Table 5. The effect of dietary marine derived Ca-Mg complex supplementation to gestating and lactating sows in four successive parities on fecal score before and after farrowing¹⁾

Items	Parity 1			Parity 2			Parity 3			Parity 4			SEM	p-value
	CON2)	CM1	CM2	CON	CM1	CM2	CON	CM1	CM2	CON	CM1	CM2		Parity	Treatment	P × T
Before farrowing	2.27	2.25	2.25	2.27	2.24	2.25	2.24	2.25	2.24	2.21	2.21	2.24	0.020	NS	NS	NS
After farrowing	2.31	2.29	2.29	2.32	2.29	2.29	2.28	2.31	2.30	2.28	2.30	2.30	0.021	NS	NS	NS

Values represent the means of 24 sows per treatment.
Fecal score data before and after farrowing were also analyzed using chi-square test. The fecal score before and after farrowing were found to be non-significant during all four subsequent parities.
Fecal score: 1, hard, dry pellet in a small, hard mass; 2, hard, formed stool that remains firm and soft; 3, soft, formed, and moist stool that retains its shape; 4, soft, unformed stool that assumes shape of the container; 5, watery, liquid stool that can be poured.
CON, basal diet; CM1, Basal diet – MgO - 0.3% limestone + 0.40% marine derived Ca-Mg complex; CM2, basal diet - MgO - 0.7% limestone + 0.40% marine derived Ca-Mg complex.
P × T, interactive effects between parity and dietary treatments; NS, non-significant.
