چکیده انگلیسی
This experiment was conducted to evaluate the effects of increasing dietary levels of peroxidized maize oil on growth performance and antioxidant status of nursery pigs. Weanling barrows (n = 128; initial body weight (BW) = 6.3 ± 1.4 kg) were blocked by initial BW and assigned randomly to 1 of 32 pens. Within block, pens were assigned randomly to 1 of 4 dietary treatments: 90 g/kg unheated maize oil, 60 g/kg unheated maize oil +30 g/kg rapidly peroxidized (RO) maize oil, 30 g/kg unheated maize oil +60 g/kg RO maize oil, or 90 g/kg RO maize oil. Diets were formulated to contain identical levels of total maize oil and standardized ileal digestible Lys to metabolizable energy (ME) ratios. Maize oil was heated for 12 h at 185 °C (air flow rate = 12 L/min) to yield RO (PV = 5.7 meq O2/kg; thiobarbituric acid reactive substances = 26.7 mg malondialdehyde eq/kg) maize oil. A 3-phase feeding program (phase 1 = d 0-4, phase 2 = d 4-14, and phase 3 = d 14-35) was used, and average daily gain (ADG), average daily feed intake (ADFI), gain to feed ratio (G:F), and energetic efficiency (g ADG/MJ of ME intake) were determined. Serum was collected on d 0, 14, and 35 from 1 pig per pen that was subsequently harvested to obtain liver and heart tissue. Final BW (19.5 vs 18.5 ± 0.6 kg for 0 vs 90 g/kg RO maize oil; P < 0.15) and ADG (377.5 vs 347.0 ± 13.6 g for 0 vs 90 g/kg RO maize oil; P â¤Â 0.10) tended to decline linearly with increasing dietary RO, but ADFI was not affected. Consequently, G:F (P < 0.05) declined linearly by 1.4-4% with increasing dietary concentrations of RO maize oil. The α-tocopherol content of serum declined with increasing dietary concentrations of RO maize oil (linear and cubic; P < 0.01). These data suggest that RO maize oil negatively affects growth performance and the efficiency of energy utilization of nursery pigs linearly and reduces serum α-tocopherol content.
