Effect of stocking density and alpha-lipoic acid on the growth performance, physiological and oxidative stress and immune response of broilers.
Article in Asian-Australasian journal of animal sciences, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 41 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
objectiveThe study was conducted to evaluate the effect of stocking density and alpha-lipoic acid (ALA) on the growth performance, feed utilization, carcass traits, antioxidative ability and immune response of broilers.
methodsA total of 1530 22-day-old male broilers (Arbor Acres) with comparable body weights (731.92 ± 5.26) were placed into 18 cages (2.46 × 2.02 m) in groups of 75 birds (15 birds/m2, 37.5 kg/m2; LD, low stocking density), 90 birds (18 birds/m2, 45.0 kg/m2; HD, high stocking density) and 90 birds with 300 mg/kg ALA added to the basal diet (18 birds/m2, 45.0 kg/m2; HD+ALA, high stocking density + -lipoic acid); each treatment was represented by 6 replicates. The experimental period was 3 weeks.
resultsThe results showed that the high stocking density regimen resulted in a decreased growth, feed conversion ratio, carcass weight, thigh yield and bursa weight relative to body weight (P < 0.05) on d 42. The abdominal fat yield in the HD+ALA group was lower (P = 0.031) than that of the LD group at 42 d. The superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities in serum were increased, and malondialdehyde (MDA) content decreased after adding ALA product (P < 0.05) on d 42. Additionally, the serum concentrations of IgA and IgG were decreased (P < 0.05) and the level of diamine oxidase (DAO) was higher (P < 0.01) in the HD group on d 42.
conclusionThe high stocking density significantly decreased broiler growth performance, feed utilization and carcass traits, increased physiological and oxidative stress and induced intestinal mucosal injury. The supplementation of ALA product in broiler diet at 300 mg/kg may reduce the adverse effects of high stocking density-mediated stress by maintaining the antioxidant system and humoral immune system.
