Genetic diversity and breed identification of Chinese and Vietnamese local chicken breeds based on microsatellite analysis.
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 4 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
South Asia and Southeast Asia are the origins of domestic chickens and are rich in poultry genetic resources, resulting in many unique local chicken breeds. However, with the rapid intensification of poultry farming worldwide, many local chicken breeds are threatened with extinction. In response to China's "One Belt, One Road" policy, it is imperative to strengthen the conservation and breeding of local chicken breeds in China and Vietnam. This study characterized 18 microsatellite molecular genetic markers to analyze the genetic diversity of 21 local chicken populations in southern China (Yunnan and Guangxi Provinces) and Vietnam, breed identification tags for microsatellite loci were constructed. The results showed that a total of 377 alleles were detected in all breeds, and the most alleles (44) and the highest polymorphic information content (0.7820) were detected at the LEI0094 locus. The average polymorphic information content (PIC) content of the whole population was 0.65, indicating moderate polymorphism. The genetic diversity of the whole population was rich, except for two loci MCW0111 and MCW0016, that showed heterozygote excess at microsatellite loci, and the population had high genetic differentiation. The Vietnamese breeds showed low pairwise fixation coefficient (FST) and Nei's standard genetic distance (DS) between them. According to the neighbor-joining dendrogram constructed by DS and the analysis of population genetic structure using the structure program, Longshengfeng chicken, Yunlong dwarf chicken, Tengchong white chicken, Xiayan chicken, and Daweishan mini chicken are similar, and Xishuangbanna game fowl, Wuding chicken, and Lanping silky chicken are similar to Yanjin black-bone chicken. In addition, excluding Dongtao chicken, other Vietnamese breeds are clustered together, indicating that the southern chicken breeds are closely related and have experienced better breeding. Overall, the whole population is rich in genetic resources, and the chicken breeds in the three regions are genetically close because of geographical factors and human activities. Dongtao chicken in Vietnamese, Chinese Yunnan local chicken breeds (Gallus gallus spadiceus), and red jungle fowl chickens (Gallus gallus) may have the same origin. We also constructed unique microsatellite molecular markers for 20 cultivars using 15 microsatellite loci. This study provides valuable insights to facilitate breed identification, improve cultivar protection, and new germplasm construction.
