Serum chemical values of gestating and lactating swine: reference values
American Journal of Veterinary Research
|May 1, 1984
Summary
Serum reference values in swine differ between gestation and lactation. Key constituents like calcium and glucose were lower during gestation, while creatinine and triglycerides were higher, highlighting physiological changes during reproduction.
Area of Science:
- Veterinary Medicine
- Animal Physiology
- Biochemistry
Background:
- Understanding physiological changes in swine during reproduction is crucial for animal health and productivity.
- Establishing reference ranges for serum constituents aids in diagnosing health status.
Purpose of the Study:
- To determine reference values for 18 serum constituents in gestating and lactating swine.
- To compare serum biochemical profiles between gestation and lactation phases.
Main Methods:
- Serum samples were collected from 33 gestating and 13 lactating swine.
- Concentrations of 18 key serum constituents were measured and statistically analyzed.
Main Results:
- Serum calcium, glucose, urea nitrogen, cholesterol, total protein, and globulin were significantly lower during gestation compared to lactation.
- Serum creatinine, triglycerides, and creatine phosphokinase were significantly higher during gestation than lactation.
- Creatinine levels showed a significant increase from day 14 to day 26 of lactation.
Conclusions:
- Significant differences exist in serum biochemical profiles between gestating and lactating swine.
- These findings provide essential reference values for assessing swine health during different reproductive stages.
