Antioxidant and antinutritional potentials of sweet potato (Ipomoea batatas) leaf meal on the growth performance, economics of production, blood indices, carcass characteristics and histopathology of broiler chickens.

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
A feed trial on seven hundred-and twenty-day old Cobb-500 strain broilers finisher chickens on substituting sweet potato leaf meal (SPLM) in broiler chicken diets was conducted. In a completely randomized design, the birds were allocated randomly to five (5) diets with 144 birds per treatment and divided into four replicates of thirty-six birds each. Treatment 1 was designated as the control (0% SPLM) while 3.75% SPLM, 7.5% SPLM, 11.25% SPLM and 15% SPLM served as T2 - T5 respectively. Data were collected on blood indices, carcass characteristics and histopathology which were subjected to analysis of variance (ANOVA) and the means were separated using Duncan's Multiple Range Test. The proximate analysis and phytochemicals in the leaf revealed significant amounts of constituents analysed. The bird's performance, cost of production, blood indices, carcass, and organs characteristics on experimental diets recorded significant (p < 0.05) effects on the weight gain, FCR, cost of diets, cost of body weight gain, WBC, MCH, MCV, glucose and total cholesterol, live weight, plucked weight, eviscerated carcass weight and dressed carcass weight values. Treatment 3 had superior carcass values in comparison to the other treatments. The histopathology results recorded significant (p < 0.05) effects at 15%SPLM on the heart and liver respectively but no tissue damage was recorded. The superoxide dismutase enzyme exhibited the highest level compared to the other treatments. However, the level of the glutathione peroxidase enzyme significantly decreased in comparison to the other SPLM levels. Also, birds on SPLM supplements showed (p < 0.05) compared to the control. Conclusively, T3 revealed better weight gain, FCR and carcass quality while at higher inclusion levels up to 15% SPLM diet showed lowers values of production cost, serum cholesterol concentration, improves the serum superoxide dismutase and glutathione peroxidase activities of the chickens.
