Water’s effect on egg performance studied

Don Bell, poultry specialist emeritus of the University of California-Riverside, has recently published his analysis of water consumption on performance and profit in the egg industry.
The effort compared 11 participating companies with 160 flocks comprising 17.5 million laying hens hatched between 2002 and 2005. Data relating to water intake were tabulated to determine how water consumption impacted hen day production, egg mass, egg weight, mortality and feed consumption.
Water consumption was weakly correlated with egg mass to egg weight and to feed consumption. There was no apparent correlation between water consumption and mortality or hen-day production.

Study explores viability of avian influenza in water

A recent article from scientists at the University of Georgia investigated the survival of avian influenza virus in water.
Viability is affected by pH, but with values of 7.4 to 8.2 supporting survival. A low temperature (approximately 50 F) and low to moderate salinity also extended the time over which viruses retained infectivity. The results of this study are important in understanding the transmission of avian influenza from free living water fowl to commercial flocks.
