Rodibaugh spoke about the
"factors of success" that swine
producers can use to make a segre
gated weaning program work.
They include the amount of antibo
dies in the pig’s sera, age at wean
ing, and how the medication prog
ram is carried out
A big factor is the actual layout
of a so-called “segregated site.”
Some producers break the segrega
tion down to three sites. Site 1 is
the breed gestation and farrowing
she, site 2 is the nursery, and site 3
is the finishing site. A true multiple
segregated site includes site 1, a

Working on factors to boost average daily gam
(ADG) can mean improved gains on the profit
sheet for producers, according to Dr. Alan
Scheldt. DVM, Pfizer technical services. Each
one percent change in ADG can mean an 83-cent
improvement in feed efficiency per ADG per pig,
a 42 cent increase in feed efficiency per pig, an
improvement in mortality in the litter, and other
boosts in overall, long-term profit.
To do so, more attention needs to be paid to the
environment of the pig, according to Scheldt.
Many diseases that arc seen, such as mycoplas
mal pneumonia and mycoplasma Hyopeneumo
niae, can be caused by the following environ
mental conditions:
• Space meansuring less than 6-8 square feet
per Pig
• Greater than ISO-200 pigs for the available
air space
• Frequent mixing of pip -
• Exposure to older groups of pip
• Nonsolid pig partitions
• Less than three cubic feet of space per pig
• Cold environments (cold weather enhances
virus survival)
• Temperature fluctuations of greater than 4
degrees per day (spring and fall are worse times
to control swine diseases)
• Greater than SO parts per million of ammonia
measured in the house.
Scheidt reviewed various vaccines available
for treatments of mycoplasma, including Respi-
Sure. which helps to reduce the severity of lung
lesions as a result of the disease. Also reviewed
was Amphigen, an adjuvant that increases the
immune response of the pig to battle
mycoplasma.
Donna Berry, Pfizer swine industry specialist,
spoke about the benefits of Stafac, a growth
promotant.
Stafac works to kill off the bacteria ir the back
of the pig’s gut while preserving the bacteria that
promotes nutrient use. The active ingredient in
Stafac is Virginiamycin. Stafac helps to improve
ADG, feed efficiency, and bring pigs to market
in less time, regardless of genotype or diet It is
added at 25 grams per ton from SO-140 pounds
per pig and 10 grams per ton at 145-245 pounds
per pig.
Also, Dr. Paul Pitcher, DVM, University of
Pennsylvania at New Bolton Center, told the pro
ducers that by using forward contracting, evi
dence shows there is nearly a SO percent decrease
in variability of production costs.
With the price swings evident in the market in
terms of feed and pices paid for hogs, studies
have shown that hedging provided a “tremend
ous reduction” in variability of receipts—up to
a three-fold decrease in variability, according to
Pitcher.
He told the producers that they must look to
ways to reduce the “marketing disease.”
Pitcher said. "The disease of poor marketing
can be as cosdy as clinical outbreaks of infec
tious disease” on the herd.
