Magaplus artificial insemination system

Transcervical insemination (tc-ai) in swine is successful with the easy-use catheter magaplus. To complete the new tc-ai system we will design: 1. A specific packing system and/or an applicator for sperm doses. 2. A device to fix the catheter during the slowest inseminations.

Our starting point is a prototype catheter for easy uterine insemination in swine: MAGAPLUS. Our objective is: 1. To develop global equipment and a technique for TC-AI and to evaluate the transcervical technique through on-farm application. 2. To compare the obtained results 1) with results of field applications of similar technology on EU farms. 3. To examine the factors that contribute to the differences between the results of goals 1) and 2). To achieve this aim, the work program can be separated into the following work packages: WP1: Search and selection of the device for applying the sperm dose through the MAGAPLUS catheter into the uterine body of sows: - Devices in the field of reproductive medicine and veterinary science that could be adapted for the purposes of the project. - Prototypes "de novo" according to UNIVERSITY OF GERONA indications. In this case we will: 1. Carry out a technical and economic study of the prototypes: an ergonomic design and study of the functionality. 2. Research suitable material for manufacturing the catheter. 3. Prepare all documentation (technical specifications) for manufacturing. 4. Analyse management requirements, community laws and accreditation systems. For the design/selection of these devices we will evaluate: * Materials: biocompatibility, * Design: hydrostatic pressure in the sperm population, correct emptying, ergonomics, the possibility of multi-dosage, ease of use, etc. WP2: selection of the device to fix the catheter to the sow body or to the insemination crate during the slowest inseminations, something that will be more frequent in the youngest sows and gilts: - Devices in the field of swine artificial insemination that could be adapted for the purposes of the project. - Prototypes "de novo". In this case we will: 1. Carry out a technical and economic study of the prototypes: an ergonomic design and study of the functionality. 2. Research suitable material for manufacturing the catheter. 3. Prepare all documentation (technical specifications) for manufacturing. 4. Perform an analysis of management requirements, community laws and accreditation systems. For the design/selection of these devices we will evaluate: * Materials: resistance, flexibility, etc. * Design: ergonomics, ease of use, etc. WP3: Testing the selected devices in an experimental farm. We will try to get the catheter to go through the cervix orifice in the sows without any injury and to fix the catheter with the hands-free device. Performance of these mechanical experiments will be evaluated by: - The catheter position into the uterus. - The capacity for emptying the sperm container and filling the uterus during TC-AI procedures. - The capacity for fixing the catheter to the sow's body with the hands-free device. - The viability of the sperm population in-vitro after contact with the different materials used and after applying high pressure to the container walls. - The percentage of fertility and prolificacy. If necessary, improvements to the equipment and technique should be made to enhance the success rate. WP4. Testing the whole selected protocol in several farms with different breeds, ages and working conditions. WP5: Project management. Keywords: husbandry, swine, artificial insemination.
