Повний текст джерелаThe study evaluated the reproductive performance of primiparous sows submitted to post cervical insemination (PCAI) compared to cervical artificial insemination (CAI). Difficulty with catheter introduction, occurrence of bleeding or semen backflow during insemination, and volume and sperm cell backflow up to 60 min after insemination were also evaluated. Sows were homogenously distributed, according to body weight loss in lactation, lactation length, weaned piglets, weaning-to-estrus interval and total born in previous farrowing, in two treatments: PCAI (n= 165) with 1.5 x 109 sperm cells in 45 ml and CAI (n= 165) with 3 x 109 sperm cells in 90 ml. Transabdominal real time ultrasonography was performed at the moment of standing heat and 24 h after last insemination. There was no difference between treatments in farrowing rate and litter size (P > 0.05). Successful passage of the intrauterine catheter in all the inseminations was possible in 86.8% (165/190) of sows initially allocated to PCAI treatment. Difficulty of introducing the catheter in at least one insemination did not affect the reproductive performance of PCAI sows (P > 0.05). Bleeding during insemination did not affect (P > 0.05) the farrowing rate in both treatments, but litter size was reduced in CAI and PCAI sows (P ≤ 0.06). Percentage of spermatozoa present in backflow was greater in CAI than PCAI treatment (P < 0.01). No difference (P > 0.05) was observed in farrowing rate and litter size according to the percentage of spermatozoa in backflow (Low: ≤ 20%; High: > 20%). It’s possible to perform the PCAI in primiparous sows with doses containing 1,5 x 109 sperm cells without detrimental on reproductive performance.

The objective of this study was to evaluate the reproductive performance of gilts subjected to post-cervical artificial insemination (PCAI) compared to traditional artificial insemination (TAI). We also evaluated the degree of difficulty in bypassing the cervix, time required to perform the insemination, presence of bleeding after insemination, semen backflow, as well as the volume and the total reflow cells 30 minutes after insemination. Gilts submitted to PCAI (n = 279) were inseminated with 45 mL doses of 1.5 x 10⁹ sperm cells and the ones submitted to TAI (n = 273) were inseminated with 80 mL doses with 2.5 x 10⁹ cells. The bypassing of the cervix was possible in 91.04% (254/279) of gilts. The difficulty bypassing the cervix in at least one of the gilt’s PCAI procedures happened with 41.58% (116/279) of the females, but it did not affect reproductive performance (P>0.05). The presence of bleeding after insemination did not affect the farrowing rate and total number of piglets born for both treatments (P>0.05). The average time needed to carry out the PCAI was 1.47 minutes and the TAI was 4.04 minutes. The percentage of sperm present in the reflux was higher in TAI than the PCAI, but no correlation was found between litter size and the percentage of sperm in reflux (P>0.05). There was no statistical difference (P>0.05) in farrowing rate (89.38% and 91.76%) and the total number of piglets born (11.63 and 11.81) between TAI and PCAI treatments, respectively. Thus, it is possible to perform the post-cervical artificial insemination in gilts without causing a reduction in reproductive performance, using doses with a concentration of 1.5 x 10⁹ sperm cells
O objetivo deste trabalho foi avaliar o desempenho reprodutivo de nulíparas submetidas à inseminação artificial pós-cervical (IAPC) comparada à inseminação artificial tradicional (IAT). Foram avaliados a ocorrência de sangramento, refluxo durante à inseminação, dificuldade no transpasse da cérvix, volume e o total de células refluídas até 30 minutos após a inseminação. As fêmeas submetidas à IAPC (n=279) foram inseminadas com doses na concentração de 1,5 x 109 diluídos em 45 mL e as fêmeas submetidas à IAT (n=273) foram inseminadas com doses na concentração de 2,5 x 109 diluídos em 80 mL. O transpasse da cérvix foi possível em 91,04% (254/279) das leitoas. A dificuldade no transpasse da cérvix, em pelo menos uma das inseminações, foi de 41,58% (116/279) e não comprometeu o desempenho reprodutivo (P>0,05). A presença de sangramento durante a inseminação não afetou a taxa de parto nem o número de leitões nascidos totais para ambos os tratamentos (P>0,05). O tempo médio necessário para a realização da IAPC foi de 1,47 minutos e a IAT foi de 4,04 minutos. O percentual de espermatozoides presentes no refluxo foi maior na IAT do que na IAPC, não sendo observada diferença no tamanho de leitegada de acordo com o percentual de espermatozoides no refluxo (P>0,05). Não houve diferença estatística (P>0,05) taxa de parto (89,38% e 91,76%) e no número de leitões nascidos totais (11,63 e 11,81) entre os tratamentos IAT e IAPC, respectivamente. Desta forma, podemos concluir que pode - se realizar a inseminação artificial pós-cervical em leitoas sem causar redução no desempenho reprodutivo, utilizando doses com concentração de 1,5 x 109 células espermáticas

Повний текст джерелаNeste trabalho, pretendeu-se expor e caracterizar as performances reprodutivas e produtivas do efectivo de porcas de uma suinicultura industrial em ciclo fechado. Realizou-se igualmente um ensaio experimental comparativo de métodos de inseminação artificial. Neste ensaio foram avaliadas as diferenças no que diz respeito aos valores de fertilidade e prolificidade das porcas, cobertas por inseminação artificial cervical, inseminação pós-cervical com cateter de esponja e a inseminação artificial pós-cervical com cateter em espiral (kubus). Para tal utilizou-se um total de 123 porcas, distribuídas por 41 grupos de 3 porcas que foram inseminadas por um dos três métodos de inseminação em estudo. Na análise zootécnica das performances produtivas e reprodutivas das porcas, verificou-se que a época do ano (Verão, Outono, Inverno e Primavera) de cobrição das porcas não afectou os parâmetros reprodutivos e produtivos das porcas. Após a 3ª parição, verificou-se uma melhoria acentuada do intervalo entre partos, no intervalo desmame cobrição fecundante e na produtividade. No triénio 2008-2010 observou-se uma redução do intervalo desmame cobrição fecundante e do intervalo entre partos e do número de leitões por ninhada mas, a produtividade das porcas aumentou em cerca de 2 leitões/porca/ano. Os resultados do ensaio experimental mostraram que as diferentes técnicas de inseminação artificial das porcas não afectaram significativamente a sua fertilidade nem o número de leitões nascidos por ninhada.
ABSTRACT - Conduct of reproduction in pigs: zootechnical analysis and comparative study of artificial insemination techniques - The productive and reproductive performances of the sows in a farrowing to finish swine unit were characterised. Moreover an experimental study to compare three different methods of artificial insemination (AI) was performed. In this trial the fertility rate and the litter size of 123 sows (41 groups of 3 sows), fertilised by cervical AI or two post-cervical AI techniques (sponge or kubus catheter) were analysed. Results show that the matting season (summer, fall, winter, spring) have no significant effect on the productive and reproductive performances of the sows. After the 3rd farrowing, there was a significant decrease in the farrowing interval and in the weaning-conception period and an improvement in the number of piglets weaned per sow per year. During the years 2008-2010, despite a decrease in the number of piglets per litter, the productivity of the sows increased by 2 piglets/sow/year as a result of a decrease in the duration of the productivity cycle of the sows. Results of the experimental trial show that the different AI techniques have no significant effect in the fertility rate and in the number of piglets born per litter.

Повний текст джерелаFixed-time artificial insemination (FTAI) associated to post cervical artificial insemination (PCAI) allows a wider use of high indexed boars and an expressive reduction on labor requirements in swine production. The aim of this study was to evaluate FTAI efficiency according to different AI protocols, using pLH – porcine luteinizing hormone - as ovulation inductor. A total of 597 weaned sows whose estrus detection was performed once daily (08:00 am) were allocated into three treatments: Control (n= 199) – the first insemination was performed at estrus onset (0 h) and repeated every 24 h thereafter, during estrus; FTAI1 (n= 199) - sows received a 5 mg (4 ml) i.m. injection of pLH at estrus onset, and were inseminated 24 h after, and FTAI2 (n= 199) - sows received 5 mg of pLH but were inseminated at estrus onset (0 h) and 24 h after. PCAI with homospermic doses (1.5 x 109 total sperm cells/50 ml) were performed in all treatments. Hormonal treatment did not affect the interval onset of estrus to ovulation (P>0.05). The number of inseminations was 2.9, 1.0 and 2.0 for Control, FTAI1 and FTAI2 respectively. Treatments did not affect farrowing rate and total born (P>0.05). Total piglets born per insemination dose was different (P<0.0001) among treatments (4.5, 12.5 and 6.2 for Control, FTAI1 and FTAI2 respectively). The use of pLH at estrus onset associated to a single fixed-time PCAI 24 h after does not compromise the reproductive performance of multiparous sows.

Our objectives were to determine: the effectiveness of upfront PGF2α injection to regress the corpus luteum; ovulation response to GnRH; and pregnancy outcomes. Dairy heifers (n = 545) from three locations (Florida, Kansas, and Mississippi) were assigned randomly to each of two treatments: 1) 25 mg of PGF2α injection and insertion of previously used autoclaved CIDR on d 7 followed by 100 µg of GnRH administered on d 5, and a 25 mg PGF2α injection at CIDR removal (7D) on d 0; 2) 100 µg of GnRH and insertion of previously used autoclaved CIDR on d 5 and 25 mg of PGF2α injection at CIDR removal (5D) on d 0. Artificial insemination (AI) occurred after detected estrus from d 0 to 3. Those heifers not detected in estrus were inseminated on d 3 and given a second 100 µg of GnRH. Blood collected on d 7 and 5 was assayed to determine concentrations of progesterone, presence of a CL (progesterone ≥1 ng/mL) on d 7, and whether luteolysis occurred in 7D heifers. Blood progesterone concentration from d 0 and 3 determined if luteolysis occurred in all heifers. Ovarian structure maps on d 5 and 0 were used to determine ovulation in response to GnRH on d 5. Pregnancy was determined on d 32 and 60 and intervening pregnancy loss was calculated. Of those heifers in the 7D treatment having progesterone ≥1 ng/mL on d 7, the proportion having progesterone <1 ng/mL 2 d later (luteolysis) was greater (P < 0.05) than that in the 5D treatment (43.0 vs. 22.9%, respectively). Total proportion of follicles that ovulated per heifer was numerically greater in the 7D treatment but only differed (P < 0.05) between locations. A treatment x location interaction was detected for pregnancy rates per AI. The Kansas location had no detectable treatment differences. In contrast, the 7D treatment produced greater (P < 0.05) pregnancy rates in the first replicate of the Florida location and at the Mississippi location. We concluded that the 5D protocol was not effective in producing acceptable luteolysis, pregnancy, and ovulation rates in comparison with the modified 7D protocol.
