Nature and Incidence of Helminth Infection in Cattle
ACKNOWLEDGEMENTS
Our grateful acknowledgements are due to the
authorities of the Imperial Council of Agricultural
Research for the facilities offered to carry out the
investigations at Lucknow. The genus is being
named after Sir Arthur Olver whose unfailing
interest in the improvement of cattle in India had
made possible the sanction of the present Scheme at
Lucknow.

RESULTS OF A SURVEY ON THE NATURE AND INCIDENCE OF HELMINTH
INFECTION IN CATTLE, GOATS AND SHEEP IN THE CENTRAL
PROVINCES AND BERAR AND CENTRAL INDIA

A SCHEME of research at Nagpur was sanctioned
by the Imperial Council of Agricultural Research in
May, 1940. The work in connection with the
scheme commenced in September, 1940 and closed
on 31 March 1943. The programme of work under
this scheme was restricted to the investigation of
(i) the nature of helminth infection and (ii) the
incidence of infection in goats, sheep and cattle.
During the continuance of this scheme, parasites
sent to us from the Veterinary Departments of
Baroda, Bombay and the Central Provinces and
Berar were identified; samples of fæces were
examined and a few parasites from poultry were
also collected and identified. This paper embodies
the results of the survey with reference only to
goats, sheep and cattle. From its very nature, it is
evident that the work is mainly statistical.
MATERIAL AND METHOD
For the purpose of this survey, collections were
made at Nagpur, Jubbulpore, Raipur, Hoshangabad,
Narsingpur, all in the Central Provinces, at Amraoti
in Berar, and at Indore and Mhow in Central India.
Viscera of animals was obtained from the municipal
slaughterhouses and
thorough examinations for
parasites were made. A fairly large number of
animals of each kind have been examined and the
examinations carried out in different seasons. These
factors, in the author's opinion, have made the
results reliable and instructive. The number of
animals examined at each place is given in Table I.
