Cattle are kept for two main purposes: beef production and milk production. The management of a dairy herd differs markedly from that of beef producing animals, for milk production is a daily process.

The life of a dairy cow may be divided into three periods.

The first period is the one which lasts from the birth of a dairy calf up to about the age of 6 months. The second period lasts from 6 months until the heifer calve a for the first time, usually at about 2,5 years of age. The last period is the period of the maturity of a dairy cow.

The calf being normal after birth, the cattleman should leave it with its mother. Being healthy, the calf will soon get to its feet and start nursing. The first milk, colostrum, is very important for the new-born calf. It ic secreted by the cow for 4 or 5 days after calving. The calf usually sucks its dam for about a week. Then it should be put into an individual pen and taught to drink milk from a pail. Calves should be fed whole milk at the same temperature as milk from the udder of the cow, the rate being about 1 to 1.5 gallons a day. Feeding cold milk or too much milk will cause scours. Feeding at irregular intervale may cause digestive troubles too.

Calves being 3 weeks old, other feeds containing fibre should be given. All calves at this age should have access to a small amount of good-quality hay and clean water.
Calves should be turned out to pasture in spring as early as possible. Being kept on good pasture in summer, calves do not require any other additional feed. Calves being on poor grass, large amounts of hay, roots and a small amount of concentrates are necessary in addition to pasture. In winter calves should receive legume or grass hay. The quantity of grain is different, depending on the quality of hay fed to the calves.
