Interpretive Summary:

Technical Abstract: The objective of this study was to compare movement patterns of nursing vs. nonnursing mature cows and to characterize cow-calf proximity patterns in two herds of Raramuri Criollo cattle. Herds grazed rangeland pastures in southern New Mexico (4355 ha) and west-central Chihuahua, Mexico (633 ha)'' At each site, five nursing and four nonnursing adult cows weighing approximately 325 kg were fitted with Lotek 3300 LR GPS collars which recorded animal position at 10-min intervals for 25 d during March to April 2015. Nursing cows and their calves were also fitted with Sirtrack proximity loggers that recorded number and length of dam-calf contact events (
