Popis: NO consistent relationship between the dietary protein level and the resistance or susceptibility of the chick to microbial infections has been found. Steffee (1950) observed lowered resistance and increased mortality among protein-depleted birds from pneumococcal infection. Hill and Garren (1961) obtained different results with Salmonella gallinarum infection: increasing the protein level of the diet from 10% to 20% to 30% resulted in a progressively increased rate of mortality. Boyd and Edwards (1963) employed diets with 15% and 30% protein and found that birds receiving the high protein diet suffered lower mortality from E. coli and higher mortality from S. gallinarum and Newcastle disease virus inoculations. Fisher et al. (1964) demonstrated that birds prefed a supernormal protein diet showed greater immunity to and lower mortality from NDV infection. Blood cheimistry changes in the chick following microbial infections have been studied by Dooley et al. (1958), Shelton and Olson (1960), Cole and…
