By: Samitris Lyons

  • Newborn Cow

The newborn cow is weight about 90 to 100 lbs. The baby calf is fed off of milk for three days then are fed calf starter for seven to ten days. After four to eight weeks the calf are weaned from milk.

  • Six Months Old Heifer 

The six months old heifer are fed with silage, hay, and grain. The heifers also might start to graze (eat grass) in a pasture. At  this point Holstein heifers weight about 400 lbs. The rate of growth per year for farmers are 1.6 to 1.8 lbs.

  • Yearling

This what the heifer is called after they are a year old. The heifer would weight about 700 lbs by now. Which the heifer would still need to do some more growing before entering the milk herding.

  • 2 Year Old

Farmers would refer their animals as "first-calf heifer". The heifer is now producing milk and will  also keep growing for the next few years. Then she would be fully mature and weighs about 1,200 lbs.

  • Mature Cow

The cow would be adult now and weigh over 1,5000 lbs. The heifer would be five years old and had her fourth calf. The heifer would be able to eat 100 lbs of feed a day and can produce about 12 gallon of milk a day.
