title: Effect of dietary protein source and cereal type on the incidence of sudden death syndrome in broiler chickens.
abstract: Three experiments were conducted to compare the incidence of Sudden Death Syndrome (SDS) in male Peterson by Arbor Acre broiler chickens fed diets with either corn or wheat as the grain type and meat meal or soybean meal as the main protein source. In the first two experiments, the broilers were raised in floor pens to 6 wk of age, and in the third experiment they were raised in battery-brooder cages to 4 wk of age. In both floor pen studies, total mortality and the incidence of SDS were significantly higher for wheat-fed birds, while SDS as a percentage of total mortality was not affected by cereal type. In the brooder study, neither total mortality nor mortality from SDS was significantly affected by cereal type. In the floor pen studies, the incidence of SDS as a percentage of the birds housed, was reduced by the inclusion of meat meal in the diet. In the brooder study, total mortality and the incidence of SDS were not affected by protein source, but SDS as a percentage of total mortality was reduced with the inclusion of meat meal in the diet.
