A CALENDAR OF LIVESTOCK PARASITES ri 
JULY 
Observe animals for signs of lungworms. 
Treat fowls for worms and lice. 
Spray poultry houses to kill the mites. 
Note condition of your dogs. 
Parasite trouble begins to be serious in July or August, if proper 
precautions have not been taken. Watch for them, and if your 
animals ‘‘don’t do well,’”’ suspect parasites of being the cause. It is 
probably due to poor breeding, poor feeding, or parasites, and if 
you are sure it isn’t the first two it is probably the last. If your 
sheep, calves, or pigs have a husky cough, look out for lungworms.

(Fig. 10.) Infested animals should be isolated and given nursing 
treatment. Consult Farmers’ Bulletin No. 1330 (8). 
Unthrifty dogs, especially pups, may be wormy. Pale linings of 
the mouth and eyelids are an indication of hookworms. Dogs with 
tapeworms may be a menace to you and your livestock. Take your 
sick dog to a competent veterinarian for treatment. Write for 
Department Circular No. 338 (9). 
The best protection against worms and coccidiosis in young ani- 
mals is obtained by the greatest possible cleanliness and sanitation, the 
raising of young stock on clean areas or in clean buildings away from 
older animals and areas used by them, and by sound feeding pro- 
cedures. Good results are reported in connection with coccidiosis 
in chicks from the use of a mash containing 40 per cent dry skim 
milk. High vitality is an aid in protecting animals against many 
parasites and good feeding practice builds up an animal’s condition. 
Vitamins appear to be of value in protecting animals against certain 
worm infestations, and the feeds should contain these essential 
_ substances.
