Effect of different selenium supplementation levels on selenium status in camel

Area of Science:

• Animal Nutrition
• Trace Element Metabolism
• Veterinary Medicine

Background:

• Selenium is an essential trace element crucial for various physiological functions.
• Camelid nutrition research is vital for optimizing livestock health and productivity.
• Understanding selenium bioavailability and its impact on camel physiology is important.

Purpose of the Study:

• To evaluate the effects of oral sodium selenite supplementation on selenium levels in camels.
• To assess the impact of different selenium dosages on serum, urine, and fecal selenium concentrations.
• To investigate the correlation between selenium supplementation, glutathione-peroxidase activity, and vitamin E levels.

Main Methods:

• Twelve female camels were divided into three groups receiving 0, 2, or 4 mg of oral selenium daily for 3 months.
• Feed intake, body weight, serum, urine, and fecal samples were monitored throughout the study.
• Serum selenium concentration and glutathione-peroxidase (GSH-Px) activity were measured.

Main Results:

• Oral selenium supplementation significantly increased serum selenium concentrations in supplemented groups.
• Maximum serum selenium levels were observed in camels receiving 4 mg, reaching fourfold higher than baseline.
• Selenium concentrations in urine and feces also increased, with significant correlations found between serum Se, GSH-Px, and excretion levels.

Conclusions:

• Oral sodium selenite supplementation is effective in increasing selenium status in camels.
• Dosages of 2 mg and 4 mg selenium daily yielded comparable increases in GSH-Px activity.
• Further research may explore optimal selenium supplementation strategies for camel health and performance.
