FeedingFeeding 1 FE = 1 FU (feed unit) New system from 2006:
1 Feso = 1 Feed unit for sows (= 7.700 kj)
1 Fesv = 1 Feed unit for all other pigs ( = 7.380 kj)
We have standards for– Amino acid– Mineral– Vitamins
The standards are based on trials
Raw material:Wheat, Barley and Soya meal

1 kg mix = 0,9 – 1,05 FU
Regulation– Feeling of satiety– High fibre content
Feed bye the eye– The sow need the right
condition

Lactating sowLactating sow
1 kg mix = 1,06 – 1,1 FU
High milk production No weight loos Feed the piglets
through the sow

Over 28 days she needs >180 FE.
Raise feed slowly over the first 10 days to 7-9 FE/day

6-9 kg: 1 kg mix = 1,2 – 1,3 FU
9-30 kg: 1 kg mix = 1,15 FU
46 FU per pig (7-30 kg)

Feeding after weaning
Do not restrict feed in the first 3 days.(If no problems with diarrhoea)
After day 4 you can feed restricted if needed:
Everybody eats at the same time (min. 12 cm/pig at the trough)
Give feed 2-4 times pr. day
The feed must be eatet in 5-30 min. (through must be clean)
The smallest 10% - 20% of the pigs can be given at better feed.
In the first week after weaning feed intake is a very important factor in reducing diarré.
After 10-12 days all pigs are given feed ad. libitum

Gruel feed in a long trough

kg) Ad lib / restrictive
feeding (from 65 kg)– Reduce fat– Reduce feed cost
• 1 kg meat 1,25 FE
• 1 kg fat 4 FE
