Difference between Lac1 and Lac3 rats in milk yield and pup growth. (a) Bar charts showing difference between Lac1 and Lac3 rats in milk yield at two different time points when the average body weights of their pups were 13 g and 29 g. The milk yield is defined in the Results section. Data from 128 pups nursed by 8 Lac1 and 8 Lac3 dams. Each dam nursed a litter of 8 pups for 1 h. (b) Line graphs showing the difference between the pups of Lac1 and Lac3 rats in their weight gain over the period of PND 0–15 (*: p < 0.05; **: p < 0.001; Student’s t-test). n: the number of pups. In this and the rest of the figures, values are shown as means (± SEM)
