Four variants of the low-protein, fat-enriched mash were formulated, differing in supplements of methionine, choline and vitamin B2 were compared with commercial mash for productive laying hens. The mash variants were tested in two group feed trials and four metabolic trials on hens of laying type Shaver Starcross 288. Feeding the fat-enriched mash of low-protein type fortified with methionine, choline and vitamin B2 supplement enabled to achieve, in comparison with commercial mash, adequate performance of hens of laying type and adequate table egg quality while shell percentage in egg weight was significantly higher. The significantly reduced content of crude protein in feed mash did not affect methionine intake and retention. It is not necessary to include high-quality proteins at amounts used until now in mashes of low-protein type.
