What are the main hazards associated with dust explosions in a feed mill, and how would you implement a prevention and mitigation plan?

[Muhammad Ikram]

What laboratory analyses are essential for incoming raw materials to ensure compliance with purchase contracts and legal standards?

[Muhammad Ikram]

How would you implement a cross-contamination prevention strategy when producing feeds for both ruminants and poultry in the same mill?

[Muhammad Ikram]

Which critical control points must be established under HACCP for batching, mixing, and pelleting?

[Sonter Samuel Akoho]

That may cause unneccessary stress to the flock

[Muhammad Ikram]

How can statistical process control (SPC) be applied to monitor pellet durability, mixing uniformity, and milling particle size?

[Muhammad Ikram]

How do you calculate the economic trade-off between energy use in fine grinding (hammer mill) and potential feed conversion efficiency improvements in animals?

Can we combine fowl pox vaccine with AE vaccine in parent flock

The hatching window is the period from the emergence of the first chick to the last chick in a given hatcher.

In ideal, uniform conditions with modern single-stage incubation, this window is usually kept at 12-24 hours for broilers.

In practice, commercial broiler hatcheries may experience a window of 24 to 48 hours, though a shorter window is preferred to reduce problems like dehydration in chicks that hatch early and must wait for others to finish. This prolonged hatching window results in delayed access of water and feed to chicks.

Reducing variability in hatch time helps ensure the entire group of chicks can be managed more uniformly for health and performance.

Factors Affecting the Hatching Window-

• The precision of incubation parameters such as temperature, humidity, ventilation, and turning influences the spread of hatch times
• Egg characteristics like shell conductance, size, breeder flock age, and egg storage time also play a role but are more pronounced in mixed batches
• Machine design and uniformity of airflow and temperature throughout the hatcher are critical in narrowing the window, with modern single-stage incubators offering better control compared to multistage systems

By closely managing the hatching window, broiler producers can maximize chick uniformity, health, and overall flock performance.

[Dr. Mahmoud]

Massive informations!

[Olamide]

The question is not clear, please be a little more elaborate

[Muddasar]

Exactly, hygiene, litter & biosecurity all work best together.

[Muddasar]

Absolutely right. Keeping litter dry is one of the simplest yet most effective steps.

[Muddasar]

Thanks Victor . Solid points . Isolation along with hygiene makes a big difference.

[Muddasar]

Yes biosecurity & litter management are really the backbone for controlling coccidiosis.
