“…In addition, warfarin exposure resulted in decreased bone density in lambs and rats ( Simon et al, 2002 ; Chen et al, 2021 ). Notably, warfarin and DHA-Na have similar structures and mechanism of causing bleeding; therefore, DHA-Na may interfere with bone health ( Pastoureau et al, 1993 , Zhou et al, 2023 ). As such, we believe that in broiler chickens, excessive DHA-Na use in feed has detrimental effects on bone health, potentially increasing leg disease prevalence and exacerbating relevant animal welfare and economic concerns.…”
