Effects of varying levels of coated cysteamine hydrochloride in diet on growth performance and carcass quality of steers.
Article in Animal bioscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveThis study aimed to evaluate the effects of different levels of coated cysteamine HCl (CSH) supplementation on growth performance, carcass traits, and meat quality in Charolais crossbred cattle.
methodsTwenty-four Charolais crossbred steers, aged 24-30 months with an initial body weight of 418±31 kg, were assigned to three dietary treatments: 0% (control), 0.5%, or 1.0% CSH in concentrate. The steers were fed the experimental diets for 200 days.
resultsIncreased CSH levels in concentrate diets led to significant increases (p<0.05) in body weight, hot carcass weight, cold carcass weight, and dressing percentage. CSH supplementation decreased shear force values and cooking loss (p<0.05). Meat lightness was significantly greater in the 1.0% CSH-supplemented group (p<0.05). With increasing CSH levels, the proportion of high-value cuts, such as rib set and T-bone, increased (p<0.05), while the proportion of lower-value cuts, including macreuse, shank, and tendons, decreased (p<0.05). Non-carcass weights, including the feet, head, digestive tract, and scraps, were significantly higher in the 1.0% CSH-supplemented diet (p<0.05). The meat's chemical composition did not differ significantly among the treatment groups (p>0.05). Muscle fiber diameter was significantly larger in the 1.0% CSH-supplemented group (p<0.05). Monounsaturated fatty acids increased (p<0.05) with higher CSH levels, whereas polyunsaturated and saturated fatty acids exhibited a significant decrease (p<0.05).
conclusionDietary supplementation with CSH enhances growth rate, carcass traits, and meat quality in steers. An inclusion level of 1.0% CSH in concentrate is the optimum feeding dosage, demonstrating its potential as an effective feed additive for enhancing beef production efficiency.
