Abstract

In comparison with artificial insemination with fresh semen or short time stored semen, the results of artificial insemination after cryopreservation are not satisfactorily in poultry. Nevertheless, the interest of commercial breeders in cryopreservation is increasing. An increase in utilization of ...

Abstract

Data on 1048 eggs from hens inseminated at 3- to 4-day intervals over 6 wk (group 1) and 758 eggs from hens inseminated at 7-day intervals over 4 wk (group 2) were analysed. The overall egg fertility and hatchability was 74.5 and 63.0% resp. for hens in group 1 vs. 55.2 and 43.5 in group 2, embryo...

Abstract

Following staining with fluorochrome DAPI (4,6-diamino-2- phenylindol), sperm left on the vitelline membrane of fertilized hen's eggs could be counted by fluorescence microscopy. This count was shown to be correlated with fertilization rates, and with the length of the fertile period (i.e. length...

Abstract

100 hybrid hens were inseminated at intervals of 2-3 days over a period of 4-6 wk with frozen semen diluted with ethylene glycol or dimethylacetamide (DMA). For 1740 and 1411 eggs in the 2 groups resp., egg fertility averaged 55.5 and 64.8%, and hatchability was 70.0 and 81.4% for fertilised eggs...

Abstract

At 22 wk of age, ♂♂ and ♀♀ were transferred from floor pens to cages. For cocks ejaculated 3 and 5 times per wk, ejaculate volume averaged 0.89 and 0.83 ml resp., sperm concentration (spermatocrit value) 12.0 and 12.5%, sperm motility 80.2 and 80.2%, methylene blue reduction time 2.0 and 1.7 min,...

Abstract

The authors' work on the use of the Blumberg poultry semen diluent, containing sodium glutamate, glucose and potassium acetate, is reviewed. After storage of semen diluted 1:1 in the medium for 6 h at 2°-5°C, insemination doses of 0.05 ml resulted in an egg fertility of 92.4% and hatchability of...

Abstract

Fowl semen was diluted with 2 different glutamate-based diluents with 8% glycerol and was frozen in pellets. When the semen was used for shallow, vaginal insemination using 180 × 106 spermatozoa per insemination dose, the overall egg fertility was 19.4% vs. 27.7% for deep, vaginal insemination of...
