Optimisation of Laser‐Assisted Biopsy Parameters in Bovine Embryos

ABSTRACT Although laser‐assisted biopsy has shown advantages in other species, optimised protocols for bovine embryos remain scarce. This study developed a systematically optimised laser biopsy method for bovine embryos, which demonstrated high post‐biopsy survival rates. Key parameters including laser energy, needle diameter, and operating medium were refined to establish a reliable and efficient standard protocol. This technical advance provides critical support for large‐scale embryo genomic selection in cattle, facilitating enhanced genetic breeding outcomes.
