Actualisation des recommandations alimentaires pour les chèvres laitières

Abstract: L’alimentation des chèvres laitières est un domaine en évolution technique rapide qui demande de plus en plus de recommandations alimentaires précises. La dernière mise à jour a été effectuée en 2007 et une actualisation s’avérait nécessaire. Les caractéristiques zootechniques de base (variations de la production de lait, des taux butyreux et protéique et du poids vif) sont mieux connues et désormais modélisées au sein du logiciel INRAtion. Les valeurs des besoins en énergie, protéines et minéraux au cours du … Show more

“…However, the calculated klm values were similar at 0.6 for M and S goats. Our results on energy efficiency were lower than those found by [18,41] (0.67 and 0.695, respectively). According to [29], under tropical conditions, ruminants are generally fed low-protein forages with high NDF content and low DM digestibility and ME concentration.…”

“…The numerically higher N digestibility in the S group is probably of little importance, if any, and it could be associated with lower feed and N intake in this group. According to [41], due to the mechanisms of N homeostasis, faecal and urinary nitrogen excretion are closely linked to N intake in ruminants. However, the similar urinary N observed in this experiment suggests that N was better converted into milk N in the M group.…”

“…In this study, Saanen goats with a single kidding produced less milk (1.55 liter/day) (P<0.05) than Saanen goats with twin kidding (1.90 liter/day) (Table 4). This observation has been done by other authors (Offoumon et al, 2023;Sauvant et al, 2012). Indeed, Offoumon et al (2023) reported for the same Saanen breed that goat having multiple kidding have an average daily milk production of 2.1 liter/day for twin kidding, 2.6 liter/day for triple kidding and 2.8 liter/day for quadruple kidding against 1.8 liter/day for a single kidding.…”

“…Chez la chèvre laitière différentes équations de prévision des rejets azotés urinaires ont aussi été proposées dans les dernières années (Sauvant et al 2012, Giger-Reverdin et Sauvant 2014. La même approche factorielle que pour les vaches a été appliquée aux données de la base « Caprinut », sachant que pour les deux espèces on a observé des réponses similaires de l'efficacité des PDI en protéines laitières ( Dans ce cas encore, la production de lait rentre de façon significative dans cette équation mais le gain de précision est très faible (ETR = 0,063).…”
