Abstract

One hundred and twenty-five boars were given diets containing five levels of methionine: 1·5, 1·7, 1·9, 2·1 and 2·3 g methionine per kg diet, from 21 to 49 days of age. The mean weight gain of the pigs given the diet containing 1·5 g methionine per kg was 71 g/day and this increased linearly to 346 g/day for the pigs given the diets containing 2·3 g methionine per kg.

From 49 to 97 days of age all pigs were given a commercial pig grower diet containing 160 g protein per kg. Live-weight gains over this period increased linearly from 477 to 689 g/day with increasing methionine content of the starter diets. There was no compensatory weight gain.
