  1. Thanks to Charlie Krauss for his comments. My wise dairy-farmer neighbor says this: “Always have dry available for cows when they are grazing.” I’ve noticed that my cows may graze on gorgeous grass/clover pasture and then see or hear me in the barn; they return and fill up on hay which I fork out for them. Also, this reference–http://www.fao.org/docrep/006/AD236E/ad236e16.htm –suggests that dandelions may help provide Mg and Ca for cows. We watch our cows enter a new paddock and invariably–after checking out the borders–go first for dandelions.

  2. A hundred years ago, dairy farmers around here followed a practice that protected them from grass tetany and made their lives easier.

    Just as soon as there was green grass, they would let the cows out to graze after the morning milking. They gathered them for the evening milking. At night, they fed dry fodder in a dry-lot so they wouldn’t have to gather them for the morning milking.

    Lush grass during the day and dry fodder at night made a better balance.

    A lot of cattle illness boils down to eating too much of something good – too much clover, too much grain, too much milk, etc.
