“…Researchers have found hundreds of phenotypic and morphological differences in gallinas criollas living in the communities of Colombia, Cuba, Ecuador, Guatemala, Mexico, and Venezuela 38,39,40,41,42,43,44,45,46,47 . While more research is needed to determine the genetic diversity (not only phenotypic and morphological) of gallina criolla specifically in Guatemala, the scientific community has demonstrated great genetic diversity in gallina criolla in Colombia, Ecuador, and Mexico 48,49,50,51 .…”

The report "Selling Industrial Gallina Criolla Products in Guatemala" was funded by grants from the Tiny Beam Fund. The fund aims to support public research by academics studying the impacts of industrial food animal production in low-and middle-income countries. This report is the product of two Kindling Initiative grants awarded to Emory University for projects led by Dr. Yulia Chuvileva and others. This new report should not be confused with the original 2020 Guidance Memo on which it is based: DOI number 10.15868/social sector.36569. That Guidance Memo was supported with a Burning Questions grant awarded personally to Dr. Yulia Chuvileva. DISCLAIMEREvery effort has been made to ensure the accuracy of this text and the inclusion of all available information on the topics it addresses.

The study was conducted in the Bahi and Songea districts of Tanzania for sustainable use and conservation purposes. Blood samples of 100 indigenous chickens were collected and genotyped using eighteen microsatellite markers recommended by the International Society for Animal Genetics, Food and Agriculture Organization Advisory Group for Animal Genetics. Data were analyzed using GenAIEXv.6.5 software. Results showed that Bahi had a total of 117 alleles while Songea had 111 alleles. There were 6.5 alleles on average per locus for Bahi and 6.1 for Songea. The locus with the least number of alleles was MCW0078, with just 5 alleles, whereas the MCW0111F locus was highly polymorphic with 20 alleles. The mean number of different alleles (Na) was 7.250 ± 0.544 for Bahi and 7.000 ± 0.742 for Songea, with an overall average of 7.125 ± 0.515. The number of private alleles was 31 and 37 for Bahi and Songea, respectively. Genetic variation among the population was 17%, while within the population it was 83%. Nei’s genetic distance was calculated to be 0.589, and the principal of coordinate analysis (PCoA) revealed two clusters with some intermixes. At p < 0.05, divergence from Hard Weinberg equilibrium was significant in all loci. In conclusion, there was a considerable genetic variation between the two study populations hence, they are very useful in conservation programs of the indigenous chickens.

The sustainable usage and conservation of indigenous chickens require a genotypic characterization. This study was conducted in the Bahi and Songea districts of Tanzania. Blood samples of 100 indigenous chickens were collected and genotyped using eighteen microsatellite markers recommended by the International Society for Animal Genetics, Food and Agriculture Organization Advisory Group for Animal Genetics. Data were analyzed using GenAIEXv.6.5 software. Results showed that Bahi had a total of 117 alleles while Songea had 111 alleles.
