Sheep - Age of ewes at last lambing

Distribution of the age at last lambing (ALL, in months) by year of slaughter and by breed type of the ewe (dairy breeds or beef breeds). The ALL is shown in the range of 10-250 months in the form of a boxplot. Individual identification and registration of small ruminants was introduced in January 2020. Analyses performed on this data may still show biases. The number of observations per year and by breed type can be found in the .csv.
