patch is used to prevent further tearing. A wire ring is attached to the 

 outside about 4 in. below the sht to hold the conduit open. By the use of 

 webbing straps attached to the conduit and a thin metal strip attached to 

 the outside top of the conduit, the split end of the conduit is secured 

 around the vulva and sealed with branding cement. The arrangement 

 can perhaps best be visualized by reference to Fig. 4-15, which illustrates

 with paper, and galvanized tray under whole unit to prevent contamination of the

its use with swine. The conduit is given additional support by means of 

 a small cord attached to the side of the stand, and a small weight attached 

 to the bottom of the tube serves to keep it in the carboy (see Fig. 4-12). 

 The tail is prevented from interfering by a pulley arrangement that holds 

 it out of the way. Figure 4-12 illustrates the metabolism stand in use 

 with the female, and the features described may be noted. The side par- 

 titions are removable to provide access to the udder for the routine milk- 

 ing of dairy cows. Observe that the entire stand is placed on sheet metal ; 

 this serves to reduce the possibility of contamination of the concrete floor.
