Rumen-Protected Betaine Improves Meat Quality in Tibetan Sheep by Influencing Intramuscular Fat Deposition, Antioxidant Capacity, and Fatty Acid Composition
Background: Intramuscular fat (IMF) is a key determinant of meat sensory quality, but the effects of rumen-protected betaine (RPB) on IMF deposition in Tibetan sheep remain unclear. Methods: Sixty male, 3-month-old Tibetan lambs (Initial weight 17.72 ± 1.36 kg) were randomly assigned to a control (basal diet, n = 30) o...
