Main sections of a feed mill

Raw material receiving and storage: This is where raw materials, such as grains and other ingredients, are received, unloaded, and stored in bins or silos.

Grinding and batching: Ingredients are ground to a specific size, often using a hammer mill, and weighed before being sent to the mixer.

Mixing: The ground and batched ingredients are thoroughly mixed with other components, like vitamins and minerals, to ensure a uniform final product.

Pelleting: The mixed feed is compressed and formed into pellets using a pellet mill.

Cooling: Pellets are cooled with air to reduce their temperature, which makes them harder and easier to handle.

Packaging: The final feed is weighed and packed into bags for storage and sale.

7. Delivery Systems: Phage stability (sensitivity to heat, water, or stomach acid) is a major delivery challenge. What are the most promising avenues for developing durable, cost-effective delivery systems (e.g., microencapsulation, specialized feed matrices) that ensure a viable phage reaches the target bacteria in the animal’s gut.

How can the PDCA (Plan-Do-Check-Act) cycle be applied in a laboratory setting within the feed manufacturing industry to ensure accurate testing, consistent results, and continuous improvement in product quality? What are some specific challenges laboratory teams might face in each phase of the cycle, and how can they address them effectively?

Vibration analysis, thermal imaging, and oil analysis are some of the most effective predictive maintenance technologies for reducing unexpected downtime in pellet mills and mixers.

1- What is the ideal DO level in the pond?

The ideal DO level should be maintained above 5.0 mg/L (parts per million).

2- Why does DO level fluctuate during the day?

It fluctuates because phytoplankton, along with the cultured organisms, produce oxygen during the day (photosynthesis) but consume it at night (respiration).

3- What are the main causes of low DO?

The main causes are high biomass respiration at night, overfeeding, and the decomposition of a sudden algal crash.

4- What are the symptoms of low DO in ponds?

Fish and shrimp exhibit lethargy, reduced feeding, and gather at the surface (gasping) or near aerators.

5- How can DO be improved or maintained?

DO is primarily improved by running mechanical aerators to transfer oxygen from the air into the water.

6- What is the best aeration strategy?

The best strategy is to run aerators continuously from sunset to sunrise and strategically during the day for circulation.

7- When is DO most critical in the ponds?

DO is most critical in the early morning (just before sunrise) when it reaches its lowest point.

8- What is / are right timing/s of checking DO in the pond?

The most crucial timing is just before sunrise (to check the minimum level) and again in the mid-afternoon (to check the maximum level).

9- Does pro-biotic has any role in DO management in the pond?

Yes, probiotics help indirectly by reducing organic matter (sludge), which lowers the oxygen consumed by decomposition.

use of vitamins especially vit E and selenium combination after vaccination,

comfortable temperature and ventilation,

don’t use antibiotics till 24 hours before and after vaccination ,

no other change in the flock like shifting, change of litter for 24 hour minimum to reduce stress

thanks very much

At the end of every medications, flushing is highly recommended, hydrogen peroxide ie hydroxycare can be used too,

As part of preparation to receive new stock, hydroxycare is a must, this can equally be followed by isochlor or chlorine to further clean the line after hydrocare ie hydrogen peroxide preparation
