- 动物营养 动物营养
- 兽医医学 兽医医学 兽医医学
背景情况:
- 结核性肠炎 (NE) 在家禽行业造成重大经济损失,在抗微生物生长促进剂 (AGP) 禁令后,发病率增加.
- 传统的NE控制依赖于AGP,但替代品现在对于可持续的肉生产至关重要.
研究的目的:
- 评估Viligen,一种新型料添加剂的疗效,作为Enramycin的替代品,用于控制 brojlers中的亚临床死肠炎.
- 为了比较Viligen和Enramycin对 brojler性能,血液参数,肠道健康和尸体产量的影响.
主要方法:
- 1150只肉被分为五组:负控,正控 (恩拉米辛) 和三个Viligen含量级 (500,1000,1500克/).
- 使用Eimeria spp.诱导了亚临床NE. 和Clostridium perfringens 的挑战.
- 评估的参数包括料转换率 (FCR),血液样本,肠道形态,病变得分和尸体产量.
主要成果:
- 在所有度的Viligen养肉的表现,血液参数和尸体产量与接受Enramycin治疗的群体相似.
- 与阳性对照相比,更高的Viligen含量水平 (V1500) 显著减少了肠道病变.
- 与21天的阳性对照组相比,V500组表现出改善的肠道形态 (较高的小毛病高度:密室深度比率).
结论:
- 维利根有效地减轻肠道损伤,并支持在亚临床死性肠炎的模型中 brojler 的表现.

01:27Microbial Growth Media
Microbial growth media are essential tools in microbiology, providing the nutrients and conditions necessary to cultivate and study microorganisms. These media are categorized by their composition, consistency, and functional roles, enabling researchers to investigate microbial physiology, behavior, and interactions.Types and Consistencies of Growth MediaGrowth media can be solid, liquid, or semisolid. Solid media, often agar-based, allow visible colony growth for isolation and enumeration.
01:29Methods for Controlling Microbial Growth
Microbial growth control refers to various methods employed to inhibit, reduce, or eliminate microorganisms to ensure safety and hygiene across different settings. These methods are categorized based on the target environment and the level of microbial control required.Biocides are versatile agents designed to control microorganisms by either inhibiting their growth or outright killing them. These agents work through various physical, chemical, mechanical, or biological mechanisms. The...
01:28Biological Methods for Microbial Control
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...
