title: [Pathology among breeding does. Evolution of several plasma parameters among primiparous rabbit does].
abstract: One of the most important limiting factors of rabbit production is reproductive pathology. This pathology has two aspects: livestock reduction (elimination and death of rabbit does) and mortality of young rabbits before weaning. We studied alterations of hematocrit and of plasma Na, K, Ca, Mg, Pi, total proteins, prolactin, during gestation and lactation of primiparous rabbit does. In females which were going to die the first results showed a fall in plasma NaK, Ca concentrations and a rise in plasma Mg. We think that these alterations are only consequences of anterior metabolic alterations and are indicators or secondary causes of the animal's proximate death. We noticed a deep fall in plasma prolactin concentration before death; its signification is discussed. In the females which did not wean their whole litter, average prolacting levels during gestation and at the beginning of lactation were lower than in females weaning their whole litter. These first results would confirm the hypothesis that youngs' mortality is a pathology linked with dams' state.
