用酵母 (SY) 补充哺乳驴,改善了牛奶产量和抗氧化剂状况. 确定最佳的SY剂量为0.3 mg/kg,以提高哺乳性能和免疫反应.
科学领域:
- 动物营养和新陈代谢
- 乳制品科学 乳制品科学
- 动物免疫学 动物免疫学
背景情况:
- 驴奶是一种有价值的传统食品,具有生物活动.
- 哺乳驴的低牛奶产量因氧化应激而加剧.
- 补充剂正在探索以减轻这些问题.
研究的目的:
- 为了研究酵母 (SY) 对驴子的哺乳性能的影响.
- 评估SY对抗氧化剂状态和免疫反应的影响.
- 为了确定乳母驴SY的最佳饮食水平.
主要方法:
- 28只正在哺乳的德州驴被分成四组.
- 组接受了补充SY的0,0.15,0.3或0.5 mgSe/kg干物质的饮食.
- 分析了哺乳性能,牛奶成分,抗氧化酶活动和免疫标记物.
主要成果:
- 根据剂量,SY补充剂增加了牛奶产量,牛奶成分产量和牛奶生产效率.
- 谷氨过氧化酶 (GSH-Px),酶 (CAT) 和总抗氧化能力 (T-AOC) 的活性升高.
- 氧化应激标记物 (MDA,ROS,NO) 和促炎性细胞因子 (IL-1β,IL-6,IFN-γ) 减少,而免疫细胞 (WBC,LYM) 和IL-10增加.
结论:
- 饮食酵母补充剂可以提高哺乳期的乳房性能,抗氧化剂状态和哺乳驴的免疫反应.
- 对于哺乳驴,推的SY最佳剂量是0.3 mg/kg.
- SY显示出作为料添加剂的潜力,可以提高奶驴的生产力和健康.

Development of Immunocompetence
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.
