[The effect of the essential fatty acids in mare’s milk on the function of the immune system and of nonspecific resistance in rats].

The research evaluates how essential fatty acids in mare’s milk can impact the immune system and general resistance of male rats. After a 6 week diet, the rats showed increased immunity and nonspecific resistance, possibly due to the omega-6/omega-3 fatty acid ratio in mare’s milk.

Design and Methodology

• The study investigated the effect of essential fatty acids of mare’s milk fat on the immune system and nonspecific resistance in male rats, specifically focusing on the omega-6/omega-3 fatty acid ratio.
• The subject group consisted of male rats, each weighing between 135-145g.
• The rats were put on an isocaloric purified diet containing 15% of the test fat (a mix of lard and sunflower oil) for 6 weeks. The diet was designed to provide an omega-6/omega-3 fatty acid ratio of 0.76, similar to that found in mare’s milk fat.
• The progression and effect of the diet on the subject group were observed over the stipulated period.

Findings

• The research observed that the group of rats fed with the diet mimicking the fat content of mare’s milk exhibited an increase in their immune responsiveness and nonspecific resistance. These changes were noted on the 6th day after the rats were immunized with a 5% sheep erythrocyte suspension.
• These findings suggest that the essential fatty acids in mare’s milk could potentially play a crucial role in boosting the immune system and general resistance in mammals, at least in the context of the studied rats.

Implications and Further Research

• The results of this study provide promising insights into how certain dietary elements, in this case, the fatty acids from mare’s milk, can affect the immune system of mammals.
• This research invites further investigation to explore the impact of mare’s milk on the human immune system or on other animals with different diets and living conditions. It would be valuable to determine whether similar impacts on nonspecific resistance and immune function are observed.
