Increases in production management have led to sows producing larger litters, although there has been even greater increases in piglet mortality. This may be because a sow can’t create enough energy for its entire litter. This experiment sets out to find if altering the fatty acid ratio in sows will have an impact on fat mobilization in the body potentially effecting body condition and longevity of the sow. The experiment consisted of five diets specialized for farrowing and gestation, all with the same amount of fat but different omega-6:omega-3 ratios. The diets consisted of one control diet (tallow) three plant oil based ratios (10:1, 5:1, and 1:1) as well as a fish based oil ratio of 5:1. Piglet growth rate was measured and milk samples were taken. Piglets raised on the 5:1 plant diet had the highest birth weight and weaning weight while the fish oil had the lowest in both. Piglet growth rate and sow body weight were unaffected by diet. Altering the ratio in sow diets did not affect milk composition or output, suggesting that sows will compensate for changes in feed intake through body fat mobilization. Reducing the omega-6:omega-3 FA ratio below 5:1 put sows into a state of increased body fat mobilization, which may have negative impacts on body condition and longevity.
