Effect of Milk Supplementation on Bone Development in Pre-Pubertal Pigs

Creator:: Batty, Brandon S.
Abstract:: Bone is much more than a simple, static organ. While its classical functions of mineral storage, organ protection, and locomotion still hold true, further studies into the skeleton have revealed a dynamic system capable of signaling, communication, remodeling, and responding to various stimuli. Overall skeletal health is critically important to...
