Short summary
The purpose of our study was to investigate whether glutamine and L-carnitine could be used as anti-cold stress nutrients to alleviate the adverse effects of cold stress on newborn broilers. Broilers were respectively fed with different levels of glutamine and L-carnitine according to the L16 (45) orthogonal experimental design for 3 weeks. Their interaction occurred and improved the growth performance, nutritional status and cold stress response of broilers at low temperature.
