Effects of breeds and dietary protein levels on the growth performance, energy expenditure and expression of avUCP mRNA in chickens.
Article in Molecular biology reports, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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 physiological mechanisms of thermogenesis, energy balance and energy expenditure are poorly understood in poultry. The aim of this study was designed to investigate the physiological roles of avian uncoupling protein (avUCP) regulating in energy balance and thermogenesis by using three chicken breeds of existence striking genetic difference and feeding with different dietary protein levels. Three chicken breeds including broilers, hybrid chickens, and non-selection Wuding chickens were used in this study. Total 150 chicks of 1 day of age, with 50 from each breed were reared under standard conditions on starter diets to 30 days. At 30 days of age, forty chicks from each breed chicks were divided into two groups. One group was fed low protein diet (LP, 17.0 %), and the other group was fed high protein diet (HP, 19.5 %) for 60 days. Wuding chickens showed the lowest feed conversion efficiency (FCE) and the highest expressions of avUCP mRNA association with high plasma T3 and insulin concentrations. Hybrid chickens showed the lowest expressions of avUCP mRNA association with high FCE and energy efficiency. Expressions of avUCP mRNA association with diet-induced thermogenesis (DIT) were only observed in broiler and hybrid chickens. The expressions of avUCP mRNA were positive association with plasma insulin, T3 and NEFA concentrations. Age influence on the expression of avUCP mRNA were observed only for hybrid and broiler chickens. It seems that both roles of avUCP regulation thermogenesis and lipid utilisation as fuel were observed in the present study response to variation in dietary protein and breeds.
