摘要
Data on bodyweight and 11 body measurements were taken on 51 Fulani and 101 Yoruba ecotype chicken from two central poultry markets: Ilorin in the middle belt and Ibadan in the southwest regi車n of Nigeria, respectively. The aim was to provide baseline information on size characteristics of Fulani and Yoruba ecotype chickens, differentiate between the types and use the morphometrical variables for a preliminary assessment of type and function. Results showed that least square means of live weight, wing and shank length, body, thigh and toe length, beak length and breast breadth of the Fulani ecotype were generally higher (P %26lt; 0.01) than those of the Yoruba ecotype. The males were also superior (P %26lt; 0.01) to the females for comb, wing, shank length and breast breadth while live weight, toe and thigh length also differ (P%26lt; 0.05) within each ecotype. Thecomb of males was more prominent than those of the females. Coefficients of variation were very small signifying a monotypic condition and an almost equal opportunity of selection for type based on body parameters of the two ecotype chickens. The Fulani ecotype was bigger than the Yoruba ecotype chicken. The significantly longer (p%26lt;0.05) bodies of the Fulani suggests a departure in function between the genotypes. The Fulani chickens appear more closely suited for egg production than the Yoruba type. Their potential for developing a more adapted commercial stock and genetic improvement of the chickens for the regi車n andother implications of type on function are discussed. Los datos sobre peso corporal y 11 mediciones corporales se hicieron en 51 pollos ecotipo Fulani y 101 pollos ecotipo Yoruba de dos mercados centrales de aves de corral: de Llorin en el Centro y de Ibadan en la regi車n Sudoeste de Nigeria, respectivamente. El objetivo fue proporcionar informaci車n b芍sica sobre las caracter赤sticas de tama o de los pollos ecotipos Fulani y Yoruba, diferenciar entre los tipos y el uso de variables morfom谷tricas para una evaluaci車n preliminar del tipo y funci車n. Los resultados mostraron que las medias de peso vivo, longitud de ala y patas, cuerpo, muslos y pies, largo del pico y ancho del pecho del ecotipo Fulani fueron en general mayores (P %26lt;0,01) que las del ecotipo Yoruba. Los machos tambi谷n fueron mayores (P %26lt;0,01) a las hembras en la longitud de la cresta y ala, largo de la pata y ancho de pecho, mientras que el peso vivo, longitud del dedo del pie y el muslo tambi谷n fueron diferentes (P %26lt;0,05) dentro de cada ecotipo. La cresta de los machos fue m芍s prominente que las de hembras. Los coeficientes de variaci車n
