In the 1st experiment, five sources of agro industrial by products (date stone, sugar beet pulp, orange pulp, lemon pulp and olive cake) were evaluated at two levels (35 and 70%) of the control diet barley or (9.5% and 19%) of the total diet. Accordingly, a total of 11 experimental treatments were tested. In 2nd experiment, the best two by products (sugar beet pulp and orange pulp), selected from 1st experiment, at the two levels (35% or 70%) of the control diet barley were tested without or with two feed additives probiotic (300g / ton diet) and citric acid 20 kg / ton UR - http://172.23.153.220/th.pdf ER -
