摘要

本研究评估了日粮中添加混合发酵枇杷叶茶渣(MFL)对津岛-日本杂交鸡肌肉中α-生育酚浓度和滴水损失的影响。尽管茶叶渣中的β-胡萝卜素、α-生育酚和儿茶素总量明显低于绿茶浸泡液,但茶多酚总量明显高于绿茶浸泡液,1,1-二苯基-2-苦基肼自由基清除活性也高于绿茶浸泡液,这表明茶叶渣具有更强的抗氧化性。将 120 只 62 日龄的津岛-日道杂交雄鸡分为两组。对照组饲喂基础日粮(含 16.5% 粗蛋白和 12.77 兆焦/千克代谢能的商业育成日粮),试验组在基础日粮中添加浓度为 1.0% 的 MFL,直至 90 日龄。两组之间的体重、体重增加、采食量和组织质量没有显著差异。膳食中添加 MFL 能显著提高胸肌中的α-生育酚浓度,减少肌肉滴水损失。同时,肌肉的 K 值也降低了,这表明肉的新鲜度提高了。这些结果表明,膳食中添加 MFL 可提高对岛-日本杂交鸡胸肌的保质期和持水能力。

Effect of a Mixed Fermented Loquat Leaf Tea By-Product on the Growth Performance and Meat Quality of Tsushima-Jidori Crossbred Chicken.

In the present study, the effects of dietary supplementation with a mixed fermented loquat leaf tea residue (MFL) were evaluated on muscle α-tocopherol concentration and drip loss of Tsushima-Jidori crossbred chicken. MFL contained significantly less β-carotene, α-tocopherol, and total catechin than that of residues of green tea leaf infusion, although total polyphenol was significantly higher and 1,1-diphenyl-2-picrylhydrazyl radical-scavenging activity tended to be higher, indicating increased antioxidant properties. A total of 120 male Tsushima-Jidori crossbred chickens were divided into two groups at 62 days of age. The control group was fed a basal diet (commercial finisher diet containing 16.5% crude protein and 12.77 MJ/kg metabolizable energy) and the test group was fed a basal diet supplemented with MFL at a concentration of 1.0% until 90 days of age. Body mass, body mass gain, feed intake, and tissue mass did not significantly differ between the two groups. Dietary supplementation with MFL significantly increased breast muscle α-tocopherol concentration and reduced muscle drip loss. This was accompanied by a lower muscle K-value, which indicated the freshness of the meat. These results suggested that dietary supplementation with MFL improved the shelf life and water-holding capacity of breast muscles of Tsushima-Jidori crossbred chickens.
