Phenotypic relationships between maternal energy metabolism and lamb body weight development during lactation for pure- and crossbred sheep populations in low and high input production systems

Abstract There is an increasing economic pressure in sheep production. Hence, it is imperative to use all available tools contributing to improvements in lamb survival. In this regard, there is a lack of studies addressing the impact of maternal body condition traits on lamb performances during lactation. Specifically, the focus of the present study was to analyse associations between ewe traits reflecting maternal energy metabolism and lamb body weight (LBW), separately in a low and in a high input production system. The dataset considered 199 Merinoland- (ML) and 45 Rhonsheep (RH) ewes from the high input production system (> 33% concentrates in the ration), as well as 47 Coburger Fuchssheep (CF), 78 RH and eight crossbred (CB) ewes from the low input production system ( 100 kg EBW were 1.41 kg heavier at weaning than lambs from ML ewes  3 mm had significantly greater 12 W W (2.63 kg, P
