Abstract
. An ovine modelwas used in the present study because of similarities with human reproductive physiology and embryogenesis. The aim of the study was toinvestigate the effect of maternal nutrient (protein) restriction during early or late gestation on young adult body composition andmetabolism.Nineteen Scottish Blackface ewes were synchronised and mated with Scottish Blackface rams. Three different maternal dietary regi-mens were established: control, 180gprotein/kg from day 0 (mating date) to term (approximately 145d gestation; CP; n 6 (four males,two females)); low-protein early, 90gprotein/kg from day 0 to day 65 then 180gprotein/kg from day 66 to term (LPE; n 7 (two males,Þve females)); low-protein late, 180gprotein/kg from day 0 to day 65 then 90gprotein/kg from day 66 to term (LPL; n 6 (two males, fourfemales). All maternal diets were isoenergetic and were fed as concentrate supplemented with hay. Animals were scanned on day 70 andmaternal dietary allowance adjusted according to fetal number and gestational age (according to Agricultural and Food Research Councilguidelines
