概括
在山羊中补充绿色微藻并没有改善卵细胞质量,但增强了胚胎发育和线粒体功能. 每天服用20g的Chlorella pyrenoidosa (CH) 对山羊的胚胎质量产生了积极的影响.
科学领域:
- 动物科学动物科学
- 生殖生物学 生殖生物学
- 营养科学 营养科学
背景情况:
- 绿色微藻,如Chlorella pyrenoidosa (CH),因其营养益处而受到探索.
- 研究微藻作为牲畜繁殖补充剂是一个越来越感兴趣的领域.
研究的目的:
- 评估Chlorella pyrenoidosa (CH) 作为营养补充剂的疗效,以改善山羊的卵细胞和胚胎生产.
- 评估CH补充剂对成年雌山羊生殖参数和代谢指标的影响.
主要方法:
- 在成年山羊身上进行了两项实验:体外卵细胞采集 (EVO) 和体内胚胎生产 (IVD).
- 羊被分为对照组和Chlorella组,接受基本饮食或补充CH的基本饮食 (EVO每天10g,IVD每天20g).
- 评估的参数包括卵细胞/胚胎质量,卵泡大小,代谢标志物 (甘油三,胆固醇,葡萄糖) 和抗氧化剂水平 (氨酸过氧化酶).
主要成果:
- 在山羊中,CH补充导致减少食物摄入量和增加脂肪沉积,甘油三,胆固醇和血葡萄糖.
- 虽然卵细胞质量没有受到影响,但CH补充剂增加了卵泡大小和卵泡内甘油三,葡萄糖和谷氨过氧化酶.
- 在体内胚胎生产显示了CH组中更高比例的可移植胚胎,通过MitoTracker和H2DCFDA光指示线粒体活性增强.
结论:
- 在经过测试的条件下,甲 (CH) 补充剂并没有改善山羊中提取的卵细胞的质量.
- 每日20gCH的剂量对体内产生的山羊胚胎的质量产生了积极的影响,刺激了它们的线粒体功能.
- 需要进一步的研究来优化CH的剂量,并了解其在牲畜繁殖中的代谢影响.

Cloning of Dolly the Sheep
3.9K
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

Green Algae

Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
