概括
益生菌改善了羊羔的生长和料效率,在0.15%的补充剂中获得最佳结果. 益生菌也提高了表现,尽管效果不如益生菌. 这两种添加剂对于反动物的营养有价值.
科学领域:
- 动物科学动物科学
- 营养科学 营养科学
- 微生物学 微生物学
背景情况:
- 像益生菌和益生菌这样的料添加剂支持肠道健康和动物生长.
- 优化肠道微生物群对于提高动物生产率至关重要.
研究的目的:
- 评估不同水平的益生菌 (曼寡糖化物+β-葡萄糖) 和益生菌 (Bacillus amyloliquefaciens) 补充剂对成长中的羔羊的影响.
- 评估对生长性能,料效率,营养素消化能力和经济可行性的影响.
主要方法:
- 三十只成长中的羔羊被分为五组,接受控制料,或控制料与三种水平的益生菌 (0.50,1.00,1.50克/公斤CFM),或一个水平的益生菌 (1.0克/公斤CFM).
- 进行了150天的食试验,随后进行了消化试验.
- 测量的主要参数包括平均每日增益,料效率,营养物质消化能力和经济效率.
主要成果:
- 与对照组相比,高达0.15%的益生菌补充剂显著提高了平均每日增益和料效率.
- 益生菌补充剂也改善了日常收益和料效率的控制,但不如益生菌.
- 0.10%的益生菌组显示出最高的经济料效率,而益生菌治疗改善了营养消化能力.
结论:
- 益生菌,特别是0.10-0.15%的补充剂,有效地改善成长,料效率和营养利用在成长中的羔羊.
- 虽然益生菌也有利于表现,但在这项研究中,益生菌显示出优异的结果.
- 在反动物中对益生菌,益生菌和共生菌进行进一步的研究是有必要的.

Cloning of Dolly the Sheep
3.8K
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...

Biological Methods for Microbial Control
42
Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
