Dietary Betaine improves the intestinal health and growth performance of heat-stressed growing rabbits in summer.
Article in Journal of animal science, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The main objective of this study is to explore how various amounts of Bet affect growth performance, nutritional digestibility, and intestinal health of growing rabbits under high-temperature environment in summer. A total of 150 healthy 35-d-old weaned QiXing meat rabbits (Germany White rabbit × Sichuan White rabbit) were individually assigned to five treatments, each with 30 replicates and one rabbit per replicate. The control group was fed with basal diet, while the experimental group received a basal diet supplemented with 0.75, 1.0, 1.5, and 2.0 g Bet/kg diet, respectively. During the whole experimental stage, all animals can eat and drink freely, and they were kept in the rabbit house with an average daily temperature of 30.11 ± 0.5 ℃ and a relative humidity of 71.02 ± 5.07%. The results showed that dietary supplementation with 1.5 g/kg Bet increased average daily gain and decreased feed to gain ratio from days 1 to 42 as compared to the control group (P < 0.05), adding 0.75, 1.0, 1.5, and 2.0 g/kg Bet increased average daily gain and average daily feed intake from days 22 to 42 (P < 0.05), and increased the nutritional digestibility of acid detergent fiber (P < 0.05). Furthermore, dietary supplementation with 1.0, 1.5, and 2.0 g/kg Bet reduced d-lactate content and diamine oxidase activity in the serum (P < 0.05). Compared to the control group, supplementation of 0.75 and 1.5 g/kg Bet improved glutathione peroxidase activities in the duodenum and ileum, adding 0.75, 1.0, 1.5, and 2.0 g/kg Bet decreased malonaldehyde content in the duodenum and jejunum (P < 0.05). Moreover, the supplement of 1.5 and 2.0 g/kg Bet upregulated JAM-2 and IL-10 levels in the jejunum (P < 0.05). In conclusion, supplementation with Bet in the diet improves the growth performance, nutrient digestibility, and intestinal health of growing rabbits under high-temperature environments, and the 1.5 g Bet/kg diet group has the best effect.
