Beziehungen zwischen Futteraufnahme, Seitenspeckdicke und ausgewählten Merkmalen der Aufzuchtleistung laktierender Sauen

Abstract. Title of the paper: Relationship between feed intake, side fat thickness and special parameters of rearing Performance of lactating sows
A total of 106 Camborough sows were used to study the relationship between feed intake, side fat thickness at the end of pregnancy, their change during lactation and special parameters of rearing Performance. Sows with a high side fat thickness at the end of pregnancy realised a lower feed intake during lactation (r = −0.206*) but a higher loss of side fat thickness (r = −0.499**) than sows with worse body condition. High feed intake during lactation stimulates a high number of weaned piglets (r = 0.299*) and the weight of weaned litter (r = 0.321*). The amount of feed intake in first week of lactation is most important for it.

Generally, sows with a high predisposition for mobilisation of body fat and high intake of food during lactation realised the significant highest rearing Performance (r = 0.436***).
