“…The placenta's size is critical for supporting appropriate fetal growth. The weight of the placenta in the normal pregnancy group was substantially higher than that in the HDCP group, according to Esposito et al [ 31 ]. The severe group had significantly lower weeks of delivery, placental weight, and neonatal birth weight than the normal and mild groups, which was consistent with the previous study.…”

Colour Doppler ultrasound was applied for monitoring the hemodynamic parameters of fetal uterine artery (UtA), umbilical artery (UA), and middle cerebral artery (MCA) during pregnancy. In hypertension disease complicating pregnancy, these hemodynamic measures and their therapeutic applicability value were reviewed (HDCP). 120 singleton pregnant women were chosen, with 40 cases of mild preeclampsia (mild group), 40 cases of severe preeclampsia (severe group), and 40 normal control pregnant women (control group). The hemodynamic parameters of UtA, MCA, and UA were monitored in the three groups, including pulsatility index (PI), resistance index (RI), and the systolic/diastolic velocity (S/D). The parameters PI, RI, S/D, and venous catheter shunt rate (Qdv/Quv) of UtA and UA in the severe group were higher than those in the normal group and the mild group, showing the differences statistically significant ( P < 0.05 ). The PI, RI, and S/D of MCA in the severe group were lower than those in the normal group and the mild group ( P < 0.05 ). The changing trends of PI, RI, and S/D in the severe group were all first increased and then decreased in the early, middle, and later pregnancy ( P < 0.05 ). The area under the curve (AUC) was 0.98 in the receiver operating characteristic (ROC) curve created using a combination of hemodynamic measures and pregnancy outcomes, and the sensitivity and specificity for predicting bad outcomes were 94.7 percent and 96.4 percent, respectively. Colour Doppler ultrasound may accurately detect changes in the PI, RI, and S/D of UtA, MCA, and UA in pregnant women and serve as a reference for determining the intrauterine state of the fetuses and predicting bad pregnancy outcomes. In particular, the parameters in later pregnancy were higher worthy of diagnostic value for adverse pregnancy outcomes. The combination of various parameters could make an improvement of the diagnostic accuracy and provide a basis for guiding treatment as well as determining the optimal timing of delivery.

“…Monteiro et al [ 36 ] also demonstrated a high correlation between the size of the dominant follicle at TAI and both ovulation and pregnancy rate at 45 days post-AI. Furthermore, larger follicles were also associated with larger corpora lutea and augmented progesterone secretion [ 22 ], reducing the incidence of embryonic mortality [ 8 ].…”

“…On the day of AI, the animals underwent ultrasound examination (MyLab 30Gold ® ; Esaote, Genova, Italy), and the size of the preovulatory follicle was recorded. The area of the preovulatory follicle was calculated as previously described [ 22 ]:

where: FL = follicle a = major axis of the follicle b = minor axis of the follicle

The aim of this study was to evaluate the efficacy of a progesterone-based treatment on anoestrus in buffaloes. Primiparous acyclic buffaloes (n = 276), were divided into three classes according to their days in milk (DIM): from 50 to 90 (Class I; n = 86), from 91 to 150 (Class II; n = 102) and from 150 to 200 (Class III; n = 88). Animals were synchronized using P4 vaginal implants, followed by timed artificial insemination (TAI). They were then allowed to enter into a larger group of buffaloes for natural mating 15 days after AI was performed, and pregnancy status was monitored from then on at 15-day intervals. Finally, the temperature–humidity index (THI) was calculated. Statistical analysis was performed by ANOVA by means and both multiple and linear regression. The total pregnancy rate (PR) was 87.7%, with no differences among DIM classes (88.0, 92.4, and 80.0% in Classes I, II, and III, respectively). However, the PR at TAI tended to be higher (p = 0.07) in buffaloes in Class II. The follicle (FL) area in Class II buffaloes was larger (p < 0.01) than that of the other classes. No influence of the THI on the total PR was recorded. The pregnancy outcome at TAI was affected by the FL area (odds ratio = 2.237; p < 0.05) and body condition score (BCS) (odds ratio = 1.256; p < 0.05). In conclusion, treatment with vaginal P4 optimizes pregnancy rates in anoestrus buffaloes, particularly when the animals are in mid-lactation and show an optimal BCS. Furthermore, the THI does not seem to affect the efficiency of the progesterone treatment.

“…Para responder a una demanda actual creciente de leche y carne, la ganadería bovina tiene que aumentar su oferta, y por eso debe optimizar sus rendimientos al máximo (Esposito, Salzano, Russo, de Nicola, Prandi, Gasparrini, Campanile y Neglia, 2020). A la hora de intensificar la producción, uno de los objetivos es lograr un intervalo entre partos (IPP) mínimo y, un número de terneros viables comercializables máximo (Reese, Franco, Poole, Hood, Fernadez Montero, Oliveira Filho, Cooke y Pohler, 2020).…”

Presente Y Futuro Del Diagnóstico De Gestación en El Ganado Bovino

2022

Para llevar a cabo el diagnóstico de gestación en el ganado bovino, se debe utilizar un método preciso, seguro, económico y que se pueda realizar de manera temprana. Aunque varias técnicas están actualmente disponibles en el mercado, otras siguen todavía en desarrollo, siendo posibles herramientas diagnósticas a tener en cuenta en un futuro. Por ello, el presente trabajo tiene como objetivo hacer una revisión sobre las diversas técnicas de diagnóstico de gestación (DG) y su potencial uso a nivel comercial, tanto en el presente como en el futuro, de la ganadería bovina. Los métodos directos para el DG, como son la palpación directa o la ecografía del tracto reproductor vía transrectal, siguen siendo los más empleados en la actualidad durante el control gestacional en el ganado vacuno. Son técnicas diagnósticas con buenos resultados y son interesantes a nivel económico, pero son herramientas invasivas y requieren una cierta experiencia por parte del técnico que las realiza. En general, se aplican a partir de la 3ª-4ª semana posterior a la inseminación artificial. Por otro lado, los métodos indirectos de DG son menos invasivos que los directos. Mediante este tipo de diagnósticos vía indirecta se puede detectar la presencia o ausencia de un embrión, sin visualizar directamente estructuras gestacionales. Existen métodos indirectos físicos, como la vigilancia del retorno al estro, así como técnicas indirectas bioquímicas, que permiten evaluar mediante el uso de kits rápidos ciertas sustancias como la progesterona (P4) o las Glicoproteínas Asociadas a la Gestación (GPAG), producidas durante la gestación de forma temprana. Otras técnicas novedosas y prometedoras, pero que todavía se encuentran en desarrollo, son la evaluación de moléculas como el interferón tau (IFNt), los micro-ARN (miARN) y/o los Factores de Gestación Temprana (FGT).
