Optimizing Poultry Farming through Fermented Soybean Meal

Strategic Insights -

Researchers at Universitas Sebelas Maret, Surakarta, Indonesia, have conducted a study on the effects of fermented soybean meal on nutrient digestibility and carboxymethyl cellulase activity of Jawa Super chickens. The study aimed to improve the nutritional value of soybean meal, which is a primary source of amino acids in poultry feed. The experiment involved 36 one-day-old Joper male chicks that were randomly allocated into three dietary treatments: a control group without fermented soybean meal, and two treatment groups that received fermented soybean meal with either Aspergillus niger or Bacillus subtilis. The results showed significant improvements in crude protein, dry matter, and nitrogen-free extract digestibility in the treated groups, with Bacillus subtilis demonstrating slightly better performance than Aspergillus niger.

Key Takeaways:

  • The study found that fermented soybean meal improved nutrient digestibility in Jawa Super chickens, particularly in crude protein, dry matter, and nitrogen-free extract.
  • The results demonstrated significant differences in nutrient digestibility between the control and treatment groups, with P ≤ 0.05.
  • Bacillus subtilis showed slightly better performance in nutrient digestibility and carboxymethyl cellulase activity compared to Aspergillus niger.
  • The study provides evidence that fermented soybean meal can be an effective tool for optimizing poultry farming, particularly in terms of improving nutrient digestibility and carboxymethyl cellulase activity.
  • The researchers suggest that feeding Joper chickens with fermented soybean meal can achieve optimal digestibility of nutrients, especially in crude protein.
  • The study indicates that the use of fermented soybean meal can lead to improved growth performance in poultry, particularly in terms of nutrient digestibility and carboxymethyl cellulase activity.

Statistics:

  • 36 one-day-old Joper male chicks participated in the study.
  • The study lasted from November 2022 to January 2023.
  • The results showed significant differences in nutrient digestibility between the control and treatment groups, with P ≤ 0.05.
  • The study found significant improvements in crude protein (28.3% to 34.5%), dry matter (24.1% to 29.2%), and nitrogen-free extract (14.5% to 17.1%) digestibility in the treated groups.
  • Bacillus subtilis demonstrated slightly better performance in carboxymethyl cellulase activity (43.5% to 49.8%) compared to Aspergillus niger (38.2% to 43.2%).
