It is important in proper bunk management to move them up at a steady rate, rather than increasing intake too fast, throwing the cattle off feed and starting the cycle over again. As was mentioned earlier, many dairymen/feeders will use a self-feeder so the cattle have access to feed at all times.
The caloric needs of a recently calved cow (fresh cow) are so significant that most dairy cows do not initially eat enough to make up for the calories they are burning. This mismatch of burning more calories than the cow is taking in is a negative energy balance. In other words, the cow is using more energy than she can acquire through her diet.
Dairy cattle are those breeds that produce larger volumes of milk for a longer period of time than other cows. In the united states today, there are 6 main breeds of dairy cattle the most common dairy breeds are holstein, jersey, brown swiss, guernsey, ayrshire, and milking shorthorn.
The grading-up system, in the ayrshire cattle breed, whereby the descendants of non-pedigree cows enter the registered (herd book) population, is studied principally from three aspects: (1) its numerical importance in the population; (2) the breeding structure of herds practising grading-up, and (3) the possible genetic effect of grading-up on milk and fat yield.
Grading-up involving several improving breeds is the quickest and most efficient method of radically improving unproductive livestock and transforming breeds (for example, changing coarse-wooled breeds of sheep into fine-wooled and semifine-wooled breeds).

Diets for lactating cows 15 to 30 days in milk should provide an average of about 500 iu/day, and diets for dry cows 265 days of gestation should provide approximately 1000 iu/day. Cows during the last 14 days of gestation and the first two to four weeks of lactation may benefit from consuming 2000 to 4000 iu of vitamin e/day.
In the dairy industry, milk cows are bred back as soon as possible to keep the milk supply up and keep the cows freshly in milk, but in a smaller homestead setting, where maybe production isn’t the main goal, there doesn’t always have to be a rush to breed a milk cow back as soon as possible.

There are two different scales of scoring that one can use for judging condition in cattle: 1 to 9, which is the american scoring system (or some refer this as the beef cattle scoring system); or; 1 to 5, which is the scottish (or canadian) scoring system, or, for some, the dairy cattle scoring system.

They are prey animals so they have a fight or flight response in situations they feel afraid or threatened. An understanding of cattle behavior will improve efficiency and speed of moving animals. Injuries caused by cattle to dairy workers are common in dairy operations.
Plant breeding efforts use scientific methodology and technology to develop improved varieties.

Cattle under 30 months of age have a very thin covering of fat which is largely restricted to the back, loin, and upper ribs. Cattle qualifying for the minimum of this grade vary relatively little in their degree of fatness. Therefore, the range in cutability among cattle that qualify for this grade is somewhat less than in the higher grades.
Grading up by continuous use of purebred sires of the same breed in a grade herd improves the overall genetics and produces qualities desired from the bull. A good example would be breeding a pure bred black angus bull to grade brahman cows to eventually obtain “brangus” cattle (5/8 angus and 3/8 brahman).
Most dairy cows reach a point in their life when they transition from being a milk producer to being a beef producer. The contribution of beef from culled dairy cows and dairy steers is very important to the beef industry.
