Topic:Growth Factors

Growth factors are naturally occurring proteins or peptides that play a significant role in regulating cellular growth, proliferation, and differentiation in horses. These factors are involved in various physiological processes, including tissue repair, development, and immune function. Common growth factors studied in equine research include insulin-like growth factor (IGF), transforming growth factor-beta (TGF-β), and fibroblast growth factor (FGF). Their expression and activity can influence wound healing, musculoskeletal development, and recovery from injury. This page compiles peer-reviewed research studies and scholarly articles that examine the role, regulation, and clinical significance of growth factors in equine biology and health.

Postnatal changes in total and free thyroxine and triiodothyronine in foal serum.

Journal of reproduction and fertility. Supplement October 1, 1975 Issue 23 709-715

Irvine CH, Evans MJ.Total tyhroxine (TT4), free thyroxine (FT4), total triiodothyronine (TT3) and free triiodothyronine (FT3) concentrations in foal umbilical cord blood were respectively 14, 5 7 and 3 times the concentrations of these hormones in adult horse blood. The TT4 levels in foals declined rapidly to reach adult concentrations by Day 16 and FT4 levels declined steadily during the first 3 months of life. Foal TT3 levels rose during the first 10 hr after birth and thereafter declined, although they were still X2-5 higher than adult levels at 3 months of age. Levels of FT3 similarly increased after birth be...

Lowe JE, Baldwin BH, Foote RH, Hillman RB, Kallfelz FA.Surgical thyroidectomies (Thx) were per-formed in 6 yearling grade horse colts, (3 males, 3 females). Five control colts (3 males, 2 females) were included and comparative studies were carried out for 67 weeks. The comparative measurements included rectal temperature, heart rate, feed consumption, packed cell volume, serum cholesterol, serum calcium, serum phosphorus, serum TO height, heart girth, body weight, epiphyseal plate closure and tooth eruption times. A thyroprotein supplement was fed to the Thx males during weeks 46 to 53. The Thx animals failed to grow in height, were sensi-tive to ...

Background: Growth is a critical stage influencing the future athletic performance and economic value of Thoroughbreds. In pastoral systems, extrinsic factors may exert a particularly strong influence on development.Objectives: To analyze the influence of stud farm, birth month, and birth year on body weight of Thoroughbred foals raised in pastoral systems.Methods: A 10-year longitudinal study (2009-2018) included 2408 Thoroughbred foals (51% females, 49% males) from seven stud farms of Pampas region. Body weight was recorded from 5 to 19 months of age. The Brody model was used to estimate ind...
