KALAMAZOO, MI - Two of the
most serious - and costly -
diseases faced by swine producers
today can be effectively and
economically handled with one
antibiotic, a company veterinarian
stated recently before a gathering
of swine practitioners.
According to Dr. Terry Cowan,
technical services veterinarian for
The Upjohn Company, the proper
use of lincomycin can significantly
reduce the severity of cases of
mycoplasmal pneumonia in swine
(MPS), as well as treat and control
swine dysentery.
Dr. Cowan discussed the use of
lincomycin in treating swine
dysentery and mycoplasmal
pneumonia at a swine seminar
held recently at Upjohn’s Brook
Lodge Conference Center in
Augusta, Michigan. The seminar
was attended by key swine
veterinarians from across the
United State.
Dr. Cowan, whose respon
sibilities include offering
veterinary advice and trouble
shooting expertise to producers
and practitioners in the field,
reviewed his own experiences with
lincomycin. “I’m convinced of the
efficacy of lincomycin in the
field,” Dr. Cowan said. “I was
convinced it worked even before I
started working for Upjohn. Now, I
am able to see the results of lin
comycin treatment first-hand and
I know it’s effective as well as
economical for treating
mycoplasmal pneumonia and
controlling swine dysentery in the
long run.”
Dr. Cowan recommends treating

Lincomyein can be used for swine MPS, dysentery
mycoplasmal pneumonia, a
chronic respiratory disease that
makes a pig susceptible to
secondary infections, at an ap
proved level of 200 grams of lin
comycin per ton. Swine dysentery,
an infectious disease of the large
intestine, also called bloody
scours, can be treated with a 100-
gram level of lincomycin per ton of
feed for at least three weeks, and
controlled by a 40-gram per ton
level thereafter.
“My experience indicates that
it’s very economical to treat
mycoplasmal pneumonia with a
lincomycin feed additive in the
starter ration,” Dr. Cowan ex
plained. “As far as the tran
smission of mycoplasmal
pneumonia goes, the period when
pigs are weaned and grouped can
be one of the most stressful times
in their life, thus making them
more susceptible to infection. This
program is cost-effective when you
consider the average feed con
sumption of a pig that is weaned at
three weeks of age.” Dr. Cowan
estimates that such a treatment
program would cost the producer
an average of $1 or less per pig and
potentially pay for itself in reduced
days to market.
The 200-gram level of lin
comycin, according to the
veterinarian, will reduce the
number of infected lobes, and the
size and severity of lesions in pigs
infected by Mycoplasmal hyop
neumoniae, the organism that
causes mycoplasmal pneumonia.
Dr. Cowan also stressed that
lincomycin can be equally cost
effective in both treating and

observed field trials in units with
histories of swine dysentery,” he
explained. “These units co
mingled feeder pigs that had been
purchased at sale bams - just the
sort of pigs that are going to have a
lot of disease problems.” Dr.
Cowan discovered that the per
formance of such pigs given lin
comycin easily outdistanced that
of pigs under the same conditions
given different medications.
“The mortality rate varied from
29 percent for a group on one
product, down to 4 percent for the
group on lincomycin,” Dr. Cowan
said. “And although the efficacy of
the drug shouldn’t be evaluated on
total performance, I believe
overall performance is a reflection
of the success of disease control
and management. The pigs fed
lincomycin certainly showed that
in terms of average daily gain and
feed efficiency.”
In comparing the economics of
lincomycin with other products,
Dr. Cowan also discovered that the
medication was as cost-effective
as other treatment programs. “I
used current retail prices and
manufacturers’ recommended
.dosages to compute the average
treatment cost per pig given a
standard level of infection,” Dr.
Cowan explained. “Lincomycin
was comparable with its com
petitors at $3.77 per pig for swine
dysentery treatment and control.
Some of the programs averaged in
the $5 and $6 range per pig,” he
added.
“Lincomycin is a proven
medication,” Dr. Cowan con-
