Effect of birth type and sex on growth performance, wither height, humerus‐radius bone dimensions, humerus–ulna growth plate width and selected hormone profile in growing Gurcu goat kids

open access: yesVeterinary Medicine and Science, Volume 10, Issue 5, September 2024.
This study found that sex and birth type can influence growth, bone development and hormone levels in Gurcu goat kids. Males grew faster and had wider growth plates than females. Twins had higher calcitonin levels at younger ages. Growth hormone and thyroid hormones changed with age, whereas IGF‐I levels were positively correlated with growth. Abstract

This study showed that serum AMH concentrations in Holstein heifers did not change after SO treatment. Furthermore, in this study, as AMH levels in Holstein heifers were in a narrow range, a relationship between AMH and SO response could not be determined. In future studies, we believe that it would be more useful to plan more studies in Holstein donor

Using mycobacterium cell wall fraction to decrease equine chorionic gonadotropin after abortion

open access: yesEquine Veterinary Journal, Volume 56, Issue 4, Page 806-814, July 2024.
Abstract Background Equine embryonic loss following the development of endometrial cups delays return to cyclicity due to the production of equine chorionic gonadotropin (eCG). Natural degradation of endometrial cups coincides with an influx of immune cells at 100–120 days of gestation, but therapeutic stimulation of reduced eCG production has been ...
