Emerging Patterns in the North American Pig Market
There is a widespread trend towards increasing numbers of pigs produced per sow. Ed Barrie, Sow Weaner Pig Specialist explains why and what impacts this may have on the North American pork market in the latest Pork News & Views newsletter from the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA).Through the period of depressed prices in the 
hog industry in recent years, a significant trend 
has emerged. The trend is toward increasing 
numbers of pigs produced per sow. In itself, 
this is not a new phenomenon. When people 
are stressed to generate revenue they tend 
to look more closely at what they are doing. 
They start to question if they are doing tasks 
correctly and they do spend more time and 
attention to the details of getting things done. 
Records are looked at a little more carefully 
and sows producing fewer young than they 
should be are often culled. Because cash–flow 
is tight, often these culled animals are not 
replaced as rapidly as they would be in more 
affluent times. The net result of this action 
is that there is more time available to carry 
out the routine tasks of caring for the other 
remaining animals in the herd. The consequences are that often total herd production 
increases from a reduced number of sows.
This event is not new and has been occurring 
as long as there have been hog cycles. It is the nature of pork producers to try to do a 
little more with the same resources and as 
long as production appears to be close to acceptable levels, the process continues.
What is 
surprising this time is that, in some instances, 
the sow herd has decreased up to four per cent but the 
total pork produced has increased by over six per cent 
on a year–over–year basis.
There are a number of reasons for this increase. 
Developments in swine nutrition have addressed 
past weaknesses and by rearranging nutritional 
programmes such as rebalancing amino acids and 
energy levels, we have clearly increased born 
alive numbers and kept them alive through to 
market weights. 
Similarly, the genetics industry 
has moved forward. Sow sizes have increased, 
following increased nutritional knowledge and 
sows are now able to produce larger litters of 
robust healthy young animals. There have also 
been improvements in semen handling, artificial 
insemination techniques, and more time has 
been spent in the delivering and management of 
the newborns, to ensure their survival.
The Danes, in particular, have been leaders in 
the management of highly prolific sows and 
genetic programmes, while Canadian nutritional 
research has contributed to the improved 
performance of the sow herd. Thirty pigs 
per sow per year was once considered to be 
a wishful goal, and is now being repeatedly 
achieved by large commercial units as well as by
smaller individual producers.
Interestingly, the American National Pork 
Board has established a ‘Sow Lifetime 
Productivity’ working group. The goal of this 
group is to increase the number of ‘quality’ 
pigs a female produces while in the breeding 
herd. The numbers they are applying are an 
increase of 30 per cent over the next seven years to 
the current US breeding herd. The net result 
would be a 30 per cent increase in pig numbers produced from the current sized national herd.
Since both countries’ producers sell into the North American
market, this goal establishes that sow herd
management will take a higher priority in
the goals of remaining competitive in pork
production in Ontario.
