Lipids in horses are a diverse group of organic compounds that include fats, oils, waxes, and certain vitamins. These molecules are essential components of cell membranes and serve as a major energy source for equine metabolism. In horses, lipids are involved in various physiological processes, including energy storage, insulation, and the synthesis of hormones. The study of lipids encompasses their biochemical properties, metabolic pathways, and their impact on equine health and performance. Research in this area investigates the role of dietary lipids, the effects of lipid metabolism on equine diseases, and the implications of lipid profiles in athletic horses. This page compiles peer-reviewed research studies and scholarly articles that explore the biochemical roles, metabolic regulation, and health implications of lipids in horses.
PEARSON PB, SCHMIDT H.On the basis of studies with Shetland ponies it appears that a daily intake of 38 µg of pantothenic acid per kg. of body weight is adequate to permit normal growth and health in the horse.
The amount of pantothenic acid excreted by the renal pathway is influenced by the levels ingested. On the level of 150 µg daily per kg. of body weight 41 per cent was excreted in the urine whereas when the level ingested was 38 µg per kg. of body weight only 12.7 percent was excreted by the renal pathway.
The objective of the present study was to characterize the nutritional composition, fatty acid profile, and IgG concentration of the milk produced by Chilean Corralero horse (CCH) mares from breeding farms located in southern Chile. Forty-five milk samples were collected from three of the biggest breeding farms (coded as A, B and C) specialized in breeding and selection of CCH in Chile (15 mares sampled per farm). Farms differed in days in milk (DIM). A negative association between DIM and ash, milk protein, milk solids, saturated fatty acids (SFA), and gross energy (GE) was found, whereas DIM...
Qin X, Xi L, Zhao L, Han J, Qu H, Xu Y, Weng W.Gut microbiota exerts a pivotal function in host nutrient metabolism and maturation of the mucosal immunity. Analyzing the reciprocal interaction between horses and gut microbiota constitutes a crucial aspect of scientific feeding practices. This study aims to investigate the differences in gut microbiota among Hequ horses, Mongolian horses, and Thoroughbred horses, as well as between Thoroughbred horses at two age stages. Unassigned: Paired-end sequencing with a read length of 2×250 bp targeting the V3-V4 region of the 16S rRNA gene in fecal samples was carried out. Subsequently, differences...
Drögemüller M, Fouché N, Wyler M, Gurtner C, Meister SL, Neuditschko M, Jagannathan V, Gerber V, Leeb T.Hypertriglyceridemia (HTG) may be inherited and caused by variants in genes encoding enzymes of lipid metabolism. This study was prompted by the observation of eight Franches-Montagnes (FM) foals showing elevated plasma triglyceride levels and episodes of fatal acute pancreatitis. We termed this phenotype hypertriglyceridemia-induced pancreatitis (HIP). The affected foals were distantly related and inbred to a prominent stallion suggesting autosomal recessive inheritance. Whole genome sequencing of an affected foal identified a homozygous loss of function variant in LMF1 encoding lipase matura...
Valenchon M, Reigner F, Lefort G, Adriaensen H, Gesbert A, Barrière P, Gaude Y, Elleboudt F, Lévy I, Ducluzeau C, Dupont J, Lainé AL, Uszynski I....Social interactions shape both the physiological and behavioural development of offspring, and poor care/early caregiver loss is known to promote adverse outcomes during infancy in both animals and humans. How affiliative behaviours impact the future development of offspring remains an open question. Here, we used Equus caballus (domestic horse) as a model to investigate this question. By coupling magnetic resonance imaging, longitudinal biobehavioural assessments and advanced multivariate statistical modelling, we found that prolonged maternal presence during infancy promotes the maturation o...
