Abstract

Cryopreserved boar semen has been commercially available since 1975 but nowadays the use of frozen-thawed sperm in artificial insemination technologies represents around 1% of total inseminations. This limited use is mainly due to the poor reproductive output obtained with frozen-thawed sperm...

Abstract

The fertilizing spermatozoon has to have a series of attributes in order to achieve its goal: acceptable morphology, proper metabolism for energy production, progressive motility, capacity for hyperactive motility, etc. In addition, the genetic package of the fertilizing spermatozoon must contain...

AbstractFull Text

The aim of study was to develop a reliable semen collection and cryopreservation method for gene banking in European wild rabbit (Oryctolagus cuniculus). The animals were kept in cages individually. The bucks were trained for ejaculation into an artificial vagina. The device is hand-held beneath a...

AbstractFull Text

We started to chart the genetic diversity and purity of the Carpathian honeybee substance by using genomic DNA markers. In different families, genotypes of queen bee can be determined by using STR markers and we can choose which the best for long-term ex-situ storage is. We can use the...

AbstractFull Text

Because of several advantages, the artificial insemination (AI) becomes an important method of the practice of rabbit breeding. Usually, the breeders use fresh or cooled semen for insemination, but in some special cases cryopreserved semen is applied. It is possible to create a gamete bank for ex...

Abstract

Establishing a sperm bank for the ex situ genetic conservation of European Wild rabbit (Oryctolagus cuniculus) is in progress. For the success of forthcoming artificial insemination programs, it is important to provide good quality semen samples conserved by cryopreservation. We work on developing...

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

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

In Hungary, there were 1100-1200 stallions, which were enough to cover the insemination of the country's mare stock. The ownership relation of the stallions changed. Private ownership increased from 25 to 56%. Besides the increase in the number of the stallions, the proportion of cold-blooded and...
