Abstract
A study was conducted for zoometric characterization of 508 adult hens (132 males and 376 females) from nine communities in three municipalities from Los Altos de Chiapas region (Chiapas highlands). Description was obtained by direct observation, weight and corporal measurements. Feathers colors is diverse, but the tonalities predominant are dark (68.3 %), brunettes (14.4 %) or white (10 %). The plumage is normal (97.8 %) or curled (2.17 %), with naked neck (6.29 %), feathered neck (93.7 %), feathered shank (8.66 %), fringed (35.8 %) and feathered cheeks and fringed (7.48 %). The comb shape is simple (87 %) or rose type (11.6 %). The skin was predominantly white (56.8 %) or yellowish (41.7 %). The eyes presented an orange (64.5 %) or yellow (21 %) color. The average weight of females was 1900 ± 376 g (CV: 19.8 %) and of males was 2280 ± 630 g (CV: 27.8 %). Measurements were larger in males whit high variability. High correlations between weight and thoracic perimeter for males and females were found. This variability involves a biological richness and may be a great potential for the creation of rustic productive lines for Los Altos de Chiapas region in the highlands of Chiapas, Mexico.
