The attached article may add valuable insight to this discussion, emphasizing two key points worth considering:
1. Recent research suggests that the beneficial effects of antimicrobial growth promoters (AGPs) in livestock might result more from their anti-inflammatory properties than their traditional antibacterial actions. This shifts our understanding of how AGPs support animal health and growth, and how feed additives can help reduce gut inflammation.
2. The article also reinforces that biosecurity remains the foundation for preventing disease introduction and spread on farms. Effective biosecurity practices reduce reliance on antimicrobials by minimizing disease risks in the first place.

Let’s say there is no network glitch, some courses have various requirements that must be meet before one is awarded the points. For example:
– Download material
– Attend LIVE Zoom meetings
– Watch Recordings
– Read Presentation slides etc
Just ensure you meet them and keep moving.

Thanks

Is there any reason why it affects only males broilers?

As the Poultry industry moves increasingly toward ‘antibiotic-free’ poultry to address antimicrobial resistance (AMR), how can we effectively emphasize the critical role of vaccines—especially considering that many viral diseases lack effective treatments?

Good question

PROCESSING OF SOYBEANS TO REDUCE ANTINUTRITIONAL FACTORS
The following should be considered as general information only, you should always seek professional advice, specific to your individual circumstances:
Roasting, toasting, boiling, extrusion, autoclaving, and microwave heating are common thermal methods to reduce antinutritional factors. Boiling is more common in human foods and beverages than in feed production.
Protease Inhibitors – heat denatures protease inhibitors like Kunitz trypsin inhibitor (KTI) and Bowman-Birk inhibitor (BBI), significantly reducing their activity. Effective inactivation typically requires temperatures near or above 100°C for sufficient time (e.g., 20–30 minutes).
Complete elimination of residual BBI activity remains challenging. BBI is more heat-stable and hydrophilic, is inactivated more slowly. Heat treatment causes cleavage of specific peptide bonds in BBI, reducing its inhibitory activity against trypsin and chymotrypsin, although residual activity can remain if heating is insufficient.
Lectins – also known as soy hemagglutinins, are largely inactivated by aqueous heat treatments near 95–100°C, especially when soybeans are fully hydrated by soaking before heating. Typical treatments like boiling for 10 minutes or autoclaving effectively abolish lectin activity.
Tannins And Phytic Acid – boiling for about 60 minutes is very effective in eliminating tannins and reducing phytic acids in soybeans. Roasting and microwaving also reduce these compounds but to a lesser extent than boiling.
Saponins – roasting at temperatures between 120–140°C for about 5-9 minutes can reduce saponins, though this method is less effective than steaming or boiling in moisture-rich environments.
Excessive heat or very long heating times can damage essential amino acids, particularly lysine and reduce overall protein quality (Maillard reactions), so optimal duration-temperature combinations should be used to maximize inactivation of antinutritional factors while while avoiding nutritional losses.
Fermentation of soybeans is a highly effective method to significantly reduce or transform antinutritional factors into more bioavailable forms. Due to their high cost, fermented soybeans are usually only used in poultry starter feeds.

Absolutely! In laying birds, deficiency can cause osteoporosis and poor egg shell quality, even with sufficient calcium and phosphorus in the diet. A key vitamin indeed.

SDS is a common experience with farming broilers. Mortality happens within the twinkle of an eye with no prior warnings or symptoms. Thanks for the write up

Yes, I agree @FARUQ
-
Well detailed
-
Monitor ambient humidity and temperature, adjust airflow based on feed moisture content, and maintain cooler cleanliness.
-
Focus on optimizing raw materials, pre-grinding, hammer mill parameters, and maintenance.
