摘要

Finding a reliable source of shavings for broiler bedding at an acceptable cost is often difficult. LitterPlus~(~R) (LP) is a bedding material produced from recycled wood pallets through patented grinding and processing systems. The objective of this study was to compare pine shavings and LP for use as broiler bedding material. Two broiler trials were conducted. In the first trial, male broilers were grown in litter floor pens with either 2 or 5 cm of either pine shavings (PS) or LP. There were 32 pens (50 birds per pen) with 8 replicate pens per treatment. All birds were fed the same feeding program: starter from 0-3 wk, grower from 3 to 6 wk and finisher from 6 to 7 wk. Feed consumption and body weights (BW) were measured by pen at 3 and 7 wk. Mean BW and feed conversion (FC) were calculated. A sample of birds (n=10) from each pen was evaluated for hock (HI) and foot pad (FP) condition and breast blister index (BI). Each pen was evaluated at the end of the trial for cake index (CI). At the completion of trial 1, all litter was removed from each pen and stored separately by type (PS & LP) until the next trial. In trial 2, each supply of stored litter was placed into 18 pens (36 total pens). The stored litter was then "top dressed" with new material. Male broilers were placed in each pen (50 birds per pen) and reared to 7 wk of age as in trial 1. There were two treatments in trial 2; PS and LP, with 18 replicate pens per treatment. Data were collected as in trial 1. Ammonia (NH3) levels were determined in each pen at the end of each trial. All data were analyzed using the General Linear Models program of SAS (SAS, 1992). In trial 1, the effects of litter depth and type and the interaction on BW, FC, CI, HI, FP, BI, and NH3 were determined. In trial 2, the effect of litter type was determined on these same measurements. Means were separated using least significant difference (P≤0.05). In trial 1, birds reared on 2 cm of bedding had higher (more discoloration) HI than those reared on 5 cm of bedding. Pens with LP had a higher CI (more caked litter) than those with PS at the end of trial 1. There were no other differences in bird performance or litter evaluation for trials 1 or 2. In conclusion, broilers reared on LitterPlus~(~R) perform as well as those reared on pine shavings.
