Tuesday I went to visit the dairy barn. I arrived between morning and noon milkings. Like many modern dairies, U of S dairy milks 3 times per day, yielding 10-15% more milk and decreasing the risk of mastitis. Lots of the research they do with the dairy herd is about milk volume and nutritional content related to cow feed. How does glycerol, canola supplement, or massive quantities effect milk?
The dairy barn was commissioned in 1972, and if all goes well they will be in a new building this time next year. The building is a bit outdated, a lot has been learned about animal behaviour, chute and parlour design, and animal handling safety over the last 40 years.
