“…There are two procedures for depositing spermatozoa into the pig uterus: surgically [37,38] or nonsurgically. An intrauterine AI with low numbers of spermatozoa is surgically accomplished by placing a small semen volume (0.5 mL) close to the uterotubal junction of each uterine horn [39].…”

“…The high number of sperm needed for a satisfactory result is partly a consequence of the anatomy of the reproductive organs of the sow, with very long uterus horns, and partly because of large losses of live sperm during storage and transport and also after insemination. Therefore, low dose insemination techniques (with a minimum of 50 million spermatozoa per dose) such as deep-uterine insemination (DUI) have been developed (Rath, 2002). Hedeboe et al (2004) have shown that sows that were inseminated with this technique showed no differences in pain reactions and scratches in the mucosa of the cervix compared to the conventional methods.…”

This paper constitutes a review on the welfare aspects of piglet castration that considers the scientific literature published after 2004. Castrating during the neonatal period (1 to 3 days of age) is clearly painful. In addition, inflammatory processes may take place at the sites of incision, thus adding further pain to the procedure. Surgical castration with general and local anaesthesia, in combination with long-term analgesia, has been shown to reduce pain but the additional handling and injection of the anaesthetic, the effectiveness and limited safety margins have to be thoroughly evaluated. Raising entire males during the whole fattening period or immunocastration of males towards the end of the fattening period are other alternatives with welfare benefits in young pigs compared to current surgical castration, but with some potential welfare drawbacks regarding handling stress and behaviour during fattening. Based on the current knowledge, it can be concluded that sperm sexing and raising entire males after genetic control of boar taint are potentially preferable alternatives to current practices, but need further research, as these methods are not yet available.

“…After IUAI, up to 30% of spermatozoa are excreted retrogradely in the pig [35] and are detected in the vaginal smears of tammars and possums [2]. Tammar spermatozoa are also broken down in the tract by phagocytosis [16].…”

Timing of artificial insemination (AI) in marsupials is critical because fertilization must occur before mucin coats the oocyte during passage through the oviduct. In this study, timing and the site of insemination were examined to develop AI in the tammar wallaby (Macropus eugenii). Birth and postpartum (p.p.) estrus was synchronized in 46 females. Epididymal spermatozoa (n=4) or semen collected by electroejaculation (n=42) were inseminated early (4-21 h p.p.) into the urogenital sinus (n=7), the anterior vaginal culs de sac (n=7), the uterus by transcervical catheter (n=5), or the uterus by injection (intrauterine artificial insemination, IUAI) (n=5). A further 16 females were inseminated late (19-48 h p.p.) by IUAI. All females were monitored for birth. A third group of six females was inseminated late (21-54 h p.p.) by IUAI and 0.4-6.6 h later, sperm had reached the oviduct in all animals. In total, an oocyte to which spermatozoa were attached was recovered and two young were born after IUAI using epididymal (n=1) or electroejaculated (n=2) spermatozoa, but no young resulted from insemination at other sites. Two females were successfully inseminated at 43 and 47 h p.p., later than most other animals, and the third was inseminated much earlier (18 h p.p.) but with highly motile spermatozoa. These young represent the first macropodids born by AI and the first marsupials conceived using epididymal spermatozoa.
