Table 2.

Main effects of fescue seed treatment (endophyte-infected, E+ or endophyte-free, E−) and stage of gestation (MID, day 35 to 85 or LATE, days 86 to 133) on fetal number and sex at day 133 of gestation¹

Stage of gestation	MID		LATE
Fescue seed treatment	E−	E+	E−	E+	SE
Number of pregnant ewes	16	16	16	16
Number of fetuses	28	31	29	30
Fetal number/ewe	1.75	1.94	1.81	1.88	0.55
Fetal sex2	1.50	1.52	1.43	1.59	0.49

¹The interaction between fescue seed treatment and stage of gestation was nonsignificant (P > 0.54).

²Fetal sex: 1 = male, 2 = female.
