Lesson 1Manure handling and drainage: alleys, gutters, scraping, collection points and safe storage locationThis section details manure alleys, gutters, and scraping patterns for small barns. It explains collection points, gravity flow options, and siting storage to protect water, reduce odour, and allow future expansion.
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 spatial planning: cow numbers, stocking density, stall or loose housing space calculationsThis section explains how to size a 20-cow barn, calculate stall or loose housing space, and set stocking density. It links cow comfort, manure alleys, and feed space to daily routines and future herd growth.
Determining herd size and growth assumptionsCalculating stall dimensions and alley widthsLoose housing space per cow and group pensStocking density targets for small herdsLayout examples for 20-cow barn footprintsLesson 3Worker safety and ergonomic design: safe circulation, non-slip surfaces, lighting, handling gates and animal restraint basicsThis section addresses worker safety and ergonomic design in small barns. It covers safe circulation, non-slip walking surfaces, lighting, and simple handling gates and restraint points that reduce strain and injury risk.
Safe worker paths and cow–human separationNon-slip walkways, steps, and thresholdsLighting levels for milking and night checksErgonomic placement of tools and outletsHandling gates and basic restraint pointsLesson 4Barn orientation and placement: sun path, prevailing wind, distance from house and manure area, access routesThis section explains how to place a small dairy barn on the farmstead. It considers sun path, prevailing winds, distance from the house and manure storage, and access routes for feed, milk pickup, and emergency vehicles.
Using sun path to warm or shade barn areasOrienting to prevailing winds for ventilationDistances to house, wells, and property linesAccess routes for feed, milk, and service trucksFuture expansion space and biosecurity zonesLesson 5Milking area options for small herds: parlor-less hand or bucket milking, mobile or fixed parlours, milking alley planningThis section compares milking options for small herds, from in-barn hand or bucket milking to simple parlours. It covers cow flow, hygiene, equipment placement, and planning milking alleys for safe, calm routines.

It addresses frost protection, drainage slopes, and durable, non-slip finishes for cow safety.

It covers feeding alleys, resting areas, bunk and trough design, bedding choices, and drainage that keeps lying areas dry and reduces hoof problems.

It explains overhangs, gutters, downspouts, and simple ridge vents that protect walls, yards, and interior spaces.

It covers cross-ventilation, ridge vents, sidewall openings, and translucent panels to control heat, humidity, and interior light levels.

It explains spans, post spacing, bracing, and how to combine materials to reduce cost while keeping the building durable and easy to build.
