Abstract

The frequency of insemination in hens affects the costs associated with artificial insemination in poultry. A reduced frequency implies a larger insemination interval and therefore a reduction in costs. The objective of the study was therefore to assess the effect of insemination intervals on...

Abstract

Following artificial insemination, the egg-laying rate of a large-scale breeder chicken flock declined by 10-15%. Real-time quantitative polymerase chain reaction (qPCR) analysis detected the presence of reticuloendotheliosis virus (REV) in semen from the breeder cocks used. Six REV strains were...
