Overall objective
- To investigate synergistic effects of butyrate glycerides with plant extracts to promote chicken growth performance and to control necrotic enteritis in chickens.
Outcomes
- Bird on 0.75% brown seaweed (Tasco) had the highest body weight followed by the medicated birds and the birds on 1.0% Tasco on day 35, suggesting that Tasco can promote broiler growth performance.
- No synergic effects of butyrins with seaweed (Tasco) were observed.
- No synergic effects of butyrins were observed with encapsulated oil product (NE-OFF) at the tested level.
- No growth performance was affected by the combination of butyrinsand cranberry pomace.
- The results suggests that Tasco could be fermented in the chicken gut.
Application
The research suggests that brown seaweed (Tasco) can:
- Support bacterial growth after the treatment with simulated stomach and intestinal fluids, suggesting the possibility of in vivo fermentation of Tasco.
- Improve broiler growth performance.
