Use of industrial wireless endoscope in intrauterine artificial insemination in sheep

Abstract

The aim of this study was to evaluate the use of an industrial wireless endoscope on the pregnancy rate of Hampshire Down sheep with intrauterine insemination. The work was carried out in a farm of the community Sullkataca Baja of the municipality of Laja, department of La Paz, Bolivia. The conditioning of an endoscopy equipment (Wifi Endoscope®, Teslong) which had a portable and multifunctional Wi-Fi camera with fiber optic 8.5mm diameter, LED light and real-time video transmission at 720P. Also, 2 metal trocars (used in cattle) were adapted to facilitate the entrance of the endoscopy and the insemination pipette. The estrus synchronization was performed in 10 nulliparas and 10 multiparas by means of intravaginal sponges with 60 mg of medroxyprogesterone acetate (Progespon®, Lab. Syntex Argentina) for 14 days. A dose of 500 IU of eCG (Sergon®, Lab. Bioveta Czech Republic) is applied to the removal of the sponges. At 52.31 ± 0.31 hours post removal of the sponges, artificial insemination fixed time (FTAI) was performed with frozen semen in straws of 0.25cc with 40 million spermatozoa. During insemination, the values of 80% and 100% of uterine horn turgor were determined for the group of pluriparas and nulliparas respectively. The pregnancy diagnosis was performed at 50 days post insemination using ultrasound transrectal (EMP 820 vet plus®, Emperor China). Gestation rates were 60% for lambs and 70% for ewes (P≥0.05). In conclusion, the industrial wireless endoscope is an economical, versatile equipment and can be used efficiently to perform intrauterine IATF with frozen semen in sheep.
