Effects of heat stress and astaxanthin (Ax) on the blastocyst development of bovine embryos

Treatment		No. of ≥8-cell embryos	No. of replicates	Blastocyst development %(least square means ± SEM)
Heat	Ax	No. of ≥8-cell embryos	No. of replicates	Blastocyst development %(least square means ± SEM)
−	−	86	5	47.9 ± 5.2^a
−	+	94	5	44.2 ± 5.2^a
+	−	90	5	17.8 ± 5.2^b
+	+	91	5	38.5 ± 5.2^a

^a,bValues without common superscripts differ significantly (P < 0.05)
