Lipid profile analysis of donkey milk during the lactation.
Article in Frontiers in nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: From ancient times, donkey milk (DM) has attracted much attention due to its particular properties. Donkey milk is characterized by a high level of lactose and low levels of protein and fat. However, studies investigating lipid changes in DM during lactation are limited. Methods: The lipid profile of DM at different lactation stages was analyzed using lipidomics in this study. Milk samples were collected from six lactating Dezhou donkeys on days 1, 30, 60, 90, 120, 150, and 180 of lactation. Results: A total of 1,552 lipids were identified, belonging to 5 major categories and 21 subclasses. Glycerophospholipids (GP, 62.11%) and sphingolipids (SP, 22.94%) were the predominant categories. At the subclass level, phosphatidylcholine (PC, 27.26%), phosphatidylethanolamine (PE, 17.59%), and phosphatidylserine (PS, 6.77%) were the most abundant lipids. Significant variations in the levels of GP, SP, glycerolipids (GL), and free fatty acids (FA) were observed across lactation stages. Colostrum was rich in GP and SP, whereas mature milk contained more GL. Regarding FA, mature milk had a higher content of linolenic acid than colostrum, while colostrum was richer in carnitines. Fourteen lipids were identified as potential biomarkers for distinguishing between DM from different lactation stages. Discussion: These results indicate that the lactation stage significantly affects the lipid composition of DM. This study provides a detailed lipidomic profile of DM, which will facilitate its further development and utilization.
