The Effects Of Varying Dietary Protein, Calcium And Phosphorus In Starter Diets For Early Weaned Pigs, Wayne Eldon Schiefelbein

Electronic Theses and Dissertations

Genetic selection by swine producers the past 10 to 15 years has resulted in faster growing, heavier muscled pig. In addition, confinement rearing has placed an increased emphasis upon skeletal development and bone formation. Recent research conducted at Ohio State University indicated that growing swine responded to increasing dietary protein levels if both calcium and phosphorus are also correspondingly increased but maintained at approximately a 1.3:1 ratio. This and other research has led some investigators to believe that the National Research Council's requirements for protein, calcium and phosphorus may not be adequate to support maximum growth and development. Much attention …
