In mountain areas, hays are the main forage in winter diets for livestock. Barn-dried hays can be an alternative to traditional hays, which are generally characterized by a low feed value. The aim of this study was to compare the feed value of barn-dried hays with that of the fresh forage from a permanent meadow. The study was carried out over thre...
Valoriser la diversité végétale par la diversité animale : utiliser le foin de prairies remarquables pour alimenter les animaux de zoo
The effects of feeding system (indoor vs rangeland) and olive-cake (OC) supplementation (control vs supplemented) on fatty acid (FA) composition, lipid oxidation status and meat-colour stability were studied. Lambs were fed indoor with hay (OH) or reared on improved rangeland (RL). All lambs received concentrate at a rate of 400 g/head. day. Twenty...
A greater use of grass in the fodder and feed systems is a preponderant axis for the sustainability of the goat milk farms in front of economic constraints and societal expectations: increase of concentrate feed costs, strengthening of the fodder autonomy for cheeses with official quality label (PDO, Organic farming), animal welfare, environmental ...
The ingestion of 3 hay types by growing rabbits and the consequences on animal performance were studied in a first part. Two kinds of hay from high nature value grasslands [CFP (Colchico-Festucetum pratensis) and SBR (Senecioni-Brometum racemosi)] differentiated by their botanical composition were compared to a classical agricultural hay (control)....
Dans les 2 bases de données utilisées dans l’étude (prairies des Alpes et des Pyrénées), les relevés botaniques montrent que 30 à 50% des prairies sont dominées par les espèces non graminéennes. La typologie proposée pour les Diverses les plus fréquentes tient compte de deux traits qui influent sur leurs caractéristiques agronomiques : la hauteur d...

Face to climate, land and water use changes, sustainability of crop systems and quality of production is in debate. Long term database concerning hay's mineral contents, dry matter and climate dynamics (rainfall and temperature) have been collected and are used here to argue these questions. Such data are scarce, but here were made available, as th...
In a few years the new specifications of the Saint-Nectaire PDO cheese will prohibit the use of wet forage like grass silage, forcing number of producers to change their winter feeding. Therefore, Inra and the Saint-Nectaire inter-profession implemented an experiment to optimize milk production during a complete lactation with an 'all hay' winter d...
As an herbivorous animal, it is relevant to use plants or vegetable sources in rabbit rearing, and more particularly by vegetable products non concurrent of the human feeding. However most of the data on rabbit nutrition were obtained with pelleted feeds containing dehydrated and grinded raw materials. Therefore, it is necessary to implement our kn...
