Conjugated linolenic acid (CLna), conjugated linoleic acid (CLA), and other biohydrogenation intermediates in plasma and milk fat of cows fed raw or …
2007
International audience; Thirty lactating dairy cows were used in a 333 Latin-square design to investigate the effects of a raw or extruded blend of linseed and wheat bran (70:30) on plasma and milk fatty-acids (FA). Linseed diets, containing 16.6% linseed blend on a dry-matter basis, decreased milk yield and protein percentage. They decreased the proportions of FA with less than 18 carbons in plasma and milk and resulted in cis -9, cis -12, cis -15 18:3 proportions that were more than three and four times higher in plasma and milk, respectively, whereas cis -9, cis -12 18:2 proportions were decreased by 10–15%. The cis -9, trans -11, cis -15 18:3 isomer of conjugated linolenic acid was not …
Cis-15 intermediates of biohydrogenation in the duodenal flow of cows receiving linseed
2006
Duodenal samples from a previous experiment (Akraim et al., 2006) were reanalysed for determination of cis-15 intermediates of ruminal biohydrogenation (BH). Three dry Holstein cows fitted with a duodenal cannula received a diet with 14% (dry matter basis) raw linseed. C18 fatty acids (C18FA) represented 6.3% of dietary dry matter, and contained 57.8% of C18:3. After 18 days adaptation, on each cow, twelve samples of duodenal flow were taken over 3 days, composited, and analysed for FA composition. Cis-9,trans-11,cis-15C18:3 and trans-11,cis-15C18:2 (CLnA) were identified by GC-MS. The proportion of CLnA was low, in spite of the high C18:3 intake. The first step of C18:3 BH, isomerisation t…
Évaluation des risques liés aux pratiques de déballage mécanique des anciennes denrées alimentaires et valorisées en alimentation animale
2021
Le règlement (CE) n°68/2013 définit les anciennes denrées alimentaires (ADA) comme : « les denrées alimentaires autres que les déchets de cuisine et de table fabriquées à des fins de consommation humaine dans le plein respect de la législation de l’Union applicable aux denrées alimentaires mais qui ne sont plus destinées à la consommation humaine pour des raisons pratiques ou logistiques ou en raison de défauts de fabrication, d’emballage ou autres et dont l’utilisation en tant qu’aliments pour animaux n’entraîne aucun risque sanitaire ».Les coproduits (ex. les tourteaux oléagineux, les mélasses) n’ont pas été considérés dans cette analyse. Ils diffèrent des ADA par le fait qu’ils résultent…
