IONIC ADSORBING POWER OF NUFEED

 

During the thermal alteration period amorphous material was washed from the clays leaving a 2D skeleton of aluminum and silica oxides, which, due to a unique configuration, have a high negative charge (cation exchange capacity; typically > 100 meq/ 100gm). Positively charged cations in solutions (or molecules suspended in air) can be absorbed into the zeolite and, depending on cation concentration, charge characteristics and pH, can later be released.

 

The 3D skeleton has a large internal surface area (145m2/ gm) with pore sizes in the lattice work that allow some molecules to enter and be trapped, whilst other are excluded. Geologically young zeolites like NuFeed®tend to have less blockages in the lattice work and are therefore better able to absorb more liquids than older, more glassy zeolites. A large internal volume enables these younger zeolites to adsorb up to 100% of their own weight as water/ liquid.

 

MYCOTOXIN ADSORPTION BY NUFEED

 

Studies performed to measure the mycotoxin adsorption capability of NuFeed® when added to animal feeds. NuFeed® was shown to bind toxin’s, ammonia, and other gases, aid pelleting and feed flow ability and improve mineral utilization.

Due to their unique structure of New Zealand’s “young” zeolite, NuFeed® naturally absorbs a number of mycotoxins in feed. Independent New Zealand studies have measured the adsorption capacity of NuFeed®

 

Experiment 1

 

The first study involved an in vitro absorption assay measuring the effect of NuFeed®added at either 1% or 2.5% to an artificial gastric juice containing either 0.5g/ mL or 2g/ mL of ochratoxin A. This toxin occurs throughout the world and has shown medium binding to some commercial aluminosilicate feed additives. Results of this experiment showed that addition of 1% NuFeed® reduced the free ochratoxin in solution by 50-60% within 15 min, and by 70-80% after 120min. Addition of (2.5%) NuFeed® increased adsorption by removing about 80%of the free solution ochratoxin by 15min and 94% by 120 min.

 

 

 

Experiment Two

 

The second study investigated NuFeed® absorbency in an artificial gastric juice on the aflatoxins BI, B2,G1 and G2 each at 50 and 100ng/ ml (equivalent to 50 and 100 mg toxin/ kg feed respectively)

NuFeed® was added at 1% and 2.5% levels.

At 1%NuFeed®all free Aflatoxin B1 and G1 in solution was removed within 15 minutes and 98% of Aflatoxins B2 and G2.

 

 

 

HOW TO USE NuFeed®

 

Simply mix 0.25% to 5% (w/w) with rations and feed normally. Addition rates depend on circumstances and objectives; New Zealand dairy cows have been fed as much as 1 kg NuFeed®/ day (6.25%addition rate) over summer with no side-effects.

 

• NuFeed® added to calf meal has resulted in a significant reduction in scours.

 

• NuFeed® is an excellent carrier and can be amended to carry ration additives.

 

• NuFeed® improves egg shell quality in molted layer birds.

 

• The fine particle size of NuFeed® ensures easy mixing and additions assist pelleting processes and enhance pellet strength.

 

• NuFeed®is available in loose bulk, bulk bags, and 25kg bags.

 

• A natural product

 

• Small particle size aids mixing

 

• Pellet strength improves

 

• Pelletising process improved

 

• Inclusion of NuFeed® into rations is cost effective. Please see your local NuFeed® representative for pricing.
