Improve your livestock drinking water supply

As livestock producers in the USA grow in size, so do the water demands.  It is not always possible, and certainly not cost effective to bring municipal or rural water supplies to the farm, therefore drilling wells to supply water for on-site livestock is the best, and many times only option.  However, if your water supply is less than ideal, this causes potential issues.

We can help.  Ozone is used by many municipalities around the USA to treat drinking water.  As the technology improves we can now bring this same quality of water to your livestock operation cost effectively.  

Drinking Water Disinfection

Ozone and H2O2 can be used to disinfect drinking water on your farm.  Both well water and rural water can benefit from water disinfection.  By reducing bacteria in water cows will be healthier and water will taste better.  Drinkers will grow less bacteria, algae, and require less cleaning.  Livestock will drink more water when treated with ozone or H2O2.

How it works

Well Water

Well water commonly requires treatment to remove minerals or pathogens, even perfect well water may have no bacteria in it when pumped from the ground.  However, without any added disinfection this water can grow bacteria in it as soon as it is flowing through your pipeline and in your tanks.  This bacteria can spread illness, and make for generally unhealthy water in the drinkers.  Bacteria can easily be oxidized by ozone or H2O2, just as it is normally oxidized by chlorine in municipal water supplies.  However, using ozone or H2O2, dissolved oxygen levels in the water will increase and create healthier water without the added chloride contamination.

Common well water uses for ozone

Benefit of Ozone

Ozone can improve water quality to your livestock.  Animals will drink more water if it tastes better and looks better, cows that drink more water will eat more food, therefore, gain weight faster,  and are healthier animals overall.

Reducing bacteria in water will improve herd health and reduce maintenance on drinkers throughout your farm.

Using ozone as opposed to chlorine or H2O2 will save costs as there is no chemicals to purchase.  Ozone equipment is a one-time purchase with only minimal maintenance costs.


Ozone is dissolved into water using an ozone injection system.  The size of ozone system will be based upon your total water flow rate used.  Total water flow may be based on other applications for ozone on your farm or ranch.  See diagram of ozone injection system below for information on how ozone is dissolved into water.

Researching ozone for use in New Zealand dairy industry


Grant could save dairy industry millions

Garth Lovatt has received a grant to research the use of ozone on New Zealand dairy farms

An Auckland man has received a grant that he believes could save the New Zealand dairy industry millions of dollars.

Former engineer Garth Lovatt will travel to Europe, North America, and Asia in April to research the idea of using ozone in a sustainable and profitable dairy model.

Ozone is made up of air and electricity, and could provide a range of benefits to dairy farmers, without negative impact.

The trip will allow Mr Lovatt to research ozone-related technologies for different uses, including as an oxidiser and antimicrobial on dairy farms which would replace antibiotics and pharmaceuticals for the treatment of cattle.

Mr Lovatt said his research could help boost the New Zealand dairy industry by $1 to 1.5 billion dollars annually, with ozone having many benefits in dairy farming.

One of these benefits, he said, was that ozone would prevent losses of dairy cows on farms due to infection.

“If we can correct that [the losses], which I think we can do by using ozone, I have got to go and talk to the manufacturers and researchers that are leading the charge.”

Mr Lovatt will meet individuals and organisations that are already using ozone as an oxidiser and antimicrobial to gain further knowledge on the topic.

The Agricultural and Marketing Research and Development Trust (AGMARDT) awarded the grant to Mr Lovatt, with AGMARDT general manager, Malcolm Nitschke, saying the project was original and revolutionary.

“AGMARDT seek innovative ideas, and we felt this project was considered very innovative, it hadn’t been done before. If it comes off, it could be truly transformational for the industry.”

Ozone, like antibiotics, kills bacteria but does not cause mutations or generate resistant types within the cows – unlike antibiotics.

Because of this and other factors, Mr Lovatt said the use of ozone on dairy farms would allow for sustainability as well as profitability.

The grant given to Mr Lovatt is gaining support for his research from DairyNZ, a company producing research and development for sustainable dairy farming in New Zealand.

DairyNZ’s industry education facilitator, Susan Stokes, said AGMARDT funding added value to the dairy industry by building leadership capability and sponsoring and enabling innovative research.

“This then attracts and retains talented people that will develop creative solutions for the New Zealand dairy industry.”

New study shows iron in dairy drinking water affects milk

Iron in cows drinking water can negatively affect milk quality.

A new study published in the Journal of Dairy Science has proven a link to poor milk quality due to elevated iron levels in drinking water on dairies.  This new information gives more credence to the use of ozone for drinking water treatment on dairy farms.

While we have used ozone for iron removal in drinking water for dairies, along with many other water treatment applications, we did this for improved milk production, and higher water/feed intake reasons.  This new study shows that even the milk produced from cows drinking water with elevated iron is of a lower quality due to iron in the drinking water.

Milk protein composition and stability changes affected by iron in water sources


Water makes up more than 80% of the total weight of milk. However, the influence of water chemistry on the milk proteome has not been extensively studied. The objective was to evaluate interaction of water-sourced iron (low, medium, and high levels) on milk proteome and implications on milk oxidative state and mineral content. Protein composition, oxidative stability, and mineral composition of milk were investigated under conditions of iron ingestion through bovine drinking water (infused) as well as direct iron addition to commercial milk in 2 studies. Four ruminally cannulated cows each received aqueous infusions (based on water consumption of 100 L) of 0, 2, 5, and 12.5 mg/L Fe2+ as ferrous lactate, resulting in doses of 0, 200, 500 or 1,250 mg of Fe/d, in a 4 × 4 Latin square design for a 14-d period. For comparison, ferrous sulfate solution was directly added into commercial retail milk at the same concentrations: control (0 mg of Fe/L), low (2 mg of Fe/L), medium (5 mg of Fe/L), and high (12.5 mg of Fe/L). Two-dimensional electrophoresis coupled with matrix-assisted laser desorption/ionization–tandem time-of-flight (MALDI-TOF/TOF) high-resolution tandem mass spectrometry analysis was applied to characterize milk protein composition. Oxidative stability of milk was evaluated by the thiobarbituric acid reactive substances (TBARS) assay for malondialdehyde, and mineral content was measured by inductively coupled plasma mass spectrometry. For milk from both abomasal infusion of ferrous lactate and direct addition of ferrous sulfate, an iron concentration as low as 2 mg of Fe/L was able to cause oxidative stress in dairy cattle and infused milk, respectively. Abomasal infusion affected both caseins and whey proteins in the milk, whereas direct addition mainly influenced caseins. Although abomasal iron infusion did not significantly affect oxidation state and mineral balance (except iron), it induced oxidized off-flavor and partial degradation of whey proteins. Direct iron addition to milk led to lipid oxidation during storage at 4°C. Oxidation level was positively associated with the concentration of added iron. Minerals (Mg, P, Na, K, Ca, Zn) in milk were not affected by the added iron in milk. This study indicated that a small amount of iron contamination in bovine drinking water at the farm or incidental iron addition from potable water sources causes oxidation, affects milk protein composition and stability, and affects final milk quality.

The Ozone Answer:

Ozone used with filtration can not only efficiently remove iron from drinking water, but also remove manganese, H2S, turbidity, and other taste/odor issues from water.

Ozone used for Hoof Bath in Dairy Farms

Hoof baths are used on dairy farms to treat hoofs of cows.  As cows walk in wet, and poor conditions much of the day it is important to offer a disinfectant to the hoofs to remove diseases.
dairy cow hoof bath

Ozone is dissolved into water at high levels and flows into the hoof bath at a low flow rate.  This new water with high levels of ozone will mix with the water and allow for oxidation of cows hoofs with safe ozone at all times.

Ozone injection systems are used to dissolve high levels of ozone into water.
