388. Cattle are required to be identified for a variety of reasons and there is a need for a method that is tamperproof and does not raise welfare concerns.
389. The commonest method of identification is the application of metal or plastic tags in the ear. Currently, the use of micro-chip implants is being studied. Recent work indicates that metal tags cause more damage to the ear than plastic tags and the manner in which metal tags are inserted is more crucial. Whichever type of tag is used, the law requires it to be distance readable'; this is welcomed as it will reduce the need for close handling. The EU Council Regulation 820/97 requires all cattle born in the EU after 1 January 1998 to be identified by a tag in each ear. Detailed rules on eartag characteristics such as size, material and tag details are available from the Agriculture Departments.
390. An ear tag should be lightweight and of a design and material that is easily applied and causes minimal damage to the ear.
391. The site of insertion of the tag in the ear is crucial if unnecessary damage to the ear is to be avoided. The operator should be trained and competent and aware of the damage that can occur if the tag is wrongly applied. Farmers should familiarise themselves with the MAFF booklet Earmarking of cattle'; PB2380.
392. The use of micro-chips which cause little discomfort when inserted under the skin should be pursued, although visual identification will still be required.
393. As there is a risk of a fly strike to calves kept outdoors in summer soon after application of the tag, fly control measures should be taken and calves should be checked frequently.
394. Research should be carried out into the type of tag most likely to remain permanently in the ear and least likely to cause damage by tearing, and into other more welfare-friendly methods of individual marking.
