The head is large, and extends beyond the adjoining segments, while the suckers, unlike those of Tcenia expansa, are round. Taenia Planissima, or Denticulata.âThis worm ranges from 3 to 6 feet in length only, and is characterized by a serrated edge, which is due to the overlapping of each anterior segment. The head is by no means large, and the suckers are slightly elongated. Symptoms.âThe presence of tapeworms in the ox is seldom suspected until some have been passed with the fseces. If in large numbers, they may cause anaemia, loss of condition, depraved appetite, and diarrhoea.

Treatment.âAs these worms are unarmed, vermicides and purgatives will remove them with little difficulty. Lysol, turpentine, male-fern, areca - nut, given in linseed-oil, are quite efficient. Arsenic, in doses of lo grains daily, may be given to oxen for three or four consecutive days. Strongylus Ventricosus.âThis worm is the inhabitant of the small intestines of cattle and deer. It is a com- paratively small worm, the female reaching only 12 millimetres in length, and the male 6 to 8 millimetres. In the male there is a broad caudal pouch, which is not distinctly trilabiate. In the female the vulva is situated just behind the middle of the body, and is surrounded by a pouch. Professor Penberthy has associated this worm with cases of parasitic gastro-enteritis in cattle and sheep, while other observers regard it as producing no ill-effects..
