Low birth weight puppies present an increased risk of neonatal mortality, morbidity, and some long-term health issues. Yet it has not been investigated if those alterations could be linked to the gut microbiota composition and evolution. 57 puppies were weighed at birth and rectal swabs were performed at 7 time points from birth to 56 days of age....

La gestion de la reproduction en élevage peut faire apparaître deux situations très différentes : dans certains cas, l'objectif est de prévenir l'apparition des chaleurs et donc d'inhiber le déclenchement de l’œstrus, alors que dans d'autres, il s'agit de déclencher l'apparition des chaleurs en vue par exemple de planifier la reproduction. Plusieur...

Colostrum may be deleterious to the kitten, or the production may be insufficient in some situations. A substitute for colostrum is then necessary. The advantages and the disadvantages of the different possible alternatives are analysed in order to provide the best chances of survival to the newborn.
Article
Full-text available
Colostrum provides a crucial supply of immunoglobulins (Ig), energy and growth factors. Passive immunity is mainly due to massive absorption of colostral Ig, via two mechanisms, in the kitten. The quality of the transfer can be evaluated indirectly by measuring the serum alkaline phosphatase concentration. In this species, the energy content of col...
Presentation
La morbidité et la mortalité néonatales chez les chiots et les chatons sont élevées. Les problèmes le plus souvent observés sont l'hy-poxie, l'hypothermie, l'hypoglycémie, la dés-hydratation, la perte de poids. Les vétérinaires sont souvent confrontés aux pathologies néo-natales et la connaissance des normes physio-logiques est essentiel pour dépis...
Presentation
Des données récentes chez les chiots et chez les chatons montrent que la mortalité entre la naissance et l'âge de deux mois est en moyenne entre 13,4 % et 16 % en France. La mortinatalité représente plus de la moitié de la mortalité totale. Cette mortalité à la nais-sance peut être expliquée en partie par une hypoxie lors de la mise-mas. Les chiots...
