Abstract:

The experiment was aimed to study the effect of organic selenium and vitamin E (VE) on meat quality trait,blood biochemical indexes and antioxidant indexes of broiler chicken. 280 1-day-old AA broiler chicken were chosen and assigned to 7 groups with 40 broiler chicken per group. Group 1 was control group that did not adding organic selenium and VE,groups 2-7 were added with 100 IU/kg VE,0.15 mg/kg organic selenium and 100 IU/kg VE,0.30 mg/kg organic selenium and 100 IU/kg VE,200 IU/kg VE,0.15 mg/kg organic selenium and 200 IU/kg VE,0.30 mg/kg organic selenium and 200 IU/kg VE,respectively. The results showed that the organic selenium and VE had significant effects on eviscerated rate,slaughter rate and chest muscle rate (P< 0.05),while no significant effect was found on semi-eviscerated rate and leg muscle rate(P> 0.05). Adding 0.15 mg/kg organic selenium and 100 IU/kg VE could reduce drip loss,cooking loss,L* and pH,and there were extremely significant difference or significant difference of cooking loss and L* compared with control group (P< 0.01;P< 0.05),while this made little effect on a*,b* and shear force (P> 0.05). It could significantly or extremely significantly reduce the CHO and MAD contents (P< 0.05;P< 0.01),increase the content of GLU,T-AOC and GSH-Px,and there were extremely significant or significant differences of GLU and GSH-Px compared with control group (P< 0.01;P< 0.05).But there was no significant difference of HDL-C,LDL-C,CAT and SOD contents among all groups (P> 0.05).
