Metabolizable Energy (ME) Requirement For Mature Goats
(Meat, Dairy, And Indigenous; > 1.5 Years Of Age; Non-lactating And Lactating)
Use this Energy Requirement Calculator to calculate the daily energy
requirement for mature goats. Enter the data into the table below and
then click the Calculate Energy Requirement button. The results will be
displayed in the table at the bottom of the page. If the doe is in the last 2 months of gestation, click on the Gestation Energy Requirement Calculator. The ME requirement will then be added to the total requirement.
ExampleWe will use a 50-kg mature dairy doe with no change in body weight (0 g average daily gain
(ADG)) and a dietary ME concentration of 10.0 MJ//kg DM.
