Abstract:

A novel method for determining air cell location, embryo development, and eggshell defects in opaque thickshelled eggs was tested. Results demonstrated that a camcorder with IR "Night Shot" function performed significantly better (P < 0.05) than unaided visual determination of air cell location in Emu eggs. In addition, the Mini DVC camcorder unit was as accurate as the heavier, non-portable, and more expensive traditional IR candling units. Commercial ratite producers, waterfowl biologists, and others working with opaque thickshelled eggs may benefit from this research.

More about this publication?
  • Avian Biology Research, formerly Avian & Poultry Biology Reviews, has adopted a new and exciting vision for publication of ornithological research in the 21st Century.

    This vision is based on two main concepts. First, the topics published by the journal will cover all aspects of ornithology. This will provide a forum for scientists to publish their work in a journal that will have a broad appeal. Second, the scope of the journal will expand to include reports of original research, letters, perspectives, news, diary and book reviews in addition to reviews. By considering a wide range of research fields for publication, Avian Biology Research provides a forum for people working in every field of ornithology.
