- Includes calf to 150 kg.
- A dairy/cow-calf farm usually has milking cows, dry cows,
heifers and calves. Multiply the number of milking/nursing
cows by 1.5 to account for the followers when they are
kept on the same farm.
- Includes offspring until weaned.
- Includes offspring to market size.
- Multiply number of sows by 2.4 to determine number of weaners.
Note. For all other animals/poultry use 1 livestock
unit per 450 kg housed at one time.
