A few private grazier models are shown, but there are more that are worthy of portrayal. Grazier models previously mentioned are shown in Figures 9 (top), 39, 41 and 42. The model in Figure 9 (top) is a tool made to fit a five foot cattle rub for smaller herds. It is a medium wide track, well-built model for stocker cattle properly designed for multiple uses. The model in Figure 41 is excellent and performs very well to control face and upper body flies.

Figures 41 (top) and 44 show models made of wood and steel. A possible weakness of the model in Figure 41 (bottom) is that is will not wipe insecticide on calves or the middle to lower parts of large cattle. The models in Figures 41 (top) and 44 are excellent tools with all the important characteristics.

Some Noble Foundation models have runners made in a star formation to prevent overzealous cattle from tipping the tool over Figure 9 (bottom). This tool is discussed in more detail by Gentry (2001). This illustration shows the technique of using insecticide ear tags on the cattle rub part of the tool. This technique works fair to good for upper body fly control, but the wetted cattle rubs work better. Fly tags used this way may be less costly than wetted cattle rubs and are less messy. When fly tags are used in summer, other means of lice, tick, and grub control are needed. The star runners allow the tool to be dragged easily from location to location in a paddock or unit on relatively smooth ground. In bunch grass pastures there may be some difficulty when the bunches are large and dense.

The grazier model in Figure 45 is an excellent model with all the needed parameters on this Central Texas ranch. The model shown in Figure 46 on the East Texas ranch is a good one with the feeder roof for cover on the salt/mineral feeder. The cattle rub as set up will wipe the head, neck, back and upper sides of replacement and grown cattle. The cattle rub could be lowered on the far end from the feeder to be accessible to small cattle, and legs and lower sides of larger cattle.

Figure 47 illustrates a model with a tarp covering the feeder for water protection and shade and bait for the cattle. The tool is used on fescue and other forages of Northwest Missouri. Cattle seek the shade and in so doing contact the cattle rub with the face flips. Control of flies on the head, neck and upper body is good. The use of the salt/mineral feeder in immediate juxtaposition to this tool is not employed, but shade is the bait in this case. The same grazier made a combined commercial and homemade tool that performs very well (Figure 48).

A neat tool that combines several commercial external parasite tools on a homemade portable frame is shown in Figure 41 (bottom). This model also incorporates the use of the cattle rub "bullets" on the left.
