Adequate management of replacement ewe lambs (F0) in dairy sheep farms during postnatal life may modify the germline cells, thus promoting transmission intergenerational effects to offspring (F1). To test this hypothesis, 18 newborn male (F1), either born from methionine-supplemented (F0 being fed ad libitum with a milk replacer supplemented 1 g methionine/kg DM) or not same no methionine added), were included present study. All F1 managed exactly way along whole lifespan order bring out differences caused by supplementation F0 dams. Our data show that dams suckling period did promote significant (p > 0.05) changes on feed intake, growth rate, efficiency fattening period. Moreover, meat chemical composition (proximal, fatty acid profile, and volatile compounds) was similar for both groups 0.05), but F1-MET presented higher redness hardness < when compared F1-CTRL lambs. The biochemical profile also highlighted serum creatinine calcium content be at least partially related quality traits observed. Overall, all these results suggest early causes permanent offspring. This has positive effects, such as achieving more attractive color lamb (F1) consumers, negative reduced tenderness.
