Phenotypic characteristics of local chickens in Dass and Tafawa Balewa local government areas of Bauchi State, Nigeria

摘要

The study was conducted in Dass and Tafawa Balewa local government areas of Bauchi State, between January and April 2018 to determine some characteristics of local chickens. A total of400 matured chickens of mixed sex were used to determine the following morphometric traits; live weight (LW), wing span (IVSP), body length (BL), girth circumference (GC) and shank length (SHL). Most of the birds available for the study were normal feathered (80.75 %), single combed (94.50 %), orange eyed (81.50 %), hadwhite ear lobes (43.75 %), milky shanks (37.75 %) and red plumage (36.75 %), while the fewest types were frizzled (7.50 %), rose combed (5.50%), Brown eyed (2.50%), those with red ear lobes (22.75 %), ash shank (2.00 %), and blue plumage (1.00 %). Single combed (95.60%), orange eyed (84.10%) had white skin (98.60%) white ear lobe (44.50%), pink shank (36.00%) and red plumage (38.8%) and the fewest were rose combed (4.40%), brown eyed (1.10%), yellow skinned (1.40%), those with red ear lobe (22.31%), ash shanked (1.10%) and those with blue plumage (0.50%). Data generated on morphometric traits were analyzed using analysis of variance and Pearson's correlation analysis was used in the estimation of relationships among the measurements (morphometric traits). The overall mean of 1.67 kg, 43.19cm, 41.27 cm, 31.49 cm and 10.19 cm for LW, WSP, BL, GC and SHL were estimated. Sex had effect on all the parameters recorded. Males were significantly heavier than female (1.79 vs 1.55 kg; p<0.001) and had wider girth (p< 0.001), longer wings (p<0.05), body (p<0.01) and shank (p<0.05). Non-significant effect of location, genotype and qualitative body traits (comb type, plumage, eye. ear lobe and shank colours) were however observed on most parameters The correlation coefficients among the morphometric traits were high, positive and significant indicating that they can predict each other specifically during selection.
