The effects of two feed restriction programs with and without probiotic on performance, egg traits and production cost in Laying Japanese Quails

This experiment was carried out to evaluate the effect of two feed restriction program with and without probiotic on performance and egg traits of Japanese laying Quails. In the current study 216 quails were used from 6 to 14 weeks in 6 Treatments, 3 Replicates and 12 Quails in each replicate as a (3*2) include 3 diets (diet as NRC 1994 nutrient recommendation), diet with 7 hours feeding and 1 hour feed withdrawal and diet with 5% low nutrients than NRC 1994 nutrient recommendation and two levels of protexin probiotic in a completely randomized design. The results showed that time feed restriction caused the egg weight increased (P
