The Korean study, reported in the February Journal of Dairy Science, also dispels the popular myth that calves fed a greater amount of milk experience more diarrhea. In the study, calves fed whole milk at the rate of 20 percent of bodyweight “safely consumed greater amounts of milk without any noticeable increase in diarrhea,” say the researchers. In fact, during the third and fourth week of age, the occurrence of diarrhea was lower in calves fed in a step-down fashion versus calves fed at the traditional rate of 10 percent of bodyweight. The researchers point out that diarrhea is usually related to sanitary, management and housing conditions rather than the amount of milk intake.
