1 · What the graph read from it

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.

2 · The registry

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

Modulating the milk fatty acid (FA) profile through dietary strategies is a key approach to enhancing the nutraceutical value of dairy products. This study aimed to elucidate how different basal diets, associated with forage cactus and a lipid source, interact to modulate the milk fat composition of lactating Saanen goats. Twelve multiparous goats, averaging 3.5 years of age and 48.9 ± 7.3 kg body weight, were allocated to a triple 4 × 4 Latin square design. The experimental treatments consisted of corn silage (CS), sorghum silage (SS), grass hay (GH), or sugarcane bagasse (SB), each associated with forage cactus and a concentrate containing full-fat corn germ (FFCG) as the lipid source. The fatty acid profiles of the ingredients in each diet and of the goat milk were determined by gas chromatography. Results revealed a clear metabolic dichotomy driven by the forage source. Silage-based diets (CS and SS) significantly (P < 0.01) increased short- and medium-chain FA, indicating a higher rate of novo synthesis. In contrast, GH and SB diets profoundly altered ruminal biohydrogenation (BH), increasing by 62% the concentrations of vaccenic acid (trans-11 C18:1) and consequently rumenic acid (cis-9, trans-11 CLA) (P < 0.01), without inducing milk fat depression. While GH and SB diets maximized CLA synthesis, CS and SS were more effective in enhancing omega-3 FA transfer, resulting in a more favorable n-6/n-3 ratio (P < 0.01). It is concluded that the forage source is a precision tool to modulate the milk lipid profile, allowing the production of either functional milk rich in CLA or milk with an optimized essential FA composition.
