Click here to view Document  Water and Feed Me ters and Alarms   Description: Feed and water use are very significant in dicators are extremely significant indicators of pig health and productivity. As pigs grow, they gradually consume more and more. In normal batch production, you should expect to see a gradually rise in use according to a regular pattern. Deviations from this pattern or un usual patterns over the growth period indicate possible problems. For example,poor feed palatability may affect in take. That’s why measuring and logging of feed and water use is so important. The best way to do this is by network logging, with subsequent viewing using the Barn Report service.

Click here to view Document Research  2 Ventilation Failure Incidents   Description: Ventilation failure alarms are typically based on an over temperature trigger
point. Temperature data on prolonged ventilation failure is sparse since monitored
incidents are rare. This paper studies two incidents of prolonged ventilation
failure affecting a group of 8 farrowing rooms and a large dry sow building. It
illustrates the resulting temperatures and questions the efficacy of over
temperature alarm as typically implemented and operated.
In the cases studied, rates of temperature rise fell from an initial value
around 0.1ºC per minute to 0.01ºC per minute within 2 hours.   Click here to view Document  Assessment of Supplementary Heat   Description: This case study illustrates quantitative methods of assessing heating use and capacity, as
well as the underlying factors which affect it in a practical situation.
The characteristic rate of heat loss at minimum ventilation for this room is about 281 W /ºC,
and the effects of marginal changes have been calculated.
In the case studied, heating capacity is barely adequate for the circumstances and
substandard temperatures are liable to occur in colder weather with young pigs unless
minimum ventilation rates are changed.   Click here to view Document  Automatically Controlled, Naturally Ventilated (ACNV) Building Temperature Differences   Description: This is an early, brief, study, but the results suggest that regulation and control would be
achieved by dividing each zone curtain (currently the whole length of the building) into two
parts with a motor on each (that is, 4 zones, one per quarter, instead of the two zones one
each side).   Click here to view Document  Automatically Controlled, Naturally Ventilated (ACNV) Pig Building   Description: This case study was occasioned by an issue raised about temperature differences, after
installation of new Dicam controls. Previous (non-Dicam) controls regulated side to side (as
now), but based on single sensors in the middle of each zone, without temperature displays. The study shows that there are side to side differences, but that the end to end differences -beyond
the control of the regulation system - are greater.   Click here to view Document  Case Study : Ventilation Accident in a Pig Finishing Building   Description: The building concerned holds finishing pigs which were close to slaughter weight.
Natural ventilation curtains were switched off in the fully closed position and left this way for
approximately 56 hours.   Click here to view Document  Comparing Method of Heater Control   Description: This case study compares On-Off heater control with modulating (Simmer) control in flat
decks. The data is taken from sample flat decks on two different farms with Dicam control and
monitor networks. The ages of pigs and general design is similar.
Both farms use dull emitter type electric heaters, but on one farm, the controller is set up for
simmer control and on-off in the other.   Click here to view Document  Creep Lamp Control   Description: Due to the use of open creeps, energy savings are not so great as are readily achievable with
enclosed creeps which permits much better targeting of energy use.
Nevertheless, significant energy reductions are achievable through use of Dicam controls. In practice, costs savings may be more as the ambient temperature dependent reductions are
greater during the day, depending on the tariff structure of the energy supplier. Furthermore,
using higher than necessary creep energy levels during higher daytime temperatures would
mean that extra electrical energy is used in removing the heat by fan ventilation, also at day
time tariff rates.

of time.
The situation appears to have worsened significantly in recent months, though to what extent
it is due to equipment reliability worsening, an increase in timer bypass, or other issues such
as feed composition, is not clear.
Logging indicates a significant number of occasions on which feed intake is judged to have
been deleteriously affected.
As well as increased electrical operating costs, higher equipment wear and loss of production
efficiency are likely to have occurred.   Click here to view Document  Factors effecting Actual Temperatures and Fan Power Requirement   Description: The preceding charts show the (calculated) effect of changing set temperature and
proportional band in a fully stocked pig building in mild spring autumn weather over a period
of two days.
The calculation is based on calculating the closest match of ventilation rate (according to the
set temp and prop band "rules" for the system, and then resulting actual temperature by a
standard calculation. Calculations are based only on ventilation heat loss.)   Click here to view Document  Farrowing Heat Correlation   Description: Farrowing Heat Correlation   Click here to view Document  Feed and water intake in three successive batches of pigs in a single room of a nursery   Description: There appear to be significant differences in outcomes for these three batches of pigs (judged
in the absence of outcome data).
In this case, water intake appears to be strongly influenced by daily maximum temperature -at
higher temperatures, the pigs increase intake significantly but it has an effect on
subsequent eating and drinking patterns.
Significant changes in feed intake occur at what appears to be a change in feed ration. Feed
intake changes are difficult to track in systems with inconsistent daily operation, or where
hoppers are allowed to run out. However, daily water intake changes appear to be a useful
guide (though changes for other reasons must be taken into account), and a 3 to 5 day rolling
average appears to be sound.   Click here to view Document  Feed and Water Shortage   Description: Feed or water shortage is one of the most dangerous and insidious problems in pig
production, accounting for some of the biggest production losses encountered.   Click here to view Document  Feed Changes and Effect on Water Intake   Description: Firstly, It is clear that intake values are very consistent in this production situation - falling
within around 15% of the average value - despite the number of batches, and a range of
environmental and other conditions.
Secondly, that there are two very clear "knees" in the trace- around Days 20 and 35. These
are not mere aberrations of logging, etc. - there is a set back in water intake on these two
occasions. In both cases it takes water intake about 5 days to recover to the previous level.
These correspond to changes in feed ration. (These may not be the only changes in ration,
but they are the ones with clear effects on water intake.) Clearly, there is an interaction
between feed ration and water intake.   Click here to view Document  Feed Control and Alarm Case Study   Description: This is the very first period of logging data on this site, covering only a day and a half, and
reveals problems from the outset with poor reliability in the apparently simple tasks of
delivering feed and water to the pigs.
Most producers would be satisfied with the fact that the feed outage (in U04) was "spotted in
time". On the ground observation would indicate that the pigs then ate their fill, and so there
was nothing to worry about. The data suggests that there was a net loss. Not so great as to
break the bank, and certainly not so much as to cause pig losses, nor even great discomfort,
but a loss nevertheless.   Click here to view Document  Feed Intake Inhibition due to high temperatures   Description: 1 Intake is inhibited once room temperature reaches a certain point, and remains
inhibited until temperature returns to an acceptable level.
2 The degree of inhibition is dependent on temperature.
3 Inhibition due to temperature is indicated by a negative curve in feed intake - the
"double hump" syndrome. This may not be obvious in feed systems, due to their
method of operation.
4 Water intake directly correlates with feed intake. It can be assumed that a negative
curve (double hump) in water use indicates feed inhibition.
5 Once feed intake has been inhibited by high temperature, the effect lasts several
days beyond the removal of high temperatures.
6 Significant economic benefits may be achievable by development of strategies to
avoid or minimise such effects in the order of $10 per finishing pig place. Research
aimed at achieving such improvements is strongly indicated.   Click here to view Document  Feed Outage at Lewis Site (R2)   Description: Feed delivery loss leads to loss of growth on account of lost feed intake.
Of course, this depends on when the feed delivery failure occurs. If it is sometime during the
night and restored first thing in the morning, it appears that feed intake loss if relatively
marginal. However, when feed delivery loss occurs in the morning - or is not corrected in the
morning - it is clear that there is a dramatic and irretrievable loss of feed intake.

Click here to view Document  Loss of Feed Intake : Hidden Cost   Description: This chart shows the estimated cost per pig of a one day loss of feed intake.
Whilst the numbers may seem alarmist, I think they are conservative.
The basis of calculation is very simple (perhaps over simplified). It is based on the length of
time it takes to make up for the maintenance costs.   Click here to view Document  Loss of Growth and Cost Estimation Method   Description: This method compares a batch of pigs with itself, somewhat in the absence of any absolutes
to work from. So, for example, loss of potential can only be estimated if the actual potential is
revealed at least for part of the time.
However, I believe the method has some potential benefits, not least that it is cost effective
and can work from limited data. One of the most useful aspects is that it helps to reveal step
changes in the relationships. It helps to focus - in economic terms - on particular issues and
situations.   Click here to view Document  Maxing Out : a Water Supply Case Study   Description: During the period of logging, the site appears to have lost around 25% of it's water delivery
capacity at the start of site water logging. The site had been in operation for some time
before that, so it is not clear how much capacity may have been lost before that.
Regrettably, site water meter data on this site has been absent for some time, so it is not
possible to determine the outcome as regards whether the situation has been detected and
corrected subsequent to the logging.
This is a study of a single site. One cannot project whether this type of issue may be typical or
otherwise, as there are relatively few sites where a total supply meter has been connected to
Dicam logging.   Click here to view Document  MMR Analysis Exercise   Description: The general results suggest that the MMR technique may be a useful indicator for trends and

This is usually
around 4 or 5 am, when all pigs are asleep or there is a very low level of activity.
Any water use when no pigs are drinking must therefore due to leakage, most commonly from
worn or poor quality drinkers. This shown in Barn Report by a "zero shift".   Click here to view Document  Water Leakage: Baseline Shift Example   Description: The chart has been taken from the very first period of logging in a finisher building holding
900 animals, and shows clear evidence of water leakage/waste amounting to around 9c per
pig in a 24 day period.   Click here to view Document  Water Max Min and Ratio [WMMR]   Description: The WMMR method uses water use data extracted from Barn Report and then further
processed to show three key factors in graphical form :
Max = Highest water used in one log interval as % of daily total
Min = Lowest water used in one log interval as % of daily total
MMR = Min and % of Max   Click here to view Document  Water Max Min Regression   Description: If the Water Max value tops out, it would suggest water supply is a limiting value.
IF WaterMin seems to relate to total volume, it suggests a significant number of pigs are
(and/or have to) drink out of hours to get enough.   Click here to view Document  Water Min Max and MMR   Description: Early analysis suggests that for typical situations Max is a constant. The daily volume
increases but the maximum is the same percentage of the total, so the pattern remains
approximately the same.   Click here to view Document  Water Shortage Incident   Description: Cost of this incident is likely to have been in excess of $5,000. Economic costs of such incidents is large and improved failure detection is strongly
recommended.   Click here to view Document  Water Supply Case Study   Description: This case study examines a US pig breeder farm with a site water meter. The data is

equipment performance would be worthwhile.   Click here to view Document  Water Use & Leakage at Sample Site 24 th Feb to 25 th June 2001   Description: Water leakage has been estimated using the lowest value recorded on any particular day (the

throughout the relevant 24 hour period, as illustrated in the following chart section.   Click here to view Document  Water Zero Level : Special Cases   Description: In my view, this indicates competition for resources.
The non zero min level falls off at just the point where pig numbers are starting to drop as
some pigs are sold out of the building, and where feed intake has flattened off. At higher
weights, water intake as related to feed intake (Feed : Water ratio) goes down.   Click here to view Document  Wind Power Polar Diagram   Description: In this example, wind came almost entirely from the West - mainly from the North West and

are you to believe? Are they all as good as one another?
They are not all the same. You know this already, but you don't know how much difference it
really makes to your bottom line. Is that $2 less a drinker a good buy or not? Does it wear out
quicker, does it leak more? Is more expensive always better? No one is going to tell you.
