摘要

本研究旨在探討飼糧中添加香椿粉對肉鵝生長、免疫及屠體品質之影響。試驗使用8週齡肉鵝24隻，逢機分配至對照組及額外添加1%香椿粉組，以欄為單位，每欄4隻，公母各半，3重複。試驗期間，鵝隻每2週秤重1次，每4週採血1次，於16週齡進行肉鵝屠宰並分析胸肉品質。結果顯示，添加香椿粉對肉鵝生長、血液生化值及胸肉之pH、L、a、b值皆無顯著影響，惟顯著提升16週齡肉鵝血清G型免疫球蛋白濃度及胸肉多元不飽和脂肪酸比例，且感官品評亦有較佳之風味、嫩度及總可接受性（P＜0.05）。綜上所述，飼糧中添加香椿粉對肉鵝生長雖無顯著改善效果，惟可提升其免疫力且使其肉質有較佳風味，可供特色化鵝隻生產使用。

The aim of the current study was to investigate the effects of Toona sinensis powder supplemented to diets on growth and immunity and carcass quality of breast meat in geese. A total of twenty-four geese were randomly divided into the control and the treatment groups comprising 2 males and 2 females at 8 weeks of age per pen (3 replicates). Body weight and blood samples were collected at 2 and 4 weeks of age. Then, the carcass characteristics and breast meat quality of hybrid geese were collected at sixteen weeks of age. The results showed that there was no significant differences between the control and treatment groups in terms of growth performances, the values of blood biochemical parameters and pH, L, a, and b of breast meat quality. Notwithstanding that there were significantly higher concentration of IgG in serum, the content of polyunsaturated fatty acid in breast meat and the better flavor, tenderness and acceptability of sensory evaluation in the treatment supplemented with Toona sinensis powder (P ＜ 0.05). In summary, the Toona sinensis powder supplemented to diets did not ameliorate the growth performances in geese. However, for the production of specialized goose industry, Toona sinensis powder could improve immunity and enhance the flavor of geese.
