A balanced ration is important for a pregnant cow as it needs to be able to supply the correct nutrients to itself and its calf, making sure they are both healthy and growing correctly. This ration is suitable for such cow as the nutrients provided are all greater than the total required for the 550kg pregnant cow, which whilst in calf is better to be over than under these requirements. However, the provided nutrients in this ration if any higher may result in nutrient deficiencies to the cow or the calf.
