Yes, pigs do eat water spinach. In Cambodia and throughout Southeast Asia, water spinach ( Ipomoea aquatica) is commonly used as pig feed, in addition to being a human food source. This is supported by numerous sources, including research studies on pig growth performance when fed water spinach http://www.lrrd.org/lrrd20/supplement/phin2.htm and https://pmc.ncbi.nlm.nih.gov/articles/PMC9967708/. It's considered a potential feed resource, especially in regions where protein-rich feed is scarce https://www.lrrd.cipav.org.co/lrrd17/7/chha17076.htm. Furthermore, discussions on forums about animal feed confirm its use for pigs and other livestock. https://www.backyardherds.com/threads/pond-plants-pigs-can-eat.41843/
While water spinach is suitable for pigs, it's important to note that the information provided pertains specifically to pigs and does not cover other animals, such as guinea pigs, where different dietary considerations apply. Several sources mention caution when feeding water spinach or similar leafy greens to guinea pigs due to their sensitive digestive systems. https://www.theguineapigforum.co.uk/threads/water-spinach-kangkong-for-guinea-pigs.176618/ https://www.guineapigcages.com/threads/water-spinach-a-species-of-morning-glory.117748/ https://www.guineapigcages.com/threads/ipomoea-aquatica-water-spinach.25442/
