Item Association of MC1R variation and plumage color diversity of Nigerian domestic pigeon (Columba livia domestica)(Journal of Advanced Veterinary and Animal Research (JAVAR), 2022) Xiang-Xiang, Jiang; Adeniyi, C.A.; Sola-Ojo, F.E.; Ibraheem, A.A.; Isiaka, H.F.; Ojuerayetan, J.O.; Abdulwahab, B.A.; Olawale, A.O.; Oladejo, H.A.; Oladipo, U.; Hussein, H.; Semiu, F.B.; Min-Sheng, Peng; Ya-Pring, ZhangObjectives: Domestic pigeons (Columba livia domestica) have diverse plumage pigmentations. Melanocortin 1 receptor (MC1R) gene variation has been correlated with color traits. The association between MC1R and plumage coloration in African domestic pigeons is yet to be investigated. Materials and Methods: Herein, we report the relationships between single nucleotide polymorphisms (SNPs) in MC1R and plumage of 35 domestic pigeons from Nigeria with 4 different plumage phenotypes plus 37 published MC1R sequences from France (n = 14) and Russia (n = 11). Results: We obtained 14 SNP sites among 72 individuals. Missense mutations C206T (Ser69Leu) and G253A (Val85Met) were observed in 16 and 8 Nigerian pigeons, respectively. The chi-squared test (p < 0.05) for C206T, G253A, and A520G has the advantage of homozygous genotypes CC, GG, and AA, respectively. The association of C206T loci showed the advantage of CC genotype in ashred, spread, and white pigeons, and TT in blue-bar, spread, and white feather pigeons. For G253A and A520G loci, GG and AA were dominant in all plumages except for genotype AA in G253A, which was prominent in ash-red, spread, and white plumages. The three SNPs were assigned to seven haplotypes. The median-joining network revealed 20 haplotypes, including 5 in Nigeria and 2 shared. Conclusion: This study provides an insight into the association of MC1R variation and plumage diversity in Nigerian domestic pigeons. However, due to the limitation of the current data, we could not make further conclusions; this necessitates the need for more genomics studies on Nigerian pigeons.Item Genetic diversity and relationship of Nigerian Muscovy duck populations(Korean Society of Animal Breeding and Genomics., 2021) Sola-Ojo, F.E.; Adeniyi, C.A.; Lameck, A.O.; Yusuff, O.A.; Momoh, E.O.; Adekoya, A.R.; Adedibu, I.I.Muscovy duck (Caraina Moschata) is an economically important species due its unique meat taste and low-caloric content. It is one of the domestic poultry species in Nigeria as it ensures food security to the rural sectors. Rearing of Muscovy is concentrated in some part of the country due to its peculiar nature as water loving poultry species and peoples belief. In this study, we analyzed the genetic diversity and relationship of Muscovy duck populations collected from 15 different locations where Muscovy duck lovers resides in four states (Kaduna, Kwara, Niger and Oyo) of Nigeria based on Nuclear DNA Cytochrome P450 Family 2 Subfamily U Member 1 (CYP2U1) gene. A total of 48 polymorphic sites consisting of substitutions with 33 singletons variables was observed. The 82 sequences were assigned into 32 distinct haplotypes. Haplotype diversity was 0.7925. The Phylogenetic analysis showed close clustering across all locations with the exception of BART 495, PAT 35 and KEY 764 individuals. The maternal genetic structure likely suggests the extensive genetic intermixing within the country. In addition, the differentiation of BART 495, PAT 35 and KEY 764 may be due to a certain demographic history and/or artificial selection that shaped its haplotype profile. The current data on Nigerian Muscovy duck genetic diversity based on nuclear DNA CYP2U1 gene do not permit us to make further conclusions; therefore, more research evidence from genetics and archaeology is still required.Item Mitochondrial DNA variation of Nigerian Muscovy duck (Cairina moschata)(Wiley & Sons, Inc., 2020) Adeniyi, C.A.; Muslim, K.E.; Lotanna, M.N.; Oguntunji, A.O.; Semiu, F.B.; Sola-Ojo, F.E.; Adeola, O.A.; Oscar, J.S.; Daniel, L.E.; Kingsley, N.J.; Xinzheng, J.; Ru-Nian, W.; Min-Sheng, P.; Ya-Ping, Z.Item Molecular Sexing and Taxonomic classification of Nigerian Guinea Fowl using Chromo Helicase DNA Binding Gene and 12S mitochondrial rRNA gene.(The Korean Society of Animal Breeding and Genomics., 2021) Sola-Ojo, F.E.; Afolabi-Balogun, N.B.; Adeniyi, C.A.; Adeyemi, K.D.; Ayorinde, K.L.; Alli, O.I.; Oni, O.A.; Okeke, C.U.; Momoh, E.O.; Adewara, J.; Abdulkareem, I.Sexing of birds at early age is very important for efficient selection and breeding; while characterization and taxonomic identification is relevant in conservation of birds’ genetic resources. This study used the genomic DNA of ten (10) guinea fowl keets to determine their sex using agarose gel electrophoresis and sequencing with chromo helicase DNA (CHD) binding genes, they were also characterize taxonomically using 12S rRNA mitochondria genes. The results of this study shows a double band (ZW) for females and a single band (W) for males under Agarose gel electrophoresis view, the Guinea fowl keets sequenced showed some deletions and were closer to Gallus_CHD12 in the phylogenetic tree. The Taxonomic classification result shows that the sequenced guineafowl keets were most related to the Numida meleagris 12S mitochondrial ribosomal RNA. This study corroborate the fact sex of guineafowl keet can be easily identified at genomic DNA level and they can be characterized taxonomically using the 12SrRNA mitochondrial genes.Item Phenotypic, Physiological and Blood Profile Characterization of Muscovy Ducks (Cairina moschata) In North Central Nigeria(Department of Biology. University of Tlemcen. Algeria., 2020) Sola-Ojo, F.E.; Adeniyi, C.A.; Yusuff, O.A.; Abiola, J.Animal genetic resources (AnGR) are important to all future developments and adaptations. The concept has an international obligation to conserve certain characteristics of domestic animals for sustainable and future use. Characterization of indigenous Muscovy duck (Cairina moschata) would provide information for AnGR and also aid in conservation of ducks for future use. Two hundred (200) Muscovy ducks obtained from five (5) geographical locations in North central Nigeria were characterised using qualitative traits, physiological parameters, blood profile and quantitative traits. The results showed that 52.50, 54.00, 51.50, 50.00, 45.00 and 35.50% of the Muscovy ducks in the study area had black colour with respect to their general body plumage, shank, bill, web, eye, and bean, respectively. 50.00% were of horizontal body carriage, 90.50% had palmate web type, and 95.00% had no crest while 62.50% had caruncles. Sexual dimorphism existed between male and female with drakes having significantly (p<0.05) higher values compared to ducks in all the quantitative traits measured. Physiological parameters were not significantly (p>0.05) different according to sex and origin of the Muscovy duck studied. Comparison of the ducks by origin showed significant (p>0.05) differences in body weight, shank diameter, keel and wing length, and also in white blood cells, lymphocytes, red blood cells and mean corpuscular haemoglobin concentration, platelets and glucose. The information obtained here can serve as a guide on decisions concerning the conservation and development of selective breeding strategies for improvement of Muscovy ducks in the studied area.
