Abstract

The current study investigated the effects of two different feeding strategies on the performance and meat quality of squabs (White King pigeon). A total of 108, 21-day-old squabs were randomly divided into three artificial crop milk treatments with different crude protein (CP) levels (14%, 15%, 16%). The parent-fed squab control treatment consisted of 36 pairs of pigeons caring for 2 squabs. Results showed that the 28-day body weight, average body weight gain, index of abdominal fat and breast muscle, muscle shearing force, and fiber cross-sectional area and diameter of squabs in group 1 (16% CP) were the highest. In addition, the low dripping and freezing losses and the minimum malondialdehyde content of muscles in group 1 (16 % CP) were observed. Meanwhile, the activity of glutathione peroxidase in the muscle of the control group was the lowest. The values of redness and yellowness of muscles were higher in the control group than those in the artificial feeding treatments. In conclusion, although the muscle color of artificially fed pigeons is not as good as that of naturally fed ones, the 16% CP artificial diet significantly promoted the growth performance and muscle antioxidant capacity of squabs. Therefore, using 16% CP level of diet for artificially feeding squabs during the late stage of growth is recommended.

不同饲养策略对生长后期鸽雏生产性能和肉品质的影响

本研究研究了两种不同饲养策略对乳鸽生产性能和肉品质的影响。试验选用21日龄的108只乳鸽，随机分为粗蛋白质（CP）水平分别为14%、15%和16%的3种人工作物乳处理。母饲乳鸽对照组为36对鸽，照顾2只乳鸽。结果表明：1组（16% CP）乳鸽28日体重、平均增重、腹脂肪和胸肌指数、肌肉剪切力、纤维截面积和直径均最高；此外，观察到1组（16% CP）肌肉滴损和冷冻损失低，丙二醛含量最低。同时，对照组肌肉中谷胱甘肽过氧化物酶活性最低。对照组肌肉的红、黄度值均高于人工喂养组。由此可见，虽然人工饲养的鸽子肌肉颜色不如自然饲养的鸽子，但16% CP的人工饲粮显著提高了乳鸽的生长性能和肌肉抗氧化能力。因此，建议在生长后期使用16%粗蛋白质水平的饲粮进行人工饲养。
