Because their rumen isn't fully developed. Calves are born as monogastrics, with the other three chambers as only sacs of useless skin along with their abomasum or their true stomach, which resembles the stomach of all other omnivores and carnivores. The rumen doesn't start to begin to develop until a week after the calf is born; the rumen completes development by the time the calf's 3 to 4 months old. So when calves suckle the milk from their mothers, the milk is directed straight to their true stomach, which is designed to use and break down the proteins, amino acids and nutrients from the milk (containing animal proteins!) for the calf's growth and development. The rumen doesn't start developing until the calf starts to consume or "taste test" forages that its mother eats, which is by the time a calf is around a week old.
