Ayrshire calf Valiantlee, Grass Root Dairies

In order for a cow to produce milk, she must give birth to a calf. At around 15 months of age, she will be impregnated and, after nine months, will give birth to her first calf. After birth, the calf is fed her colostrum and then usually separated a few hours after birth. The cow becomes part of the milking herd and will continue to produce milk for about 10 months. On average, Canadian dairy cows will give birth to two to four calves. Most female calves are added to the dairy herd. A few of the male calves are kept as bulls.
