The present study aimed to evaluate the effect of using three types of locally produced probiotics as an early feeding of broiler chicks in hatcher on body length, breast circumambient, thigh, body and breast fleshing and bone lenghts of broiler.

The different types of local probiotics as following: First probiotic product contains locally isolated bifid bacterium from cecum of healthy adult chickens, the second probiotic product contains standard human source isolation of Bifi.

longum BB536, the third probiotic product contains mixture of first and second probiotic with ratio 1 : 1.

A total of 300 one day old non-sexed chicks of Ross308 were randomly distributed on five treatments at chicks transport boxes in hatcher, each treatment consists of 60 birds with 3 replicates (20 birds each) , the treatment were as follows : T1 (Negative control) chicks without any offered until arrived farm, T2 (Positive control) chicks were offered standard feed in hatcher by spray and sticked as paste in transport boxes sides, T3 chicks were offered on first probiotic in hatcher by spray sticked as paste in transport boxes sides, T4 chicks were offered on second probiotic in hatcher by spray and sticked as paste in transport boxes sides and T5 chicks were offered on third probiotic in hatcher by spray and sticked as paste in transport boxes sides: The result showed significant increase (P < 0.05) in (T3andT5) than T1 in regarding the circumference of thigh, lengths of thigh bones drumstick and body filling degree, also improved in body length, circumambient of breast and body fleshing.

It concluded that chiks were using three kinds of probiotics as an early feeding in hatcher improved carcass traits and body dimensions in broilers.
