Fatty acid composition of the plasma lipids of the maternal and newborn horse.

This study is exploring the composition of fatty acids in the plasma lipids of newborn and mother horses. The research suggests that the placenta, more than the fetus itself, may facilitate the creation of essential long-chain polyunsaturated fatty acids.

Research Methodology

• The study utilized samples of blood and milk collected from 3 mares and their foals, these collections were carried out daily from the first day post-partum up to the ninth day.
• In an extended study, samples were also collected from a total of 12 mares and their offspring on the 22nd, 30th and 51st days post-partum.

Key Findings

• The research noticed an increase in plasma concentrations of triacylglycerol and phospholipid during the neonatal period. This phenomenon has been documented in other species.
• Moreover, significant changes were likewise observed in the composition of foal plasma phospholipid after birth.

Implications of the Study

• The observed transformations may suggest that the placenta plays a pivotal role in the elongation and desaturation process of essential fatty acids to provide long-chain polyunsaturated fatty acids to the fetus.
• This insight adds another perspective to the understanding of fetal development, particularly the source and management of essential nutrients.

This study provides valuable insights that can guide future research in understanding the fetal development and contributions of the placenta in various species. The data can potentially be useful in animal health and nutrition – especially in breeding horses.
