The influence of dietary energy level on the response to betaine

The influence of dietary energy level on the response to betaine Young, M.G.; Tokach, Michael D.; Goodband, Robert D.; Nelssen, Jim L.; Dritz, Steven S. A total of 800 pigs were used to evaluate the influence of dietary energy level on the response to betaine in finishing pig diets. Dietary treatments were arranged in a 2 × 2 factorial with or without betaine and two energy density levels as the main effects. No betaine × energy interactions (P>0.05) were observed for the entire feeding period (51 to 210 lb) or for any of the three dietary phases. Pigs fed the high energy diets with added fat had (P<.05 greater adg lower adfi and improved f compared with pigs fed the low energy diets without added fat. adding betaine to diet had no influence on pig performance.>
