Optimal calcium supply for laying hens
Keywords Calcium supply, laying hens, egg quality, shell strength, health, welfare Co-Authors H.-H. Thiele, G. Díaz (Biomix S.A.) and L. Armel Ramirez (Pronavicola S.A.) Laying hens produce a lot of eggs as hatching eggs or shell eggs for human consumption. Good quality eggs with strong shells ensure farm income and meet the demands of hatcheries, […]

Pioneering in the implementation of genomic information in fish breeding
Co-Authors A. Storset, T. Moen, J. Ødegård and Nina Santi AquaGen AS, Trondheim, Norway AquaGen was the first fish breeding company to implement marker-assisted selection directly in salmon egg production (2009), enabling rapid transfer of improved genetic material to salmon producers. The company is still a leader in the implementation of genomic information. In 2014 […]

Free-range egg production in Australia – industry trends and challenges
Abstract In Australia, free-range egg production is a rapidly growing sector with an estimated grocery market value share of 48% of total table egg production. It can be estimated that around 200 commercial free-range egg producers are currently active. This report reflects the current situation these farmers are facing. Adverse climate conditions and Avian Influenza […]

Risks of spoilage and Salmonella contamination of table eggs
Abstract Consumers and food business operators are more and more aware of food safety issues. Food safety can broadly be divided into microbiological and chemical food safety. Microbiological contamination of eggs has important implications. For table eggs, internal contamination may occur, leading to spoilage and in the case of a pathogen to human disease and […]

Economics of Dual-Purpose Breeds
Abstract The use of Dual Purpose Breeds (DPB) is considered a strategy to avoid killing of day-old male chicks of layer lines. Since these males grow slowly and have a poor feed conversion rate, DPB have been developed by commercial breeding companies. Despite better growth rate of DPB males the production cost of these birds […]

Management of Pullets and Laying Hens under Tropical Conditions
Abstract Environmental temperatures play a major role in the optimal rearing of layer pullets, the basis of a financially successful production period of the layer bird. The optimal temperature for a white layer is 23 degrees celcius, respectively 24 degrees for brown layers. Every degree Celsius above this level will cause reduced feed intake and […]

Avian Influenza Outbreaks in the USA in 2014 and 2015
Abstract Outbreaks of Avian Influenza (AI) in the USA from 2014 onwards affected 42.1 million layers and pullets as well as 7.5 million turkeys. From a special analysis of the outbreaks it becomes obvious that migrating birds played an important role in spreading the disease throughout Northern America. Depopulation, transport and deposition of the dead […]
