“…It also agrees with Mogesse [3] who reported some degree of relatedness existing among some local chicken types in Ethiopia. Our report also agrees with the report from Musa [14] which revealed that relatedness exists among the three indigenous chicken types In Nigeria.…”

Aim: This study investigated relatedness among three indigenous chicken types using morphological features and morphological trait interdependence within three indigenous poultry species in Nigeria. Study Design: A complete Random sample design was employed in this study to investigate morphological relatedness. Place and Duration of the Study: Birds of reproductive age were sampled from 12 states across Nigeria between February 2013 and November 2015. Methodology: Morphological traits were measured according to the FAO description. Nearest neighbor analyses (hierarchical cluster) were done using SPSS 23.0 version. Results: The nearest neighbor analyses showed that higher degree of relatedness exists between the wild type chicken and the frizzle feather indigenous chicken type in Nigeria. Traits interdependence was observed between and among the different morphological traits within the different poultry species. Conclusion: The characters measured could be of useful genetic importance that may play significant role as markers for selection or breeding programs for improved productivity under free range or scavenging feed resource-based production systems.

“…Physical and qualitative trait evaluation reflects the effects of genes, and the impact of the environment; and enhances the understanding of local adaptations, which impact performance [14,25]. Natural selection as well as mutations could throw up unique phenotypes, genes, and genotypes that have special adaptation and utility in specific environments.…”

The Nigerian indigenous chickens (NICs) are a critical component of the global animal genetic resources. They are distributed in rural areas, kept by the majority of the rural poor. They constitute different strains, or ecotypes local to tribes, regions, or ecological zones and are valued for their disease resistance, adaptation, and yield of valuable products and income on marginal inputs making them a low risk species. They are hence a unique and vital genetic resource and gene pool for present and long-term genetic improvement and human need for food and sustenance. The NIC is however; threatened by extinction owing to neglect, negative selection, breed substitution, and genetic introgression. There is need to draw research and policy attention to the conservation of NICs in accord with the global effort for the conservation of indigenous chickens which is probably the most neglected among farm animal species. The present review therefore, focuses on the physical and performance characteristics, genetic diversity and improvement, utilization and conservation of NIC genetic resources.

“…Some morphological characters such as morphometric traits are correlated with bodyweight (Ajayi et al, 2012). Thus, such morphometric traits could be used as markers in body weight improvement programmes and body weight predictors (Musa et al, 2018). However, correlations between body dimensions may be different if the dimensions are treated as bivariate rather than multivariate.…”

An experiment was conducted to determine the principal component analysis of body morphometric traits as affected by age and sex in donkeys reared on a research station in the National Animal Production Research Institute, Shika-Zaria, Nigeria. This was based on the objective of classifying age and sex using the multivariant method of principal component analysis (PCA) on morphometric traits of donkeys. Data were collected from a total of 101 donkeys based on age and sex on body wright, heart girth, body length, height at withers, tail length, shoulder width, head width, ear length, head length, neck circumference and neck length. The data obtained were subjected to multivariate factor analysis with varimax rotation using IBM® SPSS® Version 21. The results obtained revealed that the age group ≤ 1 year had one PCA, 2–3 years age group had four PCA, 4–5 years group had three PCA while those ≥ 6 years had two PCA. Most of the variables in combination with age largely formed the block of PC1 while other PCA had one or two variables correlating with them. Most of the variables formed PC1 for the Jacks while head width (HW) and ear length (EL) formed PC2. The Jennies had its entire variable in one PCA. Therefore, PC1 had the highest loading for the variables both by age and by sex as the animals are relatively well adapted to their environment. It can be concluded that donkeys between 2-3years have more PC correlation proportions.
