Vergleichende Studie uber die Abgangsursache von Saugferkeln in der Freiland- und Stallhaltung der ZuchtsauenInfluence of indoor and outdoor production on preweaning mortality of piglets

摘要

Preweaning piglet mortality was evaluated in 21 pig production units (11 indoor, 11 234 litters; 10 outdoor herd, 9 861 litters) during a period of five years. Preweaning death was significantly (P<0.05) higher in the outdoor, cornpared to the indoor production. Overlay deaths and losses caused by injuries were significantly higher (P<0.001), low viability, starvation, death due to low birth weights, cold stress, wasting and scours significantly higher (P<0.05) in outdoor compared to the indoor production. In East European outdoor units, higher preweaning piglet losses must be taken into consideration.
