DISEASES OF DOMESTIC ANIMALS 593 



stage. Animals showing symptoms should he killed and premises thoroughly 

 disinfected. AU suspected animals must be tested by the agglutination test. 



Those reacting should be quarantined until test negative. Flesh of killed 

 animals may be used for food under supervision. Milk from infected ani- 

 mals must be pasteurized before use. Herd restocked with immune progeny 

 of infected animals, or from uninfected regions. 



Entire males in infected regions should be tested before copulation is 

 permitted, if they react they should be castrated and quarantined until the 

 test is negative. 



The removal of animals from infected districts must not be permitted. 



Infected solipeds should be isolated from other animals, although they may 

 be worked. 



Mammitis. Mastitis. Garget. 



At onset, milk every hour and give frequent massage of udder with full 

 dose of Glauber's salt and common salt. In no case of mastitis is the milk 

 fit for human consumption, it may be boiled for animals, m mild cases, or 

 else boiled and thrown away. Restrict food and water. Attend to abrasions 

 of teats. (See Teats, Fissured, etc.) Also, to abort, either use constant hot 

 fomentations or ice bag, and support udder by bandage and wide band about 

 body. The surgeon should cleanse udder thoroughly and irrigate each quarter 

 of the udder with warm 3 per cent, borax solution through sterile milking 

 tube, in parenchymatous form. After gentle manipulation, draw off fluid in 

 15 minutes. If suppuration threatens, apply mercury binodide ointment (10 

 per cent.). With interstitial form and surrounding edema, puncture swelling 

 in points by actual cautery, avoiding the veins. Then apply boric acid oint- 

 ment (10 per cent.). For suppuration of udder, incise and drain, and, if 

 severe, amputate in part or altogether. In chronic suppuration, the pus 

 poisons the milk; remove teats with scissors for drainage; fatten and kill. 

 Segregate cows and separate milkers in mammitis to avoid infection of sound 

 cows. To prevent mammitis, cleanliness of animal and premises; use of 

 proper stalls, so that teats are not stepped upon; immediate treatment of 

 abrasions of the teats. 



Mammitis, Contagious Streptococcus. 



Curdling of milk on standing, later hard nodule above teat and milk thin 

 and blue. Segregate diseased cows and provide separate milker for them. 

 Cleanliness of udder and compelling milkers to wash hands after each cow 

 is milked wiU prevent spread of the disease. After isolation of sick, disinfect 

 premises and keep newly-bought cows away from exposed cows and infected 

 stable for a month. 



Treat mild cases with warm injection of 3 per cent, boric acid solution in 

 teats. In more severe cases use one per cent, sodium fluoride. Chronic 

 mastitis due to tuberculosis, actinomycosis, botryomycosis. Also mastitis 

 caused by colon bacilli, B. necrophorus and staphylococci. 

 Mange. Acariasis. Scabies. Itch. Scab. 



In the horse — Sarcoptes scabei, beginning on head, neck and shoulders. Also 

 Dermatodectes communis infesting inner thighs, root of mane and tail, 

 sheath; and Symbiotes equi, seen on feet and pasterns. Clip hair, apply 

 cottonseed oU with 6 per cent, creolin over night. Remove scabs with green 

 soap and water next morning. No better remedy than lime and sulphur dip 

 as for scab in sheep. Rub in one of the following remedies with brush and, 

 when rubbed off by animal, reapply daily for a week. Then wash off and 

 after a few days, repeat the treatment two or three times. Use 1 pint crude 

 petroleum oil, 1 pint oil of tar, 3 quarts white rose oil, mix; or liquid tar 

 and sulphur, each gi ; with soft soap and alcohol, each Sii ; or creolin and soft 

 soap each gi; alcohol gviii. Also balsam of Peru and sulphur ointment, (1 to 

 7), 3 per cent, lysol or creolin solutions. Ointments in localized mange. In 

 dermodectic and symbiotic mange, milder remedies — Peruvian balsam, car- 

 bolic soap, or creolin and glycerin (1 to 10). 



In Dogs — Follicular mange, caused by Dermodex folicuiorum, var. canis, 

 attacks head, neck and limbs, invading hair follicles and sebaceous glands;
