Figures & Tables

Sperm with normal structure (A) and sperm with the Dag defect (B).

Table 1

Formulae used to calculate sperm head morphometric measurements

Variable	Formula
Head length (μm)	L
Head width (μm)	W
Head perimeter (μm)	P
Head area (μm²)	A
Head ellipticity	L/W
Head elongation	(L−W)/(L+W)
Head roughness	4π(A/P²)
Head regularity	π(L×W/4×A)

Frequency of sperm with the Dag defect in Duroc boars by age

Table 2

Morphometric parameters of boar sperm measured manually with MultiScan software

Morphometric parameter	Sperm with normal structure	Sperm with Dag defect
Head length (μm)	8.29^a ± 0.33	7.97^b ± 0.32
Head width (μm)	4.26^a ± 0.19	4.07^b ± 0.18
Head perimeter (μm)	23.39^a ± 0.98	22.29^b ± 0.64
Head area (μm²)	27.79^a ± 1.17	25.29^b ± 0.95

[i] Different superscript letters designate significant differences between means within rows at P ≤ 0.05
