HOW WILL ERADICATION OF CATTLE TICK BENEFIT VETERINARIANS? 163 
examination of blackleg the liver, spleen and kidneys are ap¬ 
parently unaffected. 
Treatment {Prophylactic ).—Free your cattle of ticks by 
either spraying, dipping or mopping with a parasiticide, prefer¬ 
ably the arsenical preparations; place the cattle in a pasture that 
has been vacant for at least one year prior to the transfer. 
Medical treatment is usually unsatisfactory, although in 
chronic cases beneficial results have followed. Purgatives, fol¬ 
lowed by febrifuges in broken doses. Stimulants and tonics are 
recommended. Good nursing is essential; the animal should be 
given a nutritious laxative diet, with plenty of clean and cool 
drinking water, and allowed to rest in a cool, quiet place. 
S. Dodd finds the treatment with Trypan blue a very efficient 
remedy. He states the most favorable results are obtained when 
it is injected at an early stage of the disease. 
I believe the State experiment station last year conducted 
some experiments with Trypan blue, but the experiments were 
not fully tried out; therefore, I am unable to give data regarding 
results. However, in view of the fact that it is not a specific, 
does not render the animal immune; also, the treatment is very 
complicated; it does not seem probable that it will gain much of 
a foothold with the practicing veterinarian.

Note —The theory has been advanced that certain breeds of cattle, especially those 
known as the Brahma or sacred cattle of India, are immune to tick infestation. When 
this important point was announced it attracted world-wide attention, and it was at 
once taken advantage of in the infected area of the United States for. a thorough trial. 
The first herd of this breed of cattle was imported and introduced into the State of 
Texas. They were allowed the use of the range and the bulls were crossed with the 
native stock of that country. It was soon noticed that the American fever tick did not 
infest these animals to such a great extent as they did native cattle, and the owner 
became greatly enthused and observed that even his cross breeds as low as the quarter 
and sixteenth cross failed to carry as many ticks. 
The idea was then announced that these cattle were immune to tick infestation and 
people generally throughout the tick infested area became interested. 
This announcement was of such importance that the United States Government put 
men into the field to investigate and ascertain the facts. It was found that this particular 
breed of cattle was not especially adapted for general use in this country for either beef 
or dairy animals. They develop slowly, the flesh is hard and tough, and they hardly 
produce more milk than is necessary for the calf. 
The question of ticks received close attention. It was found that ticks did infest 
these animals, but probably not to as great an extent as they did native cattle. The skin 
of these animals is exceedingly tough, secreting an abundance of sebum which produces 
an oily and odoriferous condition, which was thought to be offensive to ticks. . The hair 
being short and the skin tough did interfere with tick infestation to a certain extent. 
A series of experiments'proved that these cattle at any cross were subject to tick in¬ 
festation and fever. The cattle and the immunity to ticks has not been w r ell taken in 
this country.
