56. In North Bihar Range, the blood virus method was
abandoned after 1,372 animals including 45 buffaloes were
immunised by it in 4 districts (Saran, Champaran, Darbhanga
and Purnea) against 226 done in the previous year. With
goat tissue virus, 40,558 animals including 4,353 buffaloes were
immunised and out of these, 58 including 11 buffaloes died.
The Champaran district had the record number of 16,440
inoculations. This method of immunisation is stated to be
now very popular and is being cordially welcomed by the local
bodies of the Range.

57. In the Central Range, the tissue virus work was
undertaken on a big scale with the definite object of stopping
the outbreaks of rinderpest by giving bovines and buffaloes a
long standing immunity. The work was therefore done in all
the districts, and by almost all the veterinary assistant surgeons.
It is gaining in popularity among the villagers of the range.

Altogether 94,697 animals including 11,075 buffaloes were
immunised by blood, as well as tissue virus in 532 villages. Of
these, 649 were done by blood virus. The figures include the
work of the (Veterinary) Disease Investigation Officer also as
shown below.

58. In the Orissa Range, out of a total of 26,507 animals,
14,916 were immunised by the goat blood virus method in the
districts of Cuttack, Puri, Angul, Singhbhum and Sambalpur.
The tissue virus method could not be adopted in this range
sufficiently early with the result that not more than 11,591
animals including 18 buffaloes were immunised in the course of
2 months during the year. None of the inoculated animals
died although most of them showed decided normal reaction.

59. The (Veterinary) Disease Investigation Officer carried
out 4,723 inoculations by the goat tissue virus alone method
including 346 buffaloes. Goat virus work has, so far, been
conducted in the absence of outbreaks. This in itself is very
satisfactory as it gives an effective protection to healthy animals
against a possible outbreak. But in order to derive full benefit
from the operation, it should also be carried out in actual
outbreaks, so as to gradually do away with anti-rinderpest
serum. An experiment was therefore made by the (Veterinary)
Disease Investigation Officer by inoculating out of the total
number, 672 animals (80 buffaloes and 592 bovines) in the face
of actual outbreaks of rinderpest. The result was that, while
there was no mortality among the inoculated in the absence of
outbreaks, the mortality in face of outbreaks amounted to
2.6 per cent for buffaloes and bovines combined. This
mortality was due apparently either to the animals being then
in the incubation period of the disease, or to the inoculated ones
