W. Waldroup, S. E. Watkins, E. A. Saleh] A study was conducted to compare the feeding value of two blended animal-vegetable fats having different levels of free fatty acids (FFA) but similar fatty acid profiles and unsaturated:saturated (U:S) fatty acid ratios. One contained 29.8% FFA (AV-LO), while the other contained 44.7% FFA (AV-HI). Poultry oil (PO) and corn oil (CO) were fed as reference standards. Diets had 4, 6, or 8% supplemental CO, adjusting nutrient levels to dietary energy. Other fat sources were substituted for CO on a wt/wt basis. Each treatment was fed to four replicate pens of fifty male broilers from day-old to 42 days of age. There were no significant differences between the two blended fat sources in body weight, feed utilization, calorie:gain ratio, or mortality at 21 or 42 days of age. Body weight of birds fed the two blended fat sources was significantly less than that of birds fed PO at 21 days, but did not differ significantly at 42 days of age. Results of this study indicate that blended animal-vegetable fats with fatty acid profiles and U:S ratios similar to PO resulted in similar performance; the FFA level of these blended fats did not adversely influence performance of the broilers. © 1995 Applied Poultry Science, Inc.
