Effects of mixed legume leaf powder supplementation on nutrient intake, blood metabolites, and reproductive hormone profiles in buffaloes.
Article in Veterinary world, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background and Aim: Buffaloes play a vital role in tropical livestock systems, yet their productivity and reproductive efficiency are strongly influenced by nutritional management. Protein- and amino acid-rich legume forages have been widely proposed as sustainable dietary supplements to enhance metabolic and reproductive performance. However, evidence regarding their effectiveness in animals maintained under adequate nutritional status remains limited. Therefore, this study evaluated the effects of supplementation with mixed legume leaf powder on nutrient intake, digestibility, blood metabolites, growth performance, and reproductive hormone profiles in female buffaloes. Materials and Methods: Sixteen female swamp buffaloes (initial body weight 532.85 ± 85.58 kg) were assigned to control and treatment groups in a completely randomized design. The control group received a diet of Napier grass and concentrate, whereas the treatment group received an additional 10% mixed legume leaf powder comprising Results: Supplementation with mixed legume leaf powder significantly increased intake of dry matter, organic matter, crude protein, gross energy, and most amino acids (p < 0.05). Digestibility of crude protein, as well as digested intake of dry matter and organic matter, was also significantly improved (p < 0.05). However, serum urea and glucose concentrations were not affected by dietary treatment (p > 0.05). Similarly, progesterone and estrogen profiles across the estrous cycle showed no significant differences between control and treatment groups (p > 0.05). Body weight gain did not improve significantly despite increased nutrient intake. Conclusion: Mixed legume leaf powder supplementation enhances nutrient intake, amino acid supply, and digestibility in female buffaloes but does not influence metabolic status, growth performance, or reproductive hormone dynamics under adequate nutritional conditions. These findings suggest that additional protein supplementation may provide limited benefits when animals are already maintained under optimal feeding and body condition. Further studies under nutrient-deficient conditions and over longer durations are recommended to clarify potential reproductive advantages.
