DES was administered subcutaneously.

^aThe ME value for RM1 was taken from the manufacturer’s data sheet.

^bTotal energy intake was calculated as the product of the total amount of food consumed per rat over the duration of the study and the ME of the diet.

^cMean ± SD.

^dUterine weights adjusted for covariance with terminal body weights.

*p < 0.05 and

**p < 0.01 compared with RM1 or RM1/AO control.

^#p < 0.01 compared with RM1/ANT control.
