Dairy & Meat Ration Optimizer

Feed is the single largest recurring cost on a dairy or beef operation, and the same ration rarely suits both a lactating cow and a finishing steer equally well. This simulation splits a herd into a dairy pen and a beef pen sharing one ration, and models each animal's daily milk yield or weight gain — and its feed-conversion ratio — as a function of the ration's crude protein and energy density. Tune the sliders to see why real farms formulate group-specific rations instead of a single one-size-fits-all mix.
