概括
两个疫苗接种计划显著影响了 brojler的生长和器官比例,但没有对传染性支气管炎病毒 (IBV) 或禽类甲型肺炎病毒 (aMPV) 的免疫反应产生显著影响. 同接种疫苗对抗体标位没有任何不良影响.
科学领域:
- 兽医免疫学 兽医免疫学
- 禽畜科学是一门学科.
- 控制鸟类疾病的控制方法
背景情况:
- 传染性支气管炎病毒 (IBV) 和禽类甲型肺炎病毒 (aMPV) 是家禽的重要呼吸道病原体.
- 有效的疫苗接种策略对于减轻肉生产中的经济损失至关重要.
- 了解疫苗接种计划对表现和免疫反应的影响对于优化家禽健康至关重要.
研究的目的:
- 评估两种不同的针对IBV和aMPV的疫苗接种计划的影响.
- 评估对肉幽默性免疫反应,生产性能和尸体特征的影响.
- 为了确定对所选内部器官百分比的影响.
主要方法:
- 肉被分配到两个实验性疫苗接种组.
- 在多个时间点收集血清样本进行血清ELISA测试 (GMT).
- 分析了生产参数 (体重,料消耗,死亡率) 和尸体组成.
主要成果:
- 疫苗接种计划在整个养殖期间显著影响了体重增加 (P<0.05).
- 在尸体重量中的翅膀,心脏,肝脏和脏的百分比中观察到显著的差异.
- 疫苗接种计划对抗IBV血清反应没有显著影响.
结论:
- 疫苗接种计划影响肉的生长和尸体组成,特别是翅膀的百分比和器官重量.
- 对IBV和aMPV的联合接种疫苗没有对抗aMPV血清反应产生负面影响.
- 该研究强调了疫苗接种时间和成分对 brojiler性能的重要性,而免疫反应需要进一步调查.

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
