Résumé
We appreciate the opportunity to respond to the Letter to the Editor by Rastani and Kertz, 2008Rastani R.R. Kertz A.F. Letter to the Editor: Differences in forage to concentrate ratios can confound results: A comment on Petit et al. (2007).J. Dairy Sci. 2008; 91: 2533Abstract Full Text Full Text PDF PubMed Scopus (1) Google Scholar in response to our paper published in the Journal of Dairy Science (Petit et al., 2007Petit H.V. Palin M.F. Doepel L. Hepatic lipid metabolism in transition dairy cows fed flaxseed.J. Dairy Sci. 2007; 90: 4780-4792Abstract Full Text Full Text PDF PubMed Scopus (65) Google Scholar). We acknowledge the fact that dietary NDF concentrations ranged from 33.4 to 39.4% of the DM, which is a difference of 6 points. Moreover, greater forage to concentrate ratio and NDF concentration in the diet of cows fed saturated lipids led to lower postpartum DMI compared with cows fed whole flaxseed or a control diet. Therefore, the response to fat treatments was partly confounded by differences in the forage to concentrate ratios and dietary NDF concentrations of the 3 postpartum diets. Feed intake might have been at least partly limited by gut fill, especially for the 39.4% NDF diet that contained saturated lipids. Furthermore, much lower starch concentration in the diet containing saturated lipids very likely contributed to lower plasma glucose and greater NEFA concentrations for this diet. Comparisons of control (CO, no supplemental fat) and unsaturated lipids supplied as whole flaxseed (FL) to saturated lipids supplied as Energy Booster (EB; MSC, Dundee, IL) were confounded by different forage to concentrate ratios that likely affected response variables, although the comparison between CO and FL may still be valid. Indeed, cows fed the CO and FL diets had similar DMI after calving (P > 0.05), and NDF concentrations in CO and FL diets were also similar but some blood parameters related to fatty liver syndrome differed between these diets. Multiparous cows fed FL had lower concentrations of triglycerides than those fed CO or EB in wk 4 after calving. Moreover, liver glycogen concentration after calving was significantly greater for multiparous cows fed FL compared with those fed CO. There was no confounding effect between diets CO and FL because similar DMI for both resulted in differences for some parameters related to fatty liver syndrome. Finally, the objectives of the present experiment were to “determine the effects of feeding flaxseed, a rich source of n-3 FA, on liver concentrations of TG, glycogen, and total lipids, liver and blood profiles of FA, and plasma concentrations of NEFA, BHBA, FA, and glucose. Energy Booster, a source of saturated and rumen inert lipids, was compared with flaxseed to determine the effects of dietary lipids with different profiles of fatty acids.” Therefore, these objectives were met by the results reported by Petit et al., 2007Petit H.V. Palin M.F. Doepel L. Hepatic lipid metabolism in transition dairy cows fed flaxseed.J. Dairy Sci. 2007; 90: 4780-4792Abstract Full Text Full Text PDF PubMed Scopus (65) Google Scholar regarding the effects of flaxseed on blood and liver concentrations of different parameters and the conclusion goes along with the objectives.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
