How many pounds of feed does an average dairy cow eat in a day?

An average dairy cow consumes a significant amount of feed daily to support its milk production and overall health. The correct answer reflects the biological needs of a lactating cow, which typically requires around 90 pounds of feed per day, depending on factors like their size, age, and stage of lactation. This consumption is essential not only for milk production but also for maintaining the cow’s energy balance and nutritional needs.

In dairy management, understanding the feeding requirements is crucial because proper nutrition directly affects milk yield and quality. Factors like the cow's health, the type and quality of forage available, and the addition of concentrates and supplements can influence daily feed intake. Recognizing that an average dairy cow can consume nearly 90 pounds of feed is important for feeding management and herd health planning.

Other figures, like those given in the other choices, fall short of the average consumption necessary for optimal dairy performance. This knowledge is vital for anyone involved in agricultural practices, especially within dairy farming.
