Dl4—Lancaster Farming, Saturday, September 1,1984 BY JACK RUBLEY LANCASTER - Mike Midgley first learned of the benefits of intermittent lighting for poultry production four years ago during a visit to New York’s Cornell University. Returning home to his native England, the manager of a 1.5- million-bird layer flock decided to test the principle. Midgely soon found not only a decrease in feed and light bills, but an increase in egg size, as well. Such savings are vital to Great Britain’s egg producers, who, according to Midgley, pay the equivalent of $202 per ton for feed. According to Bill Markey, manager of the poultry division of Keystone Mills in Ephrata, decreasing the duration while at the same time increasing the Dutch elm film available HARRamUE N.H. -a. ffpSt SfW Research Institute is proud to “cancer of the tree world” under introduce its newest tool for saving control for the f irst time. elms - a twenty minute film Viewing the American elm demonstrating the current state of through the eyes of the renewed the art in prevenfave treatment for H enry David Thoreau, “Preser- Dutch ehn disease. vmg a Heritage - The American The film uses sound and color in Elm .. a persuasive case for Presentation of the the survival and replanting of the i e^id^ Se r ° m lt f most beloved of all shade trees.

Since birds eat less at a time, but more frequently, their digestive systems assimilate food more completely and ef ficiently. And since the total duration of darkness is increased, birds use less energy.
