Fat content and fatty acids profile of colostrum and milk of primitive Konik horses ( Equus caballus gmelini Ant.) during six months of lactation.

The research article explores the effect of lactation stage, number of foals, and age of the mare on the fat content and fatty acid composition in the colostrum and milk of Konik horses. It was found that these factors had minimal effect on fat content and certain fatty acids, enabling the mare’s milk to maintain its nutritional quality.

Investigation Process

• The study was conducted on 12 lactating mares of the Konik horse breed. The samples of colostrum and milk were gathered at various stages including the initial phase of lactation, the first and second days post-foaling, and every four weeks till the sixth month of lactation. This robust sampling process facilitated a thorough analysis of the changes in fat content and fatty acid composition during different stages of lactation.
• The study variables that were accounted for include the lactation stage, the number of foalings, and the age of the mare. The aim was to assess whether these factors significantly impacted the fat content and fatty acid composition of the colostrum and milk.

Findings

• The study found significant differences in the fat content and certain fatty acids between the first colostrum and the milk of mares. However, the exact variations or which variant was higher in content wasn’t specified.
• The number of times a mare had given birth and the age of the mare did not statistically impact the fat content in the milk. These factors also had minimal effect on the fatty acid composition. Consequently, these findings imply that mares, regardless of their age or the number of times they have given birth, can produce milk with consistent nutritional quality.
• The milk of Konik mares was characterized by a significant content of 18-carbon polyene fatty acids. This type of fatty acid is known for its health benefits, including reduction of inflammation and heart disease risk.
• Moreover, the milk showed a low ratio of n-6 to n-3 fatty acids. Both of these fatty acids are essential for health, but maintaining a low ratio of n-6 to n-3 is considered beneficial for reducing the risk of chronic diseases like heart disease.
• The milk’s low values of atherogenic and thrombogenic indices also highlight its benefits for heart health. A lower atherogenic index indicates less likelihood of plaque formation in the arteries, and a lower thrombogenic index reduces the risk of blood clotting.

Implications

• The findings of this study highlight the nutritional benefits of the colostrum and milk from Konik mares, despite the stage of lactation, the mare’s age, or the number of prior foalings. This underlines the potential of Konik horse milk as a consistently nutritious food source. Future research is needed to explore potential applications in the field of nutrition and health.
