概括

将动物技术添加剂与抗生素增长促进剂 (AGPs) 结合起来,改善了 brojler 的性能和免疫功能. 精油在提高肉生长和健康方面显示出最有希望的结果.

科学领域:

动物科学动物科学
禽类营养养禽类营养
免疫学免疫学免疫学

背景情况:

抗生素增长促进剂 (AGPs) 在 brojiler生产中被广泛使用,但面临越来越多的审查.
动物技术添加剂为改善动物健康和表现提供了AGP的潜在替代品或补充剂.

研究的目的:

评估畜牧技术添加剂与AGP结合对 brojler的表现产生的协同效应.
评估对免疫参数,肠道形态和整体生产力的影响.

主要方法:

1400只Cobb 500只雄性肉小被分配给七种饮食治疗,包括单独使用AGP,使用各种动物技术添加剂 (益生菌,益生菌,精油,有机酸) 的AGP和对照.
评估的参数包括体重增加,料摄入量,料转换率,生产效率指数,白细胞差异活性,细胞活性,肠道组织形态测量和内部指数.

主要成果:

结合AGP和畜牧技术添加剂的处理显著改善了体重增加,料摄入量,料转换率和生产效率指数 (p < 0.05).
在没有AGP的鸟类或有AGP但没有添加剂的鸟类中,食细胞活性降低.
与对照组相比,与动物技术添加剂配合AGP的鸟类表现出较差的肠道组织形态测量和较低的内部指数.

结论:

当与AGPs一起使用时,动物技术添加剂可以有效地提高肉的性能和免疫功能.
精油在测试添加剂中表现出最显著的积极影响,这表明它们在 brojiler料配方中的潜力.

Microorganisms in Medicine and Therapeutics

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Antimicrobial Effectiveness

Antimicrobial Effectiveness

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...
