| Abstract | ||
| Although the principle of Target Selective Treatment (TST) has become accepted as a valuable tool in reducing the speed of onset of anthelmintic resistance (AR), and a key part of sustainable and holistic integrated management of parasites(SHIMP), the only practical and proven on–farm method developed to date has been the FAMACHA© system of clinical anaemia evaluation. This by its nature is limited to use in the few haematophagous parasites that cause anaemia, especially Haemonchus contortus. The principle of TST can be extended for use against other important internal parasites, provided that the system developed is practical, economical and reasonably indicative of some form of important parasitism. The candidates for an extended TST system have included nasal discharge (for botfly larvae), ocular mucous membranes for anaemia (for haematophagous worms), submandibular oedema or bottle jaw (for haematophagous worms and conical fluke), body condition score (for worms causing loss of condition) and faecal fouling or dag score (for worms causing diarrhoea). Each of these checks have their limitations and problems but for the present they are the only practical ways of deciding which animals will benefit from treatment during routine inspection on the farm. A practical, farmer- friendly guide has been developed to enable users to examine sheep (or goats) rapidly, make effective assessments, identify the likely parasites, identify anthelmintic groups that could be used, use practical systems for temporarily identifying treated animals and to know the limitations of the system. The system has been called the Five Point Check (5•√©) for international, multilingual use and constitutes a further, practical extension of TST. This can make a useful contribution to SHIMP. The new system can be summarised in the slogan ―LEAVE THE BEST and TREAT THE REST‖ and has an important shift in emphasis from identifying animals that need treatment to identifying those that are unlikely to benefit from treatment. Rather than dosing all animals, we advocate ―LOOK BEFORE YOU TREAT". | ||
