It does appears that a good blend of organic acids combination in water perform the same functions in poultry health too, or are they different interm of functions?

Egg size, (%) of egg production and eggshell.

Feed composition critically affects both egg quality and production by providing essential nutrients for yolk and shell formation and overall hen health.

Highly Pathogenic Avian Influenza, Newcastle Disease, Infectious Bronchitis and Infectious Bursal Disease are major viral cause of concern in India. In bacterial diseases, coli, clostridia, salmonella can cause problems.

Treatment protocol must be justified by history and preliminary case study. Don’t just start by administering antibiotics. First go with the cause and probable disease and then select drug/electrolyte accordingly.

How much temperature and pressure should be maintained during first drying and second drying in case of animal feed?
-
1️⃣ First Drying (Primary Drying / Pre-Drying)
Objective: Remove bulk moisture without compromising nutrient content.
Temperature: 60–80 °C (140–176 °F) for most feed meals.
Avoid temperatures above 85°C to prevent protein denaturation or vitamin loss.
Pressure: Usually, atmospheric pressure in standard dryers.
In some industrial setups with vacuum dryers, a slight vacuum (~0.8–0.9 atm) may be applied to reduce temperature.
Moisture Target: Reduce from ~50–55% to ~25–30% moisture content (depends on feed type).
Airflow: Moderate airflow to remove vapor without blowing feed particles out.
2️⃣ Second Drying (Final Drying / Conditioning Drying)
Objective: Achieve safe storage moisture (8–12%) and improve shelf life.
Temperature: 70–90 °C (158–194 °F) for grains or feed pellets.
For heat-sensitive ingredients (vitamins, enzymes), keep it lower (~70–75 °C).
Pressure: Usually atmospheric. Vacuum drying can allow a slightly lower temperature.
Moisture Target: Final product ~10–12% moisture.
Airflow: Higher airflow for uniform drying; avoid overheating localized spots.
⚠️ Key Notes:
Overheating can cause nutrient loss, protein denaturation, and pellet cracking.
Pelletized feed: pre-drying at lower temp (~60 °C), then conditioning (steam) before final drying.
Vacuum dryers: lower temp and pressure reduce nutrient damage.

Nice information
-
Low egg production in layers is often linked to poor nutrition, disease outbreaks, stress, or improper management such as inadequate lighting or overcrowding. Regular monitoring of feed quality, health, and housing conditions is essential to sustain high productivity.
-
poor lighting system at day n night
old age.
feed quality to be checked
stress
quality and quantity of water available to birds.
-
Less nutrient provide
-
Stress, poor nutrition, incorrect lighting, the advancing age of hens.
-
Excess Ca lead to eggshell fragile.
