• Factors affecting odd- and branched-chain fatty acids in milk: A review (2006, background): “In contrast, Wachira et al. (2000) reported that dietary inclusion of fish oil decreased microbial protein synthesis.”
• Intestinal flow and digestibility of trans fatty acids and conjugated linoleic acids (CLA) in dairy cows fed a high-concentrate diet supplemented with fish oil, linseed oil, or sunflower oil (2005, background): “In another study, feeding fish oil compared with linseeds to sheep resulted in greater intestinal digestibility of 14:0, 16:0, cis9-16:1, 18:0, EPA, and DHA (Wachira et al., 2000).”
• Feeding strategies to design the fatty acid profile of sheep milk and cheese (2014, background): “Unfortunately, the enhancement of PUFA omega-3 long-chain fatty acids (LC-PUFA) such as EPA and DHA in milk by the diet is difficult because of the high level of biohydrogenation of these FA in the rumen, which has been estimated to be 72% for DHA in sheep (Wachira et al., 2000).”
• Nutritional manipulation of the fatty acid composition of sheep meat: a review (2007, background): “The level of biohydrogenation of ruminally unprotected dietary sources of 18:2nx6 and 18:3nx3 has been consistently reported to be in the region of 900–950 g/kg when determined in sheep (Wachira et al. 2000; Chikunya et al. 2004) or in vitro (Sinclair et al. 2005b).”
• Fish oils as potent rumen methane inhibitors and associated effects on rumen fermentation in vitro and in vivo (2003, background): “Nevertheless, fish oil (FO) supplementation has been reported to increase rumen propionate concentrations (Shaw and Ensor, 1959; Sutton et al., 1975; Doreau and Chilliard, 1997; Keady and Mayne, 1999; Wachira et al., 2000), suggesting reduced rumen methanogenesis (Van Nevel et al.”
• NEW PERSPECTIVES ON LIPID DIGESTION AND METABOLISM IN RUMINANTS (2003, background): “For example, dietary supplements of fish oil appear to inhibit the last step of biohydrogenation because they increase rumen outflow of trans 18:1 fatty acids and reduce the outflow of stearic acid (Wachira et al., 2000; Shingfield et al., 2003).”
