【Abstract】 In this experiment,96 male AA broilers were randomly divided into equal 4 groups with 4 replicates of 6 broliers per group.And the dietaryelectrolyte balance were 0,120,240,360 mmol/kgeach group raised in normal methods and immunity.Weights in 21 and 42 days showed the general performances ofDEB240 are better than the other groups in heat stress.42 to44 days were prepared for urgent heat stress in climate controlled house.The temperature sequence for heat stress was 24 to 32℃ in 30 min,32 to 36℃ in 30 min,36 to 37℃ in 15 min,37 to 42℃ i n 45 min.Then we measured the blood biochemical and physiological indexes at 42℃ .The results showed the DEB 240 could effectively keep the acid. base balance,the ion indexes changed little and it took broilers more time to pant and prostrate.It was concluded from the above indexes that the diet with DEB240 was better than others in heat stress.更多还原
