“…The increase in bacteria counts was well expected after the use of sponges (AMIM, 1996; , 2006). The concomitant use of antibiotics is often suggested to reduce the undesirable effects caused by the sponges, but this practice may induce antibiotic resistance (SUÁREZ et al, 2006;MARTINS et al, 2009). As expected, lower CFU were observed in the CIDR group, with the OB group having a bacteria pattern similar to the use of CIDRs, which indicates advantages in terms of animal welfare, in addition to a reduced propensity for the use of antibiotics along with the devices, as it occurs with sponges.…”

“…As expected, lower CFU were observed in the CIDR group, with the OB group having a bacteria pattern similar to the use of CIDRs, which indicates advantages in terms of animal welfare, in addition to a reduced propensity for the use of antibiotics along with the devices, as it occurs with sponges. Most animals in the PSP group presented a local inflammatory reaction classified as (++), attributed to the features described above, with accumulation of secretion with repugnant odor, cloudy aspect and purulent characteristic, associated with blood clots, also observed by MARTINS et al (2009). The changes in the vaginal canal are attributed to the physical abrasiveness of the device per se, in addition to the retention of exsudate and other secretions of the genital tract (AL-HAMEDAWI et al, 2003).…”

“…All these bacteria were also present in our study. What is physiologically surprising, even by the use of sponges, is the fact that only two days after the device's removal, the vaginal bacterial population returns to levels similar to those observed prior to their insertion (AMIN, 1996;MARTINS et al, 2009). This reduction in the CFU/ml is due to the removal of the irritating agent, also promoted by the increase in local immune response caused by the estrogenic phase during proestrus and estrus.…”

“…In anestrous goats, a combination of progestagens, gonadotropins and prostaglandins is the most used program to induce estrus (Souza et al, 2011). However, the use of progestagens is under review in some countries, due to issues related to public health (output of chemical residues in food, which has led to them being banned in the United States and has caused the enforcement of the regulation in maximum residue limits in the European Union) and animal welfare (causes of potential problems, such as vaginitis and/or sponge retention; Martins et al, 2009). An alternative during the ovulatory season is based on the elimination of the corpora lutea to induce a follicular phase with ovulation.…”

The objective of this study was to evaluate the efficiency of two doses of PGF associated or not to hCG on the associated reproductive parameters in dairy goats. A total of 29 goats received two doses of 30μg d-cloprostenol latero-vulvar at a 10 day intervals (Day 1 and Day 10). The does were allocated according to body weight and body condition score into two treatments, to receive hCG (250IU) or saline at estrus onset. After the second dose of PGF, estrus was monitored and ultrasound exams were performed twice daily. All does were inseminated 16h after estrus onset. Blood collection was performed every day for progesterone assay. The use of hCG at estrus onset did not affect any studied parameter and therefore the data were pooled.

“…Los principales efectos secundarios fueron: enrojecimiento de la mucosa, secreción purulenta, aumento en el crecimiento de coliformes, infiltración de polimorfonucleares y, en menor grado, adherencias del dispositivo, lo que coincide con lo descrito por otros autores (Martins et al 2009;Manes et al 2010;Martins et al 2010, Gatti et al 2011Manes et al 2014). El 6,5% de las hembras tratadas presentaron adherencias, dato menor al 10% y 14% reportado por Martins et al (2010) y Espinoza et al (2003), respectivamente.…”

Medroxiprogesterona acetato para la elaboración de dispositivos intravaginales caseros usados en la sincronización del estro en ovinos de pelo: Evaluación de su eficacia, sus efectos secundarios y comparación con un dispositivo comercial en hatos de Costa Rica. Resumen El objetivo del trabajo fue determinar la eficacia farmacológica y los efectos secundarios de un dispositivo intravaginal de fabricación casera elaborado con acetato de medroxiprogestrona para la sincronización del estro en ovinos de pelo. Se incluyeron un total de 78 hembras adultas, multíparas y ciclando en un estudio de dos etapas. En la primera etapa se utilizaron 18 animales con el objetivo de analizar la eficacia y los efectos secundarios del dispositivo de elaboración casera. En la segunda etapa se utilizaron 60 hembras divididas aleatoriamente en dos grupos: (G1) dispositivo casero (n-30), (G2) dispositivo comercial (n-30). El fin de esta etapa fue comparar la tasa de sincronización de celos y la tasa de concepción por monta natural. Para la sincronización se colocó el dispositivo con 60mg de acetato de medroxiprogesterona durante 12 días, con inyección de 200 UI de eCG y 5 mg de dinoprost trometamina al retirar del dispositivo. Se evaluaron andrológicamente 13 machos, de los cuales 4 fueron descartados por ser insatisfactorios y se utilizaron 8 machos satisfactorios durante ambas fases del estudio. En ambas etapas la presentación de celo fue nula durante la presencia del dispositivo y 100% presentaron celo 48 horas después de su retiro. Los efectos adversos en la primera etapa fueron: Vaginitis leve al día 12 en todas las hembras, 3 presentaron adherencias, 2 hembras con aumento de fibrinógeno el día 12 y una disminución general de los leucocitos. En la segunda etapa no hubo diferencias en la sincronización entre los grupos, la tasa de concepción fue de 80,0% y 76,7% en G1 y G2, respectivamente. Basado en los resultados de este trabajo, el dispositivo intravaginal de fabricación casera es efectivo para la sincronización del estro en ovinos de pelo y para la obtención de altas tasas de preñez por monta natural.Palabras clave: Sincronización del estro, ovinos, medroxiprogesterona acetato.
