Summary
Precaecal digestibility in sows is influenced by feeding methods. The isogravimetrical determination method is recommended for assessing additional feed digestibility, improving nutrient utilization accuracy.
Area of Science:
- Animal Nutrition
- Digestive Physiology
Context:
- Assessing nutrient digestibility in swine is crucial for feed formulation.
- Ileum cannulation is a common method for determining precaecal digestibility.
Purpose:
- To evaluate the impact of intake level, animal individuality, and additional feed proportion on precaecal digestibility determination.
- To compare different methods for assessing the digestibility of supplementary feeds in sows.
Summary:
- Precaecal digestibility values in ileum-cannulated sows were found to be method-dependent.
- Factors such as feed intake level and individual animal variation influenced the results.
- The isogravimetrical determination (exchange trial) method was identified as a reliable approach for additional feeds.
Impact:
- Provides a more accurate method for determining nutrient digestibility in swine.
- Informs feed formulation strategies to optimize nutrient absorption and animal performance.
- Contributes to improved feed efficiency and reduced environmental impact in pig production.
