Metabolizable Energy (ME) Requirement For Suckling Goats

Use this Energy Requirement Calculator to calculate the daily energy requirements for suckling goats. Enter the data into the table and then click the Calculate Energy Requirements button. The results will be displayed in the table at the bottom of the page.


We will use a 15-pound female or wether goat (6.8 kg) gaining 100 g/day.

1. Choose gender of kid female or wether
intact male
2. Enter body weight (kg)
3. Enter Average Daily Gain (g/day)

They will be automatically entered into the table to the left.


Our example would require a total of 3.23 MJ of ME (1.89 MJ for maintenance and 1.34 MJ for gain).

Metabolizable Energy (ME) Requirement for Maintenance:
Metabolizable Energy (ME) Requirement for Gain:
Total Metabolizable Energy (ME) Requirement:

The total ME requirement can then be divided by the concentration of ME in milk or milk replacer to estimate that quantity of milk required. 3.23 MJ divided by 3.079 MJ/kg of 4% fat-corrected milk indicates need to feed or consume 1.05 kg of milk. Likewise, intake and ME concentration in supplemental dry feeds would need to be considered.

Amount (kg) of 4% fat-corrected milk needed per day:
