Assessing pitfalls in reproductive efficiency of dairy cattle is often confounded by milk production, animal health, energy balance, and animal management practices, among others. Methods to reduce inefficiencies are classified in the following studies as maternal endocrine management, conceptus recognition, and uterine environment. The goal was to derive some insight into the mechanisms pre and post conception that can alter rates of pregnancy establishment. The initial study ascertained the ability to reduce progesterone (P4) dominance through additional PGF2-alpha (PGF) supplementation on efficiency of timed artificial insemination (TAI) in the Ovsynch® program. The single PGF animals received the standard Ovsynch® protocol …
Effects Of Dietary Supplementation Of Conjugated Linoleic Acid In Horses, Shannon Headley
Effects Of Dietary Supplementation Of Conjugated Linoleic Acid In Horses, Shannon Headley
All Theses
Conjugated linoleic acid (CLA) reduces inflammation via the inhibition of cyclooxygenase II , thus reducing prostaglandin E2 (PGE2) production. Conjugated linoleic acid has a suggested osteoclast-suppressive role in bone remodeling and osteoarthritis, which are dependent on bone resorptive stimulator PGE2. Bone resorption marker, deoxypyridinoline (DPD), and bone formation marker, bone alkaline phosphatase (BAP), have been modulated by CLA supplementation in other species. Recent research in equine exercise physiology investigated dietary supplementation of polyunsaturated fatty acids as a possible prevention and treatment for osteoarthritis, but CLA supplementation has putative effects on skeletal function or inflammation in horses has not been reported. …
