Values for time to first delivery and dam weight at sacrifice are given as mean ± SE.

^aRatio of males to females.

^bTwo dams died at 8 months of age, before the end of the study; the cause of the deaths could not be established.

^cThree dams died (two dams at 3 months and one dam at 8 months of age) before the end of the study; the cause of the deaths could not be established.
