Sustainable Goat Farming in Thailand: Research on Alternative Feed Source

Strategic Insights -

Research conducted at the Rajamangala University of Technology Srivijaya has shed light on the potential of using Azolla microphylla as a cost-effective alternative protein source in goat diets, aiming to replace soybean meal and improve production efficiency. The study involved 25 healthy crossbred Boer goats and found that Azolla microphylla can effectively replace up to 50% of soybean meal, reducing production costs and enhancing the efficiency of meat goat farming in southern Thailand. However, further research is needed to optimize dietary formulations and improve the nutritional profile of Azolla to maximize its potential as an alternative feed ingredient.

Key Takeaways:

  • Research conducted at the Rajamangala University of Technology Srivijaya explored the use of Azolla microphylla as a cost-effective alternative protein source in goat diets.
  • The study involved 25 healthy crossbred Boer goats and found that Azolla microphylla can effectively replace up to 50% of soybean meal.
  • Results indicated a significant decrease in crude protein and nutrient digestibility with increased Azolla inclusion, particularly at higher replacement levels.
  • Azolla microphylla reduced production costs and enhanced the efficiency of meat goat farming in southern Thailand.
  • The study suggests that Azolla microphylla can offer a sustainable strategy to reduce production costs and enhance the efficiency of meat goat farming in southern Thailand.
  • Further research is needed to optimize dietary formulations and improve the nutritional profile of Azolla to maximize its potential as an alternative feed ingredient.

Statistics:

  • 25 healthy crossbred Boer goats were used in the study.
  • The experiment involved five treatment groups with varying levels of Azolla (0%, 25%, 50%, 75%, and 100% replacing soybean meal) in a completely randomized design.
  • Data on feed intake, weight gain, nutrient digestibility, and rumen fermentation characteristics were collected over 90 days.
  • Results indicated a significant decrease in crude protein and nutrient digestibility with increased Azolla inclusion.
  • Azolla microphylla reduced ammonia nitrogen levels, suggesting altered protein metabolism.
  • Total volatile fatty acid concentrations peaked at the 25% Azolla level, indicating optimal fermentation efficiency.
