Abstract

Genomic selection is a highly innovative tool that expanded rapidly in today's dairy cattle breeding programmes. The proportion of inseminations with genomic proven bulls increased steadily but large regional differences can be observed. The superiority of such bulls is evident for all traits which ...

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

The present study aimed to improve semen processing to satisfy the demands of a DIN ISO-Standard and to present the introduction of a Quality-management System, which satisfies the requirements of the standards DIN EN ISO 9000ff on an artificial insemination station. Average semen density detected...

Abstract

Ovulation induction is recommended on the 3rd day of oestrus when the follicle has a diameter of ≥40 mm. Administration of 1500 IU HCG combined with insemination 24 h later with chilled semen is recommended. The intensity of the endometrial reaction depends on the method of semen preservation...

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...

Zur künstlichen Besamung beim Huhn unter Verwendung von Tiefgefriersperma und der intravaginalen Besamungstechnik., 1985, pp 136pp.
Abstract

The method of preparing and freezing the high-density semen fraction in 2-ml pellets is described. Only ejaculates with a sperm concentration of more than or equal to 800 000/ml were used. Pellets were stored in liquid nitrogen for 1-6 mth. Thawing was either by the dry method or in a thawing...

Abstract

The 60- to 90-day NR rate for 6966 inseminations into the cervix was 66.0% v 66.9 for 6447 inseminations into the uterus. The difference was non-significant. Overall, semen from 176 bulls was used. Of 34 bulls whose semen was used for more than or equal to 50 inseminations, the difference in NR...

Abstract

In May-July, semen was obtained twice weekly from 5 male turkeys. Undiluted semen was stored for 30 min. at 22 deg C, was diluted 1:3 with a fructose-yolk-glycerol diluent, placed in medium-sized straws, cooled to 5 deg in 3 h, and frozen in liquid nitrogen vapour. The semen was thawed at 37 deg...

Abstract

When pooled semen from 40 males was diluted 1:1 in a solution containing 7.5% ethylene glycol, sperm motility averaged 71.0% v 81.1 for undiluted semen, egg fertility percentage 57.3 v 66.7, and the hatchability percentage of fertile eggs 77.8 v 78.6. Samples frozen to various temps. from -2 deg to ...
