Poultry Farming Study Reveals New Findings on Effects of Naringin on Hatchability and Growth Performance in Broiler Chicks

Strategic Insights

— 1 min read

Researchers at Afyon Kocatepe University have conducted a study on the effects of in ovo injection of naringin on hatchability, antioxidant status, intestinal morphology, and growth performance in broiler chicks. The study found that naringin, a flavonoid derived from citrus, enhanced chick development, intestinal health, and antioxidant capacity when administered before hatching. The results of the study could have significant implications for South African poultry science, particularly in the search for natural, growth-promoting alternatives to antibiotics.

Key Takeaways:

  • The study used a total of 180 fertilised Ross 308 broiler eggs, which were randomly assigned to control, negative control, and naringin treatment groups.
  • The hatchability rates of the eggs in the control, negative control, and naringin treatment groups were 83.3%, 80%, and 88.3%, respectively, indicating that 15 mg naringin provided a 6% increase in hatchability.
  • In ovo injection with naringin insignificantly decreased hatchling weight, while significantly increasing hatchling length and insignificantly increasing hatchability compared to the control group.
  • The study concluded that additional research is needed to determine the most effective naringin level to obtain optimum results from in ovo injection during the incubation process.
  • Pesmen's study (2025) provides valuable insights for South African poultry science, particularly in the search for natural, growth-promoting alternatives to antibiotics.
  • The research concluded that this study is relevant for South African producers seeking sustainable strategies to improve poultry health and productivity while complying with evolving regulations on antibiotic use.

Statistics:

  • 180 fertilised Ross 308 broiler eggs were used in the study.
  • The hatchability rates of the eggs in the different treatment groups were:

+ Control: 83.3%

+ Negative control: 80%

+ Naringin treatment: 88.3%

  • The hatchling weights were:

+ Control: 46.26 g

+ Negative control: 46.83 g

+ Naringin treatment: 46.56 g

  • The hatchling lengths were:

+ Control: 16.95 cm

+ Negative control: 17.17 cm

+ Naringin treatment: 17.28 cm
