Impact of linoleic acid intake during lactation on the pigs born index. This variable represents the number of fully-formed pigs born per 100 weaned sows and was calculated by multiplying the subsequent farrowing rate (sows farrowed: weaned) and the number of pigs born in the subsequent cycle. Sows fed diets containing no added lipids consumed 84.4 ± 20.3 g/d of linoleic acid. Linear and non-linear (quadratic, cubic) models were compared using goodness-of-fit tests. Minimum Bayesian information criterion (BIC), minimum root mean square error (RMSE), and maximum coefficient of determination (R2) techniques were used to select the best-fit model. Means represented by bars without a common letter are different (P < 0.05)
