Abstract

The late pregnancy (3rd trimester) and the postpartum period (PPP) (calving date or day zero to day 45) are very critical periods for the fertility and production in dairy cows. This study was designed to investigate blood glucose, total protein (TP), calcium (Ca), phosphorus (P), magnesium (Mg), iron (Fe), and triiodothyronine (T3) during late pregnancy and the PPP. Twenty-seven apparently healthy multiparous crossbred dairy cows (Friesian × Kenana) were included in this study. The cows were randomly allocated into three groups: group A (n = 10), cows with late pregnancy, group B (n = 7), cows in the PPP, and group C (n = 10), nonpregnant cows as control. One-way ANOVA was used to analyze the data. The results of this study showed that blood glucose was higher in late pregnancy and the PPP than in nonpregnant cows. The TP was significantly lower in late pregnant cows than during the PPP and in nonpregnant cows. Ca, P, and Mg were not significantly different between periods. Serum Fe and T3 were significantly lower during the PPP than that in late pregnant and nonpregnant cows. The results can provide indications of the nutritional status of dairy cows and a diagnostic tool to avoid the metabolic disorders that may occur during late pregnancy and the PPP.

Highlights

Academic Editor: Bockline Omedo Bebe e late pregnancy (3rd trimester) and the postpartum period (PPP) are very critical periods for the fertility and production in dairy cows. is study was designed to investigate blood glucose, total protein (TP), calcium (Ca), phosphorus (P), magnesium (Mg), iron (Fe), and triiodothyronine (T3) during late pregnancy and the PPP
Blood glucose levels were within normal range (40–60) [24], and that concentration of plasma glucose was higher during late pregnancy (67.89 ± 6.52) and in the PPP (65.88 ± 5.94) than in nonpregnant cows (57.40 ± 7.90)
In the PPP, the level of serum TP was elevated compared to late pregnancy (Table 2). is is consistent with a previous study reported that serum TP levels were significantly affected from the physiological period and increased during lactation when compared to late gestation in dairy cows [27]. is change in protein concentration occurs because the cow in the gestation period experiences great metabolic stress [28]

Introduction

Academic Editor: Bockline Omedo Bebe e late pregnancy (3rd trimester) and the postpartum period (PPP) (calving date or day zero to day 45) are very critical periods for the fertility and production in dairy cows. is study was designed to investigate blood glucose, total protein (TP), calcium (Ca), phosphorus (P), magnesium (Mg), iron (Fe), and triiodothyronine (T3) during late pregnancy and the PPP. E results can provide indications of the nutritional status of dairy cows and a diagnostic tool to avoid the metabolic disorders that may occur during late pregnancy and the PPP. Many protein-related parameters are highly affected around parturition and may significantly impose to further reproductive performance [9] Animals require minerals such as calcium (Ca), magnesium (Mg), and phosphorus (P) during late pregnancy and the postpartum period for growth, reproduction, and lactation, which often affect specific requirements and serve as catalytic components of enzymes or regulate several mechanism involved in pregnancy and lactation [10, 11]. Is study aimed to assess seven blood biochemical parameters (glucose, TP, Ca, P, Mg, Fe, and T3) during the late pregnancy and PPP because these periods are very important for the fertility and production in dairy cattle. T3 and T4 were lower in animals with inactive ovaries, and low levels of thyroid hormones may delay postpartum (PP) reproductive functions [20]. is study aimed to assess seven blood biochemical parameters (glucose, TP, Ca, P, Mg, Fe, and T3) during the late pregnancy and PPP because these periods are very important for the fertility and production in dairy cattle. e results can be an indicator for the cow health and a diagnostic tool to avoid the metabolic disorders that occur during the late pregnancy and PPP
