Short answer: Dairy cows are fed a balanced ration of forage (pasture, hay or silage), an energy and protein concentrate such as grain mix, minerals, and plenty of clean water. In the Farming USA 2 game, feeding is a simplified version of this, so use the game’s own in-app hints for the exact steps and use the information below for real animals.
Forage is the foundation
Cows are ruminants, and their rumen works best on fiber. Good-quality pasture, grass or legume hay, and silage should make up most of the ration. Without enough long fiber, cows can develop digestive problems and produce less milk. Our post on how much corn silage to feed a dairy cow goes deeper on one common forage.
Concentrates add energy and protein
A high-producing cow needs more energy than forage alone provides. Farms add grain mixes with corn, barley or other cereal grains, plus protein sources such as soybean meal, canola meal or distillers grains. Byproducts like beet pulp can also be useful, and you can read about their pros and cons in feeding beet pulp to dairy cows. Grain should be introduced gradually because a sudden jump can upset the rumen.
Minerals, vitamins and water
Dairy cows need calcium, phosphorus, magnesium, salt and trace minerals, plus vitamins A, D and E. These are usually supplied in a mineral mix balanced to the rest of the ration. Water matters just as much: a lactating cow drinks large amounts every day, and milk is mostly water, so fresh water should always be available.
Feeding changes with the cow’s stage
A cow in early lactation needs the richest ration. As milk production falls, the ration can become leaner. Dry cows, which are resting between lactations, need a different mix, and heifers are fed for steady growth. Farmers often work with a nutritionist who uses a ration-balancing program, since needs vary with breed, body weight, milk yield and forage quality.
Pasture-based and confinement systems
Pasture-based dairies rely on grazing for much of the ration, which can lower feed costs. Confinement systems feed a mixed ration, often called a total mixed ration (TMR), so every bite has the same balance. Both approaches work when they are well managed, and many farms combine them.
Signs the ration is off
Falling milk production, loose or very hard manure, weight loss and poor appetite can all point to a feeding or health problem. Talk to a veterinarian or livestock nutritionist rather than changing the ration repeatedly on your own. This guide is general information and does not replace herd-specific advice.
Feeding in the game versus on a farm
Farming games reduce feeding to a few taps, and the rules in a game, such as which crops cows accept, do not match real nutrition. Treat any game advice as game advice only.
Bottom Line
Feed dairy cows plenty of good forage, add concentrates and minerals matched to their milk production, and keep clean water in front of them at all times. Change feeds gradually, and call a vet or nutritionist if production or manure changes.
