However, I can respond to one of your questions, The one regarding water consumption of growing-finishing pigs to maximize feed intake. The total water needs will be affected greatly by the type of wate delivery system to the pigs depending if it is open trough, paddle waterers, nipple waterers, or combinations. Water requirements for swine vary depending on the season and the diet. Summer and winter will affect the amount consumed. Nipple waterers are typically used in nursery facilities and often in G-F facilities to provide continual access to fresh, clean water.
Several factors can influence the availability of water from thes types of drinkers.
