Lesson 1Dung handling and water flow: paths, channels, scraping, collection spots and safe store placeThis part details dung paths, channels, and scraping ways for small barns. It explains collection spots, gravity flow, and placing stores to guard water, cut smells, and allow growth later.
Alley slopes and gutter cross-section designManual versus mechanical scraping routinesTransfer channels, pits, and pump locationsLocating storage away from wells and homesRunoff control and access for emptyingLesson 2Sizing and space planning: cow count, space per cow, stall or free area sumsThis part shows sizing a 20-cow barn, summing stall or free space, and setting space per cow. It links cow ease, dung paths, and feed space to daily work and herd growth.
