Effects of increasing levels of benzoic acid fed to pigs on nitrogen utilization and metabolism affecting growth performance, ammonia emissions, and carcass characteristics.

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
The objectives of this study were to investigate the effects of increasing levels of benzoic acid (BA) on nitrogen utilization and metabolism affecting growth performance, ammonia emissions, and carcass characteristics, and to determine the optimal levels of BA for the growth performance and carcass characteristics when fed to pigs from weaning to market. A total of 480 pigs (6.0 ± 1.5 kg) were assigned to 4 dietary treatments in a randomized complete block design with initial body weight and group as blocks and were fed in 6 phases. Treatments included a basal diet with antibiotics (positive control, PC) and diets with 3 levels of BA (0.00%, 0.50%, and 1.00% BA) without antibiotics. The PC increased (P < 0.05) the average daily gain (ADG) and G:F during the overall period compared to no BA supplementation. Increasing levels of BA increased (P < 0.05) overall ADG quadratically (maximum at 0.53% or 7.5 g/d of BA). Increasing levels of BA increased (P < 0.05) overall G:F quadratically (maximum at 0.57% or 8.1 g/d of BA). Increasing levels of BA tended to increase (linear, P = 0.096) N digestibility and increased (linear, P < 0.05) N retention. The BA supplementation at 1.00% decreased (P < 0.05) urine pH and aerial ammonia emission from manure compared to no BA supplementation in the 24 h collection period. The BA supplementation at 1.00% decreased (P < 0.05) rate of change in aerial ammonia emission compared to no BA supplementation in the 24 h collection period. The PC increased (P < 0.05) shrink weight, hot carcass weight, and first rib backfat compared to no BA supplementation. Increasing levels of BA decreased (P < 0.05) loin color and marbling score linearly and increased (P < 0.05) the loin eye area quadratically (maximum at 0.59% or 8.1 g/d of BA). In conclusion, supplementation of BA in feeds enhanced growth performance, improved N utilization, reduced urine pH, reduced aerial ammonia emissions, and improved carcass characteristics of pigs. Supplementation of BA at a range of 0.53% to 0.59% (corresponding to 7.5 to 8.1 g/d of BA based on overall average daily feed intake) provided the optimal improvements in body weight gain, feed efficiency, and carcass characteristics when fed to pigs from weaning to market.
