Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Simulating the effect of forces pit ventilation on ammonia emission from naturally ventilated cow houses with CFD [PDF]
Atmospheric NH3, mainly originates from agricultural sources, can cause serious environmental problems related to eutrophication and soil acidification. Emissions from dairy houses are 15% of total agricultural NH3 emissions.

Cows with ketosis during the perinatal period often experience damage to the liver, a core metabolic organ, thereby exacerbating the disease's inherent vicious cycle. This study indicates that serum 3‐IAA concentrations were reduced in ketotic cows and show a significant negative correlation with hepatic TG content.
