NASA satellite to map gypsy moth UNIVERSITY PARK - NASA’s earth-scanning satellite, passing over Pennsylvania this summer, will chart the defoliation of forests by gypsy moths. The new space age technique will combine computer analysis with in- V'-* Computer-printed map of Perry County, from 1981 Landsat data shows forests defoliated by gypsy moths in black areas with undefoliated forests in white. Gray areas are lands not covered by forests. ALKA-CULTURE™ or ALKA II Dairymen are challenged to develop feeding systems to capitalize on the high genetic ability of today's dairy cows. These systems include the use of high-moisture, fermented feeds, high-moisture, high-energy grains, and high-energy dry grain rations. These types of rations will pro duce more acid than cows can neutralize naturally. This increased acid production results in a lowering of rumen pH -- acidosis. Without adequate buffering, cows may eat less and use feed less efficiently. As a result, production can suffer.
