Nutrition and Biochemistry of Survival during Newcastle Disease Virus Infection: Diurnal Changes in Protein, Nucleic and Free Amino-acids of Avian Liver

Abstract

SINCE intracellular exchange of nutrients is extremely rapid, research in this area is basic to the further understanding of biochemical changes in tissues of chicks subjected to virus infection. Earlier reports from these laboratories have covered the incubation (0–72 h post-inoculation) and active involvement stages (72–144 h) of a Newcastle disease virus (NDV) infection in chicks^1–3. The investigations have shown that composition and intake of diet, clinical symptoms, and stage of the disease cycle may significantly affect the liver protein, deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and free amino-acids of infected chicks.
