The major drawback is more disease and digestive upset risks. Usually the volume must be reduced 15% (calves may not consume one gallon in one feeding) making the milk replacer richer (15 versus 12 percent solids). This may work in warm conditions and housing (we would be nervous about using once a-day feeding in outside housing in cold winter climates). Research indicated under good management that it can work; but you must monitor calves for illness and other disorders. In some parts of the world it is very common. Try it on several bull calves to monitor success.
