Methods

In various parts of the world, normal oleic peanut meal is utilized as a common protein source for feeding livestock. However, few studies have examined how feeding high oleic (HO) peanuts to egg-producing hens and poultry may alter the fatty acid profile of the eggs produced. This study examined the effects of feeding a HO peanut diet to hens on the nutritive value, lipid, and fatty acid composition of the eggs produced.Hens were fed either a HO peanut meal + corn diet or a soybean meal + corn diet for 10 weeks. Egg samples were analyzed for fatty acids as well as beta-carotene (vitamin A), saturated fat, and cholesterol.

Key Findings

Main findings:• Yolk color value was significantly greater in the hens fed HO peanut diet, compared with hens fed the soybean diet.• Beta-carotene levels were significantly greater in eggs produced from hens fed HO peanuts compared with hens fed soybean.• Total saturated fat was significantly lower in the eggs produced from hens fed HO peanuts vs those who were fed soybean.• All egg samples were tested for the potential of peanut allergy transference. All of the eggs were found to be non-allergenic.
