No remarkable changes were found for final LW and
LW change among the treatments (Table 3). The amount of
dietary fat did not affect LW of the steers over the course of
the trial; however, LW was increased at 1.11, 1.20, and 1.20
kg/d in the animals fed PO, PO/LSO, and LSO, respectively
(Table 3). Similarly, Noci et al. (2007) reported that 150 g/d
sunflower oil (SFO) and 150 g/d LSO supplementation did
not affected final LW and average daily gain (ADG). This is
partially because total net energy (Mcal/d) consumption
was balanced by treatment. Furthermore, He and
Armentano (2011) supplemented a mixture of flaxseed oil
and SFO at 5% of diet and reported no significant effects of
supplementation on DMI, body weight, ADG, and gain per
unit feed.
