Feeding cows late afternoon or evening has been shown to move more calving times to between 6:00 a.m. and 11:00 p.m. This management practice is known as the Konefal feeding system, writes Maddy Krueger. It is believed calving can be triggered by low rumen pressure. Rumen contractions increase in frequency after feeding, causing increased rumen pressure which declines by daytime, making cows more likely to calve.

INSIGHTS: For cows set to calve in March or April, there’s still time to transition to an evening feeding schedule.
