Early calf slaughter: impact of industry-led policy interventions on trends in Ireland, 2024.
Article in Frontiers in veterinary science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The dairy industry produces a surplus of male calves with low monetary value and slaughtering them at a young age has been used as a means of disposal, raising ethical concerns. In 2024, changes to the dairy industry quality assurance standards were introduced to prevent this practice in Ireland. The objectives of the present study were to explore trends in calf slaughter, measure the effects of the intervention, and to identify any unintended consequences of the industry-led policy. The data on 16,598 <56-day-old calves slaughtered from a total of 1,937,533 born, January to May 2024, were obtained from national databases. We fitted negative binomial regression models to the count of slaughtered calves per birth herd to assess associated contributory factors. The study revealed that there has been a drop in early calf slaughter from an average of 1.09% of calves in 2018-2022 to 0.86% in 2024. There were 1,241 birth herds of slaughtered calves but only 247 herds presented calves for slaughter. Furthermore, 1,019 of the birth herds moved calves to a presenting herd before slaughter. The birth herds were mostly members of the dairy industry quality assurance scheme (97%). The presenting herds had lower membership (83%) and tended to send larger number of calves. One single presenting herd accounted for 20% of the total slaughtered calves. These results show that the intervention had a sizable effect in its first year and highlights the potential for industry-driven policy changes to influence the choices farmers make, and the need for continual monitoring.
