Plants vary diurnally in concentrations of nonstructural carbohydrates (TNC). Delaying forage
harvest until mid to late afternoon could result in increased TNC in forage. Ruminants can
differentiate between PM-harvested and AM-harvested grass and alfalfa hays and eat more PM-harvested
versus AM-harvested hay. In a related study, dairy cows ate about 10% more total
mixed ration containing 40% PM-harvested alfalfa hay versus the same ration containing AM-harvested
hay, produced more milk, and gained rather than lost body weight. Afternoon harvest
management could add $15/ton of alfalfa compared with morning harvesting.
