The pulse in cattle and buffalo can be recorded from middle coccygeal artery in tail.
Bovine stomach has four parts i.e. rumen, reticulum, omasum and abomasum
The foreign bodies fall in reticulum through rumino-reticular groove. The reticulum lies immediately behind the diaphragm. If the foreign body is pointed it can pierce through diaphragm into pericardium of heart causing traumatic reticulo-pericarditis. To prevent this, magnet is placed in reticulum so that all the iron objects can stick to magnet.
Medial patellar ligament is incised during stringhalt operation/ saran in buffalo.
