The =pericardium= is attached to the sternum from a point opposite to
the third rib as far as the xiphoid cartilage, and also to the sternal
part of the diaphragm.
The =heart= is small in proportion to the body-weight, especially in fat
animals. It is relatively short and wide. The apex is blunt and is
marked by a notch (Incisura apicis). Its long axis is more oblique, but
it is less asymmetrical with regard to the median plane, than in the
horse or ox. The lower border of the left auricle (appendix) is marked
by several notches and is situated at a lower level than the right one.
The right longitudinal groove is placed far back and there is no
posterior sulcus.
