1 Feeding of Pigs Linda Fager Landbrugsskolen Sjælland

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

3

4 sows 1500 – 1550 FU per year 50 % in the lactating 1 kg gain needs 3,2 FU If temperature fall 5º the sow nedds 0,25 FU ekstra per day

5 Skinny to fat Sows

6 Sows

7 Pregnant sow 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

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

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

10 Feeding young sows (polte) From 30 to 60 kgs: Mixture for growers are good enough Feed ad lib (but remember the condition and the legs) From 60 kgs to 90 kg: Mixture for lactating sows Max. 2,5 Fu/day Above 90 kgs: By condition (2-3 FU/day) The last two weeks before mating 3 – 4 FU/day (flushing)

11 Weaners 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)

12 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 days all pigs are given feed ad. libitum Weaners Gruel feed in a long trough

13 Growers 1 kg mix = 1,02 – 1,08 FU 210 FU per pig ( kg) Ad lib / restrictive feeding (from 65 kg) – Reduce fat – Reduce feed cost 1 kg meat 1,25 FE 1 kg fat 4 FE
