The Hay Chart
The following alphabetic chart provides nutritional data for common forages. Variations occur from field to field. Remember that growing conditions, maturity, and soil nutrients affect all mineral percents.

If you have javascript enabled in your browser, you can sort columns. Forages in light green are grasses. Those in light orange are legumes. Legumes are higher in calcium and have a calcium/phosphorus ratio with more calcium than is recommended for most guinea pigs.
