Level (\({a}_{0}\)), environmental sensitivity (\({a}_{1}\)) and total additive (\({a}_{0}+{a}_{1}\)) variances for daily feed intake (DFI) for different probabilities of the occurrence of an environmental challenge. \(p\) is the environmental descriptor with \(p\) = 0 indicating non-challenging environmental conditions and \(p\) = 1 indicating highly challenging conditions
