and conducting the Conference . An ad hoc member who represents the company hosting the pre-conference and an OSU conference assistant also meet with the Planning Committee . Faculty members from the three universities provide continuous service on the Committee , but the other eight members serve 3-year staggered terms . The Committee meets twice each year ; once in September to plan the next Conference and it meets during the Conference .
Another milestone for the Conference occurred in 2015 when it was removed for accounting purposes from The Ohio State University to a non-profit organization 501 ( c ) ( 3 ) status . The purpose of this was to sustain the future of the Conference through changing staff at universities and policy changes at universities . A constitution and bylaws were developed and an outside firm is providing the accounting services . The Conference now operates with a Board of Directors , with a somewhat similar structure to the Planning Committee .
Multi-state programs similar to the Tri-State Dairy Nutrition Conference can serve a vital role in bringing research and Extension faculty from different universities and allied-industry professionals together to meet the educational needs of a rapidly changing dairy industry . The Conference has resulted in major impacts to the feed industry and dairy producers , and influenced students seeking careers in animal nutrition and the direction of
some research programs . Your continued support of this Conference is much appreciated .

Note : Most of the units of measure in this publication are expressed in U . S . equivalents ; however , in some cases , metric units are used . Use the following to make conversions : 1.0 lb = 0.454 kg = 454 g 1.0 ft = 0.3 m = 30 cm ° F = (° C x 1.8 ) + 32 1 U . S . ton = 2000 lb = 909 kg 1 metric ton = 1000 kg = 1.1 U . S . ton ( 2200 lb ) 1 acre = 0.4 hectare r = correlation coefficient R 2 = coefficient of determination RDP = rumen degradable protein RFV = relative feed value RMSE = root mean square error RUP = rumen undegradable protein SCC = somatic cell count SD = standard deviation SE = standard error SEM = standard error of the mean TDN = total digestible nutrients TMR = total mixed ration VFA = volatile fatty acids
Abbreviations for metric units are : ppm = parts per million mg = milligrams g = grams kg = kilograms cm = centimeters mm = millimeters m = meters
