Influence of first colostrum pasteurization on serum immunoglobulin G, iron, and activity of gamma-glutamyltransferase in newborn dairy calves.
Article in Veterinary world, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
BACKGROUND AND
aimColostrum pasteurization is an established procedure in dairy farms in developed countries. This practice can improve the health status of the offspring by reducing several pathogens. This study aimed to focus on the pasteurization of bovine first colostrum and its influence on certain important bioactive components. MATERIALS AND
methodsThis study was conducted in Holstein-Friesian bull calves, which were randomly divided into two groups and fed with 6 L of untreated (UT, n=10) or 6 L of heat-treated (HT, 63.5°C for 30 min, n=10) colostrum from their own dam within the first 12 h after birth. Blood samples were taken before, 24 h, and 48 h after first colostrum intake to determine the concentrations of immunoglobulin G (IgG) and iron and the activity of gamma-glutamyltransferase (GGT) in the serum.
resultsThe level of IgG was not affected by pasteurization (p=0.19). However, a slower increase in GGT activity (p<0.05) and a lower serum iron concentration (p=0.04) were observed in the HT group.
conclusionIt can be concluded that pasteurization influences the absorption of colostrum components and therefore, the passive transfer of immunity, although the level of IgG was not affected by pasteurization in this study.
