Abstract

Three experiments were conducted to determine the nutrient availability of extruded and fermented food waste (FW) and subsequent effects on growth performance of broilers. Dining hall food waste was either mixed with soybean meal (SBM) and extruded (CFW) or was fermented for 14 d to create a value-added product (FFW). One-day old male broilers (Ross 708 Byproduct Broiler, Sallisaw, OK) were used in 3 separate 21-d studies to determine AMEn (Exp. 1, n = 300) and apparent ileal digestibility (AID, Exp. 2, n = 240) of CFW and FFW, and their effects on growth performance (Exp. 3, n = 420). Treatments for Exp. 1 and 2 consisted of 1) CFW, 2) conventional SBM (CSBM), 3) extruded SBM (ESBM), 4) SBM + FFW (SFFW). A basal treatment was added to Exp. 1 as a control. Treatments for Exp. 3 consisted of 1) corn/SBM basal, 2) 10% CFW, 3) 30% CFW, 4) 1.5% FFW, 5) 5.5% FFW, 6) basal + commercial astaxanthin, and 7) basal + commercial antibiotic. There were 10 cages per treatment with 6 broilers per cage and balanced by body weight. Data were analyzed using the GLIMMIX procedure of SAS vs. 9.4 (Cary, NC). The ESBM had a greater (P < 0.01) AMEn content than CSBM and SFFW whereas CFW was intermediate. Broilers fed CFW and CSBM had increased (P < 0.05) AID of indispensable amino acids compared to SFFW, except Met whereas ESBM was increased (P < 0.05) compared to SFFW with the exception of His, Met, and Try. Broilers fed 1.5% FFW had increased (P < 0.01) feed intake (FI) and BWG compared to those fed the control basal diet. Broilers fed the commercial astaxanthin or 30% CFW had poorer (P < 0.01) FCR compared to those fed the basal control. In conclusion, 2 different forms of food waste successfully served as a nutrient source for broilers. Composite food waste and SFFW had similar AMEn to CSBM while CFW had a similar AID of amino acids to CSBM. Including 30% of CFW reduced FCR of broilers; however, including 5.5% of SFFW increased FI and BWG.

肉鸡热处理和发酵食物垃圾的氮校正表观代谢能（AMEn）、氨基酸（AA）的表观回肠消化率（AID）和生长性能12

我们进行了三项实验，以确定挤压和发酵食物垃圾（FW）的营养可用性及其对肉鸡生长性能的影响。食堂厨余与豆粕（SBM）混合后挤压成型（CFW）或发酵 14 天制成增值产品（FFW）。一天龄的雄性肉鸡（Ross 708 副产品肉鸡，Sallisaw, OK）被用于 3 项单独的 21 天研究，以确定 CFW 和 FFW 的 AMEn（试验 1，n = 300）和表观回肠消化率（AID，试验 2，n = 240）及其对生长性能的影响（试验 3，n = 420）。试验 1 和试验 2 的处理包括：1）CFW；2）传统 SBM（CSBM）；3）挤压 SBM（ESBM）；4）SBM + FFW（SFFW）。在实验 1 中添加了基础处理作为对照。实验 3 的处理包括：1）玉米/SBM 基础处理；2）10% CFW；3）30% CFW；4）1.5% FFW；5）5.5% FFW；6）基础处理 + 商业虾青素；7）基础处理 + 商业抗生素。每个处理有 10 个笼子，每个笼子有 6 只肉鸡，按体重平衡。数据使用 SAS vs. 9.4（北卡罗来纳州凯里）的 GLIMMIX 程序进行分析。与 CSBM 和 SFFW 相比，ESBM 的 AMEn 含量更高（P < 0.01），而 CFW 介于两者之间。与 SFFW 相比，饲喂 CFW 和 CSBM 的肉鸡不可缺少氨基酸的 AID 增加（P < 0.05），但 Met 除外；而与 SFFW 相比，饲喂 ESBM 的肉鸡不可缺少氨基酸的 AID 增加（P < 0.05），但 His、Met 和 Try 除外。与饲喂对照基础日粮的肉鸡相比，饲喂 1.5% FFW 的肉鸡采食量（FI）和体重（BWG）均有所增加（P < 0.01）。与饲喂基础日粮对照组的肉鸡相比，饲喂商品虾青素或30% CFW的肉鸡FCR较低（P < 0.01）。总之，两种不同形式的厨余可成功地作为肉鸡的营养源。复合食物垃圾和SFFW的AMEn与CSBM相似，而CFW的氨基酸AID与CSBM相似。添加 30% 的 CFW 会降低肉鸡的 FCR，而添加 5.5% 的 SFFW 则会提高 FI 和 BWG。
