Evaluation of leaves as a litter material

Department of Animal Science, North Carolina Agricultural and Technical State University, Greensboro 27411, USA.

The suitability of leaves for use as broiler litter was evaluated in four 49-d floor pen trials of 150 Avian x Avian female chickens each. In each trial, 25 broiler chicks were weighed and randomly assigned to one of six pens at a density of 1.2 m2 per bird. There were two replicates of each of the following three treatments: 1) pine wood shaving (control), 2) a mix of 50% pine wood shaving and 50% leaves, and 3) leaves. Litter materials had no significant (P > or = 0.05) influence on live weight, feed conversion, breast blisters, dressed carcass weight, carcass yield percentage, or mortality. Mortality of birds reared on leaves tended to be higher than the other treatments, but it was found to be nonsignificant at the P < 0.05 level. No significant differences were observed for percentage litter moisture among treatments. Body weight gain was significantly (P < or = 0.05) higher for the broilers reared on the leaf litter. Leaves alone or mixed with wood shavings have potential as an alternate litter material without compromising production or processing parameters at a low placement density.
