Difficulty with catheter introduction, the occurrence of bleeding or semen backflow during insemination, and volume and sperm cell backflow up to 60\u00a0min after insemination were also evaluated. Sows were homogenously distributed, according to body weight loss in lactation, lactation length, weaned piglets, weaning\u2010to\u2010oestrus interval and total born in previous farrowing, in two treatments: <jats:styled-content style=\"fixed-case\">PCAI<\/jats:styled-content> (n\u00a0=\u00a0165) with 1.5\u00a0\u00d7\u00a010<jats:sup>9<\/jats:sup> sperm cells in 45\u00a0ml (2.4\u00a0\u00b1\u00a00.04 doses per sow) and <jats:styled-content style=\"fixed-case\">CAI<\/jats:styled-content> (n\u00a0=\u00a0165) with 3\u00a0\u00d7\u00a010<jats:sup>9<\/jats:sup> sperm cells in 90\u00a0ml (2.5\u00a0\u00b1\u00a00.04 doses per sow). During <jats:styled-content style=\"fixed-case\">PCAI<\/jats:styled-content>, sows were inseminated in the absence of boars. Transabdominal real\u2010time ultrasonography was performed at oestrus onset, immediately before the first insemination and at 24\u00a0h after last insemination. There was no difference (P\u00a0&gt;\u00a00.05) between treatments in farrowing rate (91.5%\u00a0\u00d7\u00a089.1%) and litter size (12.5\u00a0\u00d7\u00a011.9 piglets born, respectively for <jats:styled-content style=\"fixed-case\">PCAI<\/jats:styled-content> and <jats:styled-content style=\"fixed-case\">CAI<\/jats:styled-content> sows). Successful passage of the intrauterine catheter in all the inseminations was possible in 86.8% (165\/190) of sows initially allocated to <jats:styled-content style=\"fixed-case\">PCAI<\/jats:styled-content> treatment. Difficulty of introducing the catheter in at least one insemination did not affect the reproductive performance of <jats:styled-content style=\"fixed-case\">PCAI<\/jats:styled-content> sows (P\u00a0&gt;\u00a00.05). Bleeding during insemination did not affect (P\u00a0&gt;\u00a00.05) the farrowing rate in both treatments, but litter size was reduced in <jats:styled-content style=\"fixed-case\">CAI<\/jats:styled-content> and <jats:styled-content style=\"fixed-case\">PCAI<\/jats:styled-content> sows (P\u00a0\u2264\u00a00.06).
