Figure 5. Crude protein (CP) and total digestible nutrients (TDN) values by date and forage type. Bars followed by different letters, within sampling date, are statistically different. Red horizontal lines indicate % CP and TDN requirements in the diet of a dry cow (solid line; CP = 8%, TDN = 54%) and lactating cow (dashed line; CP = 11%, TDN = 60%).
