Health conscious consumers are increasingly demanding more nutritional food
products. Farmers seeking to reach these consumers have developed alternative,
pasture-based systems of poultry production. Northeast Missouri farmers rear the
Cornish-Cross breed for meat production in pasture systems with access to
insects and legumes such as alfalfa that supplement grain diet. Nutritionists
such as Jo Robinson claim that grass-fed meats have cardiac, circulatory, and
anti-carcinogenic benefits. Others claim pastured poultry has increased levels
of essential vitamins A, D, E, and conjugated lineolic acids (CLAs). Reported
results from nutritional analysis will include calorie density data from bomb
calorimetry, fatty acid screen of CLAs from gas chromatography (GC), and vitamin
content data from high performance liquid chromatography (HPLC). Results from a
consumer survey will reflect consumer perception of pastured poultry. Complete
data on fatty acid and vitamin composition should reveal differences in the
nutritional quality and healthiness of conventional versus pasture reared
poultry.
