out by ultrasonography at Days 29 to 42 after insemination. Sensitivity, specificity, positive and negative predictive values of...

Abstract

The aim of this study was to determine the changes in egg size, concentrations of corticosterone in egg yolk and rate of embryonic death following artificial insemination (AI), as a stressor, in domestic hens. 14 hens of the experimental (AI) group were inseminated with fresh, diluted semen (300...

Abstract

The effect of cryopreservation on rabbit spermatozoa was evaluated. The semen of 20 breeding bucks was evaluated with in vitro methods and artificial insemination (AI). It was shown that the recovery rate of cells was higher when the original concentration was lower. Cryopreservation decreased the...
