Effect of areca nut extracts on growth performance, slaughtering performance, and meat quality of broiler chickens.

Introduction: Since the comprehensive ban on the addition of antibiotics to livestock and poultry feeds in China, the search for safe and natural antibiotic substitutes has become a hot spot in the animal breeding industry. Areca catechu L (AN), known as the leader among the four southern medicinal herbs, possesses functions such as insecticidal, antibacterial, antiinflammatory, promoting gastrointestinal motility and preventing Alzheimer's disease. Nevertheless, ANE is rarely used as a feed additive in AA broilers, and its specific role remains unclear. This study was conducted to investigate the effects of different levels of areca nut extracts (ANE) on growth performance, slaughter performance and meat quality of AA broiler chickens. Methods: 128 one-day-old Arbor Acres broilers were randomly divided into eight groups of 16 birds each, housed in three cages with 5-6 birds per cage, with or without ANE supplementation (0, 100, 150, 200, 250, 300, 350, and 400 mg/kg, respectively). Results: The entire experiment duration was 49 days. Adding 100 and 200 mg/kg ANE to the diet could significantly increase the body weight of broilers at 21 days of age ( Discussion: In conclusion, An appropriate amount of ANE in the diet has been demonstrated to boost the growth performance and meat quality of broilers, facilitate muscle development, and has no remarkable influence on slaughter performance. the ideal dosage for broilers is 100-200 mg/kg ANE. The findings of this study offer valuable insights into the potential benefits of ANE in poultry production, and provide a basis for further research into the development of ANE as a new feed additive.
