Abstract
White New-Zealand rabbits (24), aged 5 wk, were allocated into 2 groups and placed during 4 wk in an individual feed intake recording device. One group was fed a diet poor in S amino acids (0.43%), the other group was fed the same ration but supplemented with 0.2% DL-methionine. After 2 wk the treatments were reversed. During each period the rabbits receiving the methionine supplemented diet showed a higher growth rate and lower feed conversion ratio. No significant difference was observed either in the frequency of solid meal intake or the intake level or the feeding pattern during the 24 h cycle. These results are in contradiction, on some aspects, with those obtained previously with similar diets; the possible causes are discussed.
