Effect of several dermatitis preventing agents on foot pad dermatitis in dwarf and normal sized single comb white Leghorn layers.
Studies were conducted to determine the effects of increased dietary levels of vitamin and trace mineral mixtures, methionine, meat and bone meal, fish meal, and safflower oil on foot pad dermatitis in dwarf and normal size Single Comb White Leghorn layers. All layers were maintained in individual wire cages throughout a 40-week experiment period. Individual birds were scored for the incidence of foot pad dermatitis and production parameters were recorded. No significant decrease in the incidence of dermatitis was observed from the following dietary supplements: a 50% increase in a vitamin or a complete trace mineral mixture; a 50% increase in an iron, copper, iodine, and cobalt or a manganese and zinc mixture; .05% methionine; 5% meat and bone meal; 3% herring fish meal; or 2% safflower oil. It was concluded that these mixtures or supplements containing such dermatitis preventative agents as pantothenic acid, zinc, and linoleic acid appeared without effect in minimizing expression of the condition in dwarfs.[1]References
