对两种脱水餐厨垃圾（DFW）产品作为育肥猪的潜在饲料进行了评价。对于每种产品，新鲜的食品废物，获得了在佛罗里达中部的度假胜地复杂的食品服务业务。垃圾主要是吃剩的食物和盘子的碎屑。将废物切碎，与原料（大豆壳和小麦粉[DFW 1]或大豆壳和磨碎的玉米[DFW 2]）混合，造粒并干燥。然后将干燥的产品与额外的切碎的新鲜食物废物混合并干燥;然后重复该过程。最终的DFW产品含有约60%的干燥食品废物。DFW 1和DFW 2产品含有11.4%和8.4%的水分、15.0%和14.4%的CP、13.8%和16.0%的粗脂肪、10.4%和14.5%的粗纤维、5.8%和4.7%的灰分、0.63%和0.64%的赖氨酸、0.54%和0.63%的Ca、0.34%和0.38%的P、0.69%和0.86%的Cl，分别为0.35和0.47%Na。分别对48头和72头育肥猪（56 - 112 kg）进行了两项饲养试验，比较了试验1中不含（对照）或含40% DFW产品（DFW 1）和试验2中含40或80% DFW产品（DFW 2）的日粮。两个试验中饲喂DFW日粮的猪的ADG相似（P> 0.05）。10)和平均增重：饲料比优于（P = 0.06，试验1; P <0.01;线性，试验2）对照猪。胴体瘦肉含量和瘦肉品质评分没有降低（P>. 10)通过在任一试验中给猪饲喂DFW饮食。在试验2中，随着饮食中DFW 2量的增加，胴体脂肪变得更软（P <0.01;线性）。因此，脱水的餐馆食物废物有可能为猪生产营养饲料，同时提供可行的固体废物处理选择。
Two dehydrated restaurant food waste (DFW) products were evaluated as potential feedstuffs for finishing pigs. For each product, fresh food wastes were obtained from food service operations at a resort complex in central Florida. The wastes were mostly leftover food and plate scrapings. The wastes were minced, blended with a feed stock (soy hulls and wheat flour [DFW1] or soy hulls and ground corn [DFW2]), pelleted, and dried. The dried product was then blended with additional minced fresh food wastes and dried; this process was then repeated. The final DFW products contained approximately 60% dried food wastes. The DFW1 and DFW2 products contained 11.4 and 8.4% moisture, 15.0 and 14.4% CP, 13.8 and 16.0% crude fat, 10.4 and 14.5% crude fiber, 5.8 and 4.7% ash, .63 and .64% lysine, .54 and .63% Ca, .34 and .38% P, .69 and .86% Cl, and .35 and .47% Na, respectively. Two feeding trials with 48 and 72 finishing pigs (56 to 112 kg), respectively, were conducted comparing diets without (control) or with the DFW product included at 40% of the diet (DFW1) for Trial 1 and 40 or 80% of the diet (DFW2) for Trial 2. Pigs fed the DFW diets in both trials had ADG that were similar (P > . 10) to and average gain:feed ratios that were superior (P = .06, Trial 1; P < .01; linear, Trial 2) to those for control pigs. Carcass lean content and lean quality scores were not reduced (P > . 10) by feeding pigs the DFW diets in either trial. Carcass fat became softer (P < .01; linear) with increasing amount of DFW2 in the diet in Trial 2. Thus, dehydrated restaurant food wastes have the potential to produce a nutritious feedstuff for pigs while offering a viable solid waste disposal option.
