Establecimiento del manejo productivo de un grupo genético de gallinas criollas

Abstract

The low level of technology applied in the production of native poultry causes the waste of essential characteristics of this species, such as hardiness, adaptation, reproduction, and others. Thus, it is essential to propose production programs to preserve this bird population and avoid its possible disappearance. This research aimed to establish the productive management of a genetic group of Creole hens. The methodology applied evaluated quantitative and qualitative characteristics, using 42 Creole birds, 36 females and six males. Descriptive statistics (means, standard deviation, maximum and minimum values) were applied. Twenty econometric measurements and four phaneritic indicators (plumage color, skin, tarsus, and presence of feathers on the neck) were evaluated. In addition to the characterization of creole eggs (dimensions, weight of egg white, yolk, eggshell, and yolk pigmentation), the results recorded for the productive variables were initial weight (1093+234.798) g. final weight (1231.50 +214.82) g, total weight gain (167.08 ±190.538) g, total feed consumption (136800) g. feed conversion concerning gram of egg produced (44. 11), total egg production (133) U, egg production/bird/wk. (0.43+0.19) U, egg production/wk/housed bird (41.05 ± 18.15) %, total egg production/bird/day (6.42 ±0.13) %, total egg production/housed bird (6.16) %, average egg weight (23.32) g, weight of total eggs produced (3101) g, mortality (9.52) %, and carcass yield (62.32) %. It is concluded that the productive management of Creole hens would depend on factors such as age, physiology, and the adaptation process in which they and it was also determined that the birds of the genetic group, according to their characterization, are classified as light and laying birds, in addition to being agile, rustic, and fast animals.
