Resumo: This study aimed to evaluate the use of porcine luteinising hormone (pLH) given at oestrus onset in gilts to synchronise ovulation. A total of 120 gilts (40/treatment) were assigned in three treatments: control - application of placebo by intramuscular (i.m.) route at oestrus onset; pLH2.5 - application of 2.5mg of pLH by i.m. route at oestrus onset; pLH5 - application of 5mg of pLH by i.m. route at oestrus onset. On average, the interval onset of oestrus to ovulation did not differ (P>0.05) among treatments (control - 28.7±1.6h; pLH2.5 - 28.2±1.6h; pLH5 - 27.5±1.6h). The frequency distribution of gilts ovulated in different moments after oestrus detection was not affected (P>0.05) by the treatment. In conclusion, the use of 2.5mg or 5mg of pLH given at oestrus onset in gilts by i.m. route does not advance and synchronises the interval onset of oestrus to ovulation.
