Male and female calves were randomly assigned at 4\u2009months of age to one of two groups: a non\u2010relocation group, in which the dam was moved to a separate pen while the calf remained in its original pen; and a relocation group, in which the calf was moved while the dam remained in place. Calves were observed for step counts per 24\u2009h and vocalizing counts per 12\u2009h and per hour, and for time spent feeding, lying, and ruminating over 12\u2010h periods around weaning. Blood samples were collected for hematological analysis and serum cortisol assay just before and after weaning. Calves in the non\u2010relocation group had significantly fewer steps and less vocalization than those in the relocation group after weaning. Postweaning lying, feeding, and ruminating times were significantly longer in the non\u2010relocation group than in the relocation group. Neutrophil\u2010to\u2010lymphocyte ratio and serum cortisol concentrations were also significantly lower in the non\u2010relocation group after weaning. These findings suggest that avoiding pen relocation of calves during weaning may alleviate behavioral disturbances and reduce stress associated with maternal separation in Japanese Black cattle.<\/jats:p>","DOI":"10.1111\/asj.70149","type":"journal-article","created":{"date-parts":[[2026,1,30]],"date-time":"2026-01-30T06:15:42Z","timestamp":1769753742000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects
