“…Gonadotropin‐releasing hormone (GnRH) analogues or LH/hCG (luteinising hormone/human chorionic gonadotropin) have been efficiently used to induce ovulation in weaned sows (Kirkwood & Kauffold, ). FTAI protocols following the use of porcine LH (pLH), in combination with equine chorionic gonadotropin (eCG) at weaning (Bennet‐Steward, Aramini, Pelland, & Friendship, ; Cassar, Kirkwood, Poljik, Bennett‐Steward, & Friendship, ) or a single pLH application at the onset of oestrus, have been proposed for weaned sows (Fontana et al., ; Ulguim et al., ; Zak et al., ). Several GnRH agonists, such as goserelin (Brüssow et al., ), licerelin (Fries et al., ), buserelin (Driancourt et al., ; Martinat‐Botté, Venturi, Guillouet, Driancourt, & Terqui, ; Möller‐Holtkamp, Stickan, Parvizi, & Elsaesse, ) and triptorelin (Knox et al., ; Taibl, Breen, Webel, & Know, ) are effective for advancing the ovulation time.…”
