A relatively common feed for lactating dairy cows, summer bulb turnips deliver top quality feed crop when the amount and/or nutritive value of summer pastures is lacking.
Continuing on with our summer turnip theme that we started back in episode 23, in part two of this two-part summer turnip series, we’ll cover off practicalities of feeding summer bulb turnips. The importance of the careful transitioning of cows from pasture-based diets to one that contains summer bulb turnips is explained. Expected performance and milk responses by cows to summer turnips are discussed as well how to avoid animal health, or milk taint issues when cows eat bulb turnips.
