“…Likewise, lipids are prone to oxidation, and malondialdehyde (MDA) is generated as a consequence of lipid peroxidation, and as such is assayed as a biomarker of OS. Several methodologies are available for the quantification of MDA, but among them, the thiobarbituric acid reactive substances (TBARS) (Janero, ) are the most commonly encountered in the veterinary literature (Bernabucci et al., , ; Gabai et al., ; Wullepit et al., , ; Tanaka et al., ). This spectrophotometry method is based on the capacity of MDA to react with thiobarbituric acid to produce a red pigment.…”

SummaryDairy cows are especially vulnerable to health disorders during the transition period, when they shift from late pregnancy to the onset of lactation. Diseases at this stage affect not only the animals' well-being, but also cause a major economic impact in dairy farms, because apart from treatment costs, affected cows will not reach their peak milk-producing capacity. The overproduction of reactive oxygen species (ROS) leads to oxidative stress, which has been identified as an underlying factor of dysfunctional inflammatory responses. Supplementation with vitamins and trace elements attempts to minimize the harmful consequences of excessive ROS production, thereby trying to improve animals' health status and to reduce disease incidence. However, results regarding the effects of supplementing antioxidants on dairy cows' health and performance have been inconsistent, because in most cases, the antioxidant potential of the animals was not assessed beforehand and the nutritional strategy planned accordingly. Therefore, reviewing the physiological and harmful effects of ROS production, along with the different options available for assessing the redox balance in dairy cattle and some of the key findings of different supplementation trials, could bring one step forward the on-farm application of determinations of oxidative status for establishing nutritional strategies early enough in the dry period that could improve transition cow health.

“…Other pathologies such as mastitis (8), puerperal metritis (16) and dystocia (9) have been associated with the alteration of the reproductive performance of cattle (1). The most possible explanation of this phenomenon has been associated with elevated levels of cytokines, acute-phase proteins and cortisol, which have a negative effect on the timely release of LH and progesterone (31) altering the follicular microenvironment.…”

“…One of the main problems for farms is the delay in the resumption of postpartum ovarian activity. To obtain the ideal interval between calving (IBC) of twelve months, animals must conceive within 85 days after partum, which requires the normalization of their cyclicity (1). This is a critical event for achieving efficient reproductive performance and minimizing economic losses represented in the increase in the number of open days and services per conception.…”

“…Uno de los principales problemas en los hatos es el retraso en el reinicio de la actividad ovárica después del parto. Para obtener el intervalo entre partos (IEP) ideal de doce meses, los animales deben concebir dentro de los 85 días posteriores al parto, lo cual requiere que hayan normalizado su ciclicidad (1). Esto constituye un evento crítico para lograr un desempeño reproductivo eficiente y minimizar las pérdidas económicas representadas en el incremento en el número de días abiertos y servicios por concepción.…”

Objective. To evaluate the factors associated with postpartum ovarian resumption and follicular dynamics in Holstein cows under high altitude conditions (2,600 masl). Materials and methods. Forty-five Holstein cows were studied between 14 days before and 120 days after calving. Uterine involution, follicular dynamics, serum progesterone and peripartum pathologies were evaluated; additionally, body condition (BC), calving type, milk yield, were also evaluated. According to hormonal and reproductive findings, cows were classified into two groups: early ovarian resumption (EOR) or delayed ovarian resumption (DOR). Results. The occurrence of the first follicular for EOR animals (n=31) was produced on average 9.58±3.45 days postpartum and was similar to the DOR group (n=10) [10.8±4.83 days; p>0.05)]. The first postpartum ovulation occurred at 21.55±5.90 days (EOR) and was significantly delayed (48.7±27.85 days) for DOR animals (p<0.05). Thirty-six point five percent of the cows (n=f) had normal estrus cycles (18 to 24 days), while 63.5% (n=26) showed dysciclia. The factors associated with ovarian resumption and cyclicity were the loss of BC [OR=3.3, CI 95% (1.2-13.3) (p<0.05)] and lameness [OR= 9.0, CI 95% (1.2-13.3) (p<0.05)]. Conclusions. Although the emergence of postpartum follicular waves was observed early, under the experimental conditions of this study there are factors that may affect the first ovulation favoring the occurrence of anovulatory conditions. The determinant factors were low body condition and lameness.Key words: Anovulation, ovarian follicle, postpartum (Source: DeCS). RESUMENObjetivo. Evaluar los factores asociados con la reactivación ovárica y la dinámica folicular postparto en vacas de la raza Holstein bajo condiciones de altura (2600 msnm). Materiales y métodos. Cuarenta y cinco vacas Holstein fueron estudiadas entre 14 días preparto y 120 días posteriores al mismo. Fueron evaluadas la involución uterina, dinámica folicular, progesterona sérica y presentación de patologías en el periparto; adicionalmente la condición corporal (CC), tipo de parto y producción de leche. De acuerdo con los hallazgos reproductivos y hormonales, las vacas se agruparon en dos grupos: reactivación ovárica temprana (ROT) o retardada (ROR). Resultados. La emergencia de la primera onda folicular para animales ROT (n=31), ocurrió en promedio 9.58±3.45 días postparto y fue . Conclusiones. Aunque la emergencia de ondas foliculares postparto se presentó de manera rápida, bajo las condiciones experimentales del presente estudio, existen factores que afectan la primera ovulación favoreciendo la presentación de condiciones anovulatorias. La presentación de cojeras, y la pérdida de CC postparto fueron factores determinantes.Palabras clave: Anovulación, folículo ovárico, postparto (Fuente: DeCS).

“…Marine algae as a dietary source of pure DHA has only rarely been reported (Hostens et al 2011;Wullepit et al 2012). More recently Sinedino et al (2017) have shown that algae increased resumption of oestrous cyclicity (77.6 vs 65.9%) and pregnancy at first artificial insemination (AI) (47.6 vs 32.8%) in primiparous cows.…”

Vlcek M., Andrlikova M., Barbato O., Bina V., Boland M.P., Dolezel R., Lopatarova M., Cech S. (2017): Supplementation of dairy cows with docosahexaenoic acid did not affect ovarian activity. Czech J. Anim. Sci., 62, 457-465.The effect of docosahexaenoic acid (DHA) on ovarian activity of dairy cows was determined. Experimental cows (n = 25) were fed a total mixed ration supplemented daily with 100 g/cow of an algae product All-G-Rich (Alltech, Ireland) containing 10% DHA divided into 2 doses for 52 days. Determination of DHA from milk samples taken from all cows was performed before the All-G-Rich supplementation (on Day 0, D0), and on D21 and D42 of algae supplementation. Cows were synchronized to be in oestrus on D21 and D42 of the experimental period. Monitoring of ovarian activity was performed by transrectal ultrasonography. Examinations were performed at 2-3-day intervals from D0 until D52 of the experimental period. Plasma concentrations of progesterone, oestradiol, insulin, NEFA, and cholesterol were determined. Control cows (n = 25) were examined in the same way as the experimental cows. Milk DHA concentrations on D21 and D42 were significantly higher in treated cows (D21 1.38 vs 0.28, P < 0.0001; D42 1.34 vs 0.20, P < 0.0001). There were neither important effects of DHA on ovarian structures, nor on evaluated variables in plasma. Cows in the experimental group tended to have larger corpora lutea and higher cholesterol concentrations, but differences were not significant.
