Prof. Songül Yalçin

Poultry Eggs and Child Health - a Review is based on a paper Prof. Songül Yalçin presented in 2011 at the EggMeat Symposium in Leipzig, Germany, and was updated with her co-author Prof. Suzan Yalçin for this issue. The authors have accumulated an impressive number of references, details of which may be obtained from the authors. The information based on medical literature confirms that eggs contain many nutrients which are essential for balanced nutrition of pregnant mothers, newborn babies and children through school age.

Dr. Dagmar Kapell

a review by Dr. Dagmar Kapell, member of the Aviagen R&D Team. Sound legs have been on the agenda of primary breeders for many years. The author describes how the effectiveness of selection has been systematically improved. Broad breeding goals and appropriate selection indices assure simultaneous progress in all important traits, despite negative genetic correlations. Selection in a highly bio-secure environment was shown to be effective also at the commercial level in the global broiler industry.

Hagen Müller

by Hagen Müller. Broiler growers in Germany and other countries have learned over the years to keep up with genetic changes in growth potential and feed efficiency, while consumers are getting more concerned about production conditions and drug residues. In this paper the author pinpoints some of the mistakes encountered in practice and shows how optimal chick management can improve performance, minimize treatments and regain consumer support.

Robert Schulte-Drüggelte, Dr. Hans-Heinrich Thiele

Using general mathematical techniques described by Kühne and Flock 25 years ago, the authors Robert Schulte-Drüggelte und Dr. Hans-Heinrich Thiele, members of the “Global Competence Team” of Lohmann Tierzucht, review the effect of length of laying period on annual egg income under current conditions of production. Calculations based on production standards for LSL Lite hens in North America and U.S. prices for pullets, feed and eggs show an advantage of about 1 U.S. $ per hen place per year for single cycle flocks kept to 85 weeks compared to molting and a second cycle to 109 weeks of age.

Prof. Holger Martens

by Prof. Holger Martens, Physiologist at the Free University Berlin, who has developed a special interest in the conflict between maximum milk yield and longevity in dairy cattle breeding. With his co-author Christian Bange, he reports observations from a family farm in Northern Germany with a herd of 145 German Holstein cows as an example that negative correlations can be overcome successfully – if management is focused on health and wellbeing of the herd and pays more attention to lifetime rather than first lactation milk yield.

Prof. Dr. med.vet. Dr. h.c. Erhard F. Kaleta

Prof. Dr. med.vet. Dr. h.c. Erhard F. Kaleta worked all his life with poultry and just published a book in two volumes, describing the history of Poultry Medicine at the University of Gießen (ISBN: 978-3-8359-5994-1) and Research on Poultry Diseases (ISBN: 978-3-8359-5995-8), which are recommended for German speaking readers. The paper DISINFECTION IN POULTRY MEDICINE – AIMS AND MEANS should be of general interest for people working with poultry.

Dr. Murdo MacLeod

Dr. Murdo MacLeod, University of Edinburgh, Scotland, well-known as nutritionist and past editor of British Poultry Science, takes a critical look at NUTRITION-RELATED OPPORTUNITIES AND CHALLENGES OF ALTERNATIVE POULTRY PRODUCTION SYSTEMS, reviewing advantages and disadvantages of alternative systems and suggesting answers to current conflicts between limitations for organic production and sustainable use of resources.

Dr. Dinah Nicholson

Dr. Dinah Nicholson et al., Aviagen Ltd., summarize the results of a series of designed experiments to improve hatchability after prolonged storage by application of SHORT PERIODS OF INCUBATION DURING EGG STORAGE – SPIDES. The technique essentially simulates what a broody hen does while adding an egg to her clutch every day.

Dr. Klaus Damme, Stefanie Urselmans

Dr. Klaus Damme and Stefanie Urselmans, Kitzingen, Germany, address a „hot topic“ in European poultry welfare, based on recent experimental results, in their article INFRARED BEAK TREATMENT – A TEMPORARY SOLUTION? Although the message seems clear, the question remains whether public opinion and political decisions in Germany will be impressed by these research results.
