Dairy
Dairy Herd Goals • Want year ‘round calving to maximize facilities. • Want one year calving interval to have the cow at peak lactation as much as possible
Imaginary Dairy Herd • 365 cows • One cow calves every day so…… – One cow ends VWP daily – One cow gets bred every day – One cow gets dried off every day
Peak lactation curve Peak Lactation Need to calve to lactate
Peak lactation - Goal 60 Day Dry Period 2 peak lactations in 2 years = most milk
Peak lactation - Bad Lost Milk No Dry Period 1 peak lactation in 2 years = less milk

Beef
Beef Cow Goals • Wean as many pounds of calves as possible each year.
Beef Cows • Limited breeding season…. • Leads to a limited calving season. • Allows weaning of all calves at ‘about the same age’. • ‘All in all out’
