The Economic Analysis of Feeding Cull Sows to Heavier Weights

Authors: , , , ,


The objectives of this study were to estimate the amount of feed and associated costs of adding weight to cull sows, and, then to estimate the cost/benefit ratio of adding marketable weight to cull sows. As determined by last rib backfat, 8, 17, and 4 sows were classified into initial body condition scores of 1, 2, and 3, respectively. As sows’ BCS increased, the efficiency of adding weight decreases. Average daily gain (ADG) and Feed:Gain (F:G) was greatest in sows that began the trial as a BCS 1 and increased 1 condition score. Both traits declined during the remainder of the trial within all initial BCS.
