Effect of different pasture species on growth performance, carcass traits, internal organ weights, and meat quality of slower growing broilers in free-range production system.
Article in Tropical animal health and production, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
This study examined the effect of Medicago sativa (A), Trifolium repens (WC), Lolium perenne (PR), and their mixture (Mix) on growth performance, carcass characteristics, internal organ weights, and meat quality of slower-growing broiler chickens in a free-range production system. The animal materials comprised of mixed-sex Hubbard ISA Red JA, which were reared in the deep litter system for the first 3 weeks, and thereafter, the pop hole in each of the indoor pens was opened to allow birds access to the range containing one of the above pasture treatments. The range availability was ensured from 08:30 a.m. to 4:30 p.m. The results indicated no significant difference in broiler live body weight, feed conversion ratio, and livability between 28 and 77 days among the pasture treatments (P > 0.05). No significant variations were observed in the carcass and internal organ weights among pasture types (P > 0.05). Additionally, while the dry matter content (P < 0.01), TBA value (P < 0.05), and fatty acid profiles differed (P < 0.01), the protein, ash, water holding capacity, and oxidation stability of broiler breast meat did not differ among pasture groups (P > 0.05). Moreover, while the values of breast meat lightness (L*) and brightness (b*) differed (P < 0.05), redness and pH did not differ between the sexes (P > 0.05). Furthermore, sex significantly affected ash, protein content (P < 0.05), and TBA value (P < 0.01) of breast meat but did not affect dry matter, water holding capacity, and peroxide value of breast meat. Also, there was a significant difference in the weight of the neck, breast, thigh, live weight, hot carcass yield, heart, liver, abdominal fat, and digestive system between sexes (P < 0.05). However, breast meat fat content and fatty acid profiles were not influenced by the sex of the broilers (P > 0.05). It was concluded that access to the studied pasture species has no effect on the growth performance traits but results in notable variations in the fatty acid profiles in broiler breast meat.
