Abstract: Foram utilizados 72 ciclos estrais de 37 éguas mestiças, com idade variando de quatro a 20 anos, distribuídas ao acaso em dois grupos experimentais (G I e G II) para estudar o efeito do local de deposição do sêmen no sistema genital sobre a fertilidade. As inseminações no ápice do corno uterino (G II) foram realizadas por via intravaginal profunda, utilizando-se a pipeta de inseminação IVI pippette (75cm), contendo 1/5 (3mL) da dose inseminante utilizada para o corpo do útero (15mL-G I). As éguas foram rufiada… Show more

“…Aurich et al (2011) reported significant changes in the ERR in successive collection procedures, but there was no increase or reduction in ERR as the number of embryo collections increased. In a study similar to ours, Xavier et al (2009) compared 72 cycles of crossbred mares and found conception rates of 42.9 % and 45.9 % (P > 0.05) for CAI and DAI, respectively, using doses of 100 ×10 6 and 20 ×10 6 PMS, respectively, lower rates than in our study. It is possible that the higher temperatures in the southeast region of Brazil may have exerted some influence on the ERR because the temperatures under which our study was conducted were cooler.…”

“…Technical advances in equine semen processing and in AI techniques have generated technologies capable to reduce the volume and the quantity of PMS used in the inseminating dose, by changing the semen deposition site in the uterus (Sieme et al 2004, Xavier et al 2009. In this case, the AI catheter is passed through the cervical canal but then transrectally guided to the apex of the ipsilateral to uterine horn ipsilateral to the ovary with the preovulatory follicle (POF), allowing reduction of the insemination dose (Samper 2001, Sieme et al 2004, Katila 2005, Lyle and Ferrer 2005, McCue 2012.…”

“…The ejaculate was filtered in a nylon filter to separate the gel fraction and then analysed for motility and vigour by optical microscope. The sperm concentration was counted in a Neubauer chamber and the semen was diluted in the proportion of one part of semen to one part of skimmed milk diluent, centrifuged at 2200 rpm (600 × g) for 10 min and resuspended with BotuSemen ® at a total dose of 250 million sperm cells (2 mL) with progressive motility (Xavier et al 2009). It was deposited in the uterine horn ipsilateral to the preovulatory follicle by flexible pipette for deep intrauterine AI because of the low dose of semen (Minitube ® , Minitube do Brasil, Porto Alegre, Rio Grande do Sul, Brazil).…”
