Peter chrystal

Sydney University

Peter completed his Bachelor of Science in South Africa under Professor Rob Gous and is currently completing a PhD in poultry nutrition at the University of Sydney, investigating reduced protein diets in broiler chickens. Peter has extensive commercial experience in both monogastric feeds and vitamin and trace mineral premix manufacture. He has worked as a nutritionist for the largest poultry integrators in South Africa, New Zealand and Australia, where he currently works for Baiada Poultry, based in Sydney.
