Pork production in Ecuador is of significant economic and nutritional importance. Many of these operations are family- or backyard-based and utilize alternative feed ingredients to reduce production costs. The current study aimed to determine the chemical composition of cooked cassava and taro, and to evaluate their inclusion in the feed of backyard pigs during the growth and fattening phases. A total of 42 castrated pigs from two geographic locations in Ecuador were studied over a period of 100 days, during which their weight and measurements were recorded at three-week intervals. At the end of the experiment, ileum samples were collected from the slaughtered pigs in order to calculate the apparent digestibility of the feed. The crude protein levels of cassava and taro were found to be 3.2% and 2.1%, respectively. The combination of cooked cassava and taro was found to be a suitable replacement for corn, with the best results observed in the group receiving a diet incorporating 21% each of cassava and taro. Analysis of the ileal content also revealed that this group exhibited the highest nitrogen assimilation from the diet.
厄瓜多尔的猪肉生产具有重要的经济和营养意义。这些生产活动大多以家庭或后院养殖为主，并使用替代饲料成分以降低生产成本。本研究旨在确定煮熟的木薯和芋头的化学成分，并评估它们在育肥猪生长育肥阶段饲料中的添加效果。研究对来自厄瓜多尔两个地理位置的42头去势公猪进行了为期100天的观察，期间每隔三周记录它们的体重和体尺数据。实验结束时，采集屠宰猪的回肠样本以计算饲料的表观消化率。结果发现，木薯和芋头的粗蛋白含量分别为3.2%和2.1%。研究发现，煮熟的木薯和芋头组合是玉米的合适替代品，在木薯和芋头各占21%的日粮组中观察到了最佳效果。回肠内容物分析还表明，该组从日粮中吸收的氮最多。
