Determinación morfológica y faneróptica de la gallina criolla de la zona noroccidental de la provincia de Pichincha.

Abstract

The present research was carried out in the northwestern area of Pichincha Province, where the morphological and phaneroptic characteristics of the Creole Hen were determined. A population of 132 birds was studied in-situ divided into 24 roosters and 108 hens, during 70 days of experimentation where two analyses were used for the results: the first analysis a Completely Random Design with 3 treatments (San Miguel de los Bancos, Pedro Vicente Maldonado, Puerto Quito) and 4 repetitions each treatment with an experimental unit size of 11 birds, the parameters to be evaluated were morphological such as: weight, LCb, ACb, LO, AO, LCr, ACr, LP, LC, LD, LY, AF, PT, LA, LH, LRe, LFa, LM, LP, CP, LCa, LDm, LE and in the second analysis it was descriptive statistics for phaneroptic parameters such as: feather color, beak color, crest type, tarsi color, skin color, appendage color, presence of feathers in the tarsi and production systems based on components such as: social, economic, food, health, reproductive, technological on productivity. Through the methodology applied it was possible to determine that in the males there were no statistical differences (P<0.05), in the color of feathers there is high phenotypic variability exceeding 30% in the three cantons and the dominant yellow skin coloration exceeding 50%. On the other hand, the frequency of diseases is very high, exceeding 90% due to lack of vaccination programs. The determination of the morphology of the Creole Hen showed that males could not be part of the formation of genetic nuclei, and factors such as space and socioeconomic status determine the management system. Therefore, it was recommended to carry out this type of research to learn more about the Creole resources of our country.
