Description of Figure 2: A line and bar chart showing the trend in animals slaughtered in Wales since 2008. The light blue bars indicate the monthly number of animals slaughtered while the dark line indicates the 12-month rolling average of animals slaughtered. There were 9,529 animals slaughtered in the 12 months to June 2023, a decrease of 1.8% compared with the previous 12 months when there were 9,700 animals slaughtered.
The overall trend for animals slaughtered due to bovine TB control is variable. Much of the rise since 2014 is attributable to increased use of high-sensitivity testing. For example, gamma-testing, removal of Inconclusive Reactors (IRs) and severe interpretation of the skin test have all been used with the intention of clearing up infection and reducing the risk of the disease spreading and breakdowns recurring.
The monthly series is variable, and peaks can be expected from time to time. There had been an increase in the trend since the peak in October 2018 was reached, this has since fallen. Further analysis of this trend up to June 2019 has been published in the statistical article: Analysis on the number of animals slaughtered due to bovine TB controls, October 2018 to June 2019.
