Abstract
1. Automatic equipment for estimating mean body weight was tested on layer replacement pullets on litter and in a cage.
2. The automatic method gave as good a record as manual weighing for the purpose of controlling food intake.
3. The results suggest that care has to be taken regarding the time period over which the weighing equipment is used.
4. It is important that as many records as possible are obtained during a period of the day when body weight is not varying substantially.
