¹ Probability of significant factorial effects. Effects tested were as follows: Oil = flaxseed oil supplementation; Vit. E = vitamin E supplementation; Interaction = interaction between flaxseed oil and vitamin E. NDF = neutral detergent fiber; ADF = acid detergent fiber; IVDMD = in vitro dry matter digestibility [16].
