Compositional and Metabolic Evaluation of Colostrum Preserved by Four Methods During Warm Ambient Temperatures
A study of giant Canada geese (Branta Canadensis maxima) nesting on stock ponds in western South Dakota was conducted during 1974 and 1975. Analysis of 10 selected variables at nests on natural sites indicated that distance of water below high water level and percent slope from wetland to horizon, c...
