Experiences with the best additives for feed and slurry have now been gathered in one concept – Nu*Add.

Nu*Add consists of active ingredients that have shown documented effects on health- and performance in official feed trials with pigs and poultry. These are combined with active ingredients that in practical tests have shown the ability to interfere with the normal slurry processes, leading to more homogeneous slurry, together with a reduction in the development of domestic flies and bad odours from the slurry. The fact that the concentration of bad smelling and dangerous gasses are lowered in the stable, reduces the health risks for both humans and animals that have to be in the stable 24 hours or less a day.

Nu*Add is offered in 3 variations: Nu*Add, Nu*Add+ and Nu*Add-booster!

Nu*Add + feed additive

Nu*Add is the basis to the concept and is a pure natural product derived from a variety of plants each having characteristic properties. Common to them all is that they are rich in natural enzymes and sugars with ability to produce mucosa. Enzymes are characteristic in their ability to participate in biological processes again and again. Nu*Add has its effect in the digestive tract and next in the manure that comes from the digestion of the feed stuffs.

Nu*Add +  feed additive

Nu*Add + consists of Nu*Add enriched with the synthetic enzyme glucanase and xylanase that improves the utilisation of the non-starch polysaccharides in the feed. Nu*Add + is also enriched with phytase, which improves the utilisation of the natural phosphorous contents in grains especially.

Nu*Add -booster + slurry additive

As mentioned Nu*Add and Nu*Add + have been developed to improve the metabolising process in the digestive tract and the slurry. Better gut health and feed utilisation is achieved immediately, but the changes in the processes in the slurry have to await satisfactory high concentration of enzymes. Under normal conditions in the slurry this change in processes will take place about one month after the start with admixture of Nu*Add or Nu*Add + in the feed.
To obtain an immediate improvement of the homogeneity in the slurry, the production of domestic flies and bad odours in the confinement, you have to supply the liquid Nu*Add -booster directly to the slurry. At the most optimal pH-value and temperature in the slurry, small bubbles can be seen on the surface within 1 week after application of Nu*Add -booster.

Benefits from admixture of Nu*Add in animal feed

Feed additive

Nu*Add exclusively contains natural ingredients such as enzymes and mucopoly-saccharides that have shown documented effects on weaning-diarrhoea in piglets. The treatment frequency with antibiotics was reduced from 47% in the control group to 11% in the test group. The saved medicine costs alone could pay for the admixture of Nu*Add. On top of this there are benefits in growth and fertilisation.

Danish trials with grower and finisher pigs showed a 3% better feed utilisation. The overall economic performance was 17% better in the test group compared to the control group. These are the best results ever since 1995 where the National Committee for Pig production started tests of feed additives.

In German trials with broilers the feed utilisation was reduced 3% and the end weight increased 6% at the same age. In tests with pigs and broilers the active ingredients in Nu*Add showed better effect compared to the antibiotic growth promoter Maxus G (Avilamycin).

In practical Danish pig herds Nu*Add has shown to have effect on the frequency of gut bleeding (L.I.) and in corresponding Spanish trials the mortality caused by ulcers was reduced. Due to ultra-fine grinding of the feed, ulcers are a problem in Spanish pig production.

Nu*Add + has been added NSP-enzymes, which improve the utilisation of the non-starch sugars in the grain. The passage time of the feed in the digestive tract is prolonged due to lower viscosity. Foreign tests have shown 3-5% better feed utilisation by adding NSP-enzymes to broiler- and pig feed.

Admixture of 2 kg Nu*Add + per ton complete feed adds 150 beta-glucanase-units (BGU) and 5.800 Endo-xylanase-units (EXU) per kg complete feed. Nu*Add + is also enriched with phytase-enzyme, which helps the utilisation of the phytine-bound phosphorus in vegetable feed stuffs. The addition of inorganic phosphorus (MCP) is thereby significantly reduced. Saved costs for MCP in the feed can pay for the price of the phytase, and at the same time the environment is protected against a phosphorus surplus, which the plants can not utilise. Adding phytase-enzyme also results in a better utilisation of other nutrients than phosphorus since the animal’s digestion is avoiding the heavily soluble inorganic phosphorus.

Admixture of 2 kg Nu*Add + pr. ton complete feed adds 650 phytase-units (FTU) per kg complete feed.

Slurry additive

Nu*Add -booster has been tested as slurry additive in the Netherlands for 10 years and in Denmark for the past 6 years, where the product has shown convincing results when added directly to the slurry.

160 different chemical combinations have been confirmed to be the cause for bad odour from slurry. They all have in common, that they contain either nitrogen or sulphur. The most discussed is ammonia, laughing gas and hydrogen sulphide, as they are unhealthy and even very poisonous in high concentrations. Bad odour from slurry is not quoted equally dependent of who is the owner of the nose and their interest in the animal production, from where it originates. Everybody though can agree upon the fact that it is not Chanel No. 5! Not only does slurry smell badly, but
on top of this the smell represents a loss of nitrogen that in Denmark equals a value of ½ billion DKK, if it was possible to utilise in the plant production.

Politically Danish animal husbandry has got a not very kind advice concerning a desire to get the smell from flowers instead of slurry in the month of May. The farmers can choose either to invest in high-tech separations, decanter centrifuge and bio-gas plants that do not solve the problem with bad and dangerous gasses in the buildings where animals are kept on top of the slurry channels. The farmers are now offered the opportunity to put activity in the slurry by adding Nu*Add to the feed and/or Nu*Add -booster to the slurry. The nutrients – nitrogen and sulphur – are retained in the slurry until it is brought to the field in spring.

At an early practical field-test with barley on black sandy soil performed on a farm near Vildbjerg in 1998, the farmer registered a 30-40% higher grain yield from the part of the field where to the treated slurry was brought compared to untreated slurry. The crude protein was 20% higher in the barley from the treated area compared to the untreated.

A green account from a pig farm near Horsens where Nu*Add -booster has been used as slurry additive for 3 years, but now only Nu*Add + is added to all feed, shows a nitrogen surplus of 120 kg N per ha. compared to the Danish average of 188 kg N pr. ha. Analyses of the slurry from the production show considerably higher content of ammonium nitrogen (NH4) in the treated slurry.
