Effects of different sodium sources and levels on growth performance,serum biochemistry indices and meat quality of broilers
YUE Yuxiu;Jilin Engineering Vocational College;
This study was conducted to evaluate the different sodium sources and levels on growth performance,serum biochemistry indices and meat quality of broilers. A total of 1008 broilers aged 1 d were allotted to 9 groups with 4 replicates of 28 broilers. There are 3×3 factors,namely,three sodium sources(Nacl,NaHCO_3 and Na2 SO4),and three dietary sodium levels(2,1.5 and 1.0 g/kg). The trial last 126 d. Results showed that compared with the 1 g/kg sodium group,2 and 1.5 g/kg sodium groups had higher body weight at 126 d(P 0.05),and Nacl group had higher weight gain than NaHCO_3 and Na_2SO_4 groups at 1 ～ 28 d(P 0.05). Compared with the 2 g/kg sodium group,1 g/kg sodium group had higher contents of dry matter in fences at 112 d(P 0.05). Compared with the 1 g/kg sodium group,2 g/kg sodium group had higher serum levels of Mg,P,Na and Cl(P 0.05). Nacl group had higher serum level of K than the NaHCO_3 group(P 0.05),and lower contents of dry matter and viscosity(P 0.05)and lower ileum pH value(P 0.05),and higher dressing percentage(P 0.05). In conclusion,dietary included 1.0% sodium level can affect the feed efficiency of broilers at the early stage,and Nacl and NaHCO_3 can improve the feed grain ratio,while NaHCO_3 decreased the breast meat production.
