【摘要】 为了解饲料成分与马岗鹅肉质的关系,用能量和蛋白质基本相同,纤维水平不同的日粮饲喂马岗鹅,探讨不同日粮纤维水平对马岗鹅肉质的影响。结果表明:日粮纤维水平在4.08%～11.90%,对胸肌化学成分、胸腿肌肉的嫩度与系水力、腿肌纤维直径与pH值无显著影响,对腿肌纤维密度和胸肌pH值影响显著。日粮纤维水平为7.97%时,肌纤维直径小、密度大、嫩度好,有利于提高马岗鹅肌肉的品质。更多还原

【Abstract】 In order to understand the relationship between feed composition and meat quality of Magang goose and investigate the effects of different dietary fiber levels on their muscle quality,the Magang geese were fed with different amount of dietary fiber and equivalent amount of protein and energy.The results showed that dietary fiber levels of 4.08%~11.90% had no significant effects on the chemical composition of pectoral muscle,tenderness and water holding of pectoral and leg muscle,fiber diameter and pH value of leg muscle.However,they had significant effects on leg muscle fiber density and pH value of pectoral muscle.Meanwhile,7.97% dietary fiber level was beneficial to improve muscle quality with small muscle fiber diameter,big density and good tenderness.更多还原
