Feeding the pregnant sow Ray King, Program Manager, Pork CRC
3
The optimum level of feeding in pregnancy varies because of such factors as: size and body condition of sow environment housing health level of productivity
4
Live weight The sow requires an extra 2.9 MJ DE/day (or about 0.2 kg feed/day) for an increase of 30 kg in body weight
5
For 30 kg maternal gain in pregnancy
6
Environment The sow requires an extra 6 MJ DE/day (or about 0.45 kg/d) for each 5ºC below the lower critical temperature
7
Housing The sow kept in individual stalls may require an extra 2.5 MJ DE/day (or about 0.2 kg/d) because their activity is greater and, consequently, their energy requirement for maintenance is greater than that for group housed sows. In addition, the individually housed sow usually has a higher Lower Critical Temperature than sows kept in groups.
8
Health If the disease burden in the herd is high, pregnant sows may require up to 0.5 kg feed/day to cover the extra energy requirements for maintenance
9
Feed intake in pregnancy Feed levels need to be adjusted depending upon temperature, housing, sow size, health status. Protein levels are usually adequate with minimum of 13% crude protein and 0.5% lysine. No simple recipe for determining feed level for sows during pregnancy.
