This cannulating procedure predominantly looks at the types of food they eat and how nutrients from different food sources goes into milk production. We drink a fair bit of milk between us (about 13 million litres every day in the UK alone) and the more the cows produce, the richer Waitrose can become. So there’s a lot of dollar riding on these meandering beasts of the field. If farmers can get elbow deep in a cow’s stomach and figure out what food makes the most/best milk they can tailor the poor cow’s diet to maximum milky effect.
Paradoxically the cannulated cows are often the healthiest in the herd. Seems a bit odd? So farmers will quite often have one in their herd, even if they aren’t doing any research. Get this, this is mad – if a normal cow in the herd is unwell, they take some fluid from the cannulated cow’s hole and feed it to the sick one. So basically they feed one cows stomach juice to the other to sort out it’s jippy bowels! At least they aren’t feeding them their own brains any more I guess.

If you are eager to learn how to put one of these bad boys into your local heifer, I’ve found a video on how to do it. It’s a bit gnarly, and it’s half an hour long so I wouldn’t bother unless you really are up for popping a flange in a cow.
