Abstract
Aim: To evaluate the rumen
magnet given once a life as a prophylaxis of hardware disease in
buffaloes.
Materials and Methods: In the present study, 3100 buffaloes
were divided into two groups. In group I, 1200 hardware diseased
buffaloes were surgically treated with rumenotomy, given reticular
magnets and followed up to 7 years for a possible recurrent
hardware disease. In group II, 1900 clinically normal buffalo
heifers were given rumen magnets orally then followed up to seven
years for a possible occurrence of hardware disease. All buffaloes
showed signs of hardware disease were treated by rumenotomy. Data
were statistically analyzed using chi-square test.
Results: Hardware disease was recorded in 110 animals
(10.8%) and 155 animals (8.9%) in groups I and II. The incidence
of developing a hardware disease during the first 4 years after
the use of magnet was 0% in both groups. Starting from 5th year, a
time dependent increase in the proportion of buffaloes developing
a hardware disease was noticed in both groups (P < 0.05). The use
of magnets in group I provided the same level of protection as
that of group II since the overall proportions of the occurrence
of hardware disease during 7 years post magnet use were not
statistically different (P > 0.05).
Conclusion: Administration of a rumen magnet is an
effective prophylaxis for hardware disease and reapplication of a
second new magnet is recommended four years later in buffaloes at
high risk.
Keywords: buffaloes, hardware disease, rumen magnet,
rumenotomy, sharp foreign body syndrome.
