1 Average (minimum, maximum) are provided. 2 Average daily gain. 3 Dry matter intake. 4 Adjusted feed-to-gain ratio (F:G) accounts for differences in animal age and size during tests. The values are the base F:G values multiplied by the trial group’s metabolic mid-weight divided by the individual’s metabolic mid-weight.
