4 The best practice of climate needs for pigs and how to fullfill it. By Carsten Bo Pedersen and Joergen Moeller Andersen Area sales managers Skov Asia Bangkok.
5 When we close the houses we take responsibility
6 Different behave for different age and size There are a lot of different ways to grow pigs. There is also a lot of different systems to keep the pigs in there houses.
7 Why ventilate? To control the climate High daily gain Low feed conversion rate (FCR) High state of health Low mortality Ensure right behaviour in the pen Ensure good air quality CO 2, NH 3, H 2 S, dust etc. Minimum ventilation m 3 /h
8 Why ventilate Temperature o C CO 2 Humidity Heat NH 3
9 Climate vs. ventilation ->Why worry about the climate? Heating CO 2 NH 3 Humidity Light Noise Temperature Dust Ventilation Climate
10 Animal Demands At more than 26C we will see a drop in production Aarnink et al, 2006
11 Remove excess heat
12 CO 2 CO 2 CO 2 CO 2 CO 2 CO 2 Max 3000 ppm CO 2
13 Sensitivity to climatic stress* *) Climatic stress: Temperature fluctuations High CO 2 High NH 3 Chill turing into draft Very sensitive Less sensitive
14 Behaviour - comfort Control of body temperature Build nests Slushing for cooling Resting behaviour Important indicator for the well being of the pigs
15 Behavior social relations Ranking Normal behavior Stress related Abnormal behavior
16 SKOV A/S in Glyngoere approx. 11,000 m2
17 SKOV a complete Company
18 R & D Development of systems Mechanical construction Development of hardware Development of software 56 employees 8-10% of turnover is spent on development and research Cooperation with universities and agricultural research centres

24 Different type of ventilation systems Low Power Ventilation (LPV) Combi Tunnel Tunnel
25 Climate date from Vietnam Hanoi and Ho Chi Minh
26 Local climate: Hanoi Local climate: MeteoNorm Climate database Access to climate data s from more than locations around the world. Hourly based information s on temperature, humidity etc. from every single location. Hanoi: Data s are collected over a number of years and statistically treated ( meaning no single day peaks from last summer ) Temperature profile
27 Calculation based on StaldVent with special Skov module Calculations : House and Production figures : Number and size of animal. Production form and batch length Temperature, humidity and CO 2 strategy How are the animals kept inside the house Size of house and insulation values Kind of ventilation and cooling system. Different calculations : Climate conditions in LPV mode Climate conditions in tunnel mode Heating requirements Effect of cooling Yearly electricity consumption.

33 LPV systems: DA 1200 and DA 1540
34 Tunnel ventilation pig houses Regulation of ceiling and wall inlets in smaller sections Emergency opening requires 24V Can operate max. 16 wall inlets of the type DA 1200 Designed for the harsh house environment Stands heavy cleaning Can be used together with all SKOV climate computers
