Analyser et comprendre l'impact des foins ventilés sur la production laitière caprine

Abstract : The use of ventilated hay in goat farming raises many questions about its value and its impact on milk production. Based on the observations of breeders on the loss of milk quantity and on the fat levels, a first work had highlighted a defect in physical fibrosis. This hypothesis rejected, a new study questions the impact of ration balance using ventilated hay. 32 forage and 15 peak of lactation rations were thus studied, thanks to CapAlim© software. Beyond a disappointing quality on hay mainly multi-specie grasslands, a waste of nitrogen and energy is often put forward. A lower milk production, with 73% milk produced compared to the possibilities given by the feed used is also observed. 2 groups of breeders appear to have problems with rations and defects on their feeding practices. They do not produce enough milk and waste their nutritional resources. One group is able to make more milk than the ration allows and uses correct dietary practices, although their peak lactation is low. This study confirms the interest of works to support and sensitize breeders, which are realized by the REDCap especially on the feed component and grassland management. The track of a defect in chemical fibrosity needs to be explored.
