In grazing dairy cows, the physiological undernutrition during early lactation due to increased demands for lactation and low dry matter intake is exacerbated by the need to get sufficient intake from pasture and the extra grazing energy costs. Undernutrition has profound impacts on reproduction by affecting multiple reproductive processes at different levels of the reproductive axis. The objective of this paper is to review the influence of undernutrition on reproductive events of the adult female ruminant, with emphasis on both grassland and mixed rain-fed grazing farming systems. The comparative endocrinology and reproductive biology among ewes, beef and dairy cows may provide a comprehensive knowledge of the metabolic and reproductive adaptation to feed restriction. Understanding the critical underlying physiological mechanisms by which nutrition affects reproduction is the base of focus feeding strategy to improve the reproductive performance of the female ruminant info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 0.985 2018 AGRICULTURE, DAIRY & ANIMAL SCIENCE 35 / 61 = 0.574 2018 Q3 T2 0.279 2018 Veterinary (miscellaneous) 2018 Q3 Animal Science and Zoology 2018 Q3 info:eu-repo/semantics/review info:eu-repo/semantics/publishedVersion de Brun, Victoria Carriquiry, Mariana Soca, Pablo (orcid)0000-0003-2907-0427 Sosa, Cecilia Universidad de Zaragoza Adrien, María de Lourdes Chilibroste, Pablo (orcid)0000-0003-2827-3054 Abecia, José Alfonso Universidad de Zaragoza 2008 700 Universidad de Zaragoza Dpto.
