N There is limited information on the
effects and requirements of specific fatty acids for the calf. Although
calves consume high-fat milk or milk replacer-based diets (≥۲۰% fat, DM
basis) initially, their diet is typically very low in fat once weaned
(NRC, 2001). No estimates of requirements exist for specific fatty acids
or groups of fatty acids (NRC, 2001). Recently, it was demonstrated
that supplementing the milk replacer with sources of C18:2 and C18:3
increased ADG and reduced days with scours (Hill et al., 2007a,b).
Additionally, supplementing the starter with sources of C18:2 and C18:3
was shown to increase ADG and feed efficiency in calves up to 4 mo old
(Hill et al., 2007c)
