“…The present study indicated that majority of the female chicken possessed single comb, which is in accordance with the findings of several studies from other developing countries (Egahi et al, 2010;Faruque et al, 2010;Apuno, Mbap and Ibrahim, 2011;Guni and Katule, 2013). The findings of Melesse and Negesse (2011) indicated that 55 percent of the chickens in Southern Ethiopia were characterized by single comb followed by rose (28.5 percent) and pea (15.2 percent) combs.…”

The objective of this study was to characterize the native chickens reared in three agro-ecological zones of Southeastern Oromia Regional State of Ethiopia. Data on visual appraisal and linear body measurements were obtained from a total of 600 matured local chickens of both sexes drawn from 240 households. The results indicated that the average flock size, age at first egg of hens and eggs produced per clutch were 11.9 heads, 6.2 months and 15.4 eggs, respectively. The majority of the male chicken possessed snake head shape (60.7 percent) and most of them had rose combs (57.9 percent), red feather plumage (46.1 percent), yellow shanks (86.3 percent), red earlobes (84.2 percent) and yellow skin (56.8 percent). Majority of the hens possessed single combs (43.5 percent), red earlobes (77.3 percent), yellow shanks (44.4 percent), yellowish brown feather (27.4 percent) followed by red (24.2 percent) and black (21.2 percent). The cocks were generally heavier (1.39 kg) than the hens (1.22 kg). The average values for breast angle (degrees), body length, body width, shank length, shank circumference, keel bone length, wing span, comb length and beak length of the cocks were 45.9, 24.1, 24.9, 7.43, 3.86, 9.63, 7.99, 4.86 and 1.91 cm, respectively. The corresponding values for the hens were 40. 2, 22.7, 23.8, 7.43, 3.46, 8.95, 7.40, 2.47 and 1.71. The values for wing span, comb length, beak length, body weight, breast angle and keel bone length differed (P < 0.05) across the agro-ecologies. The best predictor for assessing the body weight of hens was breast angle and body length, whereas in the cocks it was best estimated using breast angle and shank circumference values. The present study suggests that indigenous chickens in the study area possess useful economic traits that could be improved through systematic breeding for enhanced productivity under scavenging production systems. ResumenEl objetivo de este estudio fue caracterizar las gallinas nativas criadas en tres zonas agroecológicas del sudoriental Estado Regional de Oromía en Etiopía. Se recogieron diferentes datos por observación y por medidas corporales lineales sobre un total de 600 aves locales maduras, de ambos sexos, tomadas de 240 hogares. Los resultados indicaron que, de media, el tamaño de los grupos, la edad de las gallinas al primer huevo y los huevos puestos por nidada fueron respectivamente de 11,9 cabezas, 6,2 meses y 15,4 huevos. La mayoría de los machos presentaron cabeza con forma de serpiente (60,7 por ciento), cresta en rosa (57,9 por ciento), plumaje rojo (46,1 por ciento), tarsos amarillos (86,3 por ciento), orejillas rojas (84,2 por ciento) y piel amarilla (56,8 por ciento). La mayoría de las gallinas presentaron cresta sencilla (43,5 por ciento), orejillas rojas (77,3 por ciento), tarsos amarillos (44,4 por ciento) y plumaje marrón amarillento (27,4 por ciento), rojo (24,2 por ciento) o negro (21,2 por ciento). Por lo general, los gallos fueron más pesados que las gallinas (1,39 versus 1,22 kg). En los gallos, los valores medios de inclinac...

“…White earlobes were the most frequent (73.96 %) in the three regions, followed by red earlobes (16.81 %). This is consistent with the findings of other researchers (Roxas et al, 1996;Egahi et al, 2010;Faruque et al, 2010). White earlobe is a characteristic feature of chickens of the Mediterranean region (Sørensen, 2010).…”

“…A region effect was observed for this trait, due to a higher occurrence of black (P <0.001) and green colouring (P <0.05) and a lower occurrence (P <0.001) of white colouring in Mostaganem province (12.6 %). Our study thus highlighted the large variability in tarsus colour between local populations as previously studies reported more frequent white and yellow tarsi in the humid forest zone of Cameroon (Fosta et al, 2010) and in the districts of Jarso and Horro in Ethiopia (Desta et al, 2013) but more frequent black tarsi in Nigeria (Egahi et al, 2010) and Libya (El-Safty, 2012). The occurrence of various types of tarsus colours in this study might have been due to combinations of pigment-controlling genes responsible for colour determination.…”

Abstract. This study was conducted to characterize local chickens in the northwest of Algeria based on some phenotypic traits and to look at prediction of body weight from morphometric measurements (linear body). The results indicated that the predominant comb colour was dark red (77.8 %), followed by light red (22.2 %). Tarsus colour was either white (40.9 %), grey (31 %), yellow (15.39 %), dark (8.05 %), or green (4.51 %). Most chickens (81.7 %) had orange eyes, while 10.37 and 7.92 % had yellow and dark-brown eyes, respectively. The dominant earlobe colour was white (73.96 %), followed by red (16.81 %). The remaining proportion included yellow and red-mottled yellow and black earlobes. Proportions of the adaptive genes were low. Incidences of Na, F, Pti, Cr, R, and P genes were 8.82, 0.45, 1.22, 5.54, 3.35, and 4.7 %, respectively. The calculated gene frequencies ranged from 0.002 to 0.045. Variations were also found in quantitative morphological traits. Sex-associated differences (P <0.001) were observed in almost all the parameters evaluated with higher values recorded for males. Phenotypic correlations of body weight and biometric traits ranged from −0.13 to 0.88 and −0.15 to 0.97 for males and females, respectively. From the factor analysis with varimax rotation of the intercorrelated traits, three principal components which accounted for 71.6 and 73.2 % of the total variance were extracted in males and females, respectively. Orthogonal body shape characters derived from the factor analysis accounted for 84.3 and 94.2 % of the variation in body weight of males and females, respectively. Information obtained from this study could be useful in an appropriate management, breeding programmes for selection and utilization of Algerian chicken genetic resources.

“…Given the small number of samples available in other phenotypic categories, the real level of variation of comb type was hard to be speculated. The results on the trends of distribution of single comb were quite similar to the findings of Egahi et al (2010) in Markudi, Nigeria but different from those reported by Dana et al (2011). The dissimilarity in the occurrences of comb types may be attributed to differences in frequencies of alleles responsible for the comb types and interactions of different genes responsible for its expression.…”
