OPERATING INSTRUCTION

FOREWORD

The cooper improved cattle spray race has been developed to provide the cattle owner with an efficient and economical unit. Its high throughput of spray wash (54,000 to 72,000 liters per hour),specially designed nozzles of large aperture, excellent spray coverage and ease of attachment ,give thorough overall  wetting of cattle of all ages, size and breed, and the improved filter system ensures trouble free service.

The cooper improved cattle spray race makes it possible to deal with up to 600 cattle an hour and avoids many hazards of dipping in the traditional plunge dipping tank. The use of freshly prepared dip wash on each occasion ensures the maximum efficiency of the modern synthetic insecticides, which may be alternated at will without unduly heavy expenditure.                                                                                             

1. MANAGEMENT OF MECHANICAL SPRAY RACES

The mechanical spraying of cattle for tick control by means of specially power operated, spray races, as an alternative to control immersion dipping of cattle in tanks, has much to commend it and is being used extensively in this country.

2. SPRAY RACE SITE

The choice of site on which to erect the spray race is of great importance. It should be as close as possible to a permanent water supply, avoiding the risk of polluting water-ways through flooding be erected across a slight slope with the sump on the lower side and be placed at least 100 meters from daily buildings because ixodioides may cause milk taint. Ideally the race should be erected at right angles to the direction of the prevailing winds so as to keep dd loss of spray wash through wind and be clear of trees to avoid leaves, etc., falling into the sump to cause nozzle blockage.

3. GENERAL CONSTRUCTION PRINCIPLES

The constructional and operational instructions issued with each other reputable spray race must be studied and followed closely in order to ensure correct construction and optimum performance.

4. FLEXIBILITY AND ECONOMY

The application of insecticidal washes through spray races has the great advantage that is possible to use freshly made up spray-wash of a known concentration. Thus the problems of check analyses of washes are unnecessary providing the products are used as recommended.

The second major advantage of spraying is the fact that only required quantities of spray wash need be made up at time. Although the stock farmer is therefore in a position to change over at any time to specific and economic ixodicides for the control of his particular tick problem without the need for the control of his particular tick problem without the need for the financial loss from having to discard thousands of liters of wash, as is the case with dipping, the need for this change over is unnecessary where the best is used at all times.wdf
