Validation of the Energy Matrix of Guanidinoacetic Acid for Broiler Chickens: Effects on Performance, Carcass Traits, and Meat Quality

Excellent work done, several points clarified, the importance of ADA well explained, oils come with a negative attribute, the rancidity, high FFA content, that affect the birds performance, to counter adding of antioxidants adds to expenses and interfere with birds metabolism. Continue the good work, in the interest of the poultry industry.

Dear Ms. Valentine et al. A very nice study, validating previous experiments reported that confirmed maintenance of performance whilst reducing costs. Energy is invariably the most expensive nutrient in least cost rationing, so any tool available will help to improve profitability. I am particularly interested also in the impact GAA has on reducing oxidative stress, by improving mitochondrial efficiency and therefore potential electron leakage, leading to excess ROS generation.
