Effects of stock density on bone mineral density of laying hens.¹

	Stock density (birds/m2)
Items	5	6	7	10	SEM2	P-value
BMC3, g	3.76	3.85	3.85	3.18	0.491	0.50
BMD4, g/cm2	0.28a	0.28a	0.29a	0.22b	0.030	0.03

^a,bValues in row with no common superscripts letter are significantly different (P < 0.05).

¹Data are least squares means of 5 observations per treatment.

²Pooled error of mean.

³BMC = bone mineral contents.

⁴BMD = bone mineral density.
