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

Veterinary 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

Effect of serum anti‐Müllerian hormone levels on the superovulation response in Holstein heifers

Veterinary Medicine and Science, Volume 10, Issue 4, July 2024.
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

Effects of repeated embryo flushing without PGF2α administration on luteal function, percentage of unwanted pregnancy and subsequent fertility in mares

Equine Veterinary Journal, Volume 56, Issue 4, Page 796-805, July 2024.
Abstract Background PGF2α is commonly given at the end of embryo flushing (EF) to shorten the interval to the next oestrus and ovulation. Objectives To determine the effect of repeated EF on plasma progesterone concentration, percentage of mares with endometritis, unwanted pregnancy and subsequent fertility in mares flushed without the use of PGF2α ...
