摘要

This study was conducted to evaluate the effect of dietary antioxidant on broiler meat quality, especially focused on PSE (pale color, soft and exudative), under chronic heat stress condition. 28 days old female Ross broilers were kept in independent cages with controlled temperature of 24 °C (normal temperature: NT) or 30 °C (heat stress: HS). The chickens of NT were fed basal feed that was adequate requirement of NRC (1994). The chickens of HS were fed basal feed (HS) or Vitamin E (200IU/kg) added feed (HS+E). Diets and water were provided ad libitum. Broilers were weighted and slaughtered at 38 days old. The pectoral muscle was removed immediately and stored at 4°C until determination of meat color, pH, water holding capacity (WHC) and share force value (SFV). Furthermore contents of free amino acids and peptides of meat were also measured. Body weight gain and feed intake was decreased in HS groups compared with NT. The pH values of meat were tend to decrease in only HS group on just after slaughtered. After 2 days of storing, SFV was significantly decreased in HS, but there was no difference between NT and HS+E. Content of free carnosine were decreased in HS and HS+E compared with NT. These results describe that dietary antioxidant ameliorate the degraded meat quality by heat stress.
