Effect of energy intake by narrow pen reared sows during lactation on sow and litter performance



Effect of energy intake by narrow pen reared sows during lactation on sow and litter performance



Journal of Taiwan Livestock Research 20(2): 17-25



Forty-two Landrace sows reared in narrow pens were used to examine the effects of energy intakes during a 4-week lactation on performance of sows and litters. Diets contained metabolizable energy 10.3, 11.2 or 12.2 Mcal/sow daily for parity 1 and 2 (Experiment 1); and 11.3, 12.2 and 13.2 Mcal/sow daily for parity 3 (Experiment 2). In Experiment 1, sows given diets with lower energy contents had increased net lactation weight loss and backfat loss.
