Husk or Hoose in Calves. 



[JAN., 



This treatment has so greatly reduced the mortality that 

 prevention is no longer such an important problem, and, there- 

 fore, preventive measures which have a severe and lasting effect 

 upon the animals should be abandoned. The starving of sus- 

 pected animals for two weeks prior to the birth of the calf has 

 long been advocated, but this measure is no longer considered 

 advisable, as it is better to have cows attacked with the disease 

 once in a while than to decrease the flow from every heavy- 

 milking cow for one to three weeks after she comes fresh by 

 starving her before calving. 



A method which is not quite so sure of reducing the plethoric 

 condition of the cow, but which, neverthless, proves very efficient 

 and is without the slightest permanent injurious effect, is the ad- 

 ministration of i to i J lb. of Epsom salts two or three days 

 prior to calving. In case this has been neglected and a well- 

 nourished, heavy-milking cow has passed through an easy 

 non-exhausting calf birth, the administration of the salts after 

 labour should by no means be neglected. 



Another very good preventive measure, and one easily 

 carried out, is to give the cow plenty of exercise up to the time 

 of calving. Many animals are allowed to run continuously on 

 pastures from the time they go dry until a week or two before 

 calving, when they are transferred to the stable without any 

 subsequent exercise. This is very conducive to the enriching 

 of the blood and the development of the disease. 



Husk or Hoose is a parasitic disease which attacks calves 

 and sometimes lambs. It is caused by small thread-like worms 

 {Strongylus micrurus) in the windpipe, which

I he disease is caused by keeping calves on 



wet, damp land infected with the ova of the parasite, and its pre- 

 vention can be best effected by keeping young animals in 

 autumn off the fields which appear specially liable to convey 

 the disease. The dressing of these fields about July with a 

 medium dressing of lime or with 5 cwt. of salt per acre is
