Deworming

The farmers in field usually do not follow any recommended schedule for deworming. Most of them resort to deworming only when the calf is off-feed or when worms are observed in the faeces. The farmers are required to understand the importance of deworming and follow a recommended schedule for same.

Three most common endoparasitic problems of buffalo calves are ascariasis, strongyloidosis coccidiosis and ectoparasites.

Symptoms

Treatment

Ascariasis

 

The calves with ascariasis remain unthrifty and pass large load of worms in the faeces at periodic intervals. The calves may show convulsions and indigestion as main symptoms and normally pass foul smelling clay colored or watery feces. A characteristic butyric odour may also be detectable in their breath.

Piperazine compounds provide prophylaxis towards all the round worms effectively including Neoascaris. Piperazine hydrate (56.3% w/v) is administered right from day 3 @ 3-6 ml per 10 kg body weight.

 

Micronised albendazole powder 5-10 mg/kg bw per oral may also be given. Second dose is to be given after 21 days. For the first year repeat doses every two months but rotate drug every 2nd or 3rd dose. Thereafter, dosage is to be given thrice a year.

Levamisole (7.5 mg/kg per oral) is another drug of choice. The treatment is repeated every month for first three months and thereafter every two months.

Strongyloidosis

 

Intermittent diarrhoea with blood and mucus is a common feature. Build-up of warm and moist areas should be prevented inside shed.

 

Thiabendazole, levamisole and other broad-spectrum anthelmintics are effective.

 

Coccidiosis

 

There may be sudden onset of severe diarhoea with foul smelling, fluid feces containing mucus and blood. Blood may appear as dark tarry staining of feces or as streaks of clots, or the evacuation may consist entirely of large clots of fresh red blood. Perineum and tail are commonly smeared with blood stained feces. There is a characteristic severe straining and sometimes rectal prolapse may occur.

Amprolium and sulphamethazine@ 10 mg kg-1 and 140 mg kg-1 respectively orally daily for 3-5 days are useful. Same drugs @ 5mg kg-1 and 35 mg kg-1 in feed for 15-20 days are good for prophylaxis. Coccidiosis treatment with sulpha drugs and other coccidiostats is required only when the fecal examination reveals presence of coccidia.

 

Ectoparasites

Excitement, itching, irritation, abscesses on skin 

Cypermethrin (100mg/lit) need to be sprayed on calves and in the paddock. The dosage for ticks, mites and lice is 1 ml/lit of water; for flies is 5 ml/lit of water and for animal housing is 20 ml/lit of water (5 lit of emulsion per 100 sq met surface). This should be sprayed thrice in a year.
