概括
牛乳替代剂或补充剂并没有改善通过剖腹产产产生的牛肉小牛的血清IgG. 母乳母乳的天然哺乳导致IgG水平更高,突出显示了母乳母乳对被动免疫转移的重要性.
科学领域:
- 兽医医学 兽医医学 兽医医学
- 动物科学动物科学
- 新生儿小牛护理 新生儿小牛护理
背景情况:
- 牛犊的剖腹产 (C-sections) 增加了被动免疫转移 (FTPI) 失败的风险.
- FTPI与预先断奶的牛肉小牛的发病率和死亡率较高有关.
- 对于剖腹产小牛,缺乏具体的乳酪指南.
研究的目的:
- 为了评估乳酪替代剂或补充剂是否会增加剖腹产牛犊的血清IgG.
- 为了比较接收乳母乳产品的剖腹产小牛的IgG水平与自然哺乳的小牛的IgG水平.
主要方法:
- 32只肉牛和小牛接受了可选的剖腹产.
- 牛犊被分为三个组:仅用乳母补充剂,乳母补充剂然后哺乳,以及仅用天然哺乳剂.
- 血清IgG度是在生命48小时后测量的.
主要成果:
- 48小时后血清IgG水平在自然哺乳的小牛 (C组) 中高于仅接受乳母替代剂的小牛.
- 产于多头母牛的小牛血清IgG水平较高.
- 与自然哺乳相比,乳酪替代剂或补充剂没有产生较高的血清IgG度.
结论:
- 牛乳替代剂和补充剂都没有有效地增加由可选剖腹产产产生的牛肉小牛的血清IgG.
- 母乳母乳的自然哺乳对于剖腹产小牛的充足的被动免疫是至关重要的.
- 可能需要进一步的研究来优化剖腹产小牛的被动免疫策略.

2.7K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

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.
