The present study was conducted to evaluate the effects of broiler breeder diet with lower energy density on growth performance, carcass and meat quality of their offspring. One hundred and twenty Lean line female broiler breeders were assigned to two different dietary treatments with 60 birds each. The study commenced at the beginning of the laying period, defined as the age when total egg production reached 5% of the flock. Breeders were fed normal energy density diet (ND, 11.72 MJ/kg of ME) and 20% low energy density diet (LD, 9.40 MJ/kg of ME), respectively. All of their offspring were given the same diet. The experiment period of offspring lasted for 56 days. The results showed that no significant difference was found in 1-day-old chicken body weight, daily gain and F/G (P>0.05), there was a decreasing trend of 1-day-old chicken live weight in LD group. The fat and protein contents of breast and thigh muscle of LD group were slightly higher than those of ND group (P>0.05). The offspring of broiler breeders fed LD had higher thigh muscle percentage than those fed ND (P<0.05). pH, L*, a* and b* values, drip loss and cook loss of breast and thigh meat of their offspring had no significant difference between two groups (P>0.05), there were increasing trends of pH, a* and b* values and decreasing trends of drip loss and cook loss in LD group. However, breeders from LD group decreased shear force and diameter of breast and thigh muscle and increased density of breast and thigh muscle fiber of their offspring (P<0.05). In conclusion, the results suggested that 20% low energy diet of the Lean line broiler breeders had impact on carcass composition and meat quality of breast and thigh of their offspring.
