摘要： The application of alfalfa powder (AP) in Tibetan sheep to explore its healthy effects and meat quality improvement potential has not been reported. Our study found that AP improved the growth performance, serum metabolism, and antioxidation of Tibetan sheep. The edible quality, sensory quality, and nutritional quality of longissimus dorsi (LD) were analyzed. We observed lower drip loss and hue angle of meat after AP supplementation. AP also increased the cooked meat percentage, pH(24h), a*(24h), chroma(24h), and the contents of protein and fat. The targeted metabolomics profiling revealed that the contents of essential amino acids and flavor amino acids in mutton increased by AP treatments. AP also promoted the deposition of MUFA and PUFA. Therefore, as a promising botanical supplement, AP has a positive effect on the growth, development, and body health of Tibetan sheep, and is also conductive to providing healthy and nutritious high-quality livestock products.
