Grower-Finisher Barn Management
In a presentation to the London Swine Conference 2012, 10 rules to optimise nursery–grow–finish productivity were discussed, reports Ed Barrie, Sow Weaner Pig Specialist at Ontario Ministry of Food, Agriculture and Rural Affairs (OMAFRA) in that organisation’s Pork News and Views newsletter.The actual practice of barn management especially
in larger barns, has long been a subject of
discussion. One of the basic principals of providing
proper care for an animal is that it must
be seen, its needs assessed and if required,
corrective action be taken immediately.
In a presentation to the London Swine Conference
2012, 10 rules to optimise nursery–grow–finish productivity were discussed. Greg
Wideman and John Otten of Southwest Ontario
Veterinary Services and Dallas Reimer of Minor
Brothers Farm Supply covered the topic of
‘High Quality Daily Chores, Walking the Barn,
and Individual Pig Treatments’ in a very detailed
presentation of some of the necessary activities.
The importance of addressing the needs of
each pig begins with seeing the pig. Needs for
feed, water, air and health management have
to be examined and considered on the daily
walk through. They suggest a morning and
afternoon walk through with careful observation
of individual pigs being the focus of the
morning walk through. This, if carried out
properly, means the afternoon walk through
is less focussed on the individual animal and
more of a visual appraisal of the feed, water and
ventilation basics.
Upon entry to a barn, it is important
to stop and understand what the barn
is telling you. Observation skills are critical
and involve the use of sight, smell, sound and
sensory skills. Is the temperature correct and
is the humidity in reasonable range? Are the
fans, inlets, outlets and curtains all working? Is
there feed in all the feeders as you pass? Is the
feed delivery system making unusual sounds or
running empty? Smells that are not normal can
reflect overheated electrical components, as
well as an outbreak of diarrhea.
When looking at pens, many of the same
observations should be made. Is there feed in
the feeder and the pan? Is it too much or too
little? Are the drinkers working? Are there
line-ups and fights to get to one drinker? Are
the conditions of the pen floor and walls wet/
dry or visible liquid manure present (diarrhoea)?
Are the animals resting as they are at
any other visit or are they showing lethargic,
agitation or distress?
When looking at pigs, learn to focus quickly on individual animals. Move quickly from
pig to pig so every pig is observed however
briefly. Factors such as posture, location in
the pen, respiration rate, attitude and if you
really know pigs, facial expression. If a pig
is hurting, stressed or sick, it will show. As
extreme as these steps are, with practice, an
experienced stock person can walk a 1,000-head finishing barn in an hour and have a reasonable
idea of the condition of the animals.
In dealing with sickness, the sooner an animal
is treated, the greater the chances of successful
recovery. The only way to locate sick animals
effectively is to go looking for them on a daily
basis. The basic guidelines are if there are
multiple deaths in one day, three consecutive
days of mortality, or increasing amounts of
individual treatments, then call someone – the farm manager, system manager or veterinarian.
