Dietary tea tree (Melaleuca alternifolia) oil supplementation enhances the expressions of amino acid transporters in goat ileal mucosa and improves intestinal immunity.

ABSTRACT: Tea tree oil (TTO) is a plant-derived additive with anti-inflammatory, bactericidal, and growth-promoting properties. However, little is known about the effects of TTO on intestinal amino acid transport and immune function in goats. Twenty-four Ganxi goats (initial body weight of 13.5 ± 0.70 kg) were randomly allotted two treatments and fed either control (CON) or CON+TTO (0.2 ml/kg) diet. The addition of TTO to the diet significantly decreased (p < .05) tumor necrosis factor-α content and increased (p < .05) interleukin-2 (IL-2) content in goat serum; significantly decreased (p < .05) IL-12, and increased (p < .05) IL-2 content in goat ileal mucosa; significantly increased (p < .05) secreted IgA content in the jejunal and ileal mucosa; significantly upre
