Selenium and Vitamin E Concentrations in a Healthy Donkey Population in Central Italy.

This research study examined the deficiency levels of Selenium and Vitamin E in domestic donkeys in Central Italy. It found that donkeys may require less Selenium than horses, and that Vitamin E levels in donkeys can be low, which may lead to health issues.

Objectives and Methods of the Study

• The study aimed to determine the concentrations of Selenium and Vitamin E, two vital elements that protect against oxidative stress, in the plasma of healthy donkeys. This species-specific data was previously lacking in literature, despite the fact these nutrients are critical for general health and productivity of working animals like donkeys.
• The research divided a sample of donkeys into five groups by age, sex, and productive status – foals, yearlings and weanlings, non-pregnant non-lactating females, pregnant non-lactating females, and adult males.
• Plasma samples were taken from each donkey to test for Selenium and Vitamin E concentration, leading to group-specific data.

Results of the Study

• The study noted significant differences in Selenium concentration between the youngest group (group A) and the adult male group (group E). These results suggest that the requirements for Selenium may be lower in donkeys than in horses. The discovered range for Selenium in donkeys (0.02-0.14 µg/mL) was indeed lower than the standard recommendation for horses.
• Vitamin E levels were also studied. The study found that levels of Vitamin E in foals were lower than levels observed in adults. The documented range was between 3.29-12.99 µmol/L.

Impact of the Study

• The study provides valuable insights into the specific Selenium and Vitamin E requirements for domestic donkeys. This is crucial for formulating balanced diets for these animals, potentially preventing deficiencies and improving overall health and well-being.
• The findings would be especially useful in regions where donkeys are prime working and production animals, like Central Italy.
• The differences from horses in terms of Selenium needs denote that a species-specific approach is necessary while considering the dietary needs and health care of different equids.
