4th week	Mean ± SE	16.41 ± 0.39^a	16.12 ± 0.30^ab	15.95 ± 0.23^b	15.91 ± 0.24^b
	LSD	—	1.77^∗	0.81^NS	1.15^NS
	0.05 = 0.426
	t-test

Data are represented as mean ± SE. t-test values: ∗: significant at P < 0.05, ∗∗: significant at P < 0.01, and ∗∗∗: significant at P < 0.001. ANOVA analysis: within each row, means with different superscript (a, b, c, or d) are significantly different at P < 0.05, whereas means with the same superscript letters mean that there is no significant difference at P < 0.05. LSD: least significant difference; NS: nonsignificant.
