The horns float loosely in theabdominal cavity, and are found closely associated with the con-volutions of the intestines. The broad ligaments are mesentericin conformation and character and are extremely thin and ovaries are decidedly lobulated, and closely resemble grapeclusters, being suspended to the right and left of the vertebralcolumn near the median line of the body. Figure 110 illustrates the external as well as internal generativeorgans of the sow. The abdominal wall in the flank region is quite thick and con-tains much fat. This fat is encountered between the skin and theexternal oblique abdominal muscle. More fat is encountered inmature sows than in younger hogs. The skin is dense and tough.

This operation calls for the simple and easily applied ratherthan the complicated and intrinsic methods oftentimes employedin other operations. The method of restraint used must, of course,depend upon whether the flank or the belly operation is to be per-formed. 720 DISEASES OF SWINE If the abdominal cavity is to be invaded from below (belly), themost simple and satisfa
