Laparoscopic Embryo Transfer in Swine: An Effective Alternative to Traditional Open Surgery

Reproduction in Domestic Animals, Volume 61, Issue 5, May 2026.
ABSTRACT While embryo transfer (ET) has not yet been widely adopted in the commercial swine industry, it is an essential tool in biomedical research, including the creation of gene‐edited pigs. Traditionally, ET in pigs is performed by open surgery (laparotomy), an effective but invasive and time‐consuming method associated with risks such as infection

Assessing Long‐Term Changes in Endometrial Morphology and Functionality in Dairy Cows With Metritis

Reproduction in Domestic Animals, Volume 61, Issue 4, April 2026.
ABSTRACT This study evaluated the long‐term impact of metritis on endometrial morphology and functionality in dairy cows. Postpartum Holstein cows (n = 107) were enrolled in a cohort study at the University of Idaho Dairy Center. Metritis was diagnosed using a Metricheck device within 12 days in milk (DIM) based on the presence of fetid, watery ...

Fertility of Crossbred Dairy Cattle After Progesterone‐Supplemented Co‐Synch in Southwestern Ethiopia

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
In Ethiopia, the reproductive efficiency of dairy cattle utilizing artificial insemination (AI) is low, and implementing estrus and ovulation synchronization protocols could enhance the efficiency. Therefore, this study was designed to evaluate the effect of progesterone (P4) supplementation during Co‐Synch on estrus response (ER) and pregnancy per AI (

Antimicrobial prescribing guidelines for horses in Australia

Australian Veterinary Journal, Volume 103, Issue 12, Page 781-889, December 2025.
The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses.

Evaluation of the Accuracy and Performance of Two Commercial Pregnancy‐Associated Glycoprotein Tests for Early Pregnancy Detection in Cows

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
Early pregnancy diagnosis contributes to increasing productivity and profitability in dairy farms. The performance of AOPT and AMPT used for early pregnancy diagnosis in dairy cattle was evaluated for the first time together. AOPT and AMPT are practical methods for early pregnancy diagnosis, 28 days after insemination in dairy cows. ABSTRACT The aim of

Safety of Live Attenuated ASFV‐G‐ΔI177L/ΔLVR Vaccination in Sows With Advanced Pregnancies

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
African swine fever (ASF) causes severe disease in domestic pigs and wild boars and often results in 100% mortality. The use of attenuated strains in ASF vaccine development, based on the most recently studied ASF virus (ASFV)‐Georgia (ASFV‐G) strain, has proven effective.

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

Equine 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 ...
