Interpretive Summary: Soybean oil and soybean oil products, such as recycled restaurant grease, can be an important source of energy in swine and poultry feeding programs because they provide a concentrated source of energy compared to other feedstuffs used in feed formulation. Because recycled restaurant grease may have compounds which may reduce its digestibility or may elicit biochemical reactions in the body, a study was conducted to evaluate the effect of peroxidized soybean oil on pig and broiler performance, and on the correlation of various quality indices relative to animal performance. Data from this experiment indicate that p-anisidine value, a measure of total aldehydes in an oil, had the greatest inverse correlation with animal growth performance in both broilers and pigs. This information is important for nutritionists at universities, feed companies, and livestock production facilities for determining which quality factors of lipids need to be measured relative to their negative impact on animal performance, and provides a basis from which to assess the economic value of peroxidized oils compared to unperoxidized oils.

Technical Abstract: Soybean oil and soybean oil products, such as recycled restaurant grease, can be an important source of energy in swine and poultry feeding programs because they provide a concentrated source of energy compared to other commonly used feedstuffs. The caloric value of refined, deodorized, bleached soybean oil is well documented, but there is limited data on the impact of thermally processed (i.e., peroxidized) soybean oil on pig and broiler performance and on which quality factors associated with the peroxidized soybean oil are correlated to the reduction commonly noted in animal performance. The current study was conducted to evaluate the effect of thermally processing soybean oil at varying temperatures (45C, 67.5C, 90C, 135C, 180C, and 225C) on pig and broiler performance and the correlation of various quality indices relative to animal performance. Data from this experiment indicate that the p-anisidine value had the greatest inverse correlation with animal growth performance in both broilers and pigs; and that among the aldehydes identified 2-decenal and 2-undecenal were highly inversely correlated to animal performance suggesting that chain length and unsaturation level affects the toxicity of aldehydes. This information is important for nutritionists at universities, feed companies, and livestock production facilities for determining which quality factors of lipids need to be measured relative to their negative impact on animal performance, and provides a basis from which to assess the economic value of peroxidized oils compared to unperoxidized oils.
