Thus, with the aim of evaluating ruminal biohydrogenation
, Schmidely et al.
The processing of concentrated feeds via thermal treatments, as the pelleting, is an alternative method to protect canola PUFA from ruminal biohydrogenation
, and to improve nutrient digestibility of the diet (Neves et al.
Ruminant CLA comes from two sources: one from biohydrogenation
in the rumen, and the other from the synthesis of C18:1 trans-11 by the activity of [DELTA]9-desaturase in animal tissues (Griinari et al.
Diet, rumen biohydrogenation
and nutritional quality of cow and goat milk fat.
During the biohydrogenation
process, isomeriation reactions convert cis bounds into trans bounds before the beginning of the reduction reactions which add hydrogen to the double bounds.
Effect of fish oil on in vitro rumen lipolysis, apparent biohydrogenation
of linoleic and linolenic acid and accumulation of biohydrogenation
Evidence for the inhibition of the terminal step of ruminal a-linolenic acid biohydrogenation
by condensed tannins.
1997; Bateman and Jenkins, 1998) and citrus pulp seems to have interfered with ruminal biohydrogenation
, thus resulting in incomplete processes that produce trans-18:1 FA isomers.
Effect of lipid supplements on ruminal biohydrogenation
intermediates and muscle fatty acids in lamb.
As the result of biohydrogenation
of linoleic acid in the rumen and synthesis of CLA from trans-9-C18:1 in the mammary gland, milk cis-9,trans-11-CLA significantly increased in the LSO and WLS diets (1.
The composition of fatty acids in meat is the result of lipogenesis in adipose tissue and dietary lipids and subsequent ruminal biohydrogenation
(Berchielli et al.
The major MUFAs are C18:1 followed by palmitoleic (C16:1) and vaccenic acid (trans11-18:1), the products of incomplete biohydrogenation
of 18:2n-6 and 18:3n-3 in the rumen.
