 A set of maintained records detailing the occurrence of specific health and welfare disorders which act as a monitor of health and welfare.  The health records may be combined with other records such as medicine and movement records, and the method of recording is not specified.

 

The health records must be kept so as to meet the recording requirements of the scheme.  This means that records must be available for the time of the last assessment or a minimum of one year.  The records are to be used to monitor herd health, and will form the basis of the review of the health plan which must be performed at least annually.

 

In order that the prevalence of health conditions can be determined, it is important that accurate records are kept in accordance with the scheme requirements, including the duration of the condition.  This is achieved by checking and recording the progress, resolution, or regression of major conditions such as mastitis and lameness every seven days.

 

The records will assist farmers in reviewing the health plan and formulating effective health control ensuring good welfare and efficient productivity.

 

    The health records must show:

6.STOCKMANSHIP AND TRAINING

 

To ensure that the person in overall charge of the dairy herd can demonstrate best stockmanship practices in the areas of animal health and welfare, food safety, human health and safety and the environment.  Stockmen will be able to demonstrate that they have the knowledge and practical skills to care for animals in an environment that minimises stress and injury.

 

  A designated person must have overall responsibility for the herd.  The designated person has a      duty to ensure that all staff with responsibility for cows have knowledge of and are aware of the requirements.  This person, or the person deputized for him/her in times of prolonged absence      (including relief milkers), must be able to        manage dairy farm activities effectively and competently.  He/she will be           responsible for the record keeping requirements of the scheme.

 

  Farmers and stockmen must follow good welfare practice which recognizes the FIVE FREEDOMS.      These are as listed below:

 

- FREEDOM FROM HUNGER AND THIRST;

- FREEDOM FROM DISCOMFORT;

- FREEDOM FORM PAIN, INJURY OR DISEASE;

- FREEDOM TO PERFORM NORMAL PATTERNS OF BEHAVIOUR, AND

- FREEDOM FROM FEAR OR DISTRESS.

 

  All livestock must be inspected at least once a day.

  Competent persons must inspect lactating cows at least twice a day.

  Stockmen must follow good welfare practice and must observe all relevant codes of practice.

  Staff undertaking veterinary related tasks must recognize the Five Freedoms, in particular the potential to cause suffering.  It is recommended that the advice of a veterinary surgeon is sought for training for specialist courses.

 

In addition:

 

Staff carrying out veterinary related tasks should be able to demonstrate competency.  This particularly applies where they are responsible for procedures that have the potential to cause suffering (e.g. debudding, castration, dehorning, and removal of supernumerary teats of a calf less than three months).  A suitable and effective local anaesthetic must be used for all debudding and dehorning and for castration of animals over two months.  Removal of supernumerary teats for calves over three months must be done by a veterinary surgeon.  Tail docking, hot branding and amputations are prohibited.

 

Staff must observe the regulations concerning the transport of and/or slaughter on-farm of casualty animals, and in particular:

 

  not cause or permit an animal to be transported in a way which causes or is likely to    cause injury      or unnecessary suffering to the animal;

  only transport an unfit animal to the nearest place for veterinary treatment, or the nearest place available for slaughter if the animal is not likely to be subject to further unnecessary suffering;

  if the animal is in severe pain that is uncontrollable, the animal must be slaughtered on farm without delay.

 

Whilst the welfare of cattle after leaving the farm may not be under the stockman's control, cattle markets, abbatoirs and hauliers should be selected with care.  All parties should follow good welfare practice and observe all relevant legislation and codes of practice.  This requirement includes the farmer, if he transports his own cattle.  Appropriate movement/transport records should be kept.

 

 

7. CONTINGENCY PROCEDURES

 

  A list of emergency contact telephone numbers must be displayed in a prominent position.

  Contingency procedures must be in place and known to all stockmen to deal with any emergency which may endanger human or animal health, welfare or food safety.

  Contingency procedures should be in place for the loss of water and electricity.

  Provision should be made to avoid cattle being exposed to extreme weather and      temperature over prolonged periods.
