Animal Husbandry and Fishery
Name of Animal / Disease / Control measures
Cattle and
Buffalo / FMD & POX / Seasonal variation may cause outbreak of FMD & POX in large ruminants. Vaccination against these diseases (self/through ARD Dept.) Will ensure better health and production. Anthelminitics of course for animals in proper doses is admissible for better production potentials. Sanitary measures in the cattle shed ensure better health.
Chicken / pox / Care for day old chiks with proper brooding. Proper ventilation and brooding arrangement reduce the mortality. Immunization against ND (Ranikhet) & pox to all age group of birds is advisable.
Sheep and Goat / Pox virus and PPR / The deadly disease PPR (Pest de petits ruminants) leads to havoc mortality in small ruminants. Precautionary vaccination may be enhance immunity and control the chance of morbidity. Small ruminants are also prone to pox virus. Timely measures (vaccination) ensure less morbidity and mortality.
