“…Our results also coincide those of Jeong et al. (2018) reporting that dairy cows divided into low, moderate and high groups on the basis of blood Ca have higher glucose levels in higher Ca group. Similarly, blood metabolite concentrations during the post‐partum period, as characterized by Ca concentrations after calving, are inconsistent among studies.…”

“…Furthermore, progesterone increased with increasing blood Ca (Caixeta et al., 2017), which is associated with greater total cholesterol, glucose, albumin and earlier resumption of cyclicity in dairy cows (Jeong et al. (2018)).…”

“…According to several studies, subclinical hypocalcaemia is linked to an increased risk of reproductive disorders in high milk‐producing cows (Chapinal et al., 2012; Martinez et al., 2012; Obucinski et al., 2019b; Rodríguez et al., 2017). According to Jeong et al., (2018), higher blood Ca content (9.7 mg/dl) is connected to higher concentration of serum energy metabolites and earlier return of oestrous cyclicity in dairy cows. Similarly, lower blood Ca is associated with a negative effect on ovarian function and the condition was worse in chronic hypocalcaemic cows (Caixeta et al, et al 2017).…”

The aim of the research was to assess whether there was a link between serum calcium (Ca) after calving and serum progesterone, milk somatic cells count and Ca, and other blood metabolites in Achai and crossbred cows. Based on blood calcium level shortly after calving, thirty cows from both breeds were divided into a moderate group (≤10.0 mg/dl of Ca) and a high group (>10.0 mg/dl of Ca), with samples collected at 0, 7, 14, 21, 28 and 35 days post-partum, respectively. On day 35 of the post-partum, crossbred and Achai cows with high blood Ca recorded significantly (p < .01) higher serum progesterone, glucose, triglyceride and milk Ca compared with moderate blood Ca group; however, serum cholesterol was significantly (p < .01) higher in both breeds under high blood Ca. Incidence of subclinical mastitis was significantly (p < .01) higher in crossbred and Achai cows under high blood Ca. The results showed that blood progesterone (OR=2.095), glucose (OR=1.024), triglyceride (OR=4.571), cholesterol (OR=1.111) and milk Ca (OR=1.141) resulted in a greater concentration in crossbred compared to Achai cows. A significant (p < .01) correlation was found between blood Ca and other blood metabolites (progesterone, glucose, triglyceride and cholesterol) in both breeds. In conclusion, greater serum Ca concentration after calving is associated with greater serum progesterone, glucose, triglyceride and milk Ca in crossbred cows; however, the incidence of subclinical mastitis increased.

“…This study included 1,238 cows from 125 herds and reported a 40% decrease in the odds of pregnancy to first service for cows with (Gild et al, 2015;Gobikrushanth et al, 2020;Menta et al, 2021). Other authors have shown detrimental effects of postpartum blood Ca concentration below various thresholds on estrus cyclicity (Ribeiro et al, 2013;Rodríguez et al, 2017;Jeong et al, 2018) and number of services per pregnancy (Ribeiro et al, 2013;Braga Paiano et al, 2019). Although it is unclear how blood Ca postpartum interferes with reproductive performance, it is noteworthy to remark that Ca is an intracellular signal that leads to oocytes maturation (Homa et al, 1993).…”

Consequences of postpartum low blood calcium (Ca) concentration are still under study and literature describing this condition in Jersey cows is scarce. A prospective cohort study was conducted to evaluate the association of low serum Ca concentration shortly after calving with milk and energy-corrected milk yields, somatic cell count linear score, and pregnancy to first service and within 150 d in milk in multiparous Jersey cows from 2 commercial herds. Blood samples for serum Ca determination were collected on average at 3 h 10 min postpartum from 352 multiparous Jersey cows. Productive data up to the 10th monthly test were obtained from the Dairy Herd Improvement Association and reproductive data were obtained from herd records. Multiple linear, log-binomial, and Cox's proportional hazards regressions were used to evaluate the association of low serum Ca concentration with productive and reproductive outcomes. Serum Ca concentration ≤2.18 mmol/L was associated with 1.43 and 1.85 kg/d more milk and energy-corrected milk. However, lower serum Ca concentrations were associated with a 0.28-unithigher somatic cell count linear score per monthly test (Ca ≤2.00 mmol/L), and decreased pregnancy risk at first service (risk ratio = 0.64; Ca ≤1.94 mmol/L) and hazard of pregnancy within 150 d in milk (hazard ratio = 0.40; Ca ≤1.90 mmol/L). The present study is based on a convenience sample of multiparous Jersey cows from 2 commercial herds; further research including more herds and additional blood Ca determinations is needed to describe postpartum blood Ca dynamics and its association with productive and reproductive outcomes for the Jersey breed.

“…However, they found that hypocalcemia had no effect on first postpartum service; this could be attributed to the husbandry practices [135]. Contrary to this, higher postpartum serum calcium concentrations are associated with higher serum total cholesterol, albumin, and glucose concentrations, a lower rate of placental retention, and clinical endometritis [140]. Abnormality in calcium homeostasis is also determined as a contributing factor towards arrested follicular development and acyclic ovaries [141].…”

Major Nutritional Metabolic Alterations Influencing the Reproductive System of Postpartum Dairy Cows

Early successful conception of postpartum dairy cows is crucial in determining the optimum reproductive efficiency and profitability in modern dairy farming. Due to the inherent high production potential of modern dairy cows, the extra stress burden of peri-parturient events, and associated endocrine and metabolic changes causes negative energy balance (NEBAL) in postpartum cows. The occurrence of NEBAL is associated with excessive fat mobilization in the form of non-esterified fatty acids (NEFAs). The phenomenon of NEFA mobilization furthers with occurrence of ketosis and fatty liver in postpartum dairy cows. High NEFAs and ketones are negatively associated with health and reproductive processes. An additional burden of hypocalcemia, ruminal acidosis, and high protein metabolism in postpartum cows presents further consequences for health and reproductive performance of postpartum dairy cows. This review intends to comprehend these major nutritional metabolic alterations, their mechanisms of influence on the reproduction process, and relevant mitigation strategies.
