This study investigated replacing soybean oil with poultry fat in broiler chicken diets to assess its impact on performance, nutrient digestion, blood lipids, and muscle fatty acid content. Researchers fed 480 Ross-308 chicks diets where soybean oil was replaced by poultry fat at 25%, 50%, or 100%. The findings showed that substituting soybean oil with poultry fat did not negatively affect the birds' growth or carcass characteristics. However, diets with 50% and 100% poultry fat led to increased abdominal fat and improved dry matter digestibility. The fatty acid composition of pectoral muscle also changed, with reductions in some acids and increases in others. Importantly, using poultry fat significantly improved economic parameters, suggesting it is a viable and cost-effective lipid source for broiler diets.
Finding cost-effective and efficient feed ingredients is crucial for the poultry industry. This research offers a practical solution by demonstrating that poultry fat, a cheaper alternative to soybean oil, can maintain broiler growth and meat quality, potentially lowering production costs for farmers and consumers.
This research indicates that poultry fat can be directly incorporated into broiler feed formulations as a full or partial replacement for more expensive soybean oil. This could enable poultry feed manufacturers to produce more economical feed, leading to cheaper meat for consumers. The findings suggest this is an applied solution, ready for adoption in commercial broiler farming operations.

Continuous genetic improvements of commercial broiler strains has led to the necessity of using fats in their rations to fulfill a large portion of the energetic requirements. Several fat sources have been introduced in poultry nutrition, such as rendering poultry fat (PF) an available and cheap lipid source compared to conventional sources such as soybean oil (SO). The present study investigated the effect of partial or full replacement of SO by PF on performance, nutrient digestibility, blood lipids, and fatty acids (FAs) content of pectoral muscle. Four hundred and eighty one-day-old male Ross-308 chicks were distributed into four experimental groups (12 replicates each): the first group (control) was fed a diet formulated with soybean oil as a fat source while the second to fourth groups (PF25, PF50, and PF100) were fed diets formulated with 25, 50 and 100% of PF as a fat source instead of SO. Results revealed no synergistic effect between SO and PF in any of the studied parameters. Replacing SO by PF did not alter birds' growth, carcass characteristics, and plasma indices of birds. Abdominal fat% was increased (<i>p</i> < 0.01) in PF50 and PF100. Dry matter digestibility was improved (<i>p</i> < 0.05) in PF50 and PF100, while crude fat and protein digestibility was not affected. Contents of palmitic and docosahexaenoic acids in the pectoral muscle of PF50 and PF100 were reduced (<i>p</i> < 0.01) while concentrations of oleic and linolenic acids, total unsaturated FAs, and polyunsaturated FAs/Saturated FAs ratio were elevated (<i>p</i> < 0.05) in the same groups. Liver thiobarbituric acid reactive substances (TBARS) and muscle vitamin E contents were not altered. The dietary addition of PF greatly improved economic parameters. In conclusion, PF can be used as a lipid source in broiler diets to produce inexpensive meat while maintaining its growth performance.
