Summary
Phytogenic feed additives show varied results in poultry production. Further research is needed to optimize their use and understand their mechanisms for improved gut health and bird welfare.
Area of Science:
- Animal Science
- Nutritional Science
- Agricultural Science
Background:
- Phytogenic feed additives (PFAs) are plant-derived compounds used in poultry production.
- They contain bioactive ingredients from herbs, spices, and fruits.
- Their impact on poultry health, welfare, and production efficiency is under investigation.
Purpose of the Study:
- To review current trends in PFA use in poultry.
- To focus on PFAs' interaction with the gut ecosystem and function.
- To examine effects on oxidative status, immune system, and synergy with other additives like organic acids.
Main Methods:
- Comprehensive literature review of published documents on PFAs in poultry.
- Analysis of studies investigating PFA effects on gastrointestinal health.
- Evaluation of research on PFA interactions with the gut microbiome and immune responses.
Main Results:
- Published results on PFA effectiveness in poultry are often contradictory.
- More research is required to establish optimal inclusion levels.
- Understanding the mode of action of PFAs is crucial for consistent outcomes.
Conclusions:
- PFAs offer potential benefits for poultry, but their application requires further refinement.
- Elucidating PFAs' interactions with the gut and immune system is key.
- Optimizing PFA use can enhance poultry production, food safety, and environmental sustainability.

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

Body:Bioavailability is a critical pharmacological concept that measures the extent and rate at which an active drug ingredient or therapeutic moiety enters the systemic circulation, remaining unchanged. It's a pivotal factor in determining a drug's efficacy and safety.The Biopharmaceutics Classification System (BCS) plays an essential role in drug development by categorizing drugs into four classes based on their solubility and permeability. This classification aids in understanding drug...

02:35Key Elements for Plant Nutrition
22.4K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
