Fine-stemmed, mold-free hay is preferred. Fermented feeds such as haylage and corn silage can be fed to calves after weaning, provided that they are high quality. Fermented forages are only palatable as long as they are fresh. Weaned calves should be fed to grow around 1.75 pounds per day.
How much grain should our weaned calves eat?
There are guidelines on how much grain a calf should be eating in order to have a functional rumen and be weaned. The rule of thumb is that calves should be consuming about 2 pounds (about 4 cups) of starter per day for three days in a row to be weaned onto all-solid feed (Jones, and Heinrichs 2017).

- Stay in a sitting position and are able to hold their head steady.
- Co-ordinate their eyes, hands and mouth, can look at food, grab it, and put it in their mouths all by themselves.
- Swallow their food. Babies who are not ready will often push their food back out, so get more around their faces than they do in their mouths.

What should I feed calves?

What are the goals of raising calves to weaning age?
The goals of raising calves to weaning age are optimizing growth and minimizing health problems. We do this by understanding the digestive system, immune system, nutrient needs, and feed options.
What is the digestive system of a dairy calf?
The Digestive System. At birth, the dairy calf's digestive system is underdeveloped. From birth to about 2 weeks of age, the calf is a monogastric, or simple-stomached, animal. The abomasum is the only stomach compartment actively involved in digestion, and milk or milk replacer provides nutrients.
How much of a calf's stomach is omasum?
The stomach compartments grow in proportion to the calf's body size. By 12 weeks of age, the reticulum and rumen will make up more than two-thirds of the total stomach capacity. The omasum still makes up about the same proportion at 10 percent. In contrast, the abomasum comprises only 20 percent.
Why is colostrum important for newborns?
The high content of fat and vitamins A, D, and E in colostrum are especially important because the newborn calf has low reserves of these nutrients. In addition, the relatively low lactose content of true colostrum reduces the incidence of diarrhea. Table 2.

This is not the case, because calves with different body weights have different maintenance energy requirements. A constant feeding level will meet the needs of an average calf, but exceed the needs of smaller calves and fall short of the needs of larger calves, resulting in different rates of gain.

How much weight do calfs gain at 8 weeks?
Body weight at 8 weeks of age was the same for all calves and averaged 164 pounds. This meant that calves nearly doubled their birth weight by 8 weeks of age, a good parameter in any calf feeding system. Average daily gains also were similar. Height at the hips and withers was similar too, regardless of weaning age.
How long does it take for a calf to develop rumen?
The sooner starch is digested by the calf, the sooner rumen development occurs. It takes about 21 days to develop the rumen papillae from the initial time that grain is fed. This development time is from when grain is first fed, be it 2 days of age or 20 days of age.
