Abstract

Currently most breeds and lines of geese in use at a commercial scale are derived from two wild species; the swan goose (Anser cygnoides L.) and the true goose-greylag (Anser anser L.). Interestingly, local selections performed for centuries from these two ancestors have resulted in strains or...

Abstract

Over three breeding seasons on a farm in Poland, semen was collected from 11 ostriches using the dummy and the teaser method to study the effects of the method of collection, male age, month in the breeding season, and daily collection frequency on ejaculate characteristics. A total of 259...

Abstract

The experiment was conducted on 16 drakes, 8 from each of two Polish duck conservation flocks: crossbreds of Khaki Campbell ducks with Orpington fauve (KhO-01) and Miniducks (K2), developed by crossing low weight Pekin ducks with wild Mallard. The aim of the study was to determine and compare the...

Abstract

This work focused on inexpensive methods of evaluation fowl sperm morphology, based on eosin-nigrosin smears, which can determine disorders in spermatogenesis and can be recommended for evaluating the fertilising potency and selecting males in flocks reproduced by artificial insemination. Four fowl ...

Abstract

The purpose of the present experiment was to determine the effects of the freezing process on fresh semen quality and spermatozoa susceptibility to cryoinjury stress, evaluated in four subsequent generations obtained after geese insemination with thawed semen. The experiments were carried out on 2- ...
