We came across this article the other day and have to admit, it gave us a chuckle. Of course, we’re fans of data in all its many forms, but being based in downtown Seattle, we don’t get many chances to think about it in the context of cows – er, make that calving management. But the article provides fodder for a crunchy little morsel of usefulness. The author explains that there is an existing method for collecting data on dystocia (cows with difficult labor in delivering calves). It’s been around since 1978, and involves a five-point scale. The scale ranges from 1 – no problems in delivery, 2 – slight problem, 3 – assistance needed, 4 – considerable force required (we’re picturing an episode of James Herriot’s All Creatures Great and Small), to 5 – extreme difficulty or surgical intervention. The controversy involves a new proposed scale from 1 (no problems), 2 (one-person pull) to 3 (severe traction or surgery). On an intuitive level, this sounds nice and simple, right? Who needs those extra points on the scale anyway? Well, dairies do. Reducing the spectrum from five points down to three means that the resulting data will be less sensitive to what’s really going on. And that makes it less reliable for decision making. Moral of the story? Pay attention not only to the data being collected, but the metrics used to collect it. Simpler is not always better. […]
