The last ten years have seen changes in weaning management, and an increase in weaning age and weight. The basic setup is important during weaning. The environment should be clean, dry, warm, and with proper height water drinkers before the piglets are moved in. Once the piglets are in the pen, the feeder should be opened to allow a small amount of food in, also mat feeding is useful to facilitate feeding. Observation is important part of weaning to make sure all piglets are drinking, and to encourage feed intake in those not developing feeding behaviour. Given the changing weights and age of weaning, this paper looked at the amino acid and alternate protein sources used in starter diets. In a three phase feeding system, reduced lysine caused no decrease in average daily gain, but feed efficiency was reduced. In phase three the average daily gain was reduced with a low lysine diet. This indicates there could be a cost savings by reducing lysine in the first two phases, but lysine should not be reduced in the third phase. Lastly, replacing fish meal in starter diets was tested. It was found crystalline amino acids or intestinal peptide protein can be substituted, and these alternative protein sources are unnecessary in phase 3 diets.
