208 DISEASES OF THE HOG. 
CHAPTER XXIII. 
DISEASES OF THE GENERATIVE ORGANS. 
The pig is not subject to diseases of these organs 
for the same reasons that have been mentioned 
before, that they are brought to maturity and 
the greater number of them sold by the time they 
are two years old or less. 
Difficult Parturition—This is sometimes met 
with in the sow, and on account of the passage be- 
ing too small to admit the hand, in the majority of 
sows, it is sometimes with great difficulty that we 
can relieve them. If a sow has been straining for 
some time and making no progress, it will be nec- 
essary to examine it to find the cause. Causes: The 
parts may not be properly dilated, or the passage 
may be too small to allow the foetus to pass, or 
the parts may not be strong enough to expel the 
foetus. In other cases several may be expelled and 
one or more seem to block up the passage. Every 
_ farmer and stock breeder should have a pair of 
parturition forceps for the pig. They can be ob- 
tained from Frank Wagner & Co., manufacturers 
of revolving and obstetrical instruments, Mans- 
field, Ohio. These instruments are the best in the 
market at the present time.
