“…Similar IAIU pipette fixing results were obtained by Dallanora et al (2004a), 97.4%; Bennemann et al (2004); 100%; Bennemann et al (2006), 98.1%, andDiehl et al (2006), 95.9%. However, none of these authors inseminated nulliparous sows and the success reported by Bennemann et al (2004) of 100% was obtained by inseminating only pluriparous sows.…”

“…Similarly, Watson & Behan (2002) did not observe any loss in the reproductive performance of the sows with the presence of blood after insemination. Conversely, Dallanora et al (2004a) reported that return to estrus rate in sows in the presence of blood was higher (12.8%) than that of the others (2.6%).…”

“…Even with the high backflow volume observed in the collections, the total backflow spermatozoids was lower in the females submitted to intrauterine insemination, compared to those inseminated by intracervical insemination. The deposition of the spermatozoids at the initial/medium third of the uterus probably facilitated their fast progression towards the spermatic reservoirs, thus allowing for higher retention of cells in the genital tract (Dallanora et al, 2004a). Another hypothesis is that the presence of the catheter in the uterine horn can induce the release of hormones that stimulate the uterine contractibility, therefore allowing for more efficient spermatic transport (Martínez et al, 2002).…”

“…Thus, under the studied conditions, any spermatic concentrations and tested volumes can substitute traditional insemination without causing damage (Table 7). Watson & Behan (2002) inseminated sows with one, two and three billion; Dallanora (2004a) and Panzardi (2006) used 1.5 billion spermatozoids per dose; and Bennemann et al (2004) used one and two billion spermatozoids per dose. They accomplished the analyses by counting the number of embryos in the uterus of the females.…”

-The objective of this study was to evaluate the reproductive performance of sows artificially inseminated by the intrauterine (IAIU) technique. The experiment was arranged in a randomized complete block design, with 300 sows being distributed in five insemination techniques: control, intra-cervical (IAIC) with 3x10 9 spermatozoa/ 100 mL; intrauterine (IAIU) with 1x10 9 spermatozoa/100 mL; intrauterine with com 1x10 9 spermatozoa/50 mL; intrauterine with 5x10 8 spermatozoa/100 mL; and intrauterine com 5x10 8 spermatozoa/50 mL. The sows submitted to intrauterine insemination presented a farrowing rate of 90.8% and return to estrus rate of 9.2%, which did not differ from the rates obtained by the intra-cervical technique (90.0% and 10.0%, respectively). Total litter size did not differ between the techniques, with the means being from 11.4 to 11.9 piglets at farrowing. Although 4.6% of the sows submitted to intrauterine artificial insemination had difficulty with pipette insertion into the cervix, 100% of them were inseminated.When evaluating semen backflow, no difference was found between the intra-cervical and intrauterine insemination techniques. However, total semen backflow was higher in sows submitted to inter-cervical insemination. No difference was found in the presence of blood between the two methods evaluated. Hence, any of the intrauterine insemination techniques can substitute inter-cervical artificial insemination without damaging the reproductive performance of the animals.Key Words: intra-cervical insemination, intrauterine insemination, semen backflow, swine Desempenho reprodutivo de matrizes suínas inseminadas pela técnica intrauterinaRESUMO -Um experimento foi realizado com o objetivo de avaliar o desempenho reprodutivo de matrizes suínas inseminadas pela técnica intrauterina (IAIU). Em um delineamento inteiramente casualizado, 300 fêmeas foram distribuídas em cinco técnicas de inseminação: controle -intracervical (IAIC) com 3x10 9 espermatozoides/100 mL; intrauterina (IAIU) com 1x10 9 espermatozoides/100 mL; intrauterina com 1x10 9 espermatozoides/50 mL; intrauterina com 5x10 8 espermatozoides/100 mL; e intrauterina com 5x10 8 espermatozoides/50 mL. As fêmeas inseminadas pela técnica intrauterina apresentaram taxa de parto de 90,8% e taxa de repetição de estro de 9,2%, que não diferiram das taxas obtidas pela técnica intracervical (90,0% e 10,0%, respectivamente). O total de leitões nascidos não diferiu entre as técnicas, com média geral de 11,4 a 11,9 leitões por parto. Apesar da dificuldade na passagem da pipeta em 4,6% das fêmeas submetidas à inseminação artificial intrauterina, 100% das fêmeas foram inseminadas. Na avaliação da ocorrência de refluxo de sêmen, não houve diferença entre as técnicas de inseminação intracervical e intrauterina. Entretanto, o total de espermatozoides refluídos foi maior nas fêmeas submetidas à inseminação intracervical. A ocorrência de sangramento não diferiu entre as técnicas estudadas. Portanto, qualquer uma das técnicas de inseminação intrauterina po...

“…A inseminação artificial cirúrgica garante a possibilidade de reduzir o número de espermatozoides com a deposição da dose inseminante próximo à junção útero-tubárica (Krueger et al, 1999;Krueger & Rath, 2000). Entretanto, como não pode ser realizada de forma rotineira nas granjas suinícolas, técnicas que viabilizam a deposição do sêmen o mais próximo possível do local da fecundação, de forma não-cirúrgica, foram desenvolvidas para possibilitar o uso de menores volumes e número de espermatozoides (Dallanora et al, 2004). Uma delas é a inseminação artificial intrauterina.…”

RESUMO -A pesquisa foi conduzida com o objetivo de avaliar diferentes tipos e volumes de diluentes por meio do desempenho reprodutivo de 72 fêmeas suínas inseminadas artificialmente. Utilizou-se o delineamento em blocos ao acaso, em esquema fatorial 3 × 2, com três diluentes e dois volumes inseminantes. O sêmen utilizado foi obtido de três machos de fertilidade comprovada. Os ejaculados foram diluídos em partes iguais com os diluentes comerciais A, B e C, constituindo doses com 1,5 bilhão de espermatozoides em volumes de 15 ou 30 mL. As variáveis analisadas foram taxa de parto, índice de retorno ao estro, número total de leitões nascidos, número de leitões nascidos vivos, mumificados e natimortos e peso da leitegada ao nascimento. Não foram observadas diferenças entre as taxas de parto e as taxas de retorno ao estro. As maiores médias de número total de nascidos, nascidos vivos e peso de leitegada foram de fêmeas inseminadas com doses contendo os diluentes B e C. Não houve diferenças entre os volumes inseminantes dentro dos diluentes B e C para nenhuma das variáveis.Para o diluente A, o volume que proporcionou maior tamanho de leitegada e número de leitões nascidos vivos foi o de 15 mL.O número de leitões natimortos e mumificados não diferiu entre os tipos e volumes de diluentes. A inseminação intrauterina de fêmeas suínas de ordem de parto 2 a 5 com doses inseminantes de 15 mL diluídas em diluentes de curta duração (diluentes B ou C) permite índices de desempenho reprodutivo satisfatórios. Palavras-chave: diluentes, porcas, reprodução, volumes inseminantes Types and volumes of diluents for intrauterine artificial insemination in swineABSTRACT -The study was conducted with the objective of evaluate different types and volumes of diluents through the reproductive performance of 72 artificially inseminated sows. A randomized complete design was used in a 3 × 2 factorial arrangement, with three diluents and two semen volumes. The semen used was obtained from three boars of known fertility.The ejaculates were diluted in equal parts, with the commercial diluents A, B and C, constituting semen doses of 1.5 billion spermatozoids in volumes of 15 or 30 mL. The analyzed variables were farrowing rate, indexes of return to estrus, total number of piglets born, number of piglets born alive, mummified and stillborn piglets, and litter weight at birth. Differences were not observed between the farrowing rates and indexes of return to estrus. The greatest means of total number of piglets born, piglets born alive and litter weight at birth were from females inseminated with semen doses containing diluents B and C. There were no differences among the inseminating volumes within the diluents B and C for any of the variables. For diluent A, the volume that provided the largest litter size and number of piglets born alive was 15 mL. The number of stillborn and mummified piglets did not differ between the treatments. The intrauterine insemination of sows from two to five parities, with inseminating doses of 15 mL diluted in short te...

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.
