Effect of different levels of dietary sorbic acid on general performance and incidence of leg abnormalities of commercial broilers reared to roaster weight.

Two thousand male, day-old Hubbard chicks were housed in 20 pens (13.5 m2) to evaluate the effects on performance and leg abnormalities of feeding 0, 200, 400, and 600 g/ton dietary sorbic acid during the starter, grower, and finisher periods. These levels of dietary sorbic acid had no significant effect on live body weight, feed conversion, mortality, or the incidence of leg abnormalities of these chicken broilers reared to roaster weight.
