Effects of Added Dietary Fat on Fatty Acid Composition and Carcass Characteristics of Fattening Steers

Metabolism of Long-Chain Fatty Acids in the Rumen

“…Increasing the dietary lipids brings about an increase of stearic acid in depot fats (Edwards et al, 1961), and of oleic acid, in addition to stearic acid, in milk lipids (Brown et al, 1962). Such a difference in lipogenetic behavior between adipose tissue and the mammary gland was particularly stressed in the investigations of Tove and Mochrie (1963); these authors pointed out that the increase of stearic and oleic acids in milk is accompanied by a decrease of palmitic and myristic acids, while the increase of stearic acid in adipose tissues is concomi tant with the decrease of oleic acid.…”

Identification and utilization of genes associated with beef qualities

“…Microorganisms within the rumen hydrogenate a majority of the dietary unsaturated fatty acids and most dietary fatty acids are absorbed as saturated fatty acids (Jenkins 1993). However, it is known that diet also influence bovine fatty acid composition (Edwards et al . 1961; Cabezas et al .…”

“…Microorganisms within the rumen hydrogenate a majority of the dietary unsaturated fatty acids and most dietary fatty acids are absorbed as saturated fatty acids (Jenkins 1993). However, it is known that diet also influence bovine fatty acid composition (Edwards et al 1961;Cabezas et al 1965). Zembayashi et al (1995) demonstrated that adipose tissue of Japanese Black cattle contains a higher proportion of MUFA than that of Holstein, Japanese Brown cattle or Charolais.…”

Soaking of complete fattening rations high in poor roughage. 4. The effect on deposition and fatty acid composition of bovine fat

“…173 ruminant fat depots are not greatly influenced by the diet. However, with improved analytical techniques, especially gas liquid chromatography, it has been possible to demonstrate differences in fatty acid composition of ruminant adipose tissues caused by different diets (Edwards, Tove, Blumer and Barrick, 1961;Tove and Mochrie, 1963;Roberts and McKirdy, 1964;Bensadoun and Reid, 1965;Cabezas, Hentges, Moore and Olson, 1965). Church, Ralston and Kennick (1967), presenting their own data and reviewing the literature, showed that the fatty acid composition of ruminant tissue can be modified by nutritional methods.…”
