Values are expressed as least square means ± SEMp. SEMp = pooled SEM; E1 = space allowance per animal (m²) = 0.033w^0.667, space allowance per animal ranged from 2.3 to 2.6 m²; E2 = space allowance per animal (m²) = 0.048w^0.667, space allowance per animal ranged from 3.4 to 3.9 m².

^a,b,cLeast squares means within a row without a common superscript letter differ (P < 0.05).
