“…In human metabolism, they are best studied as components of skin lipids. Overall, several dozen specific BCFA, are found in milk and tissue of ruminants including sheep and goats, presumably synthesized by ruminal organisms that rely on them for membrane lipids [8, 9]. BCFA are conveniently categorized as mono- and di-/multi-methyl BCFA; in monomethyl BCFA, the predominant branching is at the terminal methyl ( iso ) or next to the terminal methyl ( anteiso ), as shown in Fig.…”

Branched chain fatty acids (BCFA) have recently been shown to be a major component of the normal human newborn gastrointestinal tract and have long been known to be a component of human milk. Ruminant food products are major sources of fat in the American diet, but there are no studies of milkfat BCFA content in retail milk. We report here the profile and concentrations of BCFA in a representative sampling of retail milk in the 48 contiguous United States (US), and their estimated intake in the American diet. Conventionally produced whole fluid milk samples were obtained from 56 processing plants across the contiguous 48 states. Retail milk samples contain exclusively iso-and anteiso-BCFA with 14-18 carbons. BCFA were 2.05 ± 0.14%, w/w of milkfat fatty acids (mean ± SD), and anteiso-BCFA comprised more than half this total. Based on these data and USDA food availability data, the average per capita BCFA intake of Americans is estimated to be about 220 mg/d from dairy; if current dietary recommendations were followed, BCFA intake would be about 400 mg/d. Adding intake from beef consumption, these estimates rise to approximately 400 and 575 mg/d, respectively. These results indicate that BCFA intake is a substantial fraction of daily fat intake, in amounts exceeding those of many bioactive fatty acids.

“…This result is similar to other studies that found only branched fatty acids with more than 11 carbon atoms (22). The most abundant branched fatty acids were those of 15 atoms in the carbon chain, similar to what was reported in previous works (23).…”

The aim of this research was to study the effects of seasons (rainy and dry) on the composition of the fatty acids (FAs) in milk of Creole goats in a semiintensive production system. Milk sampling was carried out in the dry season (June) and just after the rainy season (November) in an arid region of Baja California Sur, Mexico. The goat diet was composed of native species it grazed on in the rangeland, as well as hayed forages with some supplements containing approximately equal amounts of sorghum and maize. The results for different types of FAs in goat milk showed that there were no significant differences in saturated, polyunsaturated, branched, and omega-6 FAs, with differences for monounsaturated and omega-3 FAs. In terms of individual FAs, the majority of changes were not significant. The FA constituents showed that significant differences existed for C12:0, C23:0, C14:1 n-5, C14:1 n-7, C18:1 n-9, C18:3 n-3 cis, C22:5 n-3, and C22:6 n-3, and 2 branched fatty acids, C12:0 iso and C15:0 anteiso. The rest showed a trend of higher quantities of FAs during the rainy season, but it was not significant. In conclusion, goat milk quality as measured by FAs is for the most part very similar year round, independent of seasons in this semiintensive production system.

“…High variability of milk fatty acid composition among different animals was also observed by Massart-Leen et al (1981) and Tomotake et al (2006). However we determined a lower proportion (9.85 vs. 10.66-12.03 g/100 g) of myristic acid (C14:0) in goat milk compared to literature values (Atti et al, 2006;Schmidely et al, 2005).…”
