How come I keep hearing that alfalfa is bad for male goats? The primary cause of urinary calculi is excessive PHOSPHORUS in the calcium to phosphorus ratio. The ideal calciumhosphorus ratio is 2:1 or higher. Grass hay ranges from 1:1 to 1.5:1. Alfalfa runs around 5:1. Grain runs 1:6 to 1:8, depending on the type of grain. So it would seem that some alfalfa is a good thing, and would help to balance the heavy phosphorous in grass. Grain in any significant quantity should probably be avoided, or at least carefully balanced against alfalfa. Any thoughts?
