MILK the vital force

The 22nd International Dairy Congress was the first to offer to participants the opportunity to present their work in the form of a poster, the object being to include more con tributions in the programme than there was time available for oral presentations. The posters were also intended to ~lace. up to a point, the brief communications that were received for. and published at. previous international dairy congresses but which had been criticized on various grounds. The Organizing Committee's criteria for the acceptance of a poster included the following : - the subject matter should not have appeared in print prior to the Congress - the poster should contain useful and mainly new information - the poster should have an adequate technical or scientific basis Authors whose posters were accepted were invited to display ~r material at the Congress and be present to explain it to interested participants. The texts presented are also publ ished in this volume. The International Dairy Federation is interested in the views of Congress participants and of readers of ~his volume as to the relative value of posters vs brief communications. Any comments will be kept for consideration when future Internat ional Congresses are planned : they should be sent to TDF Secretariat at the address below.
