Effect of chemically protected sodium butyrate on growth performance, serum indicators, rumen fermentation parameters, and microbiota of Gangba sheep.

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
objectiveThis study investigated the effects of chemically protected sodium butyrate (CSB) on growth performance, serum indicators, rumen fermentation parameters, and microbial communities in Gangba sheep.
methodsTwenty-four healthy 5-month-old male Gangba sheep with an initial body weight of 19.54±1.04 kg were randomly assigned to four groups and fed diets containing 0, 1.0, 5.0, and 10.0 g/kg CSB for 74 days. After a 14-day adaptation period, the daily feed intake of Gangba sheep was measured. Fecal samples were collected during the last 7 days of the trial, and serum and rumen fluid were sampled on the final day.
resultsCSB improved final body weight, average daily dry matter intake, and average daily gain while reducing the feed conversion ratio of Gangba sheep (p<0.05). In addition, CSB improved the apparent digestibility of crude protein, dry matter, and neutral detergent fiber (p<0.05). Furthermore, CSB increased serum immunoglobulin G levels while decreasing tumor necrosis factor-α levels (p<0.05). Meanwhile, CSB increased serum growth hormone-releasing hormone levels (p<0.05). Furthermore, CSB increased rumen fluid pH and concentrations of ammonia nitrogen, acetic acid, iso-butyric acid, butyric acid, and total volatile fatty acids, as well as activities of lipase and butyrate kinase (p<0.05). Besides, CSB enhanced the rumen microbiota structure by increasing the relative abundance of Fibrobacter, unclassified Oscillospiraceae, and Ruminococcus.
conclusionCSB improved immunological and hormone indicators, enhanced the rumen ecological environment, and increased feed digestibility and utilization, thereby promoting the growth of Gangba sheep. It is recommended to use a dosage of 5.0 g/kg dry matter for optimal growth performance and health benefits.
