The item is a documentary film from ca. 1929 on three reels:
"Reel one: A day in the life of a Cow Testing Association Supervisor from Chilliwack. Cow testing shown in every detail and its results explained to the farmer being visited by the Supervisor. All the results are marked in a book for future reference, such as weight of milk given, butterfat content, etc. The Supervisor moves on to the next farm.
Reel two: This film is concerned with Jersey cows and shows how conformation and good looks don't necessarily make a good milker. It is impossible to tell butterfat content from looking at a cow. A little drama is staged: "Mr. Byer" and "Mr. Sellar" do a little cow trading. Sellar at first balks at the higher priced cow, not the one he fancies, but is convinced to take her, once he sees her Cow Testing Association records. Mr. G. F. Thornberry, Assistant-in-Charge of Cow Testing Association, standing talking to the two farmers.
Reel three: Cow Testing Association picnic at Coldstream Ranch near Vernon. President W.R. Powley speaks. W.F. Kennedy, MLA. for Vernon, speaks. Professor Boving of UBC speaks about Feed Evaluations. J.W. Berry, MLA, President of BC Dairyman's Association, tells jokes. Views of good sires the other important factor, besides testing, in dairy herd improvement. Shot of Dairy Commissioner Mr. H. Rome. This reel may not have been shown on occasion, the first two being the most important." (Colin Browne)
