The daily mortality rate means the number of chickens that have died in a house on the same day including those that have been culled either because of disease or because of other reasons.
The number is calculated by totalling the deaths, divided by the number of chickens present in the house on that day, multiplied by 100.
You can use this spreadsheet to calculate cumulative daily mortality rates.
There is a requirement under Welfare of Farmed Animals (Scotland) Regulations 2010 for all keepers of meat chickens to keep records of cumulative daily mortality rates and to be able to provide this on demand to any licensed authority, for example, the APHA, Food Standards Scotland, local authority inspectors, etc.
