Mr. MOTHERWELL:

I have been so
busy with certain other phases of the live stock question that I am sure I will be excused for not going back to hog cholera until I was asked to do so. However, I have a statement here and I do not know how good my hon. friend from South Oxford (Mr. Sutherland) will consider the authority. The statement reads:
Reasons for not permitting the use of double treatment for hog cholera in Canada. The double treatment means the simultaneous injection of hogs cholera serum and the active virus of the disease.
1. Double treatment perpetuates the disease.
Every double treated hog is a carrier of the
virus for an indefinite period after the treatment, and during that time may convey the disease to susceptible hogs.
That is better put than what I said yesterday, but the meaning is the same:
2. Double treatment sometimes causes outbreaks of hog cholera. Experience of the United States shows heavy losses from so-called "breaks" after treatment.
3. Double treatment may disseminate other diseases. During the outbreak of foot-and-mouth disease in the United States in 1914-15, the disease was spread in some instances by this means.
4. Double treatment is unnecessary in Canada as losses from this disease are very small.
There is my authority. I have no doubt the disease is serious in spots. In the West about ten years ago I saw outbreaks that were exceedingly serious. The disease may exist there now, but I have not seen any cases of it recently:

During the past year only 429 hogs were destroyed for hog cholera in all Canada. Compare this with the average annual loss in the United States for three years of $55,000,000.
Of course, we must take into consideration the difference in population. I have not figured that out, neither has Dr. Torrance.
5. Control of hog cholera by immunization when once begun must be kept up indefinitely. All young hogs in double-treated herds must be treated or disease will appear. The cost of this to hog growers in the United States amounts to $7,500,000 a year for serum and virus, not counting payment to veterinarians applying the treatment.
Serum and virus alone cost $7,500,000. Travelling expenses in administering this serum must be enormous.
