“…This increase, detected in the final third of gestation, may be a result of hormonal variations (Milinković-Tur et al, 2005), such as glucocorticoids, which promote mobilization of extrahepatic proteins and transport of amino acids to hepatocytes. The amino acids mobilized in the liver cells are used in most part in glucose synthesis, which is the main source of energy for the embryo (Satué and Montesinos, 2013). These authors found similar results for the amount of protein in Spanish mares evaluated in the final third of pregnancy.…”

“…Mean values were higher in the transition group; however, only T-15 differed from MG, similar to Mariella et al (2014) results. This increase coincides with an increase in protein synthesis (Satué and Montesinos, 2013) in the liver (Milinković-Tur et al, 2005). Fibrinogen is a pro-coagulant acute phase protein that may increase in response to an inflammatory stimulus (Mariella et al, 2014) and, during pregnancy, its concentration remains high in comparison to the non-gestational period (Hill and Pickinpaugh, 2008).…”

The present study aimed to evaluate the effects of the transition period on hematological and biochemical constituents in Mangalarga Marchador mares. Forty-eight mares were used to form a maintenance group (MG) and transition group (TG), formed by pregnant mares and, after delivery, infants. Blood samples were collected at the following times: T-60 (60 d pre-delivery), T-30 (30 d pre-delivery), T-15 (15 d predelivery), T0 (first 6h post-delivery), T15 (15 d post-delivery), T30 (30 d post-delivery), and T60 (60 d post-delivery). The TG had lower values (P< 0.05) of red blood cells, hematocrit and hemoglobin at T0, T15, T30 and T60 times than MG. The mean corpuscular volume was lower in MG (P< 0.05) than in TG (T0, T15, T30 and T60) and mean corpuscular hemoglobin concentration was higher (P< 0.05) in MG than in TG (T15, T30 and T60). On the other hand, the diameter distribution of red blood cells presented a lower value (P< 0.05) in MG than in TG (T15 and T30). Mares in transition period presented regenerative anemia. The results demonstrate physiological metabolic variations of different intensities during pregnancy, delivery and early lactation. RESUMOO presente estudo teve como objetivo avaliar os efeitos do período de transição em constituintes hematológicos e bioquímicos em éguas Mangalarga Marchador. Foram utilizadas 48 éguas para formar um grupo de manutenção (GM) e um grupo de transição (GT), composto por éguas gestantes e, após o parto, lactentes. Amostras de sangue foram coletadas nos seguintes tempos: . Éguas em período de transição apresentam anemia regenerativa. Os resultados demonstram variações metabólicas de diferentes intensidades durante a gestação, o parto e o início de lactação.

“…A hypomagnesemic tetany responsive to Mg ++ and Ca ++ administration has been re-ported in lactating mares as well (Lewis, 1995). A few researchers have dealt with adjustments occurring in a mare's physiology during the peripartum period, focusing on clotting (Bazzano et al, 2014a) and haematological (Bazzano et al, 2014b(Bazzano et al, , 2015 and biochemical profiles (Harvey et al, 2005;Aoki and Ishii, 2012;Satué and Montesinos, 2013;Bazzano et al, 2014c;Mariella et al, 2014). It has been shown that a series of hormonal and metabolic changes occur to modulate the maternal supply of energy and nutrients to the foeto-placental unit (Larsson et al, 2008).…”

“…It has been shown that a series of hormonal and metabolic changes occur to modulate the maternal supply of energy and nutrients to the foeto-placental unit (Larsson et al, 2008). As gestation progresses, the direction and magnitude of these changes in maternal organism mainly depends on the increase in foetal metabolic requirements (Satué and Montesinos, 2013). Changes in a mare's metabolism continue during the postpartum period, when a certain amount of minerals is lost through milk production (Filipović et al, 2010): equine milk contains considerable concentrations of macrominerals that vary significantly during lactation (Salimei and Fantuz, 2012).…”

The peripartum period influenced the serum macromineral profile in mares

Abstract. Changes in metabolic requirements during pregnancy may produce nutritional imbalances predisposing mares to pathological conditions. Therefore, we aimed to examine changes in serum macrominerals during the peripartum period in mares. Fifteen pregnant mares (Group A) were monitored starting at the 263rd day of pregnancy until the 21st day after foaling. Seven non-pregnant and non-lactating mares were used as a control group (Group B). Group A was subjected to blood sampling within 24 ± 12 h after parturition (P) and then 7, 14 and 21 days after foaling (+1, +2, +3 weeks, respectively). Group B was subjected to regular sampling throughout the study to ensure that seasonal changes had no significant effect on studied parameters. Serum samples were analysed for serum electrolytes including sodium (Na + ), potassium (K + ), calcium (Ca ++ ), phosphorus (P + ), chloride (Cl − ) and magnesium (Mg ++ ). Two-way repeated measures of analysis of variance (ANOVA) was applied to evaluate significant effects of peripartum on electrolyte concentrations. Group A showed a decrease in Cl − concentrations (P = 0.011) after foaling and lower P + concentrations (P = 0.015) compared to Group B throughout the study. The linear regression model showed an increase in Na + concentrations (P = 0.002) and a gradual decrease in serum Ca ++ (P = 0.001) during pregnancy. Because the most significant changes in serum electrolytes occurred within 2 weeks before and 2 weeks after foaling, monitoring serum electrolyte concentrations would indicate whether the mare needs further mineral supplementation at this stage. The significant changes in a mare's macromineral profile that we observed over the peripartum provide enhanced knowledge about mineral interrelations and their modifications during specific physiological conditions such as late pregnancy and early postpartum.

“…Alguns trabalhos reavaliaram parâmetros bioquímicos e hematológicos na gestação em éguas, resultando em desenvolvimento de intervalos de referência para essa condição fisiológica particular SATUÉ;MONTESINOS, 2013;MARIELLA et al, 2014), entre eles, alguns avaliaram glicose basal no último mês préparto (AOKI; ISHII, 2012) ou durante toda a gestação . No entanto, nenhum trabalho até o momento avaliou a tolerância à glicose, a resposta insulinêmica, assim como a insulina basal ao longo da gestação, não havendo portanto valores de referência para que se possa diagnosticar uma égua gestante como resistente à insulina e/ou portadora de Diabetes Mellitus Gestacional (DMG), como ocorre em humanos.…”
