Summary
This 2024 study evaluated the nutritional performance and metabolic effects of broilers fed genetically modified soybean variety DP-305423-1, examining both productive outcomes and lipid biochemistry. The research measured growth performance, carcass and meat fatty acid profiles, and hepatic fatty acid metabolism markers to assess whether this GM soybean variety influences broiler lipid deposition and metabolic pathways. The findings contribute to the safety and nutritional assessment data for this GM crop in poultry feed systems.
Regional applicability
UK poultry producers would have limited direct applicability, as UK regulations require clear labelling of GM feed ingredients and some retailers/producers avoid GM inputs; however, the metabolic and nutritional data may inform feed formulation standards and GM crop assessment processes used by UK food standards authorities.
Key measures
Broiler body weight gain, feed conversion efficiency, meat fatty acid composition (saturated, monounsaturated, and polyunsaturated fatty acids), liver fatty acid metabolism markers (likely including lipogenic and oxidative enzyme activity or expression)
Outcomes reported
The study assessed growth performance, carcass composition, fatty acid profiles, and hepatic markers of lipid metabolism in broilers fed diets containing genetically modified soybean DP-305423-1. Key measurements included body weight gain, feed conversion ratio, breast and thigh meat fatty acid composition, and liver gene expression or enzymatic markers related to fatty acid synthesis and oxidation.
