“…PCAI has been widely studied in multiparous and primiparous sows [27][28][29][30][31][32][33][34][35][36]. In recent years, there have been many PCAI trials in nulliparous gilts [2,8,31,[37][38][39], with different results. Therefore, more studies and research are needed to improve the PCAI technique in gilts.…”

“…The main aim of artificial insemination (AI) is to deposit enough viable sperm in the appropriate place of the female genital tract at the optimal moment relative to ovulation. For gilts, current protocols recommend the deposit of multiple semen doses (two or three) in the cervix each 12-24 h after estrus detection (2-4 × 10 9 sperm at 60-100 mL per dose, stored at 17 • C for a maximum period of 3-7 days, depending on the extender) [1,2]. Reasons for repeated AI lie in the brief viability of both oocytes and spermatozoa in the gilt reproductive tract and the difficultly of exactly predicting ovulation during estrus [3].…”

“…The post-cervical artificial insemination (PCAI) procedure was proposed as a new technique for depositing semen in the uterine body, as an alternative to cervical AI (CAI). PCAI and CAI differ not only in the semen deposition site but also in the sperm concentration and dose volume used for AI [2,4,5]. PCAI promotes efficient genetic progress, minimizes semen backflow during the insemination process, and decreases the time to conduct the AI procedure, without reduction in litter size and farrowing rate [2,4,6,7].…”

Current protocols for gilts recommend the deposit of multiple semen doses in the cervix each 12–24 h after estrus detection. Our objectives were: (1) to determine the effect of buserelin and a single fixed-time artificial insemination using the new post-cervical artificial insemination technique (FTAI-PCAI) on reproductive and productive performance in gilts, and (2) to compare this protocol with conventional estrus detection and double PCAI without hormonal induction. In the control group (C; n = 240), gilts were inseminated twice (8 and 12 h from estrus onset). Gilts in the treatment group (T; n = 226) received buserelin (10 μg, intramuscular) 120 h after altrenogest treatment (18 d) and one single PCAI 30–33 h after buserelin administration. The groups did not differ in reproductive and production performance (p > 0.05). The T group showed greater piglet birth weight and shorter estrus duration (p < 0.001). Delivery batch length differed significantly depending on the season (p < 0.05); the shortest length corresponded to autumn. Both groups only differed significantly in spring (p = 0.018), with a shorter length in the T group. This new FTAI-PCAI protocol with buserelin is recommended in gilts, helping with optimization of genetic diffusion, boars, and semen doses.

“…Regarding the use of a specific device designed for gilts (16-mm-diameter catheter and 2.5-mm-diameter intrauterine cannula), the success rate was higher (60% versus 37%) compared to the use of the same catheter (16 mm) with a larger-diameter cannula (3.5 mm) (HERNÁNDEZ-CARAVACA et al, 2017). Similarly, SUÁREZ-USBECK et al (2019) observed that the insertion of the cannula was possible in 77.5% of gilts when a catheter and a cannula specifically designed for gilts were used. Recent results using a cannula specific for gilts (3.0-mm diameter) also indicated percentages close to 60% of gilts in which cannula insertion was possible in all inseminations performed during estrus (WILL et al, 2021).…”

Perspectives of intrauterine artificial insemination applicability in gilts

The application of the intrauterine artificial insemination (IUAI) technique allows optimization of a swine production system due to the reductions in volume and number of sperm cells in the insemination dose, and by reducing the time taken to perform the insemination. However, IUAI is not recommended for gilts due to the difficulty of intrauterine cannula passage through the cervix. This difficulty is associated mainly with the fact that the reproductive tract is smaller in gilts than in pluriparous females. However, few studies have evaluated the application of IUAI in gilts. In these studies, there are variations in approach concerning the definition of the success rate for cannula passage through the cervix, the type of cannula and the body characteristics of the gilts used, making it difficult to extrapolate the recommendation for the use of IUAI in gilts. Considering the evidence that such characteristics influence or even determine the success of the application of IUAI, there is a necessity for an understanding of the influence of these factors in the improvement and later application of the technique. Gilts represent about 15-20% of the breeding group, and the use of IUAI could optimize the processes of insemination on farms. The approach used in this review highlights the aspects that could aid in structuring further studies for improving IUAI in gilts, allowing its use on commercial farms.

Over the years, reproductive efficiency in the swine industry has focused on reducing the sperm cell number required per sow. Recent advances have included the identification of subfertile boars, new studies in extended semen quality control, new catheters and cannulas for intrauterine artificial insemination (AI), and fixed‐time AI under commercial use. Therefore, it is essential to link field demands with scientific studies. In this review, we intend to discuss the current status of porcine AI, pointing out challenges and opportunities to improve reproductive efficiency.
