Grants for companies developing products in animal nutrition and related areas
Many companies are unaware that they can get up to 40% of their development projects funded from NZ grant bodies. This includes developing the product, testing, lab work and registration. At LWT we have been helping companies develop projects and submit grant applications for a decade. Our links to other specialists in the world of grants and also checking financials before submission make the process much easier and understandable. If you have a new development within the nutrition and allied sectors (including feeding systems, animal health etc.) get in touch to find out how we can help you obtain funding.

CREDENCE FOR CALVES – CLEANING AND DISINFECTING
NEW BREAKTHROUGHS IN WATER SAFETY AND DISINFECTION
CREDENCE – for safe drinking water and clean equipment and facilities for calves
- Water troughs, calfeterias and calf feeders need effective cleaning?
- On a rural water supply?
- Does your rearing facility have a history of disease transmission?
- Do you need an effective, easy to use disinfectant that is safer for animals and humans and less corrosive?
CREDENCE is now available in New Zealand to solve these problems
CREDENCE is effective against toxic bacteria, protozoa, viruses, algae and fungi:
| Listeria monocytogenes | Faecal coliforms | Aspergillus |
| Salmonella | Pseudomonas aeruginosa | Cladosporium |
| E. coli | Clostridium | Citrobacter freundii |
| Campylobacter jejuni | Giardia lambia | Aeromonas hydrophila |
| Shigella sonnei | Leptospira interrogans ser.Icterohaemorrhagiae | Avian influenza virus |
| Staphylococcus aureus | Yersinia enterocolitica | Rotavirus |
| Streptococcus dysgalactiae | Canine parvovirus | Toxigenic cyanobacteria (blue green algae) |
| Klebsiella pneumonia |
TECHNICAL INFORMATION
In trials, Credence was applied as a spray to the bottle and calfeteria teats at a concentration of 1500 mg/l for 5 seconds. Contamination with disease organisms was reduced to to virtually zero. In farm buildings swabs taken over a 15 day period from calf pens showed that Credence is important in maintaining hygiene. Annals of the 23rd Brazilian Congress of Veterinary Medicine recorded that “The use of Credence revealed a quantitative reduction of the bacteria…., which are most times associated with neonatal enteritis, which were isolated from the calves pens, suggesting the efficacy of the product on the environments studied.” As there is increasing concern regarding toxicity from using certain disinfectants on farm, it is reassuring to know that Credence performed excellently in an EU residues study and in a 1995 impact study was confirmed as biodegradeable and environmentally friendly. For full information on the research trials conducted in a variety of species of animals including the control of toxic blue green algae in water, see www.animalnutrition.co.nz/products/credence
WATER CONTAMINATION IN NEW ZEALAND
Research has shown that New Zealand rural water supplies are commonly contaminated with toxic bacteria, protozoa and algae. These cause poor growth, gastroenteritis, neurotoxicity, liver and kidney damage and can be fatal to young animals. Effective cleaning of housing and equipment as well as biosecurity on farm is essential to limit disease exposure. CREDENCE is an effective sanitiser that is highly effective for treating rural water – keeping it free of toxic organisms – and for all your disinfecting and sanitising needs. CREDENCE can be used for cleaning equipment, buildings, concrete yards and for foot baths as part of an effective biosecurity program. CREDENCE is cheaper, safer, more flexible and easier to use than to other sanitisers. Soaking for 15 minutes followed by rinsing with clean water will sanitise according to the concentrations below for CREDENCE 1000 product:
| Use | Litres per tablet |
| Biosecurity/footbaths | 5 |
| Equipment washing | 10 |
| Non-porous surfaces | 15 |
| Hand/udder washing | 100 |
| Water pipes cleanout | 200 |
| Drinking water | 1000 |
LESS CORROSION
CREDENCE is less corrosive than other disinfectants, without compromising effective cleaning. It can be used in water lines in poultry and pig units and dairy sheds.
SAFER FOR ANIMALS
Once cleaned with CREDENCE solution, after a single rinse, sheds and equipment are safe for animal contact. Less worry about cleaning teated bottles or animals chewing wood and licking floors. CREDENCE ORDERING
Ask at your local Farmlands store, vet clinic or rural outlets for CREDENCE. CREDENCE is registered on the approved sanitiser and disinfectant list with MPI NZ

CREDENCE FOR SMALL BLOCK FARMS/LIFESTYLE PROPERTIES
If you own a small block of land, you may own a variety of animals, however all of them need clean, safe water and you will need a way to keep equipment, feed buckets and buildings free of potential pathogens that can cause disease and or poor growth. CREDENCE protects against a multitude of disease-causing organisms. In addition, once cleaned with a stronger solution of CREDENCE, a simple rinse with water will dilute the CREDENCE down to drinking water levels, ensuring it’s safe for animals to ingest. It’s especially useful for tricky equipment such as calfeterias and it can be used as a spray for calf and lamb bottle teats, so they can be used between animals without disease transfer.
A trial was run on bacteria in teats from milk feeder bottles. Credence was applied as a spray to the teats at a concentration of 1500 mg/l for 5 seconds. The teats were swabbed 30 seconds after treatment for colonising bacteria, and compared to rinsing in water alone (66 CFU at tip and 32 CFU at base of teat) or no cleaning (34 at tip and 68 CFU at base of teat). A huge reduction in contamination was seen for the Credence treated teats, down to non-detectable levels. In addition, CREDENCE has excellent penetration of the fatty bio films that build up on feeding equipment, making it safe without manual scrubbing or soaking.
Unclean feed and water buckets are a potential source of disease, as they harbour all kinds of pathogenic micro-organisms which secrete toxins that cause disease. Trials have shown that CREDENCE is an effective disinfectant for all types of feeding troughs and buckets. In the research below, swabs from feed troughs showed 80% contamination before CREDENCE was used to clean them out (<10% contamination). Once the cleaning stopped, troughs were rapidly re-infected, to 100% contamination levels.
Preparing hygienic accommodation for your animals, including kennels and stables, is important for limiting disease exposure. Wooden buildings are an especially risk as the wood may be chewed, although this is not a problem if they have been cleaned with CREDENCE. Laboratory studies using swabs from farm buildings show that CREDENCE is effective at reducing levels of contamination – protecting animals against disease.
| Bacterial contamination | Calf Pen | |
| Control | Credence | |
| High contamination swabs | 62.5% | 11% |
| Uncontaminated swabs | 0% | 53% |
Water troughs and tanks can harbour a multitude of toxin producing organisms, including fungi, algae and bacteria. Samples from troughs fed by treated town water showed that they can still harbour various pathogens that can cause problems in animals. In addition, toxic algal blooms in dams during summer months can be fatal to animals, especially dogs.
| Species | Untreated | Credence 24 hours |
| Pseudomonas | Present | Undetected |
| Campylobacter | Present | Undetected |
| Pseudanabaena (toxic algae) | 1000 CFU/ml | 380 CFU/ml |
| Aphanocapsa (toxic algae) | 1600 CFU/ml | Undetected |
| Phormidium (toxic algae) | 1100 CFU/ml | Undetected |
CREDENCE is a slow release form of chlorine which has good residual effects in water (treatment every 6-8 weeks typically) and effective as a disinfectant solution. In dams it can persist for up to 12 months, keeping water clear of any pathogens. It has none of the negative effects of copper sulphate (blue crystals) which cause mineral overloading leading to brittle bones and toxicity. It is easy to use, very cost effective and less toxic and corrosive than other sanitisers available.

CREDENCE AND PARVOVIRUS CONTROL
Canine parvovirus is an important, potentially fatal, disease that requires control anywhere where vulnerable, unvaccinated or immune-suppressed dogs are kept. This includes breeding facilities, boarding kennels and veterinary clinics. Puppies are at great risk of contracting parvovirus, and all breeding related equipment and buildings must be suitably cleaned and disinfected before whelping to ensure the disease is controlled.
A laboratory trial in the USA was conducted to test the efficacy of Credence sanitiser against Canine Parvovirus (Cornell Strain) ATCC VR-2017. One tablet of Credence was dissolved in 3.8 litres of filter sterilised reagent grade deionised water, and used to test its efficacy against canine parvovirus. The virus was grown on test medium: Eagles minimal essential medium (E-MEM) supplemented with 5% heat-inactivated foetal bovine serum, 10 ug/ml of gentomycin, 100 ug/ml penicillin and 2.5 ug/ml fungizyme. Separate dry virus films were exposed to 2 ml of either water or Credence dilution at room temperature for 10 minutes. Following exposure, viral plating on the test media was conducted to assess viability of the canine parvovirus.
Table 1. Control of canine parvovirus (ATCC VR-2017) by Credence
| Virus Dilution | Control (water) | Credence solution |
| None | Positive | Not detected |
| 10-1 | Positive | Not detected |
| 10-2 | Positive | Not detected |
| 10-3 | Positive | Not detected |
| 10-4 | Positive | Not detected |
| 10-5 | Positive | Not detected |
The results of this study demonstrated that Credence is fully effective against canine parvovirus.
