“…Duzinski et al (2013), informaron que la adición de 5 UI de oxitocina a las dosis seminales (3.5 x 10 9 espermatozoides en 100 ml de diluyente), mejoró en 30.5 % (94. 5 vs. 63.9 %) la tasa de parto en cerdas después de la IA durante la temporada de verano; la aplicación intramuscular de 5 UI de oxitocina no modificó este parámetro reproductivo (71.43 % vs. 69.3 %), sugiriendo que la estimulación de la contracción muscular del útero es más mayor cuando la oxitocina se adiciona al semen inmediatamente antes de la inseminación.…”

“…Estos resultados coinciden con los observados por Okazaki et al (2014) y Duzinski et al (2013), quienes comunicaron que la adición de oxitocina a las dosis de semen, fresco y congelado, no mejora el tamaño de camada al nacimiento; en tanto que Gibson et al (2004), sugirieron que la adición de oxitocina a las dosis seminales puede mejorar la fertilidad, cuando el manejo de la IA no garantiza un adecuado reservorio de células espermáticas en el oviducto; sin embargo, Peña et al (1998), al aplicar dosis seminales adicionadas con oxitocina tuvieron un incremento en el tamaño de camada (10.77 vs. 8.53). La diferencia en los resultados obtenidos por Peña et al (1998), respecto al presente estudio, pueden deberse al pobre desempeño de las hembras utilizadas en ese estudio.…”

Efecto de la adición de oxitocina al semen en la infertilidad estacional de las cerdas Effect of the supplementation of oxytocin to the semen on the seasonal infertility of the sows Romo-Valdez J romo_14@hotmail.com Romo-Rubio J* romo60@uas.edu.mx Barajas Resumen Para determinar el efecto de la adición de oxitocina al semen en el desempeño reproductivo de las cerdas servidas durante la época de verano-otoño, se utilizaron 223 cerdas multíparas híbridas, asignadas a uno de dos tratamientos en un diseño experimental completamente al azar. Los tratamientos fueron:1) Testigo (n = 111), cerdas inseminadas con dosis seminales reducidas (1.5 x 10 9 espermatozoides en 40 mL de diluyente), y 2) Grupo de prueba (n = 112), testigo más la adición de 4 UI de oxitocina antes del servicio. Las cerdas fueron inseminadas entre junio y octubre de 2012, usando la técnica de inseminación postcervical. El número de lechones nacidos totales (LNT) y nacidos vivos (LNV) fueron registrados al parto, a los que se le aplicó un ANDEVA (P < 0.05). La tasa de parto fue comparada por análisis de X 2 , utilizando tablas de contingencia 2 x 2. La adición de oxitocina al semen no modificó (P > 0.05) el tamaño de camada (11.03 vs. 10.78 LNT; 9.83 vs. 9.62 LNV). La adición de 4 UI de oxitocina al semen antes de la inseminación mejoró (P = 0.03) en 9.07 % la tasa de parto (84.68 vs. 93.75%). Se concluye que la adición de 4 UI de oxitocina a dosis seminales reducidas mejora la tasa de parto en hembras inseminadas durante la época cálida. Palabras clave: tasa de parto, tamaño de camada, oxitocina, cerda. AbstractTo determine the effect of oxytocin addition to semen on the performance of sows served, during summerautumn, 223 multi parturient hybrid sows were utilized, assigned to one of two treatments in a completely randomized design. Treatments were: 1) Control (n = 111), sows inseminated with a reduced semen dosage (1.5 x 109 viable sperms cells in 40 mL of diluent), and 2) Test group (n = 112) Control plus the addition of 4 IU oxytocin to semen before service. Sows were inseminated from June to October 2012, using the technique of post cervical artificial insemination. The total number born piglet (TBP) and total number alive born (TAB) were registered at calving, those who were compared by ANOVA (P < 0.05). The farrowing rate was compared by X2 analyses, using 2 x 2 contingency tables. The addition of oxytocin to semen doses did not change (P > 0.05) litter size (11.03 vs. 10.78 TBP; 9.83 vs. 9.62 TAB). The 4 UI oxytocin addition to semen before service improved (P = 0.03) by 9.07 % the farrowing rate (84.68 vs. 93.75%). It is concluded that the addition of 4 IU of oxytocin to the reduced seminal doses, improves farrowing rate in sows inseminated during the warm season.

This article studies the effect of a boar's birth season and breed on semen parameters and its further reproductive performance. Research material consisted of 72 boars from three breeds (24 Polish Large White PLW, 24 Polish Landrace PL, 24 Duroc × Pietrain D × P). During the whole period of the study, selected semen parameters were analysed: semen volume, spermatozoa concentration, total number of spermatozoa, total number of motile spermatozoa, number of insemination doses and also reproductive indicators: farrowing rate, total born litter size, total number of piglets born live and still, and average piglet weight. Boars born in the winter and summer months demonstrated the highest spermatozoa concentrations (383.25 and 392.37 × 10(6)/ml), total number of spermatozoa (91.75 and 93.21 × 10(9)), total number of motile spermatozoa (76.10 and 77.99 × 10(9)) and number of insemination doses (24.53 and 24.89; p ≤ 0.01). Statistically lower values for these parameters were observed for boars born in the spring and especially in autumn (p ≤ 0.01). The significant impact of birth season on farrowing rate (p ≤ 0.05) and average piglet weight (p ≤ 0.05) was confirmed for PLW boars. For the PL breed, only the total number of piglets born live was proven to be significantly affected (p ≤ 0.05). No impact of birth season was shown on semen quality or reproductive performance for D × P boars. In our study, we showed that the birth season of a boar had a more impact on the level of semen parameters, and less on the reproductive performance indicators. The results indicated that both the quality of semen and reproductive performance varied in terms of the study factors, as well as between individual breeds of boars involved in the experiment.

“…Our results are unlike previous work on the use of oxytocin in semen extenders, which was related to the possibility of improving sperm motility rather than promoting uterine contractions (11). Moreover, the addition of oxytocin in extended semen just before artificial insemination was shown to improve fertility (16) and the farrowing rate of sows (17,18).…”

The study was performed using 16 healthy warmblood stallions, aged between 15 and 20 years, from the Karacabey Stud Farm in Bursa, Turkey. The animals were kept in box stalls bedded with straw and were fed hay, oats, and pellets Abstract: Prostaglandin F 2α (PGF 2α ) and oxytocin have been used to improve reproductive performance in many mammalian species, including humans. The aim of the present study was to determine their effects on sperm quality when extended stallion semen was enriched with PGF 2α or oxytocin. In this study, 16 healthy adult stallions, each 15-22 years old, were used. Five ejaculates from each stallion were collected with an artificial vagina during breeding season. Thereafter, gel-free semen was divided into 7 aliquots and diluted with an INRA96 semen extender. The following different treatments were evaluated: 3 with only PGF 2α (10, 20, and 40 µg/mL) and 3 with only oxytocin (2, 3, and 4 IU/mL). Sperm quality was evaluated before and after applying the different treatments. In vitro addition of oxytocin to semen did not show improvement in any of the sperm quality parameters measured. However, sperm supplementation with 40 µg of PGF 2α caused a significant increase (P < 0.05) in diluted semen motility. We concluded that the addition of PGF 2α to elder stallions' semen may help maintain sperm motility. Future research might assess the effects of PGF 2α on fertility. Our results were based on in vitro evaluations, and thus further fertility trials are required.
