Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

open access: yesAnimal Research and One Health, EarlyView.
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

Duck Orbivirus and Egg Production: A Newly Identified Duck Orbivirus Is the Etiological Agent of Egg Production Decline in Chinese Breeder Ducks

open access: yesAnimal Research and One Health, EarlyView.
Field samples from breeder duck farms with egg‐production decline were subjected to viral detection, genome sequencing, and virus isolation. Experimental infection demonstrated that duck orbivirus (DORV) causes a significant and persistent reduction in egg production in breeder ducks.

Glycoengineered Recombinant Alpha1‐Antitrypsin Results in Comparable In Vitro and In Vivo Activities to Human Plasma‐Derived Protein

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Alpha‐1‐antitrypsin (A1AT) is a multifunctional, clinically important, high‐value therapeutic glycoprotein that can be used for the treatment of many diseases, such as A1AT deficiency, diabetes, graft‐versus‐host disease, cystic fibrosis, and various viral infections. Currently, the only U.S. food and drug administration‐approved treatment for

Trade‐offs in avian parental care: a review of theory and meta‐analysis of brood size manipulations

open access: yesBiological Reviews, EarlyView.
ABSTRACT The selective forces shaping parental care have been studied for over 50 years. While theoretical and experimental work has yielded qualitative progress, the large body of empirical work testing predictions about parental investment based on life‐history trade‐offs has yet to be synthesized.
