A Year in the Bones: Investigating Bone Resorption Across a Reproductive Year in Wild Female Assamese Macaques

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Reproduction places considerable metabolic demands on females, particularly during pregnancy and lactation, when calcium homeostasis and bone metabolism are challenged. Urinary C‐terminal telopeptide of type I collagen (CTX‐I) offers a useful non‐invasive marker to assess bone resorption.
