| 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... |
