Effect of protein starvation on protein turnover in liver, oviduct and whole body of laying hens.
1. Whole body protein turnover rates in White Leghorn laying hens were reduced by protein starvation for 7 days, followed by complete restoration by protein repletion for 7 days. 2. Protein starvation considerably reduced fractional and absolute rates of protein synthesis both in the liver and, to a greater extent, in the oviduct. 3. It was suggested that a considerable portion of the reduced whole body protein synthesis could be accounted for by the reduced protein synthesis in these organs when laying hens were subjected to protein starvation.
