摘要:

目的 本试验旨在研究翻飞鸽在运动前后血气指标的变化以及血浆差异代谢物,分析其血液中酸碱平衡及其机体代谢差异,为探究翻飞鸽的运动及其疲劳恢复机制提供数据支持。 方法 试验选取180日龄健康状况良好的翻飞鸽12只,公母各半。采集翻飞鸽运动前静息及运动力竭后状态的血液样品,用于血气指标及非靶向代谢组学分析,筛选翻飞鸽运动前后差异代谢物并进行代谢通路分析。 结果 血气指标检测结果显示,与运动前相比,翻飞鸽在运动后血液中二氧化碳分压(PvCO2)和总二氧化碳(TCO2)水平显著降低(P<0.05),红细胞压积(Hct)和血红蛋白(Hb)浓度极显著降低(P<0.01),碳酸氢根(HCO3)、钠离子(Na)等指标均无差异显著(P>0.05)。血浆代谢组学检测发现,与运动前相比,翻飞鸽运动后正负离子模式下分别筛选出差异代谢物,其中别嘌呤醇核糖苷、鞘磷脂、反式-乌头酸、溶血磷酸酯、马钱苷元、琥珀酰腺苷等代谢物显著高于运动前(P<0.05);甘胺酰-亮氨酸、氨基己酸、紫花前胡醇、十七烷酸、棕榈油酸等代谢物显著低于运动前(P<0.05)。差异代谢物显著富集到苯丙氨酸代谢、不饱和脂肪酸生物合成、亚油酸代谢、脂肪酸生物合成等途径。 结论 在本试验条件下,与运动前相比,翻飞鸽运动后血浆中PvCO2、TCO2浓度显著降低;Hct、Hb浓度极显著降低,并且主要影响翻飞鸽糖代谢、脂代谢及氨基酸代谢,试验结果为翻飞鸽运动后恢复及选育提供理论依据。

Abstract:

Objective The trial aimed to investigate the changes in blood gas indices and plasma differential metabolites in tumbler pigeons before and after exercise, analyze their blood acid-base balance and metabolic differences, and provide data support for exploring the exercise and fatigue recovery mechanisms of this breed. Method Twelve healthy 180-day-old tumbler pigeons (6 males and 6 females) were selected. Blood samples were collected in a resting state before exercise and after exhaustive exercise for blood gas analysis and non-targeted metabolomics analysis. Differential metabolites before and after exercise in the pigeons were screened, and metabolic pathway analysis was conducted. Result Blood gas analysis revealed that, compared to pre-exercise levels, the partial pressure of carbon dioxide in blood (PvCO₂) and total carbon dioxide (TCO₂) levels were significantly decreased after exercise (P < 0.05), while the hematocrit (Hct) and hemoglobin (Hb) concentration were extremely significantly decreased (P<0.01). No significant differences were observed in bicarbonate (HCO3) and sodium ion (Na+) levels (P>0.05).Plasma metabolomics analysis identified differential metabolites in both positive and negative ion modes following exercise compared to pre-exercise levels. The levels of the metabolites allopurinol riboside, sphingomyelin, trans-aconitic acid, lysophosphatidic acid, loganetin and succinyladenosine were significantly higher than before exercise (P<0.05). Conversely, the levels of the metabolites glycyl-leucine, aminohexanoic acid, decursinol, heptadecanoic acid, and palmitoleic acid were significantly lower than before exercise (P<0.05). Differential metabolites were significantly enriched in pathways including phenylalanine metabolism, biosynthesis of unsaturated fatty acid, linoleic acid metabolism, and fatty acid biosynthesis. Conclusion Under the conditions of this experiment, compared to pre-exercise levels,the concentrations of PvCO2 and TCO2 in the blood of tumbler pigeons were significantly decreased after exercise, the concentrations of Hct and Hb were extremely significantly decreased. Moreover, exercise mainly affected the glucose metabolism, lipid metabolism, and amino acid metabolism of tumbler pigeons. The experimental results provided a theoretical basis for the post-exercise recovery and breeding selection of tumbler pigeons.
