Healthy Hooves
  • Footbath solution for Buffalo and Dairy Cows

Introduction

Lameness is highly prevalent within the dairy cattle sector and has significant economic and welfare implications (Green et al, 2002). Approximately 20 to 25% of all cases of lameness worldwide are attributable to digital dermatitis (DD), and in the UK approximately 70% of dairy farms are affected with DD (Laven, 2003). Digital dermatitis is a multi factorial disease defined as a circumscribed, erosive to papillomatous, intensely painful lesion that is often surrounded by a ridge of hyperkeratotic skin bearing hypertrophied hairs and is associated with lameness (Teixera et al, 2010). Formaldehyde or Copper Sulphate are commonly used as footbath solutions with varying results dependant of farm management.

Formaldehyde is a sensitizing agent that can cause an immune system response upon initial exposure. It is also a suspected carcinogen. Copper is a heavy metal that raises environmental issues when used at a high percentage in animal footbaths.

Healthy Hooves enables Copper Sulphate to be reduced by up to 80%, resulting in a more effective footbath solution, which activates copper to be more effective against bacteria, allowing for more cow passes per footbath and is safer than Formaldehyde.

  • Healthy Hooves® uses a US patented, low pH, triple buffered formula. A 2% solution will effectively dissolve copper sulphate resulting in a chemically chelated compound. Healthy Hooves® maintains a pH of 2.0 in the footbath to keep the copper at a maximum of 85% solubility that yields more actively available copper to attack bacteria.

    Healthy Hooves® overcomes the solubility issue and more importantly, controls the release of the cupric ion (Cu ++). Copper is released by biological demand instead of the water conditions. As solubility increases, copper remains bio-available there by reducing copper sulphate use by 80% or more.

    The critical difference between copper sulphate dissolved in water and copper sulphate dissolved in Healthy Hooves® is the degree of toxicologically active copper complexes that are formed. Because of the abundance of hydrogen ions in the Healthy Hooves® product, predictably higher concentrations of active copper complexes (Cu2+ ) are held in suspension in a stable weak field chelated chemical bond, thus preventing the precipitation problem that is common with copper sulphate in water alone.

    When copper sulphate is dissolved in water, the copper must be solublised, or chemically changed to a stable, bio available chemically active form before it can predictably kill micro-organisms. The extent of these chemical changes is now possible to predict. Field trials with Healthy Hooves® show the buffered low pH, solublises copper to make it predictably bio-available to control bacteria. Thus, the copper concentration can be precisely predicted with Healthy Hooves®.

    Healthy Hooves® maintains a consistently low pH through a triple-acid buffered system that maintains the pH and reduces copper sulphate use by up to 85% over copper sulphate alone in water. Healthy Hooves® saves the farmer money while meeting anticipated compliance regulations on copper use.

    Healthy Hooves® also eliminates the hazards of formalin while cost effectively minimising the effect of PDD

  • What do Veterinarians recommend? – TREATMENT of PDD?

    • A tropical anti-biotic therapy with light wrap for 3-5 days will generally resolve all but the most advanced infection
    • Vaccines are being used but irregular results

    What do Veterinarians recommend? – PREVENTION of PDD?

    • Veterinary studies have shown that a consistent use of a footbath with either formaldehyde or copper sulphate as a disinfectant, will show positive impact in the prevention of PDD in dairy cows
    • Footbaths must be properly maintained to effectively prevent contamination which would reduce the effect of both formaldehyde and copper sulphate

    Formaldehyde is…

    • A suspected carcinogen and known respiratory and contact irritant, formaldehyde use is regulated by EU in ALL Countries
    • When mixed with water, is effective for 75-150 cows before recharging the solution
    • Ineffective at temperatures below 10°C

    Copper Sulphate Alone is…

    • Effective in preventing PDD, but large amounts are required
    • Copper sulphate is limited in solubility, and as such the footbath must be replaced with fresh copper sulphate solution usually every 200 cows, or more often depending on footbath management practices

    Healthy Hooves® is…

    • A low pH, patented, triple buffered formula that allows 85% of the copper sulphate to dissolve thus maintaining more of the active cupric-ion bio in solution
    • A cost effective part of managing the health of your dairy herd
    • Effective for up to 500 cows before the footbath solution is replaced
    • Effective at any temperature above 2°C
  • The Dangers of Formaldehyde

    Eye Contact

    Symptoms: Range from mild irritation to permanent corneal cloudiness and loss of vision. As the concentration increases, the eyes become itchy and watery

    Inhalation

    Symptoms: Low concentration can cause difficulty breathing, burning of the nose and throat, cough and heavy tearing higher concentrations can cause severe coughing, chest tightness and swelling, or spasm in the throat

    Ingestion (eating or drinking)

    Symptoms: Severe irritation of the tissues lining the mouth, throat and stomach Absorption into the blood-stream through the digestive tract can cause damage to the liver or other internal organs

    Skin Contact & Absorption

    Symptoms: Mild irritation to severe dermatitis Acne, sores or abrasions allow formaldehyde to enter the body more readily

    Formaldehyde is a sensitising agent that can cause an immune system response upon initial exposure. It is also a suspected carcinogen that is linked to nasal cancer and lung cancer. Acute exposure is highly irritating to the eyes, nose and throat and can make you cough and wheeze. Subsequent exposure may cause severe allergic reactions of the skin, eyes and respiratory tract. Ingestion of formaldehyde can be fatal, and long term exposure to low levels in the air or on the skin can cause asthma-like respiratory problems and skin irritation such as dermatitis and itching. Concentrations of 100ppm are immediately dangerous to health or life.

  • Clinical Results

    The objective of the study was to compare the effectiveness of using Healthy Hooves® and 2% copper sulphate as a footbath solution, compared with normal farm practice of using a 5% copper sulphate solution, on the incidence and severity of lameness in dairy cattle, and in particular on Papillomatous Digital Dermatitis (PDD).

    Severe – Score 3 6 6 0 0

    A split footbath* was used for the study, the left bath contained a 5% copper sulphate solution changed every two milkings and the right bath a 2% copper sulphate solution + Healthy Hooves® changed every four milkings.

    In addition to the reduction in the incidence of PDD, the severity of lesions was also considerably reduced following 84 days of Test Article Administration. On Day 84, no new PDD lesions were observed, and 31(89%) of the 35 lesions observed at the start of testing had resolved completely. Of the four lesions observed on Day 84, two had improved (one from score 3, one from score 2), and two had remained at score 1.
