Due to the numerous advantages that postcervical insemination offers, which we talked about in our previous post, this technique is starting to develop progressively among gilts in recent years.
Advantages compared to traditional artificial insemination in gilts:
- All the advantages of postcervical insemination mentioned in the previous post: faster, more effective and safer.
- When filling farms, the time spent for insemination drastically decreases.
- Farms where the postcervical insemination is used in multiparous allow to unify the insemination methodology.
- Farms where the traditional insemination is used in multiparous allows the total change of the technique which facilitates the work of the operator.
- Unification of the type of dose produced in insemination centres producing only doses of postcervical insemination.
Tips for performing artificial postcervical insemination in gilts:
- Size and age (135-150 kg and 7.5-8 months) at the time of being inseminated, having passed at least two heats.
- Allow at least 40 minutes between suspicion and insemination.
- When inserting the post-cervical probe:
- Have more patience, giving time for the gilt to relax the cervix
- Even if the probe is adapted to the genital tract of the gilt in some cases it may present a greater resistance.
- Lower dose pressure: smaller diameter and length of the probe and smaller volume in the uterus.
- Take advantage of this time time to continue putting catheters in other animals.
- Begin insemination with gilts and then continue with the multiparous ones.
As tools when checking that the technique is being performed correctly, we can take into account two indicators that will ensure the success of the technique.
- A success rate in the correct introduction of the probe, on more than 80% of the occasions.
- Reproductive parameters of fertility and prolificacy should be the same or better than those obtained with traditional insemination
For the introduction of this technique, specific insemination probes had to be designed to be adapted to the reproductive system of these gilts both in length and in diameter, in addition using materials sufficiently rigid to allow them to penetrate the cervix but also have the flexibility not to harm the animal in case the probe cannot progress.
Magapor offers among its products MAGAPLUSN, a postcervical probe with a specific width and diameter for gilts.
This probe is developed by our R&D&I department together with the University of Zaragoza, designed to benefit from the use of postcervical insemination in gilts.
In the study, gilts breeders reproductive genitalia were collected from 6 different genetic lines. After measuring their reproductive systems and based on the evaluation of the morphometric results of this study, the final product was designed.
This probe has distinguishing characteristics that facilitate its use in farm:
- Specific width, length and diameter for gilts, allowing a perfect adaptation during insemination.
- Optimal flexibility: gentle sliding of the probe through the cervix, sufficiently rigid to allow insemination and flexible to avoid mucosal lesions.
- Integrated dose deposition hole into the probe itself, ensuring that it is not harmful and improving the outflow.
- Frontal dose deposition probe in the uterine cavity.
- Tip integrated into the probe to avoid any risk of injury inside.
- Used with the Magapor Foam catheter for gilts, when Magaplus N exceeds the foam limit, the operator feels a slight resistance that helps him to know that he is crossing the area of the cervix.
- It incorporates a rear adapter compatible with most of the containers on the market.
- Tested under sperm toxicity controls, specific quality control for the product.
PRODUCT FUNCTIONALITY TEST: FIELD STUDY
In order to check the functionality of the probe, a field test is carried out on three farms.
During three months and in alternate weeks, 12 batches of gilts breeders were inseminated, with 6 test groups inseminated with Magaplus N and 6 control groups inseminated with traditional foam catheter for gilts.
In this test the technicians checked the handling of the probe thanks to its specific design, being inseminated gilts with great ease with Magaplus N.
The success of the product for the insemination technique is reflected in the result of 92.8% in the efficiency rate at the introduction of the probe.
Average fertility and prolificacy results during the test demonstrated the good performance of the product.
In this way, Magapor innovates in the postcervical insemination technique, making it effective, fast and common also in gilts.
