KEYNOTE SPEAKERS

Professor Warren Burggren (University of Texas)

"Epigenetics and incubation: short- and long-term implications for scientists and practitioners"

Professor Warren Burggren is University Distinguished Research Professor at the University of North Texas and he has published extensively on epigenetics in poultry with emphasis on water balance and kidney function in embryos.

Afternoon of October 4th - Seminar "Hatching egg quality"

contributors

Professor Maureen Bain (Professor of Comparative Anatomy and Histology, Institute of Biodiversity, Animal Health and Comparative Medicine, University of Glasgow)

Professor Bain will discuss hatching egg quality with focus on egg shell in commercial hatching eggs.
 

Marleen Boerjan, Pas Reform Academy,

"Initiation of gastrulation during egg formation in the hen and first day in incubation."

AND

WORKSHOP - "STAGING THE EMBRYO"

led by

Murray R. Bakst PhD.

Consultant, addressing issues in fertility and early embryo mortality.

This workshp is being organized and sponsored by the Aviagen team of Dr Dinah Nicholson, Global Manager of Hatchery Development and Support at Aviagen.

Embryos collected from fresh eggs and eggs that are incubated for short periods during storage (SPIDES) will be shown (large screen presentation) and discussed by Murray Bakst. The collection of blastoderms from fresh eggs will also be demonstrated.
