The Tinholt nursery farm uses a two tank liquid feeding system with one low and one high protein diet. The diet starts as high protein and gradually switches to low protein. Growth performance is usually decreased during the first two weeks of nursery, and then increases rapidly to above dry feed levels. The use of co-products in the feed means feed costs are lower than a dry diet, and the diet also helps gut health in the pigs. The down sides of the system are the high initial and operating costs, reduced initial feed intake, high levels of management needed, risk of yeast or bacteria growth, and inconsistency in co-products.
