Abbreviation: CON, Basal diet (one diet, conventional feeding with coarse limestone); TRT1, S100 (same nutrition density of day total consumption with control group, but different ratio of nutrients and particle size of limestone with split feeding; morning time fine limestone / afternoon time coarse limestone); TRT2, S95 (95 % nutrient density of ME and SID amino acid, 90 % density in available phosphorus and calcium of day- total consumption compared with basal diet; morning time fine limestone / afternoon time coarse limestone).
