Influence of maternal XXXX on fetal development in @entity1707 .

@entity1707 @entity28 @entity1674 @entity73326 @entity1718
Fetuses from linebred lean (L) and @entity28 (O) and reciprocal crossmatings were examined at 110 d of gestation for line, maternal and heterotic effects. There was no significant heterotic effect for any trait measured. A significant maternal effect was observed for adipose tissue @entity73326 ( @entity73326 ) activity and for serum @entity1674 . The enzyme activity and @entity1674 concentration were higher in fetuses from O dams than in fetuses from L dams. In a lipid clearance test, no maternal effect was observed for changes in serum concentrations of @entity1674 and free @entity1718 or in optical density (associated with the disappearance of injected Liposyn). Linebred O fetuses exhibited higher @entity73326 activity in both the biceps femoris muscle and sc adipose tissue compared with linebred L fetuses. The @entity73326 activity of the adipose tissue was higher than that of the skeletal muscle. The percentage of dry matter, percentage of @entity1674 and protein/DNA were higher in the muscle of linebred O fetuses than in that of linebred L fetuses. Based on tissue @entity73326 activity and on muscle compositional traits, linebred O fetuses were more mature at 110 d of gestation than were the linebred L fetuses. @entity28 had little detectable influence on fetal development of the @entity1707 when measured at 110 d of gestation.
