Effect of vitamin E and selenium composition, vitamin B complex and multi vitamin electrolyte on suddenly death syndrome in broiler chickens

The aim of this study is the effect of vitamin E and selenium composition, B complex and multi vitamin electrolyte in sudden death syndromes of broilers. One hundred and twenty eight 1-d-old Ross 308 broiler chickens were randomly assigned in 4 treatments, each group including 8 chickens. The first group treated with no vitamin, the second group treated with vitamin B complex, the third group treated with the composition of vitamin E and selenium, and the forth group treated with multi vitamin electrolyte. In the period from 0 to 42 day, the mortality due to SDS in all groups was recorded. The carcass related to SDS examined according to physical changes. After 30 minutes of death and in end of period, blood samples were taken and blood factors such as NA, K, and Mg were measured. In the first group the mortality were 4 and the level of the serum was significantly different comparing to the group with B complex, multi vitamin electrolyte and vitamin E and selenium composition(p<0.05). Regarding the results of the study using the vitamin E and selenium, B complex and multi vitamin electrolyte are significantly effective in prevention and control of sudden death syndromes of broilers
