Extension and Experiment Station Publications
It can be very challenging to locate information about individual ISU Extension publications via the library website. Quick Search will list the name of the series, but it will not list individual publications within each series. The Parks Library Reference Collection has a List of Current Series, Serial Publications (Series Publications of Agricultural Experiment Station and Cooperative Extension Service), published as of March 2004. It lists each publication from 1888-2004 (by title and publication number - and in some cases it will show an author name).

Abstract

Data secured in an investigation which has now been under way for eight years at the Iowa Agricultural Experiment station give direct support to the belief that a good paying dairy herd can be built up from a foundation of common cows thru proper methods of feeding and management and thru the use of a good purebred dairy sire. The results of this work are presented in a preliminary way in this bulletin and will be given in more complete form when the investigation has been carried further.

Investigations of this kind are fundamental to the task of increasing dairy production to meet increasing demands for dairy products because they seek to find ways of getting more milk and butterfat from the overwhelming majority of common cows. There are in the United States, according to government reports, more than 20,000,000 so-called dairy animals whose average production is not half as much as it might be if proper methods of selection, breeding, feeding and management were followed by all dairy farmers. Any information that will help to build up better and more productive dairy herds from these animals is consequently of large value.
