Safe and Stable Germline Transmission of MSTN Mutations in Cattle

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT With the global population expected to reach 10 billion by 2050, sustainable livestock production is critical. Gene editing of the myostatin (MSTN) gene represents a promising strategy to enhance muscle growth in cattle. In this study, MSTN‐mutated founder (F0) cows were used to generate F1 offspring via ovum pick‐up, in vitro fertilization ...

On the importance of including both sexes in animal studies – insights from home‐cage monitoring

Biological Reviews, Volume 101, Issue 5, Page 2408-2426, October 2026.
ABSTRACT A review of behavioural studies using home‐cage monitoring (HCM) systems revealed that over 61% of studies used only male subjects, with only 24% including both sexes, despite evidence of substantial behavioural differences between male and female animals. This bias could influence the outcomes of biomedical research.

Behavioral Response of Arctocephalus australis to Pedestrian Disturbance During the Breeding Season: Implications for Wildlife Tourism Management

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The South American fur seal (Arctocephalus australis) breeds in dense colonies along the Peruvian coast, mostly within protected areas managed by the Servicio Nacional de Áreas Naturales Protegidas por el Estado (SERNANP). To support responsible wildlife tourism near breeding sites, we evaluated the behavioral responses to controlled ...

MGA and PGF₂α for Estrus Synchronization

, 1987
Our goal in studying estrous cycle control is to develop a low cost system that will elicit a highly fertile, tightly synchronized estrous response in a large percentage of the treated animals. Melengestrol acetate (MGA), an inexpensive oral progestogen,

Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling

Developmental Dynamics, Volume 255, Issue 9, Page 896-914, September 2026.
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 9, Page 1390-1403, September 2026.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

Natural vs synchronized estrus: determinants of successful pregnancy in ewes using frozen-thawed Suffolk semen

Journal of Animal Reproduction and Biotechnology, 2020
The pregnancy rate in indigenous ewes inseminated with frozen-thawed Suffolk semen following natural and synchronized estrus was determined. The serum Progesterone and Estrogen concentration and vaginal electrical resistance (VER) of ewes at the time of ...

Monitoring the effects of ovariectomy on seasonal movement behavior in suburban female white‐tailed deer using internet of things‐enabled devices

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Abundant deer populations often cause conflicts in suburban communities, yet traditional population reduction methods, such as controlled hunting, can be challenging to implement. Fertility control, specifically through ovariectomy, can limit reproduction and reduce populations in certain settings, but its effect on movement behavior remains poorly ...
