Essential oils key in fight against antibiotic use.
Essential oils are a key solution to an alternative for antibiotic growth promoters (AGPs), this was shown by research carried out by US food giant, Cargill. But what do essential oils achieve that other non-medicated feed additives don’t?
Essential oils key in gut health support : Gut health is important in poultry production because the digestive system performs key functions essential to ensuring birds' optimum performance. The optimal gut function in 4 key areas are:1)Managing microflora for a well-balanced bacterial population. 2) Controlling immune function and inflammatory response 3)Maximising nutrient digestion and absorption
4 ) Improving the physical barrier against pathogens.
While all additives studied showed some benefit in these areas, Cargill researchers found that selected essential oil compounds, particularly those derived from thyme, cinnamon and oregano, had the most comprehensive effect on overall gut health. Benefits included antimicrobial activity, modulation of immune response, antioxidant activity, improvement of nutrient digestibility and stimulation of mucus production.
"Activity against pathogens": "Only essential oils have both a broad spectrum of activity against pathogens and a direct impact on digestive function," said Stephanie Ladirat, global technology lead for gut health additives in Cargill's animal nutrition business.
Essential oils were found to be particular efficient in conditions where intestinal infections such as Salmonellosis and Coccidiosis were present. They were also found to be a viable alternative to antibiotics as more than 85% of the results showed a minimal difference between the positive control (antibiotics) and essential oils.
The research also showed that essential oils are just one facet of a feeding programme that promotes ideal gut health and allows antibiotic reduction. Research findings support combining essential oils with organic acids to get maximum efficacy. "Cargill's local nutrition experts are working directly with poultry producers to develop customised, holistic feeding programmes encompassing nutrition, additives and farm management based on the study results," says Twan Van Gerwe, poultry R&D director in Cargill's animal nutrition business.
Feed conversion trials: Combined study results from 12 trials demonstrated that birds given Cargill's Promote Biacid Nucleus additive, which contains a proprietary mixture of 7 carefully selected essential oil compounds, in combination with an antibiotic-free diet, consistently improves body weight gain by 2% and feed conversion by 1.5%, producing a return on investment (ROI) of 5:1 for producers.
The research was reported in world poultry.
