It is a management tool that aims to reduce transmission of infection from sow to piglets so piglets are weaned and isolated early (below three weeks). At this stage it is assumed that the maternal antibodies received by piglets are still high so it will be easy for them to fight off infection. Its principles are the foundation of the multi site production system that is gaining popularity in our country today.
Nutrition for these young pigs is very different from that weaned conventionally. Since they are younger and have more immature digestive system, their diet is simpler (not as complex) for better digestibility. The SEW diet is heavily fortified with synthetic amino acids and there is a need for a variety of protein sources. This is done to meet amino acid requirements and at the same time to improve the appetite of the piglets. Examples are: spray dried plasma, fish meal, dried whey, whey protein concentrate, spray-dried blood meal, soybean meal, and processes soy products.
Most farms, especially the old farms and with prevailing diseases opt to medicate their SEW feeds.
