Omega-3s and broiler heart health

Summary

The effectiveness of canola oil, an omega3 containing vegetable oil, for increasing the broiler heart content of the ‘fishtype’ omega3 fatty acids, known as EPA and DHA, will be examined. Canola oil will be compared with the fat in commercial diets and with fish oil. The rationale relates to prevention of Sudden Death Syndrome (SDS) in broilers. EPA and DHA have cardiac antiarrhythmic effects in rats, dogs, marmosets and humans. Therefore, they will most likely have the same effects in chickens. The proposed benefits relate to decreased SDS which is most likely due to cardiac (ventricular) arrhythmia secondary to heart failure. Although fish oil could be used to elevate cardiac EPA and DHA in broilers, this is neither practical nor sustainable for several reasons. Therefore, canola oil will be examined. A positive result would provide the basis for a larger study that examined the vegetable omega3 approach for decreasing SDS incidence. However, that is beyond the scope of the present proposal. A beneficial side effect is expected to be an increase in chicken meat EPA and DHA which can be used to promote benefits of omega3 chicken to human health.

Objective Summary

The overall longer term GOAL is to decrease SDS (and ascites) in broilers by using vegetable oils to increase the fishtype omega3 content of chicken heart in a manner which has long term sustainability. Note that there would be no increase in the total fat content of chicken meat with this proposal. The specific AIMS of this project are: To examine the effects of canola oil, relative to fish oil and standard commercial fat, on cardiac EPA and DHA – this is a proofofconcept study which, if successful, could lead to a larger study with clinical outcomes such as SDS.
