摘要

North Carolina laws regulating poultry litter (PL) land application require that PL be applied based on crop need and PL nitrogen content with monitoring of soil P, Cu, and Zn. Even with efforts to decrease fecal nutrient excretion, there is also a need to extend the useful life of current bedding materials and to develop alternative uses of spent PL. Current systems developed by Resource Enhancement Technologies, Inc., to heat treat PL may extend bedding life and offer alternative uses of PL. This process has several potential advantages: 1) PL can be treated and re-used on the farm, 2) a product can be produced which does not have to be land applied, and 3) a product can be produced that can be moved out of the area where it is produced. The objective of this study was to determine if heat processed turkey litter (TL) can be reused as bedding for turkeys. Pine shavings (PS) which had been used as bedding to rear Large White male turkeys from hatch to 20 wks was processed at 204°and 427°C in an enclosed system. Four litter treatments (LT) were used: 1) control - new PS (T1), 2) TL processed at 204°C (T2), 3) a 70:30 (w/w) mixture of TL processed at 204°or 427°C (T3), and 4) a 95:5 (w/w) mixture of TL processed at 204°or 427°C (T4). These LT were placed in 36 floor pens in a randomized block design to provide 9 replicate pens per LT. Thirty Large White turkey hen poults were placed in each pen on day of hatch. The birds were reared to 10 wks. Mortality and feed consumption were monitored. Birds were weighed at 6 and 10 weeks of age. Period and cumulative feed conversion (FC) ratios were calculated. Regression analysis of SAS, Inc. was used for data analysis. LS Means procedure was used to separate treatment means (P≤0.05). At placement, T1 hen poults (60 g) were heavier than T2, T3 or T4 (59 g) hen poults. At 6 wks, T3 hens were heavier than Tl (1.78 kg), T2 (1.80 kg) or T4 (1.81 kg) hens. At 10 wks, there were no differences in BW (5.42 kg) among treatments. There were no differences for 6 wk (1.44) 10 wk (1.78) or 6 to 10 wk (1.95) FC. LT did not affect mortality. Litter treated by the process used for this study produces a bedding material suitable for rearing market turkeys.
