He has 100 female deer age 3–15 months. The deer require 22 MJ of metabolizable energy per day during the spring months. The deer are being fed a mixture of 50% wheat and 50% silage. The wheat contains 85% dry matter (DM) and has 12.5 MJ metabolizable energy per kilogram of DM. The silage has 30% dry matter and 10.5 MJ metabolizable energy per kilogram of DM.a) How many kilograms of feed are required per day to feed the 100 deer?b) Calculate the energy (in MJ) converted to body tissue on a daily basis.
