Summary
Zinc deficiency in guinea pigs significantly reduced serum zinc, protein, and alkaline phosphatase levels. Supplementation partially restored these biochemical markers, highlighting zinc's crucial role in animal health.
Area of Science:
- Biochemistry
- Animal Nutrition
- Physiology
Background:
- Zinc is an essential trace element vital for numerous biological functions.
- Experimental models are crucial for understanding the effects of nutrient deficiencies.
- Zinc deficiency can profoundly impact metabolic processes and organ function.
Purpose of the Study:
- To investigate the biochemical effects of experimentally induced zinc deficiency in guinea pigs.
- To evaluate the recovery response of zinc-deficient animals following zinc supplementation.
Main Methods:
- Guinea pigs were fed a diet low in zinc (1.25 mg Zn/kg) for 60 days.
- Serum and tissue samples were analyzed for zinc, protein, and alkaline phosphatase activity.
- Serum protein electrophoresis was performed to assess changes in albumin and globulin fractions.
Main Results:
- Zinc deficiency led to significant reductions in serum zinc, protein, and alkaline phosphatase activity.
- Electrophoresis revealed decreased albumin and gamma-globulin, with increased beta-globulin.
- Kidney and testis tissues showed reduced zinc and protein content and alkaline phosphatase activity.
- Zinc supplementation partially improved the observed biochemical abnormalities.
Conclusions:
- Experimental zinc deficiency significantly alters serum protein profiles and biochemical markers in guinea pigs.
- The kidney and testis are target organs affected by zinc deficiency.
- Zinc supplementation can partially reverse the detrimental effects of zinc deficiency, underscoring the importance of adequate zinc intake.
