“…hydrochloric acid (200: 100:1, v/v) to remove the fatty acids (Folch, Lees & Sloane Stanley, 1957;Wuthier, 1968). The fatty acids were converted to their methyl esters (Morrison & Smith, 1964), purified by preparative thinlayer chromatography (Body, 1975) and analysed by gas-liquid chromatography using programmed operating temperatures (Body & Hansen, 1978). Under operating temperatures between 160 and 275 °C at 4 °C/min the entire range of C 14 -C 32 fatty acids can be analysed in about 1 h.…”

The organic matter (OM) intakes of grazing ruminants can be calculated from the digestibility of the OM and faecal OM outputs which in turn are determined indirectly by administering known amounts of indigestible markers such as Cr2O3 (Langlands, 1975). The possibility that the C19–C32 fatty acids in fresh herbage could be suitable as an indigestible marker for determining intakes of grazing animals was examined. An early report had shown that when ‘Grasslands Ruanui’ perennial ryegrass (Lolium perenne L.) was fed fresh to sheep the C19–C32 fatty acids appeared not to be absorbed because their concentration increased from 7·2% of the total dietary fatty acids to 23·9% of the total faecal fatty acids (Body & Hansen, 1978).

“…Samples (1 g) of fats and the corresponding diets were extracted with chloroform/methanol (Folch, Lees & Sloane-Stanley, 1957), methylated (Morrison & Smith, 1964) and analysed by GLC on both polar (10% EGSS-X) and non-polar ( 3 % APL) columns (Body, 1975). Fatty acids were identified by comparison with authentic standards run under identical conditions.…”

Ruminants have extremely low concentrations of polyunsaturated acids in their adipose tissue as a result of hydrogenation of dietary lipids by microbes in the rumen. The possible association between intake of ruminant products high in ‘saturated’ lipids and the incidence of atherosclerosis in man has stimulated research on procedures for altering the fatty acid composition of ruminant tissue lipids. Vegetable oils, emulsified with a protein, spray-dried, and treated with formaldehyde, have been found to be protected from hydrolysis and hydrogenation in the rumen (Cooket al.1970; Scott, Cook & Mills, 1971). Their subsequent digestion in the small intestine, and absorption of the fatty acids by the animal, results in tissue lipids high in linoleic acid (Faichneyet al.1972; Faichney, Scott & Cook, 1973; Cooket al.1972; Garrettet al.1976).
