Introduction
Artificial insemination (AI) is widely used in the global cattle industry to enhance genetic potential and streamline breeding. However, AI also carries the risk of introducing bacterial pathogens to herds. To mitigate this, antibiotics are added to semen extenders...

ABSTRACT
Twin births in dairy cattle is generally unfavorably associated with reproductive performance and calf survival in dairy cows. Genetic selection to reduce twinning rate in dairy cattle may be desirable, provided no undesirable correlated responses...
Nitrogen use efficiency (NUE) is a growing focus in dairy farming, as it directly impacts environmental sustainability, farm economics, and overall herd health. This study analyzed 278 Holstein-Friesian grazing dairy cows, evaluating how their NUE (nitrogen used and stored...

Abstract
Sole ulcers, a common cause of lameness is the costliest non-infectious foot lesion in dairy cows and one of the most prevalent non-infectious foot lesions in freestall housing systems. Costs associated with sole ulcers are treatment costs, plus...
Summary:
Monitoring blood metabolites is essential for assessing dairy cattle health, but traditional methods are time-consuming, costly, and stressful for cows. This study explored a more efficient approach by integrating in-line near-infrared (NIR) milk spectroscopy with on-farm data (days in...
Dairy cattle breeds have a limited genetic pool, making them vulnerable to recessive genetic disorders. Traditional methods for identifying these defects often miss conditions related to immune or metabolic issues, as they can be mistaken for environmental diseases.
This study...
The detection of highly pathogenic avian influenza (HPAI) H5N1 in U.S. dairy cattle in March 2024 prompted an urgent scientific response. Researchers at the Vaccine and Infectious Disease Organization (VIDO) launched a study to determine how the virus affects...
Supplementing dairy cows with omega-3 (n-3) fatty acids (FA) during late pregnancy and early lactation positively affects their reproductive health. A recent study examined how n-3 FA impacts ovarian follicles and the endometrium by modulating the endocannabinoid system (ECS)...
Summary
Research investigated the effects of supplemental in-stall LED lighting on dairy cattle preferences and behavior. By testing three LED light colors—white, yellow-green, and blue—the study aimed to determine whether cows exhibited a preference for specific light conditions in free-stall...
