不同蛋白原料对豁眼鹅肉品质的影响

Effects of three kinds of protein feed on meat quality of Huoyan geese

选取300只健康、活泼的8周龄豁眼鹅(公母各半),平均体重2 265.75(±268.55)g,采用完全驱组试验设计,将试验鹅随机分为3组,每组设4个重复,每个重复25只鹅,进行为期2周的饲养试验。在保证肥育鹅正常生长所需代谢能、粗蛋白质、钙、有效磷、赖氨酸、蛋氨酸和苏氨酸水平条件下,分别在基础日粮中添加3.0%血粉、3.0%膨化血粉、3.0%鱼粉,研究不同蛋白源饲料对育肥鹅肉品质的影响。结果表明,各组试验鹅肌肉中的干物质、粗蛋白质、粗脂肪等含量均有所提高,其中3%鱼粉组最为显著(P<0.05),除粗蛋白外,3%膨化血粉组与3%鱼粉组间无显著性差异。与3%鱼粉组相比,3%血粉组和3%膨化血粉组肌肉组织的天门冬氨酸、苏氨酸、谷氨酸等的含量均显著性降低,且3.0%膨化血粉组比3.0%血粉组降低的幅度小。在本试验条件下,3.0%膨化血粉完全可以代替相同水平的鱼粉,而对豁眼育肥鹅的肉品质指标无显著性影响。

The paper was aimed to investigate the effect of different proteins material production on meat quality of growing-finishing goose,a total of 300 geese.（sex balance,8 weeks of age,average weight 2 265.75±268.55g）were allotted to 3 groups,each group had 4 replicates with 25 geese in each replicate,the feeding experiment lasted for 14 days.Based on basal diet,3.0% blood meal,3% expanded blood meal and 3% fish meal were added respectively.The results showed that dry matter,crude protein,crude fat content of muslce were increased in 3% blood meal,3% expanded blood meal and 3% fish meal groups respectviely（P0.05）.Compared with 3% fish meal group,aspartic acid,threonine,glutamic acid,etc.in muslce of 3% blood meal group and 3% expanded blood meal group were significantly lower.In this experimental conditions,3.0% expanded blood meal can substitute the same level of fish meal,while fattening geese meat quality traits had no significant difference.
