Recall from the discussion of additives in Chapter 3 that ionophores are products that increase the efficiency with which ruminants are able to use feed energy to meet their maintenance energy needs.
Those used purely in animals--such as ionophores, which improve feed efficiency in sheep and cattle but are too toxic for use in people--are of little concern.
Another alternative is the use of ionophores that, in addition to improving energy metabolism, reducing the ruminal degradation of dietary protein, increasing the digestibility and milk production, also reduce SFA and increase CLA content in the milk of dairy cows (Duffield et al.
It is similar to that observed with ionophores in rumen fermentation.
