Hypothesis
Nannochloropsis oceanica, due to its n-3 PUFA and protein contents, will be well digested by weaner piglets and will thus be a suitable feedstuff for such animals when its price becomes competitive.
Conclusion
The study found that incorporating Nannochloropsis oceanica in piglet diets decreased the digestibility of certain nutrients but did not negatively affect the gastrointestinal health of the piglets.
Supporting Evidence
- The digestibility of dry matter, organic matter, and gross energy decreased with higher levels of Nannochloropsis oceanica.
- Nitrogen intake increased linearly with Nannochloropsis oceanica inclusion.
- Volatile fatty acid concentrations decreased linearly with increasing dietary inclusion of Nannochloropsis oceanica.
- The study provides the first nutritional characterization of Nannochloropsis oceanica for weaner piglets.
Takeaway
This study looked at how well piglets can digest a type of algae called Nannochloropsis oceanica, which could be a good food for them if it becomes cheaper.
Methodology
Twenty-four male piglets were randomly allocated to four dietary treatments with increasing levels of Nannochloropsis oceanica, and their digestibility was measured over two weeks.
Limitations
The study was short-term and focused on digestibility, which may not fully represent long-term effects on growth and health.
Participant Demographics
Male piglets weaned at 28 days of age.
