Description
Jakub Kulus and colleagues detail in 2026 a gentler laparoscopic method for collecting eggs from very young Holstein calves, paired with hormone stimulation. Collecting eggs at two to four months could speed cattle breeding when combined with genetic selection.
Six calves received hormone injections and progesterone inserts for three days before the procedure. Surgeons punctured 127 follicles and recovered 80 egg complexes, with about two thirds graded top quality. Procedures lasted roughly one hour each. Design tweaks aimed at clearer ovary views and easier access are described step by step, so other breeding centres can judge safety and repeatability.
