Background and Aim: Hypocalcemia in goats occurs around the time of parturition and is caused by decreasing level of
calcium less than 10 mg/dL. This investigation characterized the hematological and biochemical profiles of peri-parturient
hypocalcemia in goats and study the effects of hypocalcemia on uterine involution during the postpartum period on day 0
and then weekly postpartum (day +7, +14, +21, +28, +35, till +42).
Materials and Methods: Forty-five polyparous native breed does age 3-5 years and weighing 40–60 kg were assigned
to control and hypocalcemia groups based on their health history, clinical and biochemical findings. The control group
included 10 clinically healthy pregnant does, and the hypocalcemia group included 35 late pregnant does that suffered from
anorexia, weakness, muscle tremors of the hind limbs, and an inability to stand. Clinical examination and blood sampling in
both groups were performed approximately 14 days before the expected time of kidding (day −14), at kidding day (day 0),
on day +21, and +42 postpartum. Sonographic measurements were used to monitor uterine involution on day 0 and then
weekly once the animal was postpartum (day +7, +14, +21, +28, +35, till +42) in both groups.
Results: Results of sonographic measurement revealed that the hypocalcemia group had a greater (p<0.05) size of the
uterus as assessed transrectally and retarded uterine involution when compared with the control group. Laboratory findings
revealed that does in both groups showed lower red blood cells, packed cell volume%, and hemoglobin (Hb) concentrations
on day −14 before kidding and day 0 when compared with postpartum measurements. A significant increase (p<0.05) in
total leukocyte counts, neutrophil, serum glucose, and cortisol levels with a significant decrease (p<0.05) in lymphocytes.
Significant decreases (p˂0.05) in serum calcium, phosphorous, vitamin D, and total antioxidant capacity levels with
significant (p˂0.05) increases in serum malondialdehyde were recorded on day 0 and day −14 in the hypocalcemia group
when compared with the control group.
Conclusion: This investigation provides evidence that hypocalcemia in does causes both metabolic and oxidative stress
during peri-parturient periods while also retarding uterine involution during postpartum periods.
