ABSTRACT
The current study was conducted at a commercial parent stock farm to check the effect of different diet dilutions on growth and production performance of broiler breeders. A total of 6,400 parent stock female birds (Ross 308 strain) were randomly selected at the age of day-old-chick as per capacity of a poultry house. Birds were distributed in 16 replicates (4 replicates per treatment) following completely randomized design for applying 4 dietary treatments namely control diet (CON) or 0% dilution (2800ME+14%CP); less diluted diet (LES) or 5% dilution (2660ME+13%CP); medium diluted diet (MED) or 10% dilution (2520 ME+12% CP); extra diluted diet (EXT) or 15% dilution (2380ME+11%CP). Each replicate was allocated 400 birds randomly. Birds were offered (diluted) grower diet from 4 to 19 weeks. The impact of said treatments were checked through growth and production parameters along with economic appraisal of diet formulation. The findings revealed that MED diet produced maximum body weight uniformity, peak egg production and total eggs per hen-housed, while poor performance was observed in EXT treatment. The CON and LES treatments produced comparable results. Although diluted diets were comparatively economical than CON commercial diet, however more feed scale was offered to birds in diluted treatments which neutralized the benefits of low cost diluted diets. To sum up, 10% dilution is viable in commercial rearing while less than 10% dilution produce non-significant results. Furthermore, it is difficult to balance nutrients for higher than 10% diet dilution which produce some unwanted side effects regarding growth and egg production.
