Dietary lipids are potent modifiers of rumen fermentations.
Their use may offer a nutritional strategy
to reduce protozoal predation and intraruminal
recycling of bacterial protein. In this way, the efficiency
of dietary protein utilisation and mitigating N
losses may be improved in ruminants (Hristov and
Jouany, 2005). Feeding an animal with vegetable
oils such as soybean oil is potential to reduce methanogenic
bacteria and methane production (Mao
et al., 2010).
