EVALUATION OF THE PROGENY OF CREOLE ROOSTERS (Gallus gallus domesticus) WITH NAKED NECK AND ROSE COMB

Abstract

Objective: To evaluate the distribution of plumage [naked neck (Na) or normal (NN)] and the type of comb [simple (SC) or rose (RC)] in the progeny of creole roosters (Gallus gallus domesticus L.) with Na and RC.

Design/methodology/approach: A completely random design was used, two groups, each one consisting of a rooster with Na and RC, and eight hens NN with SC were used to evaluate the type of neck and comb, and initial weight of the progeny.

Results: The 53% of the progeny presented Na and 47% NN, while 81% showed RC and 19% SC. The initial live weight was similar in Na than in NN chickens and similar in RC and SC birds.

Limitations on study/implications: In the revised of the literature, little information was found on the progeny of creole chickens with naked neck and rose comb.

Hallazgos/conclusiones: Los resultados del presente trabajo demostraron que al cruzar gallos cuello desnudo y cresta rosa con gallinas cuello normal y cresta simple en su progenie se pueden observar ambos tipos de cuello y una mayor presencia de pollos con cresta rosa, sin presentar diferencia de peso inicial.

Findings/conclusions: The results of the present work showed that when crossing roosted naked neck and rose comb with hens normal neck and simple crest in their progeny, can be observed both types of neck and a greater presence chickens with rose comb, without presenting a difference in weight initial.
