The birds in the first treatment were the control treatment, 4 and 6 kg of locally manufactured probiotic product per ton were given to the birds in the second and third treatment respectively. The eggs produced by the treatments were collected from hens at 53, 54, 56, 57, 59, 61, and 62 weeks with 10 days maximum period storage before entered the hatchery.
The results of 2173 eggs hatching revealed that adding probiotic significantly (p<0.01) increase fertility percentage, which leading to the significant (p<0.01) in accumulative chicks per hen per 98 days, also, significant (p<0.0001) increase in chick weight happened in the bird fed probiotic ration.
