When substituting DORB, monitor diet fiber and rebalance energy, amino acids, and NSP support using the Proease matrix in formulation software.

Hydrolyzed protein is a solution derived from the hydrolysis of a protein into its component amino acids and peptides.

A hydrolyzed protein is composed of short peptide chains and amino acids the body can quickly absorb these nutrients and begin rebuilding cells bigger than before.

Growease contains minimum 20 % hydrolyzed protein which enzymatically processed with high profile amino acids, immunoglobulins and other immunomodulators. It also contains minimum 1% of omega 3 fatty acids.

If birds are underweight and affected from any viral challenges. In both condition we should provide Growease for atleast 15 days @ 1kg per ton of feed.

Other than growth promoting and immune modulating ingredients, Growease also contains antimicrobial agents and digestive enzymes.

High protein sources cannot fulfill the protein requirement of the birds because it will require more energy to digest it, but we must add Growease because of its composition which can enhance synthesis of amino acids in the body for fast weight gain and digestive enzymes for better digestion.

Yes, we can provide details institutional as well farm trial reports of Growease.

Yes. Growease will definitely improve the FCR.

No.

Growease is cost around 0.60 paisa per kg of feed @ dose rate of 1 kg per ton of feed.

Probiotics are live micro-organisms which, when administered in adequate amounts, confer a health benefit on the host.

Probiotics are to decrease dysbiosis, an off-balance gut, and increase eubiosis, a healthy, balanced gut.

Probiotics are beneficial microorganisms. They help to support digestive health by supporting a more diverse population of beneficial bacteria in the digestive tract. Digestive health is especially important for raising a healthy flock. Birds establish gut microflora through the feed they eat and the environment in which they’re raised. The goal of feeding a probiotic is to populate the digestive tract with beneficial bacteria, so pathogens like E. coli, Salmonella, and Clostridium have less room to grow. Feeding probiotics early in life to chicks can help give them a head start to good health.

Various strains of bacteria can be found in probiotics. However, it’s important to choose the right strain of probiotic to receive the intended benefits. When looking for a probiotic for your birds, look for one with Bacillus strain, a very hardy strain of beneficial bacteria which populates rapidly. Other probiotics are often mixtures of bacteria such as Lactobacillus, Bifidobacterium and other unknown strains.

Many strains of Bacillus bacteria exist in nature. Like other feed ingredients – vitamins, minerals and protein – it is important to select the right product for your birds’ needs. The mode of action of probiotics in poultry includes maintaining normal intestinal microflora by competitive exclusion and antagonism resulting in: Altered metabolism by increasing digestive enzyme activity and decreasing bacterial enzyme activity and ammonia production; Improved feed intake and digestion; Neutralised enterotoxins and stimulating the immune system

It means not allowing bad bacteria to grow and take over. If the right probiotic is chosen, the microflora will remain stable while lowering the risk of intestinal pathogens becoming a problem.

Probiotics can be offered to birds of all ages. While they can be fed daily to maintain a healthy digestive system, probiotics can work best during times of stress and after antibiotic treatment. Poultry can undergo stress at different times in their life, including: Hatching; Temperature changes; Transportation; New environment; Feed and water changes. An animal’s immune system is suppressed during times of stress. Their feed and water intake may also decrease at the same time. It is important to help wherever possible to keep them clean, dry and comfortable in addition to keeping them hydrated and providing supportive products, including probiotics.

Yes, definitely we can use Bactozest along with the antibiotics in premix, because in premix the antibiotics are used as a growth promoter under the subnormal dosage. So, there is no harm to probiotics in feed premix.

Total viable count of Bactozest is 10 billion CFU/ gm i.e., (10 X 10^9 CFU/gm).

Other probiotics are blends of different probiotic species but the Bactozest is the blend of only Bacillus species which is sturdy and thermostable as compared to other probiotics species.

Bacillus clausii is used for the prevention and control of diarrhea and gut-related infections across poultry, aquatic species, swine, and pets. It helps stabilize the intestinal microflora and supports healthy digestion.

Short- and long-term beneficial effects of probiotics on the gut are the result of a range of mechanisms, including competitive exclusion and direct antagonism of gut pathogens, stimulation of host mucosal immune mechanisms, and reconstitution and enhancement of intestinal barrier function.

Yes. Bacillus clausii have an antibacterial activity against four pathogenic bacteria (Enteropathogenic Escherichia coli, Salmonella, Staphylococcus aureus and Clostridium perfringens.

No, we cannot use it with the higher antibiotics. It is better to use it after 4–5 hrs. of antibiotic treatment to prevent antibiotic associated diarrhea and also to establish the intestinal microbiota.

The Bacillus clausii spores colonize the gut, compete with harmful bacteria, strengthen the gut barrier, and stimulate the immune response — restoring microbial balance.

Yes. Superclausii inhibits a wide range of gut and water pathogens including Vibrio, E. coli, Salmonella, and Clostridium perfringens.

For prevention, it's best to use it during the first week of life, after antibiotic treatment, or during stress periods. For treatment, it can be given in higher doses for 3–5 days.

Yes. Format-specific dosage schedules are available — whether in feed (FS), water (WS), or oral drops (PI). Our technical team can provide exact protocols.

Yes. Superclausii-WS and PI are effective during early life stages for shrimp, piglets, and puppies to establish healthy gut flora and reduce early-stage diarrhea.

No. Superclausii is safe, non-toxic, and does not cause any residues or resistance issues — even if accidentally overused.

Acidsand is a blend of organic acids like formic, propionic, and benzoic acid that support gut health and digestion without leaving harmful residues. Unlike antibiotics, it doesn’t create resistance and is safe for long-term use.

It lowers gut pH, improves enzyme activity (like pepsin), supports better protein digestion, and inhibits harmful bacteria like E. coli and Clostridium. This improves feed intake, FCR, and bird growth.

In most cases, yes. When used properly, Acidsand helps maintain bird health and performance without the need for AGPs, especially in well-managed flocks.

You can start from day 1. In fact, using it in drinking water for the first 7 days helps chicks establish good gut health early on.

Yes. It reduces undigested protein and harmful microbial activity, which lowers ammonia levels and improves the litter environment.

[Please confirm: Should we recommend daily use or a pulsed schedule?]

Unlike probiotics that introduce new bacteria, Neurogen creates a gut environment that feeds and strengthens the good bacteria already present. This helps birds build long-term resistance and stabilize gut health more effectively.

Feeding beta-glucans daily through Neurogen trains the birds’ immune system from within. It prepares them to fight infections better, especially during stress, weather shifts, or vaccinations.

Yes. Neurogen helps balance gut microflora and improve digestion, which results in firmer droppings, reduced ammonia, and better litter quality — especially helpful in early chick development.

Absolutely. Its immune-boosting and gut-protective action helps chicks and older birds tolerate stress better, lowering the risk of secondary infections and mortality.

Yes. Toxin binders and acidifiers target external threats, while Neurogen builds internal gut strength and immune resilience. Think of it as ‘gut insurance’ — working alongside other solutions, not replacing them.

Yes. Within 7–10 days, you’ll notice improved feed intake, better uniformity in flock size, less digestive distress, and more active birds. In layers, egg quality and HU value also show improvement over time.

Definitely. Antibiotics wipe out both good and bad bacteria. Neurogen helps rebuild the beneficial flora and strengthens gut lining, speeding up recovery and reducing relapse chances.

Yes. It is effective across broilers, layers, and even breeders — just follow the appropriate dosage. It improves FCR in broilers and enhances egg quality and shell strength in layers.

Neurogen combines MOS, FOS, and beta-glucans — all three working together. Many products have only one component. The triple-action blend supports gut health, immune response, and nutrient absorption more comprehensively.

Start from Day 1 for chicks and continue consistently for best gut development. For older birds, begin usage during pre-laying or recovery phases for enhanced performance and resilience.

Phytoease fights harmful bacteria naturally using plant compounds. Unlike antibiotics, it doesn’t create resistance or leave behind residues — making it safer for long-term use and for "No Antibiotics Ever" (NAE) programs.

Yes. Phytoease improves digestion, strengthens immunity, and reduces bacterial load in the gut — all of which help birds grow better, convert feed more efficiently, and stay healthier without antibiotics.

It contains powerful actives like Andrographolides (from Kalmegh), Eugenol (from clove), Withanolides (from Ashwagandha), and Gingerol (from ginger). Each of these supports gut health, immunity, and stress tolerance.

Phytoease is not a medicine, but it does boost the bird’s immune system and antioxidant defense. When used continuously, it helps birds resist and recover from infections more easily, especially during stress.

Yes. Phytoease is designed as a standalone alternative to AGPs. It works by naturally enhancing gut and immune functions, so there's no need for additional growth-promoting antibiotics.

Yes. Phytoease works well with acidifiers, toxin binders, and probiotics. In fact, it complements them — especially when aiming for a fully antibiotic-free nutrition strategy.

Pel Bond is a natural binder added to poultry feed during pelleting. It helps make the pellets harder, more durable, and less dusty, so your birds get the full benefit of every bite.

With Pel Bond, your pellets don’t break easily, stay strong during transport, and reduce wastage in feeders — which means better feed intake and improved bird performance.

Yes. Stronger, more compact pellets mean less crumbling during transport or handling. This reduces dust in poultry feeders and feed loss in water bodies for fish and shrimp.

Absolutely. Pel Bond is made from natural, plant-based starches and gums and is safe for broilers, layers, breeders, as well as freshwater and marine species.

Pel Bond works best in pelleted feed, so it’s mainly used at feed mills. If you’re buying pellet feed, ask your supplier if they’re using a binder like Pel Bond to ensure better pellet quality.

No. In fact, it improves feed flow and uniformity, which supports better feed intake. The animals receive consistent, intact pellets that improve conversion and growth.

Yes. Even if the feed contains dusty or fibrous ingredients, Pel Bond helps bind them properly — giving you good pellet quality with every batch.

Pel Bond is added in very small amounts (1–2 kg per ton) and actually helps reduce losses and improve efficiency, making it a cost-effective investment.

No. Pel Bond has no noticeable effect on feed color, taste, or smell, and your birds will accept it just like regular feed.

You can ask your feed supplier if they’re using a pellet binder like Pel Bond. If not, you can request it or ask to add it while processing your feed.

Yes. That foul smell is caused by anaerobic bacteria producing hydrogen sulfide. Aquaclean breaks down the excess feed and waste, reducing toxic gas buildup and restoring pond bottom health.

It’s not too late. In fact, using Aquaclean around the 3rd or 4th week helps control early sludge buildup and keeps Vibrio and other harmful bacteria from taking over. Earlier use leads to better long-term pond stability.

Yes, in fact, rainy weather is a perfect time to use it. Aquaclean helps stabilize fluctuating pH and reduces nutrient spikes that often lead to plankton crashes or sudden stress in shrimp/fish.

Absolutely. Those bubbles are mostly ammonia or methane trapped in the sludge. Aquaclean breaks down that sludge and reduces gas release, leading to cleaner bottoms and fewer air pockets.

Yes. Uneven phytoplankton and white foam often indicate organic overload or bad bacterial activity. Aquaclean helps restore microbial balance, indirectly promoting a stable, even bloom and reducing surface scum.

Wait at least 48 hours after antibiotic application. Aquaclean works with live bacteria, so give time for the antibiotic residues to fade before introducing beneficial microbes.

Not completely — but regular use can significantly reduce the need for frequent water exchange, especially in closed systems or areas with poor water availability. You’ll notice clearer water and better waste breakdown.

Yes, but for best results, mix Aquaclean in water and apply across the pond, not just near aerators. If aeration is uneven, try applying more near dead zones or areas with poor circulation.

Yes, but dosage and timing may vary. In biofloc, Aquaclean can help control heterotrophic imbalance and improve water stability. Use cautiously based on carbon/nitrogen ratio and floc condition.

Yes, indirectly. Cleaner bottoms and reduced stress improve molting consistency. By reducing ammonia and sludge, Aquaclean lowers molting-related mortality and improves shell quality over time.

Yes. Poor water quality often disrupts gut flora and appetite. Stablegut helps restore the gut microbiome, encouraging feed intake and digestion to bounce back quickly.

Wait 48–72 hours after antibiotics. This ensures residues are cleared so that the live probiotics in Stablegut can colonize effectively.

Yes, indirectly. While it’s not a direct cure, Stablegut helps stabilize gut flora, which is one of the main triggers of white feces, especially under stressful or fluctuating pond conditions.

Stablegut is safe for every meal. For better results, apply in at least one major meal daily, ideally during warmer parts of the day when digestion is active.

Yes. Just make sure not to mix it with acidic or strongly oxidizing substances, as they can reduce probiotic viability. Otherwise, it pairs well with most nutritional supplements.

Most farmers observe noticeable improvements in feed intake and fecal consistency within 7–10 days, and growth/FCR improvements by the third week of regular use.

Yes — they serve different roles. Aquaclean works in the pond environment; Stablegut works inside the animal’s gut. Using both builds a complete health strategy — clean pond + strong gut = better survival and growth.

Absolutely. In fact, gut stress is common during molting. Stablegut supports better feed absorption and reduces stress during this sensitive phase.

Yes. These conditions often trigger gut imbalances and disease. Continued use helps maintain microbial stability and reduces mortality risk during environmental stress.

Yes. Stablegut improves digestive efficiency and final feed conversion, making it useful even in late-stage culture to push final weights and reduce feed cost per kg of biomass.

Aquazest is most effective when used proactively. Start use before expected stress events like water exchange, heavy rains, or disease seasons to build stronger immunity in advance.

Yes. While it doesn't cure viral diseases, Aquazest helps boost the immune response and reduce mortality by strengthening the shrimp’s natural defenses, giving them a better chance of survival.

Yes, Aquazest can safely be used alongside most antibiotics and probiotics. In fact, combining it with gut stabilizers like Stablegut enhances overall recovery and performance.

Farmers often report improved feed intake, firmer gut, stronger activity, and lower early-stage mortality within 7–10 days of regular use — especially under stress.

Yes. Using it 5–7 days before harvest or transportation helps animals cope with stress better, reducing mortality and improving post-harvest quality.

Most premixes contain inorganic selenium, which is less bioavailable. Aquazest contains organic selenium, which is better absorbed and more effective under stress conditions.

Definitely. Early-stage shrimp and fish benefit from stronger immune priming and gut health, which Aquazest supports through beta glucans and MOS.

For preventive use, you can dose every alternate day. During stress or disease, daily top dressing for 7–10 days is recommended for best results.

Yes, it’s effective in both shrimp and fish species. The immune-modulating and antioxidant benefits apply across aquaculture systems.

While not a shell-hardener, Aquazest improves gut health and mineral absorption, which can indirectly support shell development and post-molt recovery.

Aquahatchpro should be introduced from the rotifer culture stage and continued through Artemia enrichment and larval tanks. Early usage ensures good microbial conditioning from the beginning.

Yes, it can be directly applied to larval rearing tanks, rotifer tanks, or during live feed enrichment. It works both in water and via ingestion by larvae.

No. Aquahatchpro does not affect live algae, and its Pediococcus strain is compatible with green water systems, helping reduce Vibrio without harming microalgae.

By improving gut colonization, mineral absorption, and immune modulation, it reduces stress and supports skeletal development, minimizing deformities during sensitive stages.

It’s best to avoid simultaneous antibiotic use, as antibiotics may neutralize probiotics. Instead, use probiotics during recovery or prophylactically, not during antibiotic treatment.

While not a treatment for protozoans, it strengthens gut and immune systems, reducing secondary infections and stress susceptibility, which helps larvae recover faster in multi-challenge scenarios.

No. Aquahatchpro is a complement, not a substitute, for hygiene protocols. Continue your standard disinfection, biosecurity, and water management practices.

For best results, use it daily until the fry are weaned onto formulated feed — usually through the entire larval stage and early nursery phase.

Yes. Aquahatchpro is effective in both marine and brackish hatchery systems, including shrimp, seabass, and tilapia larvae.

Aquahatchpro is safe and non-toxic, even if slightly overdosed. However, for cost-efficiency and optimal results, it’s best to follow the recommended protocol or consult a technician.
