 the head and neck. 



NASAL CATARRH OF THE SHEEP 



Nasal catarrh is not infrequent among sheep exposed to the rain and 

 dampness during cold weather. Wliile it is not particularly dangerous, 

 it is disagreeable and will prove dangerous if the exciting causes are 

 continued. 



With catarrh a discharge comes from the nostrils and the sheep be- 

 come unthrifty. 



Open fleeced sheep are more likely to develop catarrh than those 

 possessing compact fleece. 



TREATMENT 



Pine tar smeared on the nose is of some benefit. A tablespoonful 

 may prove beneficial if given internally. It is advisable to sell the 

 cases that have become chronic and make all effort to protect the sheep 

 from damp snows and rains. 



GRUBS IN THE HEAD 



Grubs can be found in the head of most sheep after the summer 

 months, but probably do not cause as much irritation as some people 

 think. Grubs are the larvae of the gad fly. The gad fly lays her eggs 

 in the nostrils and these nostril openings run to points even and between 

 the eyes and the grub works his way into the head. 



TREATMENT 



Bore a number of II/2 to 2 inch augur holes in a log, fill them nearly 

 full of salt and smear the edges with pinle tar and as the sheep eat the 

 salt they will smear their noses with tar which will keep away the fly. 

 This plan should begin about May 15 and be continued throughout the 

 summer. Some smear the tar on the sheeps nose every two or three days 

 to keep away the fly. 



I am of the opinion that grubs of the head do not cause as much an- 

 noyance as some people think, since post-mortem examination of the heads
