Immersion heat treatments for inactivation of Salmonella enteritidis with intact eggs.

The effects of water-bath immersion heat treatments on the inactivation of Salmonella enteritidis within intact shell eggs were evaluated. Six pooled strains of Salm. enteritidis (ca 3 x 10(8) cfu, inoculated near the centre of the yolk) were completely inactivated within 50-57.

Introduction to egg pasteurization.

The science of microbiology is very young in comparison with the age of mankind. Related developments in the area of pasteurization have been made during the past 131 yr. This symposium reveals some recent advancements in pasteurization of shell eggs and egg products.

Dates and date pits as ingredients in broiler starting and coturnix quail breeder diets.

Two broiler growth and two quail breeder studies were conducted to evaluate the dietary potential of dates, date meat, and date pits. The test ingredients were incorporated in broiler starting diets at levels ranging from 8 to 43% dates, 16 to 43% date meat, and 5 to 27% date pits. The quail breeder diet had ingredient ranges of 10 to 30% dates, 8 to 24% date meat, and 5 to 15% date pits.

Effect of inorganic phosphate source and dietary phosphorus level on laying hen performance and eggshell quality.

Two experiments were conducted to evaluate laying hen performance when fed two sources of inorganic phosphorus. In Experiment 1, a regular and a coarse form of defluorinated phosphate and one source of dicalcium phosphate were used in diets calculated to contain either .4 or .

Influence of wet and dry feed on laying hens under heat stress.

Two experiments were carried out with a split-plot design over time using White Leghorn hens, 161 days of age. The experiments were conducted to determine the effect of two ambient temperatures (21.1 versus 29.
