Data represents mean±SE.
The letter shows that the transitional diet was provided.
The letter shows that the experimental diets were provided.
Different letters in the same row are significantly different in different animal groups at the 0.05 level of probability (p<0.05).
Different letters in the same row indicate differences approached significance (0.10>p>0.05) in different animal groups.
NBW, normal birth weight; C, control (chow diet); HF, high fat diet; LBW, low birth weight; HFHD, high fat dairy source.
