Food resource allocation patterns in lactating females in a long-term selection experiment for litter size in mice [PDF]

, 2002
Resource allocation patterns, as quantified by residual food intake (RFI), and the consequences for offspring development were investigated during lactation in 96 females of a mouse line selected for 104 generations for high litter size at birth (S-line)
