Maternal metabolic demands caused by pregnancy and lactation: association with productivity and offspring phenotype in high-yielding dairy ewes
(2019)
Pregnancy and lactation, especially when concurrent, create a rather metabolically demanding situation in dairy ruminants, but little is known about their e ects on o spring phenotype and milk yield. Here, we evaluated the ...
Observational study on a novel management system involving 10 lambings per year in one high-yield dairy ewe farm
(WBC 2018 SPONSORS, 2018)
Objectives: In order to reduce non-productive days in dairy
