These questions are very good and those answering them need to make sure they are answering correctly – hopper size for main ingredients depends on each individual feed mill, the type of major ingredients used and the maximum total weight of major ingredients in a batch – please remember that density of major ingredients has a role in the volume they will take in the hopper – light fluffy materials such as soybean hulls, rice hulls, wheat bran take up more space and may create a situation where the hopper volume is full but target weight has not been achieved. The discharge angle and size of opening are important as they control how quickly and completely the scale discharges into the mixer. If used the design of minor ingredient scales follows that of major scales. Micro ingredient system scales are a special case and vary with manufacturer – if micro ingredients are weighed manually a ‘bench-top’ scale will work and then the total is added to the mixer after all other dry ingredients have been discharged.

There is a recording of Dr. Adam Fahrenholz discussion of “batching and mixing” and a PDF. This is an excellent place to find information.

As I explained to the groups my contract concludes on September 30 – I do not know if I will continue to have access to the discussion boards, but if I am able I will continue to follow.

Weighing hopper should be at last of 1.5 ton capacity so that the weigh can be more or less hence the weighnig hopper shoud be of good quality too which make sure the quality.

The type of housing constructed for birds depends on several factors like bird species, climate, production goals, and biosecurity needs. Here are the main types explained in plain terms:

• Deep litter housing: Birds live on a floor covered with bedding material like rice husk or sawdust. It’s simple, cost-effective, and common in small to medium operations.

• Slatted floor housing: The floor is raised and made of slats, allowing droppings to fall through. This improves hygiene and is often used for breeders or larger flocks.

• Environmentally controlled (EC) housing: These are modern, enclosed structures with automated systems for temperature, humidity, and ventilation. Ideal for high-density, commercial operations where performance and disease control are critical.

• Free-range or open-sided housing: Birds have access to outdoor areas. This suits organic or welfare-focused farms and works well in moderate climates.

• Battery cages: Used mainly for layers in commercial egg production. Birds are housed in individual cages arranged in tiers, allowing for efficient feeding and egg collection—but with limited mobility.

Let’s dive into the world of prebiotics and probiotics in aquaculture, particularly in shrimp and fish farming. Prebiotics are non-digestible fibers or compounds that serve as food for beneficial microorganisms in the gut, promoting their growth and activity. They can be added to feed or applied directly to the water to enhance the growth of beneficial microbes. Probiotics, on the other hand, are live, beneficial microorganisms that confer health benefits to the host when administered in adequate amounts. They can be used to improve the health and well-being of shrimp and fish by modulating their gut microbiota.

Prebiotics and probiotics have distinct functions, with prebiotics stimulating the growth of beneficial microorganisms in the gut and probiotics introducing live, beneficial microorganisms into the gut. Both can enhance immune system function, improve nutrient absorption and utilization, reduce stress and disease susceptibility, and promote overall health and well-being.

The effectiveness of prebiotics and probiotics in culture ponds is influenced by several factors, including water quality, diet and nutrition, microbial community, and dosage and duration of application. Poor water quality can stress the animals and reduce the effectiveness of prebiotics and probiotics, while a balanced diet that includes prebiotics or probiotics can enhance their effectiveness.

Probiotics can have a positive impact on water quality management in aquaculture by reducing waste, improving water clarity, and enhancing beneficial microbial communities. They can help break down organic matter, control the growth of harmful microorganisms, and promote a healthy ecosystem.

Some potential additional questions to explore include how prebiotics and probiotics can be used in combination to enhance their effectiveness, the specific benefits of using prebiotics and probiotics in different stages of shrimp and fish development, and how farmers can monitor the effectiveness of prebiotics and probiotics in their aquaculture operations. By understanding the benefits and applications of prebiotics and probiotics, farmers can make informed decisions to improve the health and productivity of their aquaculture operations.Let’s dive into the world of prebiotics and probiotics in aquaculture, particularly in shrimp and fish farming.
