Metabolizable Energy (ME) and Metabolizable Protein (MP) Requirements for Late Gestation or Pregnancy
(Days 91-150; 1, 2, or 3 Kids per Litter)
Use this Energy Requirement Calculator to calculate the daily energy and protein
requirements for pregnancy or gestation of goats. Enter the data into the table and
then click the Calculate Energy and Protein Requirements button. The results will be
displayed in the table at the bottom of the page.
ExampleWe will use 135 days of pregnancy with a birth weight of 3 kg and litter size of 1, 2, and 3.
