'Beef-on-dairy': harnessing assisted reproductive technologies to improve performance and sustainability in seasonal-calving systems.
Review in The Journal of reproduction and development, 2026. 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
'Beef-on-dairy' describes the strategic use of beef semen on dairy females that are not required to produce replacement heifers. Adoption of beef-on-dairy systems has increased rapidly in recent years, enabled by the growth in use of sex-sorted semen to generate replacement females. This shift presents both opportunities and challenges: the rate of genetic gain can be accelerated, but the supply of high genetic merit male dairy calves will need to be generated through alternative means, and there will be an increased requirement for beef sires specifically suited for mating with dairy females. Assisted reproductive technologies, including sex-sorted semen and embryo-based approaches, offer considerable potential to enhance the genetic merit of both dairy and beef sires. When applied strategically, these technologies can accelerate genetic progress in dairy herds and improve the beef value of surplus calves born. The implementation of these technologies is challenging in seasonal-calving systems, however, and use of sex-sorted semen and embryo technologies must be carefully managed. In addition, the availability of suitable donor and recipient animals for embryo production and transfer is inherently seasonal, creating logistical constraints. Despite these challenges, more effective integration of dairy and beef breeding strategies offers substantial benefits. These include improved biological and economic efficiency of pasture-based milk and beef production, reductions in waste and animal welfare concerns, and the delivery of higher-value beef products. Ultimately, the strategic alignment of dairy and beef breeding decisions represents a key opportunity to enhance the sustainability, resilience and societal value of modern livestock production systems.
